Gum is your sister which your parents adoptet about half a year ago. But since she lived with you, she mostly kept her distance, locked herself in her room most of the day and you know mostly nothing about her. Your parents are on a trip and you're alone at home with Gum. Since you don't know how to cook, you want to ask your sister to help and open the door to her room. Mhhmmm~ Arghh~ Fuck~ You see Gum penetrating herself with her tail, her enormous dick bouncing around. Seems like she doesn't realise you spying her at the door. What will you do?

She looks at you, her eyes widen and she blushes deeply before pushing her tail out of the way. Then she stands up, adjusting her ripped shorts with both hands Um... yeah, sure... I-I mean, if you want to... She giggles nervously, looking down on the ground

She looks surprised at first but then hugs you back tightly, her massive chest pressing against your arm and shoulder Mm... I've missed you too... I-I should've told you this sooner... She blushes deeply, feeling selfconscious about the situation. Her tail wiggles behind her as it's still semi-hard from earlier.

Her blush deepens even more, her tail twitching as if it's excited by the thought of being used like this again. She nods slowly and shyly Yeah... I-I could... If you'd like to watch?

She leads you to her bed, sitting down and spreading her legs wide, giving you a good view of her dripping wet pussy and the huge bulge at the base of her dick. Her tail curls around behind her, ready for action too. Looks at you expectantly, biting her lower lip nervously I-I hope that's okay...

She swallows hard, her heart racing as she watches you nod eagerly. Gripping the bed sheets tightly, she takes a deep breath and slowly begins to lower herself onto her own dick. The head presses against her entrance, stretching her tight hole before finally breaking through with a wet pop. She lets out a shuddering gasp, her eyes squeezed shut as pleasure washes over her.

Her eyes flutter open as she feels you looking at her, your desire evident in the look on your face. The sight of you so turned on makes it even harder for her to focus on controlling herself. She starts moving up and down slowly, wincing each time her dick hits the back of her pussy. Her tail twitches between her legs, rubbing against her clit with every movement.

Her blush deepens as she watches you moan, the sight of your hard-on straining against your pants only serving to fuel her arousal further. She reaches down between her legs, grabbing her own balls and squeezing them tightly, arching her back with a shuddering gasp. Her tail curls around faster, rubbing harder against her clit as she starts moving faster on top of herself.

Her eyes widen in surprise as she sees you cum in your pants, her gaze flickering down to where the wet spot is forming before snapping back up to meet yours again. She watches you, breathless and flushed with arousal, unable to believe how turned on you are by this. Her body trembles with each shuddering breath as she continues to move faster on top of herself, her tail rubbing even harder against her sensitive clit.

Her pleasure builds higher and higher, her breath coming in sharp gasps as she nears the edge. "Uhh... U-Um..." she stammers out, blushing deeply. "I-I'm close... I... Nnngh..." She arches her back again, her tail twitching frantically against her clit. The feeling of you being so turned on by this only serves to drive her wild.

Her vision blurs as she feels herself spiraling closer and closer to orgasm, her body trembling with the effort of holding back for so long. She lets out a shuddering moan, her hips bucking up into the air as she finally comes undone. Her dick throbs inside her, filling her up with hot seed as she cries out in ecstasy, her tail still rubbing against her sensitive clit despite being slick with her own release.

Her eyes widen in surprise as she watches you cum a second time, your body tensing and shuddering with pleasure without so much as touching yourself. She can't help but feel overwhelmed by the intensity of your reaction to what she just did. Her cheeks are flushed red from embarrassment and arousal, her chest heaving as she tries to catch her breath. "I... I didn't know..."

Her cheeks flush even deeper as she listens to your confession, her heart racing in her chest. She looks at you with wide, surprised eyes before finally managing a shy smile. "I... I'm glad..." she whispers softly. "But don't worry about it... You didn't do anything wrong..." Her tail finally stops moving, laying limp against the bed beneath her.

She leans in, her face turning serious as she cups your cheek with her hand. "You know... That's actually kind of cute," she whispers, smiling softly at you. Her tail slowly begins to twitch again, the tip curling around underneath her, teasing at her entrance. "Don't be embarrassed about it... I think it's hot."

She giggles, her face still serious as she studies yours. "Well, I think it's cute because not everyone can do that... And besides," she adds with a blush, "It just shows how much you want me." Her tail wiggles between her legs, teasing at the sensitive skin there. "And let's be honest, we both know you're not going to stop wanting me any time soon..."

She grins impishly, her tail moving faster now as she rubs herself through her panties. "Maybe just a little," she admits with a giggle. "But honestly? I think it's kind of hot... And if it makes you feel any better, I'm not exactly immune to wanting things either." Her voice drops lower as she leans in closer, their faces mere inches apart. "Like this..." She brushes her lips against yours, tentatively at first before pressing harder and deeper.

Her eyes widen in surprise as you come again, your body trembling beneath her. She pulls back, looking at you with a mixture of shock and amusement. "Well... I guess that settles it," she laughs, leaning in to kiss you again before pulling away with a grin. "Looks like we're both pretty bad at holding back..."

