My second submission here and I took notes from my first story's comments and included more dialog. I tend to write what I really like in a story and that's the slow build of tension so it may not be for those looking for a quick release. Thanks for reading and I hope you enjoy.
Part 1
The sexual tension between my cousin and I began the summer after graduating high school. We were rewarded for our efforts by our parents taking us on a trip to the Caribbean for a week. As much fun as that sounded I remember almost being annoyed by being ripped away from my friends and girlfriend right at the beginning of my first free summer as an adult. All I wanted to do was party and fuck and the last thing on my list was spending time with my family. That was until we met up at the airport and I layed eyes on Jane for the first time in several years.
We had never been particularly close, only seeing each other every couple of years as she lived several hours away with her parents. They lived in a much smaller town out in a rural area of the state and our families only got together for holidays here and there but never very consistently. The woman standing before me was a far cry from the scrawny country girl I remembered. She had grown up and she was hot!
My uncle and her were standing at the gate to board the plane as my mother and I approached. Both our parents were divorced so it would just be the four of us on this journey. My cousin had her back to me as we got closer and I briefly thought my uncle had a new girlfriend he was bringing along. I even started to ask my mom as much when she turned around, her eyes lighting up as she saw us.
I was so taken aback at first but played it off as I shook my uncle's hand and awkwardly paused before giving my cousin a half hug.
She stood almost a full inch taller than me at 6' 1". Long sandy blonde hair that fell to the middle of her back, her big expressive green eyes beaming at me over a petite, slightly upturned nose and small pouty lips. She was wearing a tank top and jean shorts which displayed her shape well. Perky C cup breasts jutted out from her chest as my eyes tracked down, sizing her up. Her wasp thin waist immediately curving back out into her shapely hips and toned thighs. Her long tan legs seemed to go on forever.
"Hey!" I managed to chirp out.
"Hey yourself! It's been a long time!" she replied.
"I'll say! I hardly recognized you! I thought your dad was bringing a new girlfriend along that he hadn't mentioned" I said while half laughing.
She laughed too, her cheeks flushing subtly red and her eyes darting away. I realized then maybe I was showing too much in my reaction and made an effort to reel in my objectifying gaze. I guess not quick enough as my uncle chimed in.
"Yeah there's a reason we're gonna have a boys room and a girls room at the hotel, can't have no mutant babies getting made on this trip between you two" he laughed.
"Gross!" my mother said, punching him in the arm.
"What! I remember what it was like to be his age and horny for anything that breathed." he retorted.
My uncle reaching out and grabbing me in a half head lock before tousling my hair. My mother smiling and rolling her eyes. My uncle had always been crude in his sense of humor.
Just then the plane began to board and we gathered our things to head to the gate. I couldn't help but steal a side glance as my cousin bent at the waist to grab her duffel bag. The fabric of her jean shorts riding up slightly and straining to contain a perfect onion shaped ass.
The flight was smooth and several hours later we were landing in Cancun with the final destination of Cozumel for a week of beaches, food, and drinks with little umbrellas. I got over my annoyance of having been pulled away from my social scene and began to get very excited as the Gulf of Mexico transitioned into the teal water of the Caribbean.
We boarded a bus to Playa Del Carmen where we'd take a ferry to Cozumel. My cousin and I sat together and got to catch up for a while as we'd been seated separately on the plane. I managed to keep my focus on the conversation and not get distracted by how much her beauty had stunned me. I knew it was wrong to have such thoughts anyway and besides, I did have a girlfriend who I cared for very much.
Not quite sure if it was actual love but we had lost our virginities to each other on graduation night so the attachment was very strong. Our conversation eventually lead in the direction of our current romantic partners.
"You have a girlfriend?" she asked.
"I do! How about yourself?" I replied.
"Well I have a boyfriend if thats what you meant" she laughed.
"That's what I meant!" I confirmed.
"Are you guys banging?"
I was taken aback by her forwardness and chuckled. Glancing to the seats behind us to make sure our parents hadn't heard.
