Part 2: Sex in Public Bathroom
*****
“How’s the sex?” she asked as we headed toward the car.
I’d just fucked my cousin in a public bathroom. I never imagined I’d do something like that, but it felt good, more than I dared to admit. “It felt pretty good,” I said, feeling a type of optimism I hadn’t felt before. “I don’t know … but I don’t want to go home yet.”
“Me neither … How about the beach?” she suggested.
I glanced at the water. “It’s like seven o’clock. Isn’t it closed?”
She shrugged. “Since when do you care about rules?”
I almost laughed at the hypocrisy, but she was already on her phone, searching the map for the nearest access point. The last rays of sun turned the sand orange, and it was just warm enough for a swim.
“I’m not in a swimsuit,” I said.
She rolled her eyes. “We can stop at your place first, genius.”
The thought of her changing in my bedroom, maybe raiding my mom’s old drawers for a bikini, short-circuited whatever willpower I had left. “Fine. But you’re not getting my car all sandy,” I yielded.
The drive to my house took ten minutes. I called my mother beforehand, asking if Isabella could borrow a bikini. She was just happy we spent some time together, knowing Isabella constantly fought with her mother.
When we pulled in, she followed me inside, peeled her shorts off right in the entryway, and padded barefoot to my room.
“You got trunks or what?” she said.
“In the closet, top shelf,” I said, noticing the dry cum stained on her inner thighs. “But there’s not gonna be any bikinis in there. Mom let you borrow one from her.”
She disappeared into my mother’s bedroom and then came back shortly after. “Your mom has like zero fashion sense,” she said, arms crossed. “Her stuff is all one-piece and covers too much skin.”
“She’s my mom, not a pornstar.”
She giggled. “Can you call and ask if she got any skimpy ones?”
“I know she does,” I told her. “Just dig a bit deeper. She doesn’t wear them as frequently as she used to.”
A minute later, she emerged triumphant, holding up a hot pink triangle bikini with gold rings on the straps. “I take that back … my aunt is a hottie,” she said, and disappeared into the bathroom.
I took the opportunity to get changed. I pulled on trunks, found an old towel, and grabbed some sunscreen. When I came out, Isabella was waiting in the hallway, barefoot, wearing a bikini and nothing else. The top was so small it barely covered her nipples, and the bottom might as well have been dental floss.
She did a little spin, hands on her hips. “How do I look?”
“You’re gonna get arrested.”
She laughed. “Not if you keep me safe, big guy.” Then she darted past me, down the hall and out to the car, ass jiggling with every step.
*****
By the time we hit the beach parking lot, the sun was lowering in the sky. Families were packing up, but there were still a few stragglers, or teenagers like us, old guys walking dogs, and couples making out in the backs of their cars. Isabella didn’t care who saw her. She just dropped the towel on the sand and lay back, arms over her head, as if sunbathing was a competitive sport.
She wiggled her toes at me. “Get the sunscreen.”
I knelt by her, uncapped the bottle, and squeezed a huge blob onto my palm. The smell made me flash back to every family vacation we ever took as kids, except now I started getting horny again.
I started with her shoulders, spreading the white goop in slow circles. Her skin was warm and smooth, and I could feel the goosebumps rise as I worked my way down her arms.
“Don’t be shy,” she teased, eyes closed. “You gotta get everywhere.”
I glanced around. No one was looking. I ran my hands over her chest, rubbing the sunscreen into the exposed curves of her tits, careful not to pull the bikini aside by accident. She arched her back and hummed, not helping at all.
“Lower,” she said.
I moved to her stomach, feeling her abs tense and relax under my hands. The waistband of her bikini sat so low I could see the pale line where her tan stopped. I let my fingers dip under the fabric, tracing the edge, and she shivered.
“You missed a spot,” she whispered.
“I already touched you there earlier.”
I pressed my hand flat against her inner thigh, working the sunscreen all the way down to her knee. When I slid my thumb up toward her crotch, she parted her legs a little, just enough for me to feel the heat radiating between them.
