My 18 year old cousin Mandy stayed with us over the summer for two weeks. We used to spend a lot of time together when we were younger, because I baby-sat for her a lot. I'm ten years older than her. Her parents moved to upstate New York a few years ago so we hadn't seen much of each other recently. Mandy just finished her first year in college and she asked my husband and I if she could come and vacation here at the shore for a while. I was only too pleased because I'm home all summer with the kids and I'd have some mature company to talk to while Jon was at work during the day.
We spent the first day catching up and hanging out around the house. My parents and brother's family came over and we just hung out on the deck with several pitchers of margaritas and had a blast. Mandy had changed a lot since I last saw her; she seemed much more adult and was looking less like a kid and more like a young girl. I noticed that immediately, but it would be a couple more days before her maturity would hit me like a ton of bricks.
A couple nights later we were sitting around watching a movie; Jon and I were on the couch and Mandy was across the room sitting in a chair. She was wearing shorts and a pink peasant top, something she'd been wearing all day, but I hadn't realized until just that moment, how gorgeous she was now. Everything about her was so soft looking... soft and rounded. She wasn't heavy, not even chubby, but just soft. She was sitting on her side, with her legs pulled under her. Her bare skin was tanned, and I became hypnotized by the smoothness of the back of her thighs. I stared at her legs as they disappeared into her shorts. The rounded ass looking so perfect as she sat there. I looked upward at her bare arms and shoulders, I'm such a shoulder person and hers were perfectly curved. The soft fine blondish hairs on her arms looked sooo sexy against her tan skin. I noted how much lighter those fine hairs were against the light brown hair on her head.
I just stared, for what seemed like forever until she looked over from the movie, catching me. I tried to be casual, and smiled wide at her, and turned back to the movie. Then I started to feel guilty for thinking the things I was about my cousin. I just couldn't help it though; maybe it was because it had been a while since I'd been with a girl. Jon knew that I had been bisexual in college, but he really didn't know how much I still thought about it. We had a family and I didn't feel like complicating things by introducing third parties, or sneaking around. I had slipped a couple times, (another story), but I suppose I shouldn't be thinking these things about my cousin. I glanced over at Jon who was watching the movie, but I know that he had noticed Mandy's transformation as well....I'd caught him checking her out earlier.
That night in bed Jon and I had sex. It was amazing as always, but during the long foreplay that preceded it, as I closed my eyes, relishing in the sensations of him licking and kissing my entire body, it dawned on me that I was imagining it was my cousin, not my husband that was making love to me.
The next day Jon went to work and me and Mandy took the kids to the beach. They are six and three and would normally have required all our attention, but as luck would have it, their friends from the neighborhood were camped nearby so all of them played, leaving the adults in peace. Mandy settled into her chair and took a book out. She sprayed some oil on her tanned legs, making them glisten and look even more delicious. She sprayed her arms and then handed me the bottle, asking me to do her back. She turned for me as I sprayed her skin and then rubbed it in a bit. I tried to be quick, but it was all I could do not to linger and savor the feel of her young skin. I applied the same oil to me and then she finished it off on my back. Her hands felt so nice, driving another flood of fantasies and more waves of guilt.
I had my sunglasses on and was tanning my back. She was wearing a pretty red tankini and as she sat in that chair lost in her book, I was able to secretly stare at her, while pretending to doze behind my glasses. My breasts and groin were pressed hard into the towel and the combination of the hot sun and erotic guilt over Mandy set my body ablaze. I tried to push myself into the towel, without giving too much away. Soon my guilt faded; maybe I was a sick deviant for wanting my cousin, but I wanted her like I've wanted nothing in a long time. I wanted to take her right there on the hot beach, our bodies slick from oil and sweat merging together. I wanted to kiss her full lips and feel her sighs of pleasure fill my mouth. I hoped I was being quiet as I felt my pussy contracting in orgasm. I know my breathing had quickened a bit. Please God let it have been quiet enough....
Later when we returned home I bathed the kids and Mandy jumped in the shower downstairs. Jon would be home soon and then we were all going out to dinner with other relatives. Once I got the kids settled I went downstairs to get some more towels from Mandy's bathroom. I heard the hairdryer running and I knocked on her door. "Come in," she said. I opened the door to find her standing there drying her hair in just her bra and panties, a gorgeous emerald green set with French cut panties. Oh my God, I got the best view of her body yet. Her breasts in that green bra were like two gifts from heaven. They were full and perfect. She was very voluptuous and her bare belly was just begging to be kissed. As I looked downward, I saw the slight bulge of her pubic mound under her panties and I instantly felt the tightening in my lower stomach and sex. To me, neatly trimmed pubic hair is one of the sexiest sights in the world. I wanted to see it so bad; no more than that, I wanted to be on my knees, brushing my lips and nose against the softness of it. I wanted to smell the delicious mixture of soap and the faintness of her arousal in that pubic hair. God almighty, how long had I been staring?
