After getting the beer, there wasn't anything else for me to do to prepare for the party. I decided that cooling off in the lake sounded like a really good idea at that point, so I grabbed a raft and dove off the end of the dock. Holly stood on the bank, visibly debating, until I asked her to bring me a beer (I even said please). She filled both our cups again and walked out to the end of the dock as I swam back to retrieve my frosty malt beverage.
When she bent down to hand me my beer, her loose oversized t-shirt fell open giving me a breathtaking view of delicious cleavage. I managed to avoid being caught ogling her as I took a big swig of beer. "Water's nice today," I informed her as I watched her over the rim of my cup. She took the (not-so-subtle) hint and grabbed the bottom of her t-shirt, pulling it up over her head. I, of course, used the obstruction to her view to admire the wonderfully hard body barely hidden by her bikini. How I longed for just a clear look at what was covered by those small triangles of fabric. But alas, I could only catch covert glimpses when she wasn't looking.
The party began soon after, when Holly's friend April arrived with her boyfriend and several others. Before long, we had a full-blown bash going on as the liquor flowed and inhibitions lowered. I wandered the party throughout the night, talking and drinking my way from group to group. Throughout the course of the night, however, my eyes kept drifting back to my cousin's lush body. She'd already been swimming and had thankfully decided not to put her t-shirt back on over the bikini. Her tanned skin glowed in the fire's light, and I could feel my cock start to stiffen in my shorts as I remembered the sight of her body in the shower.
I decided it was probably a good time to go jump in the lake to cool off and hide the large bulge in my shorts, so I grabbed a raft and took the plunge. The water was about as close to perfect as it could get, nice and cool on a hot summer night. I clambered up onto the raft and retrieved my beer from the dock, then began lazily kicking my way out a bit further into the water.
My relaxation was cut short by hands grabbing the raft and twisting it out from under me, dunking me (and my beer) into the water. I came back up spluttering, to see Samantha, one of Holly's friends, grinning wickedly just a foot away from me.
"You looked like you could use some cooling off," she giggled.
"Gee, thanks" I replied as we both reached for the raft at the same time, our bodies brushing together underwater. "You do realize that you dumped my beer in the water?"
"So what? The fish can get drunk too," she said as she (accidentally? yeah, right) pressed her body against mine as she tried to climb up on the raft.
"Actually, I was thinking about the alcohol abuse you committed," I stated as I wrestled with her for the raft, our nearly naked bodies writhed together.
"And what are you gonna do about it?" she laughed as we both tumbled off the raft, hopelessly entwined together, our faces only inches apart.
"Well, maybe I should do this," I said as I leaned forward and kissed her, wrapping my arm around her waist and drawing her body against mine. She complied by wrapping her legs around my waist and her arms around my neck, pushing her tongue into my mouth. I could feel the odd sensation of the barbell in her pierced tongue flicking against my own as my free hand (one was holding the raft to keep us both above-water) slid down her bare back to grab her ass, pulling her into my now-prominent bulge. One of her hands left my neck to work at the button on my cut-off jeans, upping the stakes of this little surprise interlude. I let my hand make the natural progression from her ass to her lycra-covered pussy, my fingers pushing aside the fabric to stroke her slit as she finally managed to pop open my fly and slid her hand inside to wrap her fingers around my aching cock, pulling it out and stroking it a few times.
We both managed to accidentally let our heads slip underwater during this fast foreplay, and the water closing over my head brought me to my senses enough to take a look up at the shore to the party that was still in full swing. Happily, we were far enough out in the dark to be outside the bonfire's light that none of the drunks up by the fire had a clue that we were about to fuck in the water just beyond their sight.
Samantha reached down between us and pulled her suit to the side as I worked my jean shorts down over my hips. I gasped as I felt my cock touch her opening for the first time, the sensitive spot just under the head of my prick dragging across her skin. She placed the head of my cock in the opening to her cunt as I pushed forward, but the water had washed away all of our lubricating juices, making it feel as if we were trying to dry-fuck. I grimaced as we both tried to work my cock into her, the skin pulling as I tried to push it inside. Then with a sudden shove, she slammed herself onto me and I groaned aloud, feeling the heat of her sex cover my raging cock. Our lips met again for a savage, passionate kiss as our bodies hunched together, her pubic mound grinding into me as she rode my cock hard. "Ohmygodohmygodohmygod..." she grunted as her entire body froze, her legs and arms squeezing me so hard that I could barely breathe as I continued to slam my cock into her, feeling my own orgasm rising. She kept riding out a long continuous orgasm as I pounded her harder, my hand on her ass clutching her to me as the crest washed over me and my body started convulsively bucking as I pumped my seed into her.
"Lady, that was fucking incredible," I gasped after we'd both taken a moment to catch our collective breath.
"Yeah, that was even better than I'd hoped it would be," she whispered into my ear as I pulled my softening prick out of her. "I think I'd better go check on Jerry, he was over in the bushes puking about 15 minutes ago."
It suddenly dawned on me that Sam had showed up with a date, I'd seen the guy doing shots with some of the more hardcore drinkers. "Oh shit, is he your boyfriend now?" I gaped as she adjusted her suit.
