My good buddy’s parents gave us permission to use their house for a spring-break party.

Steve and I are college sophomores. We don’t get back home too often, so his folks were being generous with the use of their house. But the party went south quick when the cops had to come to break up a fight. Once the police had left, Steve went off to contemplate his fate, leaving me alone with his younger sister Karen, who’s a freshman at a local community college.

We’d both had quite a bit to drink. We sat slumped on the couch among a mess of broken furniture, beer cans, and leftover food. I was wondering what Steve’s parents would say when they came home in the morning. Karen said, “Why do you look so sad? Steve is the one Dad’s going to kill, not you.” I nodded and sipped my beer. She said, “Cheer up. We’ve still got all this beer and food — we can finish the party.”

I turned to look at Karen, who is one of the cutest girls in our small town. She has blonde hair and green eyes, with a body that makes men want to fall down and worship it.

I got up to get another beer, and Karen followed me into the kitchen. The backdoor was wide open, and we could see that the mess extended out to the patio and pool. Karen said, “Let’s go for a swim.” I watched her hips sway as I followed her onto the patio, and wondered if she wore a thong, because there were no panty lines in her shorts.

I’d known Karen all my life, and didn’t think twice about undressing and diving into the pool in only my boxer shorts. I surfaced in time to see her leaning against the small diving board as she stepped out of her shorts. Still bent over, she pulled off her T-shirt and dropped it at her feet. She then went out on the diving board in just her thong and bra. She took one jump on the board and dove gracefully into the pool. I grinned at the sight of her bouncing titties.

Karen swam beneath the surface, popped up right in my face, and attempted to push my head underwater. We started wrestling. Her round breasts bumped my chest and flattened out when she leaned in close. She wrapped her strong legs around my waist as we struggled, but then became still when she felt my erection poking her belly.

We stared at each other, breathing hard, as water ran down our faces. Then our lips met. Hers were soft and her kiss was unbelievably tender. I massaged her breasts through her wet bra. After I unhooked the bra, she broke away from me, giggling, and swam off.

I gazed at the fabric in my hand for a second, then took off after her. I caught a slippery ankle and pulled Karen to me. Laughing, she spun around, splashed water in my face, then darted off again. I grabbed her leg, hauled her back, and as she twisted away I tugged at her thong. She promptly swam out of it. Her feet broke the surface once, then she disappeared.

I was searching the water for her when she grabbed my boxers and attempted to yank them down. I caught her arm and pulled her to the surface. Her breasts bobbed and swayed just above the water, her nipples erect. She tried to break loose, but I held her arms, and she wrapped her legs around my waist again. I caught her mouth with mine and nibbled on her lower lip. Then I pushed down my shorts, guided my erection to her mound, and moved it along her slit. She moaned against my mouth, and I let go of her wrists so I could pinch her nipples. She wrapped her arm around my neck and kissed me deeply. When I pushed just the tip of my cock into her twat, she squirmed and wiggled, sucking my tongue into her mouth. I squeezed her nipples and pushed in deeper. Her pussy was unbearably tight, so I just held myself there, trying to catch my breath.

We continued kissing, and after a moment I started inching farther in. Karen moaned and turned her head, breaking our kiss. I whispered against her neck, “Your pussy is so tight,” and began to thrust in circular motions. Her pussy was slick and hot. It squeezed my cock, driving me into a frenzy. Karen arched her back, leaning away from me, and I bent forward and sucked a brown nipple into my mouth. She rocked her hips, grinding her mound against me. Her orgasm pushed a long moan up from her stomach as she tossed her head from side to side, her wet hair whipping back and forth. I clamped my lips on her neck and jammed her down onto my cock as hard as I could. Then I came and filled her with my love cream.

Steve’s parents weren’t as angry about the party as we thought they would be, but we won’t be having any more bashes at their house. I can’t wait for my next vacation, though. Karen and I have a lot more swimming to do.
