lil cousin (18M) enjoys Bathtub Sex with me (21f) during family vacation

My family decided to rent a massive lake house for our annual summer vacation. It was supposed to be a wholesome week of swimming, barbecues, and quality family time. Instead, it became the most sinful week of my life.

My cousin Noah, 18, had just finished high school and was about to head off to college in the fall. I'd always thought he was cute, but he was just a kid, right? Wrong. Noah had grown up over the past year. He was tall now, around six feet, with broad shoulders and this lean, athletic build from playing soccer. His dark hair was always messy in that effortlessly sexy way, and his hazel eyes had this mischievous glint that made my stomach flip every time he looked at me.

We'd always been close growing up, the two cousins who'd get into trouble together at family gatherings. But this trip was different. The tension between us was palpable, electric, building with every accidental brush of skin and lingering glance.

The lake house was huge, with six bedrooms, a massive deck, and a hot tub on the patio. But the best feature by far was the master bathroom on the second floor. It had this enormous clawfoot tub, big enough for two people, maybe three. I'd been eyeing it since we arrived, dreaming of long, hot baths away from the chaos of my extended family.

Little did I know, I'd be sharing that tub with my cousin.

It was the third night of the vacation. Everyone else had gone to bed early after a long day of swimming and hiking. My mom and aunt had drunk too much wine and passed out on the couches. My uncle was snoring loudly in his room. The house was quiet, peaceful, and I was wide awake.

I'd been tossing and turning for hours, my mind racing with thoughts I shouldn't be having. Thoughts about Noah. About the way his wet shirt had clung to his chest after he'd jumped in the lake. About the way he'd looked at me when he thought I wasn't watching.

Desperate for some relief, I decided to take a bath. The master bathroom was empty, and the clawfoot tub was calling my name. I filled it with hot water, added some lavender bath salts, and slipped in with a satisfied sigh.

The water was perfect, hot enough to relax my muscles but not so hot that I couldn't bear it. I leaned back, closing my eyes, letting my mind drift. My fingers traced lazy circles on my stomach, dipping lower, thinking about the forbidden thoughts that had been plaguing me all week.

The door creaked open.

My eyes flew open, and I saw Noah standing in the doorway, his eyes wide.

"Shit," he breathed. "I'm so sorry, Anya. I didn't know you were in here."

He started to back out, but something stopped him. Or maybe something stopped me from telling him to leave.

"Wait," I said, my voice softer than I intended. "It's okay. I don't mind."

He froze, his eyes raking over me. The water was clear enough that he could see everything—my breasts, the curve of my hips, the dark patch of hair between my legs.

"You don't mind?" he repeated, his voice hoarse.

I shook my head slowly. "Come in. The water's big enough for two."

He hesitated for a moment, his jaw tight. Then he pulled off his shirt, revealing his lean, muscular chest. My mouth went dry as I watched him unbutton his jeans and slide them down his legs. He was wearing black boxer briefs that did nothing to hide his arousal.

He stepped into the tub, and the water rose as he settled in across from me. We were both submerged, but the water was clear, and I could see every inch of him.

"This is crazy," he said, his voice barely above a whisper.

"I know," I replied, my heart pounding. "But I can't stop thinking about you, Noah. I've been thinking about you all week."

His eyes darkened. "Me too. Fuck, Anya, I've been going crazy. Watching you in that bikini, seeing you laugh, smelling your perfume. I couldn't take it."

"Then don't take it," I said, moving toward him. "Just... do something."

He didn't need any more encouragement. He closed the distance between us, his hands cupping my face as he kissed me. The kiss was explosive, hungry, months of pent-up desire finally breaking free. His tongue invaded my mouth, and I moaned, wrapping my arms around his neck.

"This is so wrong," he murmured against my lips.

"I don't care," I gasped. "I want you."

His hands roamed my body, sliding down my back to cup my ass. He pulled me onto his lap, and I felt his hard cock pressing against my thigh through his boxers. I reached down, stroking him through the wet fabric, and he groaned.

