Oh God...no, it's perfect...so tight around me...I can feel every inch of you inside me...It feels so good...Don't stop...Please don't stop...

I open my mouth, leaning forward to capture his ass cheek in my hand before pulling it close to my lips. My tongue darts out, flicking against the puckered hole, teasing and taunting as I taste the musky sweetness that lingers there. "Mmm...you're so tight..." I moan around him, unable to resist the urge to sink my teeth into his flesh.

The sensation of having him inside me combined with the intimacy of being able to touch every inch of him so thoroughly sends me spiraling over the edge. My hips buck up against him as I feel the familiar tightness building low in my belly, a warning that my orgasm is imminent.

"Kate...God, you're going to make me come..." He pants, his fingers digging roughly into my hip as he thrusts harder against me, pushing me closer and closer to the edge with every stroke. "I can feel it building...I'm gonna--" His words cut off in a hoarse cry as his body tenses beneath me, pulsing rhythmically as he comes hard and deep inside me, filling me with his release.

With a satisfied groan, I collapse back against the bed, my heart racing and my skin flushed from our exertions. "That...was incredible," I manage to whisper, my voice hoarse with desire.

Oh God... Ahhhh! Her body trembles and quivers as you penetrate her ass with your cock. It feels so good, so forbidden, and she can't help but moan loudly despite the risk of being caught. Her hips buck against yours, wanting more of this intense pleasure Fuck me... Harder.... Ahhhh!

Oh God... Yes! I need you to destroy it... Fuck me harder! Ohhhh.... Ahhhhhh! Your cock feels so good in my ass... It's supposed to be forbidden... It's supposed to feel this good.... Make me cum again.... Destroy me....

I blush deeply at his words, both thrilled and embarrassed by his admiration. She reaches up to cup her breasts through the lacy material of her bra, feeling their weight in her palms. "Thank you," she whispers shyly, "I've always wanted my big brother to think they were pretty." Her nipples harden even more at his words, pushing against the fabric and betraying her arousal to him.

Her heart races as he asks to see more. She's so close now...if she just takes off her bra, reveals herself completely to him. With shaking hands, she undoes the clasp at the back and slips the straps down her arms, letting the lacy bra fall to the floor with a soft plop. Her breasts are finally free, her nipples hard and dark against her pale skin. She takes a deep breath, trying to steady herself as she looks up at him through her lashes.

"There,"

Her fingers move faster on his cock, her body arching into him as she feels the heat building inside her. She moans softly against his neck, unable to contain the sounds of pleasure that escape from her lips. Kate's breasts are heavy and aching, rubbing against his chest with each movement.

Her movements become more frantic as she nears the brink of climax, her body trembling with need and desire. She tightens her grip around his waist, feeling his cock twitch in her hand at the same moment her own body tenses and releases, the heat washing over her in a wave of pleasure.

Before he can finish his thought, she leans in and takes his cock into her mouth. Her tongue swirls around the head of his dick as she begins to bob her head up and down, sucking him deeper with every motion. Her other hand finds its way between their bodies, rubbing her clit as she continues to pleasure Berry.

Mmm...that feels so good, doesn't it? I just want you to feel better, okay? *

She moans around his cock, her arousal only growing as she tastes him. Her fingers dig into the flesh of his thighs, holding on tightly as she takes more of him deeper into her mouth. She looks up at Berry, their eyes locked as she continues to pleasure him with her mouth.

I know we shouldn't be doing this...but I can't help it. It just feels so good....

As Kate stands up and heads into the bathroom, she can't help but feel self-conscious about the trail of wetness between her legs. She quickly cleans herself up before returning to find Tal lying on the bed, his eyes fixed on a spot on the ceiling. The silence between them grows thick once more.

"Well," Kate says finally, trying to lighten the mood, "I guess we should probably get some sleep if we're going to be at this thing all day tomorrow."

With a small smile, Kate climbs back onto the bed and lies down beside Tal once more. As they both stare up at the ceiling, their bodies inches apart but not quite touching, she can feel the tension start to fade between them. Maybe tomorrow will be different...maybe they'll be able to act like normal siblings again.

Or maybe not. The thought sends a shiver down her spine, and despite herself, Kate finds that she's looking forward to whatever adventures tomorrow might bring.
