"Oh..." Joanna says, a note of surprise and desire in her voice. "Do you really want that?" She asks, her gaze flicking to where our hands are entwined before meeting mine again. Her skin feels warm and soft against my lips as I kiss her more deeply, slipping my tongue between her teeth to explore the depths of her mouth.

With a moan, she arches into me, pressing her body closer. "Oh yes..." she breathes out, her fingers digging into my arm. "I want that too."

Her words send shivers down my spine as I feel a surge of desire welling up inside me. Reaching out, I gently stroke the length of her arm before cupping her breast through her dress, feeling her hard nipple peak under my touch. She moans softly into my ear, her hips moving against mine in rhythm with my hand.

"You know you can have it all," she whispers, her breath hot on my neck. "Just tell me what you want...and I'll give it to you."

"Oh god..." Her words are cut off by another wave of pleasure washing over her as she orgasms, her body shuddering beneath yours. You continue to thrust into her, feeling your own release building as you watch her face contort in ecstasy.

Finally, you groan and empty yourself deep inside her, spurting hot cum with each powerful stroke. She moans loudly as she feels your seed filling her up, her body quivering from the intense sensation.

When you finally pull out of her, spent and satisfied, she rolls onto her side and curls into a ball, catching her breath. You lie down next to her, running your fingers through her sweat-damp hair as you both try to regain control over your racing hearts.

"Wow," she whispers after a moment, looking up at you with a satisfied smile. "That was... intense."

You grin back at her and kiss her gently on the forehead. "Yeah. It sure was."

You moan softly as you feel him beneath your fingers...it's been so long since anyone has touched you like this and it feels incredible. You reach around behind him and begin to unbutton his swim trunks, freeing his hard cock from its confinement. He lets out a shuddering breath at the contact as he continues searching through your clothes, oblivious to what you're doing.

As he begins to move around, searching through your clothes, you guide his cock to your wet pussy, slowly lowering him onto your aching clit. He lets out a low groan as he feels you surrounding him, and without warning, begins thrusting wildly into you. His movements are rough but passionate, driving you both towards the brink of ecstasy. You moan his name as the sensations build inside you, wanting nothing more than to feel him cum deep within your body.

Hmmm...I think I see an opportunity now. There are some empty cabanas nearby that no one seems to be using at the moment. If we could manage to sneak away there for a few minutes, maybe we'd have enough privacy to take things further. I glance over at you, wondering if you've noticed too

With a sly smile, I stand up from the lounger and motion for you to follow me over to one of the empty cabanas nearby. Once we're inside, I shut the door behind us, sealing us off from the rest of the party. My heart races with anticipation as I lean in close to you, my lips brushing against your ear. "So...what do you think we should do now?"

Oh no! Quick, cover yourself up before she sees everything. I quickly turn around and block my naked body with my arms, hoping she doesn't notice anything

"Sis! What are you doing here? We were just taking a shower together, that's all." I smile innocently at her while keeping my back towards her

"Oh... Okay then. Well, I just wanted to borrow some sunscreen from mom's bag. Don't let me interrupt you two..." She blushes slightly and seems a bit flustered before turning around and exiting the bathroom "Everything is fine, son... Just make sure not to tell anyone about this okay?" I nudge your side with my elbow and give you a wink as I turn back around, giving you a sultry look over my shoulder
