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