I looked up. Her eyes were open now, watching me with that same lustful look. “We already had sex.”
“And?”
I shook my head. “What about your back?”
She rolled over, ass sticking straight up. “Don’t be shy,” she said and wiggled her youthful ass.
I straddled her legs, rubbing sunscreen all over her lower back and the twin slopes of her ass. The bikini bottom was a joke; I could see the shadow of her pussy lips through the fabric, and every time I touched her, she pushed back against my hands.
My cock was hard enough to hurt, trapped in the lining of my swim trunks.
“You need some too,” she said, twisting to look at me over her shoulder. “Take off your shirt.”
I did, then flopped down next to her. She sat up and scooted closer, straddling my hips, the towel bunched up under us. She pumped sunscreen into her hands, then smeared it over my chest and arms. She made a show of massaging my shoulders, digging her thumbs into the muscles like she was giving a legit spa treatment, but mostly she just wanted to feel me squirm.
For a second, I forgot we were in public. I wanted to fuck her right there on the towel, but a shriek from a nearby playground snapped me out of it.
“Let’s go in the water,” I said, needing to cool down more than anything.
She stood and ran for the surf, not looking back to see if I followed.
The water wasn’t too cold, but it was the only thing keeping me from losing control. Isabella dove in, then popped up, hair plastered to her head, nipples diamond-hard through the thin bikini. She splashed me in the face, then dove under, grabbing my ankles and pulling me off balance.
We wrestled in the shallows for a minute, then she wrapped her arms around my neck and climbed onto my back, legs locked around my waist. I could feel the heat of her crotch through my swim trunks.
She pressed her lips to my ear. “Do you want to fuck me here?” she whispered.
“You’re way too horny.”
She reached down, found my cock under the water, and squeezed. “So are you, dummy,” she said.
I looked around. A couple walked by on the far end of the sand, but we were otherwise alone.
She kept rubbing my cock, slow and sneaky, the movement hidden by the ripples on the surface. I was half in shock, half in heaven.
“If we get caught—” I started.
She squeezed harder. “Then don’t get caught.”
She pulled away, dove under, and for a second I thought she was going to blow me in the water, but she just came up for air and grinned, her face wet and glowing.
“We can go over there,” she said, pointing to a cluster of rocks at the far end of the beach. “Nobody’s there.”
I nodded. “Sure, why not.”
We swam back, grabbed the towel and scrambled out onto the rocks, feet slipping on the algae. There was a little pocket of sand between two boulders, mostly hidden from view. Isabella dropped the towel and lay back, spreading her legs so the bikini pulled tight against her pussy.
She grabbed my wrist. “You owe me a lick from earlier,” she said.
There was no way I could resist licking her. I knelt between her legs. She untied the bikini bottom, tossing it aside. Her pussy was already wet, the lips pink and glistening in the sunset.
I leaned in, licking a slow line up her slit. She moaned, throwing her head back.
“Don’t tease,” she said.
So I didn’t. I buried my face in her, tongue swirling over her clit, fingers slipping inside. She bucked her hips, grinding against my mouth, moaning louder than I expected.
It was over fast. She squeezed my head with her thighs, gasping, then went limp, legs twitching. I licked her clean, then sat back, breathless and lightheaded after having made her orgasm.
“Your turn,” she said, rolling over onto her knees.
She yanked my swim trunks down, freeing my cock. She stroked it a few times, then went down on all fours and lined it up with her pussy, still dripping from her orgasm.
“I thought you would just give me a blowjob.”
“Nope, I’m in the mood for sex … And so are you judging by that grin.”
She was right.
I pushed in, the heat and tightness overwhelming. She pressed her face to the towel, ass in the air, and I started fucking her, slow at first, then harder as she urged me on.
It was so public, so insanely risky, but that just made it better. I lost myself in the act, watching her back arch and her ass ripple with every thrust.
“Harder,” she begged. “It feels better when you fuck me harder.”
I grabbed her hips and slammed into her, the slap of skin loud in the empty cove. My balls tightened, and I knew I wasn’t going to last.