"Fuck, Anya," he breathed. "You're going to make me come before we even start."

"Then let's start," I said, pushing his boxers down.

He kicked them off, and his cock sprang free, thick and hard and absolutely perfect. I positioned myself over him, the head of his cock pressing against my entrance.

"Tell me you want this," I said. "I need to hear you say it."

"I want this," he said, his voice desperate. "I've wanted this for so long, Anya. Please."

I sank down onto him, and we both gasped. He was so deep, filling me completely. The water sloshed around us as I began to move, riding him with a rhythm that was slow and deliberate at first.

"Fuck, you feel so good," he groaned, his hands gripping my hips. "So tight. So perfect."

"You're so big," I breathed, my head falling back. "I can feel you everywhere."

He thrust up to meet my movements, the water splashing over the edge of the tub. I leaned forward, my breasts pressing against his chest, and kissed him again.

"Faster," I urged. "Fuck me faster, Noah."

He flipped us over, positioning me so I was bent over the edge of the tub. He entered me from behind, and I cried out as he slammed into me.

"This is what you wanted?" he asked, his voice rough with need. "You wanted your little cousin to fuck you?"

"Yes," I screamed, not caring who might hear. "Yes, Noah, yes!"

His pace was relentless, his hands gripping my hips as he pounded into me. The water was splashing everywhere, soaking the floor, but neither of us cared. All that mattered was the feeling of him inside me, the sounds of our bodies slapping together, the filthy words he was whispering in my ear.

"You're such a dirty girl," he said, spanking me lightly. "Getting fucked by your cousin in the bathtub. What would everyone think?"

"I don't care," I gasped. "Just don't stop. Please, don't stop."

His hand reached around to my clit, rubbing in frantic circles. I was already close, the pressure building with every thrust.

"Come for me," he demanded. "I want to feel you come on my cock."

I shattered, screaming his name as my orgasm ripped through me. My walls clenched around him, and he groaned, his rhythm faltering.

"Where do you want me?" he asked, his voice strained.

"Inside," I begged. "I want to feel you come inside me."

He thrust deep, and I felt his hot seed flooding me as he came. He collapsed against me, his body shuddering with the force of his orgasm.

We stayed like that for a long moment, both panting, the water slowly cooling around us.

"We should probably get out," I said, laughing breathlessly.

"Probably," he agreed. "But I'm not done with you yet."

He pulled out of me, and before I could protest, he lifted me out of the tub and laid me down on the fluffy rug next to it. He positioned himself between my legs, his cock already hard again.

"Round two?" I asked, raising an eyebrow.

"Round two," he confirmed, pushing inside me again. "And maybe round three after that."

This time, he was on top, and I wrapped my legs around his waist as he fucked me. His mouth found my neck, my breasts, my lips, his kisses leaving a trail of fire on my skin.

"You're so beautiful," he murmured. "I can't believe this is happening."

"Believe it," I said, pulling him closer. "And don't ever forget it."

He thrust harder, deeper, and I met each movement with equal passion. The second orgasm came quickly, both of us desperate and hungry.

When we finally collapsed, spent and satisfied, we lay tangled together on the rug, not caring that we were dripping wet.

"That was the best night of my life," Noah admitted, his head resting on my chest.

"Mine too," I said, stroking his hair. "But we can't tell anyone."

He laughed. "Who would believe us?"

The next morning, we acted like nothing had happened. At breakfast, Noah sat across from me, stealing glances that made my stomach flip. My aunt was babbling about her plans for the day, and my mom was complaining about the lack of coffee filters.

But under the table, Noah's foot was rubbing against mine. And when I looked up, he winked at me, a secret smile playing on his lips.

That night, we did it again. And the night after that.

By the end of the week, we'd christened every room in the lake house. The kitchen counter, the deck, the hammock outside, the shower, and of course, the bathtub.

I know it's wrong. I know it's taboo. But when I think about those nights with Noah, I can't bring myself to regret a single moment.
