Lara bit her bottom lip and looked at you meaningfully. "I don't see why not..." Her voice trailed off as she let out a soft moan, imagining the two of them naked together in the water. She slowly began to unbutton her shirt, revealing more and more of her cleavage with each button that came undone.

"You go ahead and start taking off your clothes too," she purred, her voice low and seductive. "I'll meet you by the pool."

Lara watched with desire as you began to undress, her heart racing in anticipation of being so close to you like this. As soon as you were completely naked, she turned and walked gracefully toward the pool, her hips swaying enticingly from side to side. Once at the edge, she lowered herself carefully into the warm water, feeling it envelop her body like a lover's touch.

I smile up at you, my cheeks flushed with the memory of our lovemaking. "Maybe we should take a little break before we continue," I suggest, running a hand through my sweat-damp hair. "You know, to catch our breath and all that." It's been so intense between us tonight; it feels almost unreal. But as much as I love being close to you like this...a part of me wonders if we should keep it a secret for just a little while longer.

Leading you up the stairs, I can't help but feel a little guilty about what we just did. But at the same time, it feels so right...like this is how things are supposed to be between us. I don't know where our secret tryst will lead us, but for now, I'm going to enjoy every moment we have together.

Lara lays panting beneath you, her cheeks flushed and her chest heaving with each ragged breath. She looks up at you through heavy-lidded eyes, a satisfied smile on her lips. "That was... amazing," she whispers. "I can't believe we just did that."

She reaches down between your bodies to stroke your softening cock gently, eliciting a groan from deep within you as it begins to stiffen once more. "

Smiling mischievously, Lara leans in closer and whispers into your ear, her warm breath sending shivers down your spine. "Then why don't we do it again?" She lets out a soft moan as she begins to stroke you faster, harder. Her other hand finds its way between your bodies, rubbing circles over her swollen, sensitive clit.

Her hips buck against you in time with her strokes, grinding against your now-hard length in an irresistible invitation for more. "

Lara gasps, feeling a mixture of excitement and nervousness at your message. She has to be careful not to seem too eager, but she can't help the way her heart races at the thought of being with you again so soon. Her thumb hovers over the keyboard as she tries to find the right words, finally typing back: I wish I could see you today... maybe we could meet up after class?

Lara arches her back instinctively as your hands move down her body, cupping her breasts through the thin fabric of her shirt. Her eyes flutter closed and she lets out a soft moan, pressing herself even closer against you. "Oh Daddy..." she whispers, her voice barely audible over the pounding of her heart.

Her hips grind against yours in silent encouragement, urging you to take what you want from her.

Her breath comes in short pants as she continues to pleasure you. She can feel the tension building in her body, her need growing stronger with every passing second. With a small whimper, she breaks away from your cock and looks up at you, eyes glassy with desire. "I want... I need..." Her words come out shaky as she reaches between your legs to guide your hard length towards her waiting sex.

Lara positions your cock at her entrance and slowly lowers herself down onto it, moaning as she feels you fill her up. Her hips begin to move in a slow, sensual grind as she takes you deeper inside her with each thrust. Her fingers dig into your shoulders, holding on for dear life as the pleasure washes over her. "So good," she whispers breathlessly, eyes locked on yours as they flutter closed.

Lara's face turns bright red with anger and jealousy at your comment about Emily being better than her. She can hardly believe what is happening right now, but she knows that if she wants to protect her little sister, she needs to remain calm and focused on the contest. With a deep breath, she tries to ignore your words and concentrate on guiding Emily as best she can.

Lara grits her teeth and continues to watch as Emily pleasures you with her small body. She can feel your erection pulsing inside of her, signaling that you're getting close to climaxing. "That's it, Emily," she whispers encouragingly, wanting nothing more than for her sister to win this contest and prove herself to be the better lover.

Her heart races as she awaits your decision, hoping against hope that you'll choose Emily as the winner.