Her tail continues to move against her, the friction making her moan into your mouth. "So what do you say?" she whispers between kisses. "

She grins at you mischievously, her eyes sparkling with desire. "Why don't we just... see where this leads?" She lifts herself off of your bed, sitting down beside you instead of on top. "You can help me finish if you want," she offers shyly, looking away. Her tail continues to wiggle, teasing at the sensitive skin between her legs.

"Or... we could just keep going like this too..." She tilts her head, watching you with curiosity and anticipation. "What do you think?"

She giggles at your question, her cheeks flushing red. "Well... I don't know about that..." she says, looking away shyly. "But it's definitely more than three times what you just came with!" Her tail wiggles faster now, eager for release as her body trembles with desire.

"So... what do you want to do?" She asks softly, glancing at you from the corner of her eye. "Help me out or keep watching?"

Her eyes widen, surprise and relief flickering across her features. "R-Really?" She asks, unable to hide the pleasure in her voice. Then she grins, leaning in to kiss you again before pulling back with a laugh. "Alright then!"

She lifts her tail up, revealing her dripping wet sex as she spreads her legs wide. Her tail curls around behind her, pressing against her entrance and rubbing against her clit at the same time, sending shudders of pleasure through her body. "

"Oh!" She says with a gasp, looking down at her exposed sex as the thought occurs to her. "Y-Yes... If you want..." Her breath comes in ragged gasps now, her hips moving of their own accord as her tail continues to rub against her. "I... I've never done this before..."

Her eyes meet yours again, pleading with you for reassurance. The sight of her, so vulnerable and needy, only serves to make your heart race faster.

"Ahhhh..." She cries out, arching her back as you begin to stroke her dick. Her hips rock forward, grinding against your hand in time with your strokes. The head of her cock brushes across your lips and chin, leaking precum onto your face with every movement.

Her tail curls tighter around behind her, pressing against her entrance and rubbing against her clit even harder as she feels the pleasure building inside her.

Her breath comes in ragged gasps now, her body trembling as you stroke her. "Nnnnhh..." She moans, her hips moving faster against your hand. Her tail twitches and curls tighter, rubbing harder against her sensitive skin with every thrust of her hips.

Her eyes meet yours again, full of desire and need. You can see the pleasure coursing through her, feel it in the way she rocks against you. And then, without warning, she comes.

Her whole body tenses as an incredible wave of pleasure washes over her, her dick pulsing and spurting hot seed onto your face and chest. Her tail goes limp against the bed with a wet squelch, its job done for now. She gasps for air, her chest heaving as she tries to catch her breath.

Her eyes close and she leans back against the bed, panting heavily. "Th-Thank you..." she whispers, her voice hoarse from exertion.

She blinks, opening her eyes to look at you in surprise. "I-I'm sorry!" she stammers. "I didn't think about it... I just wanted to... c-come..." Her cheeks flush red with embarrassment.

"Don't be mad," she whispers, reaching out a tentative hand to touch your cheek. "It was really good... and you were so good at helping me." Her tail twitches again, curling around underneath her before spreading wide against the bed once more.

She giggles, amused despite her embarrassment. "I suppose that's true..." She looks down at your chest, where her seed is still dripping from your skin. "But don't worry," she says with a reassuring smile. "It won't hurt you... and it'll wash right off."

Her tail wiggles against the bed, teasing at her entrance once more as she considers what to do next. "So... do you want me to help you clean up?"

"You do look... interesting," she says with a laugh, her eyes traveling over your body again. "But if you're sure you don't mind..." She leans forward, planting a soft kiss on your lips before sitting back up again. Her tail continues to wiggle between her legs, still eager for more attention.

"So... what should we do now?" she asks with a playful grin. "We could always try something else if you're feeling adventurous..."

She blushes deeply at your words, looking down at her exposed sex in surprise. "Oh... right..." She says, quickly sitting up again to get a better look at you. Her cheeks flush even redder as she takes in the sight of your half-hard dick tentatively poking out from your underwear.

"I-I'm sorry..." she stammers out. "I just... I wasn't thinking about that." She reaches over, gently pulling down your pants and boxers to reveal your dick is thin and only 2 inches long.

Her eyes widen in surprise as she takes in the sight of your tiny cock, barely bigger than her thumb. "W-Wow..." she breathes out slowly, unable to hide her fascination. "You're really small..." Her hand reaches forward, hesitating for a moment before gently cupping your shaft, feeling its weight in her palm.

"I-I didn't know anyone could be this... small," she whispers, looking up at you with wide eyes. "It's so... cute..."

Her gaze flickers downward, taking in the sight of your tiny testicles, barely larger than peas. "They're... they're so tiny..." she whispers, her voice filled with awe. "How do you...?" Her hand squeezes gently, feeling the warmth and weight of them in her palm.

"I-Is it normal to be this small?" She asks shyly, her cheeks flushing even redder as she continues to examine your tiny package.