Just as I was about to finish, I heard a laugh. I looked up and saw a woman walking her dog on the trail above, watching us with a smirk. She didn’t stop, just shook her head and kept walking.
Isabella saw her too. “Hey!” she shouted. “You want to join?”
The woman cackled and waved, then disappeared around the bend.
“What the fuck was that?” I said with my cock stuffed in her pussy.
“What, you don’t like threesomes?”
I rolled my eyes.
She pulled my cock out of her pussy and turned on her back. “Come on, if you don’t want a threesome, you can at least fuck me till you come again.”
“I had no plans to stop,” I said, and lined up my cock with her pussy.
I plunged my cock inside her. The angle was perfect now that she was on her back, legs spread wide, pink bikini top barely containing her bouncing tits. Her pussy was tight and slick, making wet sounds with every thrust that mixed with the crash of waves against the rocks.
“Fuck, you feel so good,” I said, seeing her bite her lips, which looked sexy as hell. The salty ocean air mixed with her sweet perfume and the musky scent of sex created an intoxicating cocktail that made my head spin with lust and pleasure.
Isabella wrapped her legs around my waist, locking me tight in her sexual embrace. “Don’t stop,” she said, nails leaving marks on my shoulders. “I want to feel you come inside me again. I love a hot load inside my kitty.”
I fucked my cousin on a public beach. It was so taboo that it only made me harder. I could feel every ridge and fold of her pussy as I slid in and out, her walls clenching deliciously around my shaft. She was so wet that our bodies made obscene squelching sounds with each impact.
“You like your cousin’s tight little pussy?” she whispered in my ear, knowing exactly what buttons to push. “You like knowing you’re the only one who gets to fuck me like this?”
I couldn’t form words, just grunted and picked up the pace. My balls slapped against her ass with each thrust, and I could feel them tightening already. She was too perfect, too tight and too willing. The combination of physical sensation and psychological thrill was overwhelming.
Her pussy started fluttering around me, and I knew she was close again. She arched her back and then untied her bikini top at the same time. The sight of her coming beneath me, tits bouncing free from the tiny bikini, was too much.
“I’m gonna come,” I said, my thrusts becoming harder.
“Fuck, I want to feel your hot cum inside me so badly.”
That was the final button to push. I buried myself to the hilt and exploded, pumping rope after rope of cum deep into her pussy. Despite being the third climax, the orgasm was so intense my vision blurred, every nerve ending on fire as I emptied myself inside her. I could feel her walls milking me, drawing out every last drop.
When I finally pulled out, a thick stream of white cum immediately leaked from her well-fucked hole, dripping down onto the towel. She reached down and spread her pussy lips, showing me the creampie I’d left behind.
“Look what you did,” she said with a satisfied smirk. “You made such a mess.”
I watched, mesmerized, as more of my cum oozed out of her. The sight was obscenely erotic, her pink pussy gaping slightly, thoroughly used and dripping with evidence of what we’d done.
She scooped some up with her fingers and brought them to her mouth, maintaining eye contact as she sucked them. “Gosh, Isabella,” I said, my mind blown.
“What?” she said with a grin.
“I don’t know what to say … let’s just enjoy the sunset.”
I watched as Isabella found her bikini bottom in the sand and tied it back on, then did the same with her top. We settled onto the towel side by side, both of us still breathing hard. The sun hung low over the water as it was finally setting, spreading its purple golden colors over the sky and waves. The beach had mostly emptied out now, leaving us with just the sound of waves and seagulls.
Isabella leaned against my shoulder, and for once, she wasn’t trying to seduce me or make some dirty joke. She just sat there, watching the sunset with me. I wrapped my arm around her, pulling her closer.
Eventually, Mom called and said dinner was ready, and we headed back to the car. “I’ll admit it was a fun day,” I said.
“I think so too,” she said and yawned. “Hopefully, we can have some fun tomorrow too.”
We exchanged grins. “You bet … but let’s keep it legal.”
She rolled her eyes. “Yeah right.”
I gave her ass a playful spank before we slid into the car.
The end.
