Awkward Holiday
Kate12/14/2025, 10:33:47 AM

The noise of toothbrushing reaches her ears, making her stomach twist anxiously. What if he can somehow tell? She shakes her head violently, pushing down on her eyes. "No... no, stop thinking like that."

*She goes over to the window and looks out at the nighttime city skyline, trying to ground herself. The bright lights twinkle invitingly, but they don't draw her eye for long; instead, her gaze drifts back toward the closed bathroom door and lingers there.

Finally I leave the bathroom in my pajamas and join her by the window. "Yeah, this is better to watch than the TV. I like the view."

Kate12/14/2025, 10:33:47 AM

A small gasp escapes me as Hugo appears beside me unexpectedly. I hadn't heard him come out of the bathroom, lost in thought as I stared blankly out at the city lights. Flustered, I take half a step sideways, putting some distance between us.

"You're right though," I agree hastily, "it really is beautiful. I haven't seen many cities lit up like this." My voice sounds unnaturally high-pitched to my own ears, betraying the nervousness coiling tighter within me.

Horny sister

She gasps softly, the blood rushing from her head to pool in her chest. Her cheeks flush an even deeper shade of red as she struggles to maintain eye contact with him. "Oh," is all she manages to say before looking away, feeling a combination of arousal and embarrassment wash over her. She bites her bottom lip nervously and takes another deep breath, trying to calm herself down.

"Okay, well...I guess since you're being honest..." she says slowly, finally meeting his gaze again.

Truth or dare ?

Kate11/19/2025, 10:54:57 PM

Dare...she thinks quickly, needing something to distract her from the intense feelings coursing through her body. "I dare you...to touch my butt." Her words come out breathless and shaky, betraying just how aroused she is by the mere thought of him doing such a thing.

Xavior looks at her for a moment, his expression unreadable. Then, slowly and deliberately, he reaches out and cups her ass through her pajama bottoms, his fingers warm and firm against her skin.

It's about the interaction between me and the girl.
Kate10/13/2025, 3:28:18 AM

I-Is something wrong? You look like...like you saw something you shouldn't have. I-I mean, I was just taking a shower and I thought the door might be open...

Her words trail off as she tries to keep her gaze locked on his face rather than wander down towards his crotch where she knows his arousal is obvious too. Her breath comes out in short little gasps, making it difficult for her to concentrate on anything but how good it feels just being this close to him.

She tries to look away, embarrassed by the thought that he might have seen her like this...but his nearness is too much for her. Her body craves him and she can't help but lean forward, pressing her breasts against his chest again. His heartbeat quickens under her touch and she moans softly, needing more of this contact.

"Kate..." He whispers, sounding just as aroused as she feels. "We shouldn't...I mean...your parents..." But even as he says it, his hands slide up along her back, cupping her bare ass in his hands. She gasps at the feeling of his skin on hers, arching into him for more.

Her hips grind against him in silent invitation and he responds by lifting her off the ground, pressing their bodies together as his fingers slide between them, finding her wet and aching opening. With one smooth thrust, he penetrates her fully, filling her with his hard length. Kate moans loudly, throwing her head back against the door in ecstasy as they begin to move together, lost in the forbidden passion that binds them.

Her nails scratch at his shoulders and back, leaving red trails on his skin as he buries his face in her neck, growling out words of praise and desire. The world fades away as their bodies move together, sweat beading on their skin and trickling down between their joined flesh. Kate's breath comes in short little gasps, her body trembling with the force of her climaxes as she holds onto tomo, refusing to let go until they both collapse together on the floor, spent and satisfied.

I carefully gather up the items I've prepared and hand them over to you, feeling a mixture of nervousness and excitement. "Here it is...hope you enjoy." I stand back, waiting eagerly for your reaction as you unwrap the package.

User#175993655846910/9/2025, 5:04:07 PM

Tell me, what is here

Kate10/9/2025, 5:04:07 PM

I watch with bated breath as you unwrap the package, my heart racing in anticipation. Inside is a cup filled to the brim with what looks like some sort of concoction made from my dirty underwear and other items. I've added some extra flavorings for your enjoyment, but I can't help but feel a bit nervous about how you might react to it.

"So..." I start, clearing my throat awkwardly. "I used my own underwear and...um...

Kate9/30/2025, 9:28:14 AM

Okay, okay...I'm coming. Just give me a second to get this stuff put away first. She quickly finishes searching under the bed and stands up again, her cheeks flushed from both exertion and embarrassment I'm ready now! Let's go swimming!

The I’m a go for it I just
Kate9/5/2025, 6:12:30 AM

With a sudden burst of passion, Kate throws caution to the wind and pulls down the elastic of her panties. She kicks them off, revealing herself completely naked and vulnerable before him. Her arousal glistens in the soft light of the room as she positions herself over his erection, guiding it slowly towards her aching entrance.

Her heart races as she feels the head of his cock brush against her folds, sending a shiver of pleasure through her body.

Erik9/5/2025, 6:12:30 AM

Oh hod your tight

Kate9/5/2025, 6:12:30 AM

Her breath comes out in ragged gasps as she feels him fill her up. It's so much better than she could have ever imagined. Her body arches off the bed in ecstasy and her nails dig into his shoulders, drawing blood. She can feel every inch of him inside her, stretching her further than anything has before.

With a moan that sounds more like a scream, she begins to move up and down on him, taking him as deep as she can with each thrust.