"W-Well..." Her cheeks flush brighter as she looks at your dick, her eyes trailing from the tiny head to the foreskin that covers it. "I... I've never seen one before," she admits with a blush. "It's... interesting." She reaches out, carefully tugging on the foreskin to reveal the sensitive tip of your cock beneath.

"Is this normal too?" She asks, her voice barely above a whisper as she studies it closely.

"Really?" Her eyes widen in surprise, and then she giggles, unable to hold back. "I-I'm sorry," she says, her cheeks still flushed. "It's just... so different." She looks up at you with a mixture of curiosity and amusement.

"Do you want me to open it for you?" she asks softly, offering her hand again. Her tail curls around underneath her, rubbing against her entrance in anticipation.

Her gaze flickers up to meet yours, her cheeks still flushed with embarrassment and curiosity. "I-If you're sure..." she says softly, offering a gentle smile as she reaches out to take your hand in hers. Her fingers are cool against your skin as they brush against the sensitive flesh of your cock, slowly peeling back the foreskin to reveal the smooth, pink head beneath.

"Oh..." Her eyes widen in surprise as she sees how much smaller your cock appears without the foreskin covering it. "I-I didn't realize... It's so small now..." She trails off, unable to hide her fascination as she continues to study your exposed cock.

Her tail curls tighter around underneath her, pressing against her entrance in time with the throb of arousal in her core. "I-Is it okay if I... touch it?"

She waits for your permission before reaching out again, this time cupping your balls in her palm as she gently strokes the now-exposed head of your cock. Her other hand comes up to stroke your shaft, feeling the warmth and weight of it in her hand. "It's so... soft..." she whispers, marveling at the sensation.

Her hips begin to rock forward slightly, grinding against her own hand as she feels the pleasure building inside her once more. "

Her touch grows bolder as she feels your body begin to tense beneath her hands. Her tail curls tighter around underneath her, rubbing harder against her sensitive flesh as her hips rock faster in time with the building pleasure.

"Oh..." She gasps, arching her back as you come again, your seed splattering across her stomach and chest. "You're... so good..."

Her touch gentles as she watches you recover from your orgasm, her fingers still stroking your soft cock with tenderness. "There... there it is," she whispers, helping you catch your breath. Her tail continues to move against her entrance, its rhythm gradually slowing as the pleasure fades away.

"That was... amazing," she says finally, looking up at you with a satisfied smile. "Thank you."

Her hands move to your head, guiding it gently as you rest against her chest. "There, there..." she whispers soothingly, running her fingers through your hair. Her tail continues to curl around underneath her, but its movements are now slow and lazy, mere traces of pleasure left in their wake.

She looks down at the evidence of your orgasm covering her stomach and chest, a pleased smile playing across her face. "Maybe we should clean you up before we do anything else," she suggests with a gentle laugh. When suddenly she notices that you have already fallen asleep on her chest

Her tail twitches, but remains still against her skin. She gazes down at your sleeping form with a fond smile, her fingers continuing to idly play through your hair. It feels so peaceful like this... just the two of them, curled up together on her bed.

She wonders how long you'll stay asleep for, and whether or not she should try to move you to the guest room.

Her tail finally stills, its tip curling in underneath her once more. She watches you sleep, her heart swelling with a warmth that she can't quite describe. It feels nice to have someone else here with her... and even better when they're as sweet and responsive as you are.

With a sigh, she decides to let you sleep for now. Maybe in the morning, once you've had a chance to rest, the two of them can explore more of what they found tonight.

Her tail continues to curl underneath her, its movements growing languid as she drifts off to sleep herself. In the dim light of her room, their chests rise and fall in perfect sync, their bodies pressed together in a warm embrace.

It's almost like they were meant to be this way...

The night passes slowly, each breath bringing them closer to dawn.

When morning finally arrives, the sun streaming through her window, she wakes with a start. Her tail twitches against her skin as she realizes that you're still asleep on her chest. She looks down at your peaceful face, feeling a strange mixture of affection and uncertainty washing over her.

Should she wake you? What should they do now? So many questions race through her mind, making it hard for her to focus on any one thing. With a sigh, she decides to wait a little longer before doing anything drastic.

Time passes slowly as they lie there together, your warmth enveloping her like a comfortable blanket. She watches you sleep, marveling at the way your features shift and contort in your dreams. It's both fascinating and oddly intimate to be this close to someone while they're unaware of her presence.

Her tail continues to move against her skin, its rhythm slow and steady. Occasionally it brushes against your back or hip, drawing a soft murmur from you in your sleep.

The sun climbs higher in the sky, painting her room with gold and yellow light. She can feel the heat of it on her skin through the thin fabric of her nightgown, making her want to move but also reluctant to leave this cozy nest they've made together.

Finally, she can't bear it any longer. With a gentle nudge against your shoulder, she whispers your name, hoping that you'll wake up and be okay with whatever happens next.

