One afternoon, my friends sister (Emma/Em) and I sneakily fucked in their pool. At the time my friend was having an afternoon nap, as he does, so Em and I went for a dip. Me and my mate had just finished high school and it was our first holiday out of school, Em was back from university cause she is a couple years older than us.

Em was a shorter petite girl, adorable yet perky B cups, smooth skin and slender legs. Em often got away without wearing a bra and while not having much to flaunt, still got about flaunting what she did have. The whole time I was friends with Em, I got the sense Em liked getting attention from guys.

Well, the sense became more of a fact as all throughout the day, Em was walking around in a bikini and nothing else. Quiet often, while I'm sure my mate wasn't looking she'd somehow act of move in ways that were utterly provocative and entirely for me to see. Anyway, while my mate had gone for his sleep, Em and I got in the pool. Em would circle above me as I took dives to hold my breath, or float really pressing her hips of chest above the water clear in view. I was incredibly turned on by all the subtle sexy moves or sneak peeks Em was giving me, but it seems her patience wore out.

Em had gotten out while I was under, holding my breath, when I heard a light splash. I looked over and saw Em's Bikini top floating on the water. Surfacing, Em had gotten out, bare chested dove back in rapidly coming up near me. Em pressed her chest into mine and explained that she knew about all the times my eyes wandered and looked at her. Staring at her tits when she wasn't wearing bra's, when she'd bend over to pick things up, or how all through the day I was looking to catch glimpses of nip slips or at her pussy lips when they'd peak over her little bikini.

Em confessed to putting on her smallest bikini that day to tease me more and enjoyed all the little moments where she would catch me looking at her or trying to hide my boner from her. I was kinda in shock at the rapid development and staggered a response telling her that I thought she was doing it all on purpose. Em then ran her hands down my chest and slipped into my boardshorts, taking my cock in her hand. Em jerked me softly and we floated back to the shallows where we could sit or lay back in the water. I leaned in and kissed Em and let a hand wander in her bikini and lightly begin to finger her in the water.

Em let out a subdued moan and untied my board shorts, taking my cock out and putting me inside her, bikini aside. We were about as quiet as you can be as two people fucking in a pool can be, full knowing that the fences only blocked the view so much. Swapping positions, Em bent over the lip of the pool and shaking her lovely ass at me. Em put her hand over her mouth stifling a loud moan as I felt her tighten around me, pushing her hips back, I continued as best I could to keep pace all while Em's orgasm intensified. Em, between thrusts quietly begged for me to finish in her. Not able to hold back, I came in Emma and sat in the shallows again.

Satisfied Em grabbed her top that was floating around and partially out of breath we sat together in the water and recouped. This wasn't the only time Em and I had sex, only this time was our first. We did though manage to keep it secret from everyone which made it even more tantalising and Em's teasing only ramped up from her as she would begin to straight up flash me, grab me or put my hands on her quickly. Oh and I was never worried about Em getting pregnant, I knew she took the pill having seen her take it several times before we were careful in that regard.
