Making love to Jen should have been nothing more than a beautiful wet dream for me. She is after all, my sister. It's one thing for me to fantasize about kissing my sister's sensuous lips, sucking on the tender and puffy nipples of her pert breasts, gently parting the petals of her sultry womanhood with my eager tongue, tasting her juices as they lubricate her warm and inviting pussy, her eyes imploring me to look deep into them as she emphatically wraps her arms and legs around my body and pulls me into her, and another thing entirely to experience it in the flesh.
Any healthy male would gladly give his left nut to spend a single night with my sister. She's thin and petite with long blonde hair, glowing soft skin, sparkling blue eyes and an innocent smile. She had the demeanor and look of the typical girl next door. I've said before that she resembles a young Gwyneth Paltrow. Sure she was gorgeous and a sweetheart as well, but if I said that the fact that what we were doing was taboo didn't heighten the experience for both of us, I would be lying. And the risk that our parents might find out about our forbidden love amplified our affair. The fact that we were both virgins made the exploration of each other's bodies even more enticing. There was another added component: We were pretty sure we were in love with one another. It sure felt like love. I hadn't desired anyone like I desired my own sister. How was any of this even possible?
Our vacation in Cancun felt like a honeymoon of sorts for us. We begged out of most of the plans our parents had made for the family. Mom and Dad kept busy while we mostly hung out by the pool and when we couldn't keep our hands off each other, we would retreat to the privacy of our shared bedroom, quickly slide out of our bathing suits and jump into bed. Mom and Dad continued to think I was still sleeping on the air mattress in Jen's room, when unbeknownst to them, it had actually become our little den of forbidden desire.
Having dinner most evenings with our parents became weird. I doubt we would be having these pleasant harmonious dinners with them had they been aware that their only son and daughter had just fucked each other hours earlier under the same roof. Jen and I would often tease each other and make small talk at dinner, while playing footsie under the table.
"So Jason, what did you do today, while Mom and Dad were out parasailing?" Jen asked me.
"Not much Jen," I responded, "Just lounged by the pool most of the day. Took a nap. That air mattress is depriving me of sleep, you know."
"I'll tell you what little brother, you can sleep in the bed tonight and I'll sleep on the air mattress." Jen offered with a mischievous gleam in her eye.
"Thanks Jen! You're the best sister ever," I responded.
"Oh my! It's so good to see you kids getting along," Mom remarked. "Are you sure you're both feeling alright? You both haven't come down with some tropical fever, have you?"
Jen and I were always scheming of how we could find time to be alone together. One day, Jen and I rented a small boat and had fun sightseeing. And fucking on the boat, of course. What did you expect by now? We found a private little cove where we were able to skinny dip and fuck in the water as well. Afterwards, Jen and I did some shopping and we bought each other a set of inexpensive rings that cost us about 1,100 pesos each. We gave them to each other as a sign of our enduring love and betrothal to each other. It turned out to be a fun vacation and in the end we were glad that Mom and Dad made us join them. It was their anniversary, but for us it truly felt like our honeymoon.
One night I came up with the idea for us to join the mile high club on the plane ride home. I suggested we put the last of our money together and buy our folks seating upgrades to first class, which luckily were available. We told our parents it was our anniversary present to them. They said it was a thoughtful gift, but we only did it because we were two sexually depraved individuals who just wanted to be alone together and bone each other on the plane. These are the sorts of things you can only think of when you're horny and motivated for your sister's snatch or your brother's cock.
Jen and I started making out as soon as we hit our plane seats back in coach, while our parents reclined up in first class. We didn't even wait for the plane to taxi down the runway before we started groping each other. People were still boarding the plane. A friendly elderly couple seated in the aisle across from us smiled at us, then the white haired lady leaned over and spoke to Jen directly, "Are you two on your honeymoon? They say that married couples start to look like each other the longer they're married, but you two look like you could already be sister and brother."
Jen looked at the lady and wrinkled her nose, "Sister and brother? Ha ha! That would be wrong!"
The kissing and groping and hand holding aside, the nosy old lady must have thought we were married because of our "wedding" rings, which even our parents failed to notice. Our parents are in the dictionary under the word clueless.
Sex on the plane for the most part was awkward and quick. Mile high sex is not all it's cracked up to be. We waited for the middle of the flight when snacks and beverages were being served, keeping the stewardesses preoccupied. Jen walked to the back of the plane and entered an unoccupied restroom. I followed a few minutes later with a tampon in my hand, mentioning to the elderly lady across the aisle that my wife forgot her tampon and I better get it to her. "She's going to be looking for this!" I said.
The elderly lady smiled and winked at me and said, "Sure. You better give it to her. Quick."
I gave it to her quick all right. Did she know what we had planned? I quietly knocked on the restroom door and Jen let me in. She had prepared herself for me ahead of time by wearing a short skirt and no panties and had already propped herself up on the sink at waist level, her legs spread wide apart. Facing her, I pulled down my pants and didn't hesitate to enter her. No time for oral, I thought. It didn't take me long to come in her pussy. Unfortunately, this left Jen a bit unsatisfied but she didn't seem to mind. She was an unselfish, giving lover. Afterwards, she snatched the tampon from my hand and said, "Good thinking. This will stop your cum from dripping out of my panty-less pussy for the rest of the flight."