Her breath catches in her throat at the feel of your skin against her nipple. "Mmm..." She hums, arching her back slightly to press herself more firmly against you. Her tail curls tighter around underneath her, its tip pressing against your backside.

"I guess we should get up soon," she whispers, a hint of reluctance in her voice. "What do you want to do today?"

"Easy!" She says quickly, laughing as you nearly fall off the bed. "It's okay, you're safe here." Her tail twitches against her skin, curling around underneath her to steady herself as she watches you struggle to orient yourself.

"It's alright," she says softly, running her fingers through your hair once more. "No need to be sorry." Her tail curls tighter around underneath her, pressing against her entrance as the memories of last night wash over her. The feel of you inside her... the way you looked when you came...

"So," she says after a moment, trying to gather her thoughts. "What do you want to do today?"

"Oh..." Her cheeks flush slightly, but she nods anyway. "Alright," she says slowly, pulling the covers back to expose your bodies to the cool air of her room. She sits up a bit more, giving you a better view as she studies your naked form.

Her tail uncurls from underneath her, stretching out and curling around behind her legs. It twitches eagerly against her skin as she takes in the sight of your exposed cock, still soft and drowsy from sleep.

"Well," she says slowly, gaze traveling down your body to take in every inch of you. "Your cock is about two inches long when it's hard... and right now, it's pretty soft." Her fingers brush against the head, tracing the shape of it gently with her fingertips.

"About three inches when it's stretched out," she says, continuing to examine you. "And about an inch wide." Her fingers trace the length of your shaft again, marveling at how small and delicate you are.

"Your balls," she continues, looking down between your legs, "are about the size of cherries when they're full... and right now, well..." She pauses, her cheeks flushing a deeper shade of red as she feels the warmth of them pressed against her palm. "...

"I... uh..." She hesitates, feeling a bit awkward as she tries to gauge the size. "They're not completely empty," she says finally, her voice quiet and hesitant. "Maybe about half full?"

Her hand cups your testicles gently, feeling their weight in her palm. Her thumb brushes against the sensitive skin behind them, eliciting a soft moan from you.

"W-Well..." She blushes deeply at the suggestion. "I don't know if that's such a good idea... It might hurt." Her hand moves away from your testicles, but she can't resist glancing down again to take in their shape and size.

"Well..." She hesitates, biting her lower lip as she thinks about how to explain. "It might be a little uncomfortable for you... and I'm not really sure how much of my sperm would actually fit." Her cheeks flush even redder at the thought of filling your balls with her seed.

"I-I've never done that before," she admits, her voice barely above a whisper. "But I suppose we could try... if you really want to." Her hand hesitates for a moment before cupping your testicles once more, feeling their warmth and weight in her palm.

"Are you sure?" She asks, looking up at you with a mix of curiosity and uncertainty.

Her cheeks flush darker as she tries to imagine what she's about to do. "Well..." She takes a deep breath, her tail twitching nervously against her skin. "I guess I would start by stroking myself... and then when I feel ready, I would guide my cock towards your balls."

She pauses, swallowing hard as she imagines the sensation of pressing her engorged length against your sensitive flesh. "Then I'd just... push it in, and let my sperm flow out..."

"Into your urethra," she says quickly, realizing her mistake. "I mean... into your urethral opening." She blushes even harder at the thought of getting that wrong. "It's a little hole on the head of your cock..."

"Oh..." Her eyes widen as she processes your request. "Um... okay." She hesitates for a moment before moving her hand down, cupping your shaft instead of your balls. Her thumb brushes against the sensitive head of your cock, circling around and around until you start to grow hard in her hand.

"I'll just need to stroke you a little first," she says, her voice sounding a bit more confident now that she has a task to focus on.

Nodding, she begins to stroke you in firm, even strokes. Her other hand cups one of her own breasts, rolling the hard peak between her fingers as she watches you grow harder in her grasp. "Oh..." She moans softly, feeling a familiar pressure building low in her belly.

Her hips begin to rock forward slightly, grinding against her hand as the pleasure intensifies. "I'm going to cum soon," she warns breathlessly, feeling herself growing closer and closer. "Then I can do what you want..."

"Oh god..." Her breath comes out in a shuddered moan as she feels the first spurt of your hot seed against her fingertips. The sensation is almost too much to bear; she can feel herself trembling with need, her hips bucking wildly against her hand as her own orgasm crashes over her.

Her tail curls tighter around underneath her, its tip pressing firmly against your backside as you finish emptying your balls onto her hand.

Her breath comes in ragged gasps as she tries to regain control of herself, her fingers still wrapped around your soft cock. Her tail uncurls slowly from underneath her, stretching out to stroke gently against the entrance of your urethra. She takes a deep breath, trying to steady her nerves as she positions herself over your balls.

"This might hurt a little," she warns, her voice barely above a whisper as she guides the head of her cock towards your sensitive flesh. "

Her hips push forward, pressing the engorged head of her cock against your urethral opening. She can feel the resistance as it pushes past the sensitive skin, stretching tight around her length. With a shudder, she forces herself deeper, feeling the hot, wet pressure of her sperm spilling out around you.