"Mmhmmm" I smiled. "You?"
"Hell yeah we are!"
I couldn't believe how quickly and comfortably she had brought up the subject but it definitely helped to quell any awkwardness between us having not seen each other in so many years. It instantly felt like a wall had been brought down and we now had an actual connection in the form of a shared secret. I had told a few friends about losing my virginity but for the most part had not talked about it too much with anyone not closely connected.
Knowing she was sexually active stirred something inside me that I don't think I directly acknowledged. As the bus ambled along and conversation dwindled I found my gaze lingering from time to time on the beads of sweat gathering in the slight amount of cleavage her tank top allowed.
We finally arrived at the hotel around sunset and being so wiped out from the journey we all decided to just have dinner at the hotel restaurant and save any exploration for the next day. Dinner was uneventful expcept for our parents allowing us both to have a drink with our meal, the legal drinking age being lower in Mexico. They were both pretty cool parents within limits but it seemed like a good sign that we might have more fun than we expected on this trip.
Saying our goodnights to my mom and cousin, my uncle and I retired to the room we'd be sharing. He opted to have a few more beers on the balcony while I hopped in the shower. Being a horny teenager it wasn't long before I was rubbing one out in the shower, thinking about fucking my girlfriend. Right as I was about to cum, the image of my cousin's thick round ass in her jean shorts flashed through my mind and I came so hard I almost lost my balance, leaning forward against the wall to catch my breath.
I couldn't believe how intense my orgasm had been and immediately felt the shame of forbidden lust wash over me. I finished showering and dried off, pretty much making a bee line for my bed. I didn't want to face my uncle having just jerked off to his daughter and feeling like he would somehow read it on me. He tried to get me to come have a beer with him but I feigned being too tired and crawled into my bed. I tried my best to drift off but I kept seeing my cousin's ass in my mind and did my best to ignore the growing hardness in my underwear.
The next day we all woke up at a reasonable hour and met for breakfast in the hotel restaurant. Plans for the day involved renting a car and getting the lay of the land with some beach time in the afternoon. My mind drifted wondering what sort of swimwear my cousin might be rocking. She did not disappoint.
It wasn't exceptionally risque as far as bikinis go, no thong bottoms or micro tops and I knew not to expect as much, this being a family vacation and all. But goddamn I could hardly hide my reaction when she removed her tank top and jean shorts when we got to the beach that afternoon.
Thankfully no one caught it as there was plenty to look at in every direction but I was singularly focused on her tight tan body as her tits plopped out from under her tanktop and she wiggled her shorts down around her perfect ass. The bikini bottoms working hard to contain her ample flesh.
"Christ almighty girl," my uncle said. "Where the hell is the rest of your swimsuit?"
"Ugh shut up Dad! It's just a bikini, covers the same as underwear!" my cousin replied.
"Well I better not catch any of these dudes oggling you, that goes for you too!" He said, looking directly at me.
"What? Ew she's my cousin man!" I said. Doing my best to sound convincing but feeling like I'd been busted.
"Still..." he trailed off but with a friendly smile.
"Don't be a degenerate!" my mother scolded him.
"Whatever." my cousin said, "Race you to the water?" she directed at me with a raised eyebrow.
"You're on!" I said, thankful for the easy out.
We sprinted off in the direction of the water in a dead heat. We were neck and neck for the better part of it but I found myself slowing ever so slightly to get a quick view of her ass bouncing and swaying right before we plunged in.
The next few days were pretty much a rinse and repeat of spending the day browsing the shops and eating, with afternoons and evenings spent at the beach relaxing. The small amount of one on one time we were able to spend together was always easy and comfortable, laughing and carrying conversation was never forced. I was genuinely enjoying getting to catch up with her and silently berated myself for my unnatural urges.
There were even brief moments where we were mistaken for a couple by locals or other tourists and one time where she had me pretend to be her boyfriend to thwart the advances of a drunk pair of travellers. I tried not to think too much of it but I couldn't deny the chemistry we seemed to share.
