The sun was brutal that July afternoon, beating down on the private stretch of beach our family had rented for the week. Twenty-three of us — aunts, uncles, grandparents, and cousins — had taken over three beach houses in a row on the Outer Banks. Waves crashed lazily, kids screamed in the distance, and the smell of coconut sunscreen and grilled burgers hung thick in the air.
I was twenty-one. Emily, my first cousin on my mom’s side, had just turned nineteen two weeks earlier. We’d always been close, but this trip felt different. Maybe it was the heat. Maybe it was the way her tiny white bikini looked against her sun-kissed skin. Or maybe it was the fact that we’d both grown up and the innocent games we used to play as kids had started feeling dangerously adult.
Emily had always been the quiet, bookish one — long dark hair, big hazel eyes, and a body that had filled out beautifully over the last two years. I tried not to stare, but it was impossible. Especially when she was lying on her stomach on a bright pink towel, the strings of her bikini top untied so she wouldn’t get tan lines.
“Alex,” she called, lifting her head. “Can you put more sunscreen on my back? I’m burning.”
My cock twitched in my swim trunks before I even stood up.
I knelt beside her, squeezing coconut-scented lotion into my hands. Her skin was hot from the sun. I started at her shoulders, then slowly worked my way down her spine. When I reached the small of her back, just above the curve of her ass, she let out a soft sigh that went straight to my dick.
“Lower,” she whispered, barely loud enough for me to hear.
I glanced around. Most of the family was either in the water or under the big umbrellas fifty feet away. No one was paying attention. My hands slid under the edge of her bikini bottoms, rubbing the lotion over the top of her smooth, firm ass cheeks. She didn’t stop me.
“Feels good,” she murmured, face half-buried in her arms.
My heart hammered. I’d jerked off thinking about Emily more times than I cared to admit, but this was real. This was my cousin.
Later that evening, after the bonfire died down and most of the family had gone to bed, Emily found me on the back deck of the house we were sharing with three other cousins. She was wearing an oversized t-shirt and tiny sleep shorts, hair still damp from her shower.
“Can’t sleep?” she asked, sitting on the railing beside me.
“Too hot,” I lied.
She smiled knowingly. “Yeah… me too.”
We talked for a while about nothing — school, stupid family drama, how Uncle Mike drank too much again. Then the conversation died. The only sound was the ocean and the distant hum of crickets.
Emily suddenly hopped off the railing. “Come with me.”
She took my hand and led me down the wooden stairs to the beach. The moon was almost full, casting silver light across the sand. We walked until the houses were just distant glowing dots behind us.
She stopped near a cluster of tall sea grass and turned to face me.
“I’ve been thinking about something all day,” she said quietly.
“What?”
She bit her lip, looking nervous for the first time. “I’ve never… done anything. With a guy. Not really.”
My throat went dry. “You’re a virgin?”
She nodded. “But I want to try some stuff. With you.”
The words hit me like a wave. “Em… we’re cousins.”
“I know,” she whispered, stepping closer until her breasts brushed my chest. “That’s what makes it hotter.”
She kissed me first — soft, tentative, then deeper. Her tongue tasted like cherry lip balm and mint. My hands found her waist, pulling her against me. She could feel how hard I was.
Emily pulled back, breathing fast. “I want to try sucking you,” she said, voice trembling with excitement and nerves. “I want my first blowjob to be with you.”
I almost came in my shorts right there.
She dropped to her knees in the soft sand, looking up at me with those big hazel eyes. The moonlight made her look almost unreal. Her fingers hooked into my waistband and tugged my swim trunks down. My cock sprang free, thick and throbbing, the head already glistening with precum.
“Oh my god…” she breathed, staring at it. “It’s bigger than I imagined.”
She wrapped her small hand around the base, giving it a gentle squeeze. I groaned. Then she leaned forward and dragged her tongue slowly up the underside, from balls to tip, like she’d seen in videos.