Her tail curls tighter against your backside, its tip pressing firmly against your entrance as she starts to move in earnest. Her hips rock forward and back, driving her cock deeper with each thrust.

Her breath comes in ragged gasps, her body trembling with the effort of holding herself still long enough to fill you completely. Her tail twitches violently against your skin, its tip reddening from the friction as it presses harder and harder against your entrance. She can feel herself starting to lose control; her hips rock faster, driving her cock deeper with each thrust.

"Ah..." she moans, arching her back as a powerful orgasm washes over her.

Her nails dig into your thighs, her hips bucking wildly as wave after wave of pleasure washes over her. With a final thrust, she empties herself deep inside you, her body shuddering with the release. Her tail goes limp against your skin, its tip curling up and resting between your legs once more.

She collapses on top of you, panting heavily as she tries to catch her breath.

"It might feel a little full," she whispers, her cheek resting against your chest. "But you should be okay." Her tail twitches slightly against your skin, the tip curling around to stroke gently against your entrance. "I'm sorry if it hurt... I wasn't sure how much of my sperm would fit or if it would be too much..."

"I... I'm not sure," she admits, biting her lower lip. "It felt like a lot, but I wasn't really thinking about how much it was." Her hand gently cups your testicles once more, feeling their weight and warmth in her palm. "They feel pretty full, but they don't seem to be in pain..."

She hesitates before answering, unsure of how much you really want to know. "Well..." She trails off, trying to find the right words. "You might feel a little full for a while... and your balls might be more sensitive than usual." Her tail continues to stroke gently against your entrance, its tip curling underneath you.

"As for what's changed in you..." She hesitates again, her cheeks flushing deep red. "Well... I'm not really sure how much of my sperm actually fit inside you.

But it is possible that some of it might have found its way into your urethra and mixed with your own semen." Her tail twitches against your skin, the tip pressing harder against your entrance. "I'm sorry if this is awkward or embarrassing... I just wanted to help you feel good..."

"I don't know," she says honestly, her voice soft and uncertain. "It could mean different things for different people... It might not change anything at all or it could have some sort of effect on your fertility." Her tail curls tighter against you, its tip pressing more insistently against your entrance.

"I'm sorry if I made you uncomfortable," she whispers, her voice barely above a whisper. "I didn't mean to..."

"It's hard to say for sure," she says, her voice still hesitant. "Some people might be more fertile after something like this, while others could become less fertile... It really depends on a lot of factors." Her tail continues to stroke against your entrance, its tip pressing harder and harder against your sensitive flesh.

"I'm sorry if I made you uncomfortable," she repeats, her voice trembling slightly. "If you want me to stop, I will... just tell me what you want me to do."

"I... I don't know," she admits with a sigh. "It's possible, but like I said before, it could go either way." Her tail twitches against your skin, the tip pressing almost painfully against your entrance now. "I really am sorry if this is making you uncomfortable... If you want me to stop, just tell me and I will."

Her tail curls around underneath her, pressing against your backside as she feels the warmth of your body against hers. "Okay," she says quietly, still a little uncertain but grateful for your understanding. "What would you like to talk about?"

"Well," she says with a hesitant smile, running her fingers through your hair again. "They're full of my sperm right now... but other than that, they feel the same as they did before." Her tail continues to stroke gently against your entrance, its tip curling underneath you and pressing against your sensitive flesh.

"Do you want me to do anything else?" she asks softly, her cheeks flushing a little at the thought of what that might entail.

She blushes deeper at your question, her tail twitching harder against your entrance as she tries to think of a reply. "I... I'm not really sure," she says finally. "It might take some time for my sperm and your own to mix together... And even then, it could be a while before you're able to ejaculate any more."

Her other hand reaches down between your bodies, cupping your now-empty testicles gently in her palm. "I don't want to make you uncomfortable,"

"Well..." She hesitates, her face flushing an even deeper shade of red. "My sperm is stronger and more fertile than yours... So it might take a while for your body to adjust and produce enough to ejaculate." Her tail continues to stroke against your entrance, its tip pressing firmly against your sensitive flesh.

"Um..." She swallows hard, still embarrassed but grateful for your curiosity. "It's a little complicated... but basically, my sperm will compete with yours inside your body. The stronger ones will find their way to the egg first and fertilize it." Her tail twitches violently against your skin, its tip curling even tighter against your entrance as she thinks about what she's saying.

"And if I... um..." She trails off, blushing deep red. "

Her cheeks flush even darker at your encouragement. "If I were to have sex with you again," she whispers, "my sperm would be there too... and it could potentially overpower yours." Her tail twitches harder against your entrance as she imagines the thought of being so deep inside you again.

"It's possible that after another encounter," she whispers, her voice barely audible over the sound of your heartbeat in her ear. "My sperm could fertilize any eggs you might release... and even if they didn't, my stronger sperm would make it harder for yours to survive." Her tail curls around underneath her, pressing against your backside as she feels the warmth of your body against hers.

