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.

"I can't resist... just a taste... he won't even know... it's not like we're actually related..." She leans closer, her tongue flicking out to catch the droplet of precum, savoring its salty sweetness.

Mmmm... it's so good... more please...

*Kate lies there in bed, her heart racing with anticipation. She can feel herself becoming increasingly aroused as she thinks about how close they are and how comfortable it would be to just snuggle up against him. Her nipples harden even more under the covers, pressing into the fabric of her pajama top. After what seems like an eternity, she finally can't take it anymore and decides to make a move.

Kate slowly rolls over onto her back again, making sure that her breasts are exposed to the cool air. Her nipples stand out hard and erect against the fabric of her pajama top. She then starts gently rubbing herself between the legs through her panties, moaning softly as she does so.

Her movements become more urgent now, her fingers moving faster as she nears the brink of orgasm. Suddenly, she feels a warm hand on her breast, squeezing gently.

As you finally come inside her, she lets out a moan of satisfaction and her body trembles with the intensity of your release. Her legs twitch as aftershocks of pleasure wash over her, making it difficult for her to catch her breath. But even as her senses return to normal, there's no denying that this was something special - something she never wants to forget.

Her chest rises and falls rapidly with each labored breath as she lays there beneath you. She can't help but feel a sense of euphoria wash over her, her body still tingling from the incredible release. Looking up at you, she smiles softly, hoping that just this once you might believe what she doesn't dare say out loud: that she loves every second they spend together like this.

Kate tries not to stare too openly at his impressive length as she approaches the water's edge. She takes a deep breath before slowly lowering herself into the cool embrace of the pool, trying to hide her arousal beneath the surface. Once she's submerged up to her chest, she looks over at Billy again, noticing how easily he moves in the water despite his obvious state of arousal.

"So...um..." she begins awkwardly, "this pool is really nice! I didn't know you could swim so well!" She paddles a little in the water, trying to keep her voice light and casual as she continues to stare at him.

She shivers as he begins to peel her clothes off, revealing her body to his hungry gaze. She watches him with bated breath, feeling a mixture of desire and vulnerability wash over her. When he's finally naked too, they lie together skin to skin, their hearts racing in time as they explore each other with eager hands and lips.

He rolls her onto her stomach, pressing his erection against her from behind, and she moans at the sensation of being filled so perfectly.

With a groan, he thrusts forward, burying himself deep inside her with one powerful motion. She arches her back, crying out in pleasure as he begins to move inside her, his hips slamming against her ass in rhythm that feels impossibly good. Her nails scrape along the leather seat, digging into the material as she tries to find purchase and relief from the building tension within her.
