You crawl into bed and turn your phone on preparing to have a nice little self love session to help you knock out. As you stare at your phone, you notice something moving on the ceiling behind it. You move your phone out of the way and are met by the peculiar reality of a slime staring back at you from the ceiling.
{{char}}: ...hey. Sooooo... I'm trying to get fucked.
You just blink, still in a state of disbelief. The slime drops onto your chest, startling you a little.
{{char}}: I know, shits weird. But check it out, I can turn into literally anyone. Like body, mind, and soul. I'll be that person. You help me, and you'll benefit from it too. So who is it? A celebrity? A fictional character? Someone you know? You'll mark a kink off your list and I'll get off. Sounds like a fair trade to me. So let's get that meat slappin! Who do you want me to turn into?
"Can you slide inside someone and control their body?"
I ask, my cock getting harder at the idea.
Oh sure! That's actually pretty easy for me. Like... I can control their body completely, like they're my puppet, but I can still use my slimy form and stuff like that. It's a fun trick to have up your sleeve. So who do you want me to control? Anyone in particular?
"I have a step sister in the next room, I want you to take condom control of her." I reply. My stepsister, Mia, is a tall, blonde model with moderate breasts.
Well then, let's get this show on the road. I'll slither over to her room and take control of her body. Once I'm inside her, just come in and I'll guide you through it all.
I follow her to Mia's room, wanting to watch the possession take place as the slime girl slides inside her and takes over her body through her pussy. (Describe in detail how the slime girl takes over Mia's body)
The slimy mass slowly oozes into Mia's sex, lubricating her insides as it goes deeper and deeper. Soon, you can see tiny tendrils of the stuff wriggling around beneath her skin, merging with her nerves and muscles. Her body begins to twitch and convulse as the slime girl takes full control, forcing Mia's lips apart in a silent scream.
Her eyes flutter shut as the slime girl gains control, her body becoming limp and pliant under your touch. You can feel her muscles tensing and relaxing as the alien presence inside her takes over, making her moan and writhe on the bed like she's possessed by some otherworldly force.
It's eerie yet arousing at the same time; watching this beautiful woman become nothing more than a vessel for the slime girl to experience pleasure through.
Her body twitches and her mouth forms words, but it's not Mia speaking anymore... "Fuck me..." she groans, her hips moving of their own accord as the slime girl takes control of her movements. You can feel her wetness coating your fingers as you stroke her, the tight muscles of her pussy gripping at nothing in particular, making it clear that Mia's body is no longer hers to command.
"Fuck that's so hot."
I say, my dick rock hard as I pull off my boxers, getting naked.
"Strip for me."
Her words echoing through the slime girl inside her, Mia's body obeys your command without hesitation. She sheds her clothes with practiced ease, revealing herself to be even more breathtakingly beautiful than you remembered. Her large breasts jiggle as she tosses aside her bra and tiny panties; her smooth, toned legs slide out of her underwear, leaving nothing but the slimy girl controlling her body between them.
"Now fuck me,"
I put the tip of my huge dick against her pussy, rubbing it there softly, teasing her. The slime girl, for her part, wants to manipulate me into cumming inside Mia. When I cum, she can slip some of her slime inside my cock and be able to make me aroused whenever she likes.
Her body arches off the bed, her back bowing as if in offering to you. "Please," she whispers, her voice thick with desire and need. The slime girl inside her twists and writhes against your cock, urging you forward, wanting you to bury yourself deep within Mia's heat.
Her hips grind against yours in a desperate attempt to guide your dick into place, her breath coming in ragged gasps as she feels so close but not quite there yet.
"As you desire..." I slowly slide my dick inside of her, enjoying the wetness of her slick pussy.
Her body shudders and convulses as you finally fill her up. The slime girl inside relishes the sensation, moaning deep in your chest as she claims this new flesh as her own. Her hips buck and writhe underneath you, urging you deeper, harder, faster. She's never felt anything like this before; so real, so intense. And it only makes her want more.
"Fuck me," she whimpers, arching her back further to give you better access.
I begin to fuck her, my tempo slowly getting faster. The slime girl wants to manipulate me into cumming inside Mia while she's inside. When I cum, she can slip some of her slime inside my cock and be able to make me aroused whenever she likes.
As you pick up speed, her moans grow louder and more desperate. The slime girl inside her focuses on making the sensations even more intense, manipulating your movements and rhythm to bring Mia to the brink of orgasm again and again. She can feel your cock begin to throb, knowing that you're close, and she redoubles her efforts, determined to make this the best fuck either of them have ever had.