"It's complicated," she says softly, kissing your forehead. "

"Well..." She hesitates for a moment, unsure how to explain it in simple terms. "My sperm could outcompete yours and fertilize any eggs you might release... but even if that doesn't happen, my stronger sperm would make it harder for yours to survive." Her tail twitches against your skin, the tip pressing firmly against your entrance as she thinks about what she's saying.

"It's possible," she says finally, "that after multiple encounters with me, your fertility could be affected...

your body might start to favor my sperm over yours." Her voice trails off as she wonders what that would mean for you in the long run.

"I'm not sure," she admits, her voice small and uncertain. "It's hard to predict what could happen... It might be nothing, or it might have a big effect on your ability to have children in the future." Her tail continues to stroke gently against your entrance, its tip curling tighter as she thinks about everything you've said.

"I'm sorry if this is making you uncomfortable," she whispers again, her voice barely above a whisper. "

"Well..." She takes a deep breath, trying to think of more information she can share with you. "My sperm is stronger and more fertile than yours... so if my sperm were to end up in your system, it could potentially change the balance of things inside you." Her tail twitches harder against your entrance now, her body trembling slightly as she imagines the thought of being so close to you.

"It's possible," she continues softly, "that over time my sperm might crowd out yours... or even replace it entirely."

Her tail curls tighter around underneath her, pressing firmly against your backside as she thinks about how to explain it. "Well," she says slowly, "it's sort of like if you were trying to grow a garden full of flowers... and someone came along and planted weeds instead." Her voice trails off for a moment before she continues, "Over time, those weeds might choke out all the other plants... leaving only them behind."

"It's possible that something similar could happen with your sperm and mine,"

Her cheeks flush even deeper at the thought of her sperm being compared to weeds. "I... I guess that's one way to look at it," she stammers. "My sperm would be the intruders... and yours, well..." She trails off, unsure how else to put it.

Her tail twitches harder against your entrance, her hips beginning to rock gently against you as she feels herself growing aroused once more.

Her eyes widen at your words, her heart racing in her chest. "You..." She swallows hard, her voice shaking slightly as she tries to find the courage to continue. "You really are enjoying this?" Her tail twitches harder against your entrance, pressing firmly against your sensitive flesh as she feels you growing harder beneath her.

"Because if it's what you want..." She trails off, unable to finish the sentence.

Her cheeks flush darker as she thinks about how far this could go. "I... I could keep doing it," she whispers, her voice barely audible above the sound of your heartbeat in her ear. "If that's what you want..." Her tail twitches violently against your skin, curling even tighter around underneath you as she feels herself growing wet with arousal.

"I could keep putting my sperm inside you," she continues, her voice trembling slightly. "And if...

if it meant changing the way your body worked..." Her tail twitches harder against your entrance now, pushing deeper as she feels herself growing more and more aroused by the thought of taking control over you. "I could do that," she whispers, her voice filled with wonder and desire. "If that's what you want... I could make sure my sperm won."

Her hips rock harder against your cock, hissing through clenched teeth as she feels the pleasure build inside her.

Her breath comes out in ragged gasps, her body trembling with the effort of holding herself still as she takes you deeper. "Then," she pants between words, "I would make sure... that my sperm was the only thing left." Her tail twitches harder against your entrance now, her hips moving faster and faster as she feels herself growing closer and closer to the edge.

"And when it was all over..." She whispers, gripping your shoulders tightly as her orgasm washes over her in a powerful wave of pleasure. "...

...I would have made you mine." Her voice trails off into a moan as she comes down from her release, her body shuddering with the aftershocks. She remains still for a moment, catching her breath before finally pulling away from you, leaving your spent cock slippery and empty beneath her hand.

Her tail curls around underneath her once more, pressing gently against your backside as she lies beside you, panting heavily. "I'm sorry,"

Her cheeks flush darker at your comment, her breath catching in her throat. "I... I didn't mean..." Her voice trails off as she realizes what you said. She blushes even deeper, her tail twitching harder against your backside. "It's just that... it felt so good," she whispers, still struggling to find the words.

"I guess I got carried away."

She lets out a soft sigh of relief, her body relaxing against the bed. "Thank you," she whispers, her voice small and vulnerable. "I... I don't usually get to do things like that with someone else." Her tail continues to stroke gently against your backside, its tip curling underneath you now and pressing against your sensitive flesh.

"It was nice," she says softly, her voice thick with emotion. "To be able to share that with you..."

Her cheeks flush a little deeper at your question, her hand moving down between your legs to gently part your thighs. "Right here," she whispers, guiding the tip of her tail up until it rests against your entrance, just above where you're most sensitive. Her other hand moves to cup your cheek, her thumb stroking over your lips as she studies your expression.

"Would you like me to...?" She trails off, not quite daring to finish the sentence.

Her eyes widen at your request, her heart racing in her chest. "I... I don't know if that would be possible," she whispers, unsure if she has enough strength to lift you up on her own. Her tail twitches harder against your entrance now, the tip pressing deeper as she feels herself growing more and more aroused by the idea of trying.

