At a certain point everyone else was drunk enough, and wrapped up in a horrible unending beer pong game, one of those ones where everyone misses that final cup an obscene amount of times, that Ariel and I figured we could escape unnoticed. We got out of the hot tub, dried off, and briefly pretended to be interested in the game before subtly backing away and hurrying down the steps into the bungalow.
At the bottom of the staircase between the second and third floor, just outside her bedroom door, I turned to her, grabbed her around the waist, and pushed her up against the wall. I started kissing her, she made a surprised, excited noise into my mouth, and as we continued making out we slowly sank to the floor. She then turned and laid back up the bottom steps and I climbed on top of her and started kissing her neck. She looked up and around. There was no one in the stairwell with us, but if someone emerged from a bedroom, or came down from the deck, they'd catch us immediately.
"You're even more of a nympho than I am," she said.
I kept kissing up and down her neck.
"You have no idea," I said.
Her hands went down and shoved themselves under my waistband, found my cock. She started tugging on it, and I bit her neck lightly. Her mouth found my ear, bit my lobe. I put my hands around my waistband, pulled my swim trunks down around my thighs, and she pulled my cock free. She pulled her bikini to the side, revealing her pussy, and I pushed my cock up into her.
She gasped, looking up into my eyes, her hands coming to rest on my shoulders. I started fucking her, not quickly but forcefully, each thrust hard, driving the skin of her back into the edges of the steps. She gritted her teeth.
"This okay?" I said. "Not too painful?"
"Do you have to ask me that at this point?" she said.
I laughed. My cock pushed deep into her pussy again, and she yelped.
"Shh," I said, smiling.
"I can't help it," she whined softly. "It feels so good."
I put a hand across her mouth, making sure I wasn't blocking her nostrils, and gripped it shut. Her eyes went wide, her eyebrows pushing up her forehead.
"Are you going to be a good girl?" I asked.
She shook her head defiantly and I drove my cock up into her again, loving how firm her pussy was. She stared at me over my hand, her breath hot and wet against my palm. I loved having her pinned down like this, dominating her, and my dick swelled even harder. She must've felt it because on my next thrust she let out a long moan, her eyes rolling up into her head. I continued fucking her, the stairwell silent except for the shifting of our bodies, the heavy sound of our breathing.
Then, a voice from the stairs high above us.
"I gotta pee before overtime!"
Ariel's eyes focused on me again, wide and surprised. I stood up immediately, lifting her with me, my cock still buried in her. My trunks were still around my thighs and I hobbled into her bedroom, trying not to trip and drop her. I put my back into the door, closing it behind us, and I stood there quietly in the dark, my hands holding Ariel by the butt, both of us listening.
Footsteps descended the staircase jauntily, one of my guy friends humming to himself, and they continued past our door without stopping, heading down to the ground floor.
Ariel leaned over and flicked on a light, and we looked at each other, grinning.
"Close call," she said.
"Very," I said.
We started making out, flush with the excitement of avoiding detection. Her arms were wrapped around my upper back and I gripped her ass and started pushing her on and off my dick with my hands. She felt almost weightless, and I was able to drive my cock exactly where and how I wanted in her pussy. We fucked like this for a couple minutes, our mouths running wild over each other, her young nubile body pressed to me, the bottom of her ass lightly slapping against my upper thighs.
Then I walked us over to her bed, lifted her completely off my dick, and tossed her down onto the mattress. She gasped, landed on her butt and fell backward, her damp hair splaying out. Then she giggled, raising up onto her elbows, grinning naughtily at me. I mounted the bed on my knees, straddling her body, and brought my cock toward her mouth. She took it in her mouth hungrily and started blowing me.
I put my hands on the back of her head, gripping a handful of her hair, and held it as she sucked, making gagging noises with each push of my cock. I started muttering to myself, cursing under my breath, her mouth and the action of her tongue feeling amazing. Then I held her firm, stopping the motion of her head, and started thrusting my hips, pushing my cock as far as I could down her throat. There was only so far I could get at this angle with her head bent forward on her neck, but her lips were wrapped tight around my shaft and my dick had a back surface to push against. She kept up a long continuous low moan as my hips continued their small thrusts toward her face.
After about fifteen seconds I pulled out and she took a deep inhale, staring at my wet cock and then up at me.
"Let me lie off the bed," she said. "And you can fuck my face."
I got off of her and stood up next to the bed. She flipped onto her back and brought her head off the edge, her hair hanging loose down the side of the mattress. I straddled her head, my cock stretching down the length of her face past her chin. She looked up at my balls, hanging over her eyes. I stepped forward until they were over her mouth and she giggled appreciatively and stuck out her tongue and started licking them.
I moaned as her tongue pushed over each testicle and around my sack, and then I squatted and dropped them closer. She wrapped her lips around my left nut and sucked on it briefly, sharp pleasure shooting through me, before using her tongue to push across my sack and suck on my right nut. I started stroking my cock during this, savoring every sensation as her mouth played with my balls, incredulous that I'd gotten my balls sucked out of just a normal fuckin' day at the beach.