“Fuck, Emily…”
She smiled shyly, then opened her mouth and took the head between her lips. The wet heat was incredible. She sucked gently, swirling her tongue around the tip, tasting my precum.
“Is this okay?” she asked, pulling off for a second.
“It’s perfect,” I rasped.
She took me deeper this time, about halfway, her cheeks hollowing. Her hand stroked the part she couldn’t fit in her mouth. She bobbed slowly, getting used to the feeling, making soft, wet sucking sounds that mixed with the waves.
I gathered her long hair in my fist, not pulling, just holding it out of her face. She looked so beautiful with my cock between her lips.
After a few minutes she grew bolder. She tried to take me all the way and gagged softly when I hit the back of her throat. Instead of pulling away, she moaned and tried again, eyes watering.
“Easy, baby,” I whispered, stroking her cheek.
She pulled off, strings of spit connecting her lips to my cock. “I want to be good at this,” she said breathlessly. “Teach me.”
I guided her gently — showing her how to use her tongue on the underside, how to suck the head while stroking the shaft, how to play with my balls. She was a fast learner. Soon she was sucking me with real rhythm, making filthy wet noises as she worked my cock.
The sight of my innocent cousin on her knees, mouth full of my dick, was almost too much.
“I’m getting close,” I warned her after ten minutes.
She pulled off just long enough to say, “I want to taste it,” then dove back down, sucking harder.
My balls tightened. I groaned her name as the first powerful spurt shot into her mouth. Emily moaned loudly, eyes wide, but she didn’t pull away. She kept sucking, swallowing every drop as I pumped rope after rope down her throat.
When I finally stopped cumming, she kept me in her mouth, gently nursing the head, milking out the last drops. Then she pulled off with a wet pop and looked up at me, lips shiny.
“Did I do good?” she asked, voice hoarse.
“You were fucking incredible,” I said, pulling her to her feet and kissing her deeply, tasting myself on her tongue.
We didn’t stop there.
Emily pushed me down onto the sand and straddled my lap, grinding her soaked pussy against my still-hard cock through her shorts.
“I’m so wet,” she whimpered. “Can I rub on you?”
She pulled her shorts aside and slid her bare, dripping pussy along my shaft. The heat of her was insane. She rode my cock like that, rubbing her swollen clit up and down the length while we made out.
“I want you inside me someday,” she whispered against my lips. “But not tonight. Tonight I just want to make you cum again.”
She slid down my body and took me back into her mouth. This time she was hungrier, sloppier. She used both hands, twisting them while she sucked the head. Saliva ran down my balls. She moaned constantly, clearly loving it.
I lasted longer the second time, but not by much. Ten minutes later I was filling her mouth again. She swallowed every drop like it was her favorite thing in the world.
We lay on the sand afterward, tangled together, listening to the ocean.
“That was the best night of my life,” she whispered.
“Mine too,” I said, kissing the top of her head.
Over the next six days of the family trip, we found every secret moment we could.
We snuck out every night after midnight. Sometimes she’d suck me on the beach. Sometimes in the outdoor shower behind the house while the water ran. Once she gave me a blowjob in the walk-in closet while the rest of the family was watching a movie in the living room. She had to cover my mouth with her hand when I came so I wouldn’t moan too loud.
By the end of the trip, Emily had become addicted to sucking my cock. She got so good at it that she could deepthroat me almost all the way and loved swallowing. She started whispering filthy things while she did it — “Cum in your cousin’s mouth, Daddy” — which drove me insane.
On our last night, she gave me the sloppiest, most passionate blowjob yet, kneeling between my legs on the deck while everyone else slept. When I finally exploded, she kept me in her mouth until I was completely soft, gently licking and kissing my cock like she didn’t want to let it go.
As we watched the sunrise together, wrapped in a blanket, she looked at me and smiled.
“This isn’t over when we go home, is it?”
I kissed her deeply. “Not a chance.”
Our secret cousin affair had only just begun — and it all started with her first incredible blowjob on a moonlit beach.