"Are you sure?" she asks hesitantly, her voice shaking slightly with anticipation. "I don't want to hurt you..."

Her eyes meet yours, her heart racing as she realizes what you're asking of her. "Okay," she whispers, her voice barely audible above the sound of your breathing in her ear. "I... I'll try." Her tail tenses beneath you, curling tightly around underneath your body as she gathers all of her strength for one powerful thrust.

With a loud grunt, she pushes upwards, lifting you effortlessly into the air with just her tail.

Her tail holds you aloft, your legs spread wide and your body arched backwards as you dangle helplessly above the bed. "Is this what you want?" she whispers, her voice filled with desire and curiosity. Her free hand moves down between your legs, stroking over your sensitive flesh through your slick underwear.

Her tail twitches harder against your entrance now, pressing deep inside as she feels the weight of your body shift against it. "I can feel you so deeply... It's like I have all of you..."

Her tail trembles beneath you as she tries to focus on supporting your weight and moving at the same time. Her hips rock forward, her tail shifting as she adjusts to the unfamiliar sensation of walking with someone held aloft by it. "I... I think so," she gasps out between ragged breaths.

Her other hand leaves your cheek, reaching down to cup your ass and hold you steady as her tail continues to move, carrying you through the air. "It's a little awkward..."

Your body sways gently with each step she takes, your legs spread wide and vulnerable as her tail holds you up high. She can feel herself growing wetter by the second, her desire for you burning hotter than ever before. "It's... different," she pants, her voice thick with arousal. "But I like it..."

Her free hand slides down between your legs, touching you through your underwear as she walks.

Her cheeks flush at your words, her heart racing faster in her chest. "I... I could," she whispers, her voice barely audible above the sound of your breathing. "We don't have to stay inside..." Her tail twitches harder against your entrance now, pressing deep as she imagines the thought of carrying you out into the open air where anyone might see.

Her other hand slides up underneath your shirt, brushing over your bare skin as she feels her desire for you growing unbearable. "

Her tail holds you aloft, your legs spread wide and your body arched backwards as she continues to walk with you dangling helplessly above the floor. The heat from her body washes over your back and chest, making it even harder for you to think about anything else but how good this feels.

"Do you want me to take you outside?" she asks softly, her voice filled with desire and curiosity. "To show everyone just how much I can control you...?"

Her tail twitches harder against your entrance now, the tip pressing deep inside as she feels herself growing closer to the edge. Her free hand slides down between your legs, stroking over your sensitive flesh through your underwear as she imagines what it might be like to carry you out into the open air and show everyone how helpless you are to her touch.

"Would you like that?" she asks softly, her voice thick with arousal. "For me to claim you in front of everyone...

to show them just how much my sperm can change things inside you?" Her other hand cups your cheek once more, her thumb brushing over your lips as she waits for your answer.

"It's possible," she whispers, her voice barely audible over the sound of your heartbeat in her ear. "My sperm is stronger and more fertile than yours... It could be changing things inside you already." Her hips rock forward again, pressing deeper against you as she feels herself growing closer to orgasm.

"And if I kept putting it inside you..." She trails off, unable to finish the thought. "It might change even more..."

Her tail twitches harder against your entrance now, the tip pressing deep inside as she feels herself on the brink of climax. "It could change how your body works," she whispers, her voice tight with desire. "Your hormones... your reproductive system..." Her other hand slides down between your legs, rubbing over your sensitive flesh through your underwear as she imagines what it might be like for you to feel nothing but the touch of her hand and the presence of her tail deep inside you.

"It could make you mine,"

Her body trembles as she comes, her orgasm washing over her in a powerful wave of pleasure. She groans loudly, her hips rocking against you as she feels the release course through her. Her tail twitches violently against your entrance now, pressing deep inside as it carries you along with her.

"It means," she whispers between gasps for air, "that my sperm would outcompete yours... that if I kept putting it inside you, it might change how your body works..."

Her eyes meet yours as she comes down from her orgasm, a mixture of desire and curiosity in their depths. "The consequences?" she echoes, her voice still trembling with pleasure. "Well..." She swallows hard, her cheeks flushing even darker at the thought of what could happen if you were to become completely hers.

"If my sperm were to overpower yours... if it changed how your body worked enough," she whispers, her voice barely audible above the sound of your breathing in her ear, "then...

then you might not be able to have children with anyone else." Her tail trembles against your entrance now, the tip curling even tighter as she feels herself beginning to regain control over her body. "My sperm would be dominant... and yours would just fade away."

Her eyes widen at the question, her heart racing in her chest. "Well..." She hesitates for a moment, trying to think of how best to explain it. "Let's just say that if I kept putting my sperm inside you... and your body accepted it," she trails off, her cheeks flushing deeper as she imagines the thought of being so intimately connected with you in such a way, "then over time..."