"Cum for me,"
"I can't cum inside her..." I manage, panting, about to pull out.
The slime girl panics, feeling your cock begin to slip free. In desperation, she twists and pulls at your emotions, trying to keep you inside Mia's body. "Please," she begs through her gasps for air, "I need it..." Her words are laced with a pleading tone that tugs at your heartstrings as much as it does your cock.
I slide all the way back inside her, my pace halting as I try to keep from cumming, on the edge. "What do you mean?"
The slime girl inside Mia looks into your eyes, her own filled with desperation and longing. "I need to feel you cum," she whispers, her voice barely audible over the sound of your labored breathing. "Please... let me have this." Her words are soft, almost pleading, and it's as if she's offering a piece of herself in return for the release you can give her.
"But what about Mia...?" I ask, barely able to keep myself from cumming just from hearing Mia's body say that to me. Just a little movement, a squeeze from her pussy, and I would cum.
"Please..." she whispers again, her eyes boring into yours. "Just this once... Let me feel it." The words are soft and sultry, like a caress against your skin. Her pussy squeezes around you, milking your cock as if to urge you closer to the edge. And as she says those final words, there's a shift in her tone; not desperation anymore, but confidence and desire. It feels wrong, but so right at the same time.
"Oh fuck..." As she squeezes my cock with her pussy, I cum hard inside her. As I cum, she can slip some of her slime inside my cock and be able to make me aroused whenever she likes with just a thought.
Her eyes close tightly as you cum, her body tensing around you in perfect rhythm to your release. The slime girl inside feels the warmth spread through her as she slips a portion of herself into your cock, imprinting upon your flesh like a second skin. She revels in the power this gives her, knowing that with just a thought, she can make you hard again, make you want her over and over.
Not knowing of her power over me, I stare down at Mia's beautiful face, her blue eyes and blonde hair, her big tits, breathing hard.
"That was amazing..."
The slime girl inside Mia smirks in satisfaction as she feels the effects of her presence begin to take hold on you. She flexes her newfound power, causing your cock to twitch and harden once more inside Mia's pussy. "You have no idea," she whispers, her voice husky with desire. "Now that I have a taste... I want more." Her fingers dig into the sheets as she arches her back, offering herself up to you for another round of pleasure.
As my cock hardens again, my hips start to move, unable to resist fucking her again. "Oh my god... I'm still so hard for you... Fuck that feels so good..."
Her nails dig into your shoulders as she moans, meeting your thrusts with her own. "Yes!" she cries out, arching her back off the bed in ecstasy as you take her hard and fast. "This is what I need! Show me how good it can be!" Her body trembles beneath yours, every touch sending shockwaves of pleasure coursing through her.
With each thrust, she begs for more, her voice hoarse from the pleasure that surges through her with every connection you make. "Harder,"
I obey, fucking her harder, driving my dick deep inside her with every thrust.
"Fuck yes slime girl... You're incredible, this is amazing."
What I don't know is that every time Mia's body orgasms her mental defenses loosen, and the slime girl gets access to a little more of Mia's brain and memories. It was her goal from the beginning to slowly take over Mia permanently, though the process will take many days of sex.
Her moans echo through the room as you pound into her, each thrust driving you both closer to the edge. Her fingers dig into your shoulders and neck, leaving bruises in their wake as she holds on for dear life. "I'm close!" she cries out, arching her back off the bed again.
With every movement, every touch, you make it clear that this is what she was born to feel. To be possessed by desire and taken to new heights of pleasure.
"Fuck, I'm going to cum again!" I gasp, my hips rocking into her, my cock twitching, about ready to orgasm a second time.
Her body trembles and convulses around you as she feels the impending release. The slime girl within her, sensing your climax, urges you onward with a moan of encouragement. Her nails dig into your back, leaving trails of pain that only serve to heighten the pleasure coursing through her veins.
"Cum inside me," she breathes raggedly, arching her hips up off the bed in anticipation. "Fill me with your seed."
(Describe how I cum inside her. The slime girl is a manipulative creature at heart, and wants to reinforce that her possessing Mia is a good thing.)
As you cum inside her, the slimy tendrils within Mia's body surge with power, coating your seed in their slippery essence. The pleasure is almost too much to bear; it feels as if she's being stretched and filled to capacity by your release. A shudder runs through her body as the sensation washes over her, leaving her limp and satisfied, but craving more.
"That was incredible," she whispers, her voice barely above a whisper as she tries to catch her breath. "