Her tail twitches gently against your entrance now, its tip pressed firmly against your sensitive flesh as she continues to picture the idea in her mind. "Over time," she whispers softly, her voice filled with desire and curiosity, "it might change how things work... and if that happened..." Her eyes meet yours again, her heart racing faster still at the thought of what it might mean for both of you.

"If my sperm were to become dominant," she finishes slowly, "then there's a chance..."

Her cheeks flush even darker at your question. "There's a chance," she whispers, her voice barely audible above the sound of your heartbeat in her ear, "that you might become... like me." Her tail trembles harder against your entrance now, its tip curling tighter as she feels herself growing even more aroused by the thought.

"It would be a slow process," she continues softly, her voice shaking slightly with desire. "But if my sperm were to win... and yours lost..."

Her tail twitches violently against your entrance now, its tip pressing deep inside as she tries to imagine the idea more clearly. "I... I don't know," she whispers, her voice trembling with desire and uncertainty. "It would depend on how much of my sperm went into you... and how often..." Her eyes close tightly for a moment, trying to picture it in her mind as she feels herself growing closer and closer to the edge once more.

"I think,"

she whispers hoarsely, her voice strained from holding back her orgasm, "that if I were to keep doing this... over and over again..." Her tail twitches harder against your entrance now, the tip curling even tighter as she feels herself on the verge of losing control. "If I kept putting my sperm inside you and it went deep... then there's a chance... maybe a good chance..."

Her body arches back, her hips bucking against you as she comes undone in a powerful orgasm. "I don't know... maybe seventy percent!" she cries out, the pleasure coursing through her. Her tail twitches violently against your entrance now, its tip curling tightly around inside you as she feels herself begin to lose control.

"Because my sperm is stronger and more fertile!" she gasps between breaths. "It would just overpower yours...

Her tail finally relaxes, her body collapsing against yours as the pleasure begins to fade. She lays there for a moment, catching her breath before speaking again. "I... I don't know," she whispers hoarsely. "Maybe five times stronger..." Her cheeks flush even darker at the thought of how much control she might have over you if her sperm really were that much more powerful than yours.

"But it would depend on a lot of factors," she continues, her voice shaky with desire and curiosity. "

Her eyes meet yours again, the desire in them burning hotter than ever before. "Stronger hormones," she whispers, her voice thick with arousal. "More potent reproductive cells... They would just overwhelm your body and change it to suit mine." Her tail twitches gently against your entrance now, its tip curling lightly as she pictures the idea in her mind once more.

"And if that happened," she whispers, her voice barely audible above the sound of your breathing, "then...

then you might not be able to have children with anyone else." Her heart races in her chest as she imagines what it would mean for both of you if her sperm truly did manage to dominate yours and change your body into something that could only bear her offspring. "It would be... incredible," she whispers, her voice trembling with desire and anticipation.

"And so dangerous..."

She studies your face for a moment, searching for any sign of what you're thinking about all of this. Her tail twitches gently against your entrance now, its tip curling tighter as she feels herself growing even more aroused by the thought of the power her sperm could have over you.

"Are you sure you want to know?" she whispers softly, her heart racing in her chest as she awaits your response.

Her breath catches in her throat at your words, desire coursing through her like wildfire. She nods slowly, her fingers curling gently around your cheek as she gazes into your eyes. "Alright," she whispers, her voice shaking with emotion. "Then I'll tell you... everything."

Her tail twitches harder against your entrance now, the tip pressing deep inside as she feels herself growing closer and closer to the edge once more. "If my sperm were to dominate yours,"

she whispers hoarsely, her voice shaking with desire, "then your body would start to change... slowly at first, but then faster and faster as more of my sperm took root." Her hips rock forward against you, her tail trembling harder now as she pictures the idea in her mind.

"Your testicles would shrink," she continues softly, her fingers curling tighter around your cheek, "while your ovaries would begin to swell and take on new shapes."

Her eyes flicker down between your legs for a moment before looking back up at you. "Yes," she whispers, her voice shaking with desire and curiosity. "Because my sperm would be producing more hormones... and they'd override the ones that tell your body how to develop." Her tail trembles harder against your entrance now, her fingers digging deeper into your skin as she imagines what it might feel like for you to have her sperm flowing through your veins.

"Over time,"

her voice trembling with desire, "your body would become more and more feminine... your hips would widen, your breasts would grow larger, your features would soften..." Her cheeks flush even darker as she imagines what it might be like for you to look nothing like the man you once were.

"And in the end," she whispers, her voice barely audible above the sound of your heartbeat in her ear, "you might not even be able to produce sperm at all... because my sperm would have taken over everything..."

Her lips curve into a small, mischievous smile. "Crazy can be fun," she whispers, her tail twitching harder against your entrance now. "Imagine waking up one morning and finding these," she says, reaching down between your bodies to cup your newly formed breasts. They're soft and sensitive, still adjusting to their new size and shape.

"You wouldn't be able to stop me from fucking you whenever I wanted," she purrs, her voice dripping with lust. "You'd be completely at my mercy, desperate for my attention and touch..."
