My cousin and I have been having sex for almost 25 years. It started when I was about 14 years old; she was 17. It began somewhat innocently. We were talking and the conversation turned to me because in a couple of days I was about to go on my first real date. My cousin kindly offered to show me how to kiss a girl, and I eagerly accepted. I always thought that my cousin was really pretty, and she had boobs. The girl I was going to date still hadn't begun to develop a chest. While our parents talked in the living room of her house she took me out back where we couldn't be seen and started to kiss. It was the first time a girl ever put her tongue in my mouth, and it was the first time I ever got a hard-on while being alone with a girl. I'm sure my cousin liked what we did too because she held me really tight and she kept pushing her crotch into mine.

A couple of months later I turned 15 and my parents had a party for me. My cousin and her mom and dad came to celebrate, and I remember that my cousin wore this really short dress. She kept on looking at me all throughout the entire party. Finally when everyone else had gone she asked me to show her one of my new video games. As soon as we went upstairs into my room she hung my "Do Not Disturb" sign on my door. She then closed and locked it. She told me that she had a present for me, but I had to turn around and close my eyes before she would give it to me. I did what she said and then a few seconds later she told me that I could turn around and see what she had.

When I did I saw that my cousin had taken off all of her clothes. It was the first time I had ever seen a naked girl in person. I'd seen them in magazines, but that was it. She showed me her entire body and encouraged me to touch her wherever I wanted to. She even made me stick my fingers into her pussy. My cock was as hard as a rock and my cousin enjoyed rubbing it through my pants. Before anything else could happen her mom called and said that it was time for them to go. My cousin quickly put on her clothes and left, and I stayed in my room for a few more minutes until my cock had gotten softer.

About two weeks later my mom told me that my cousin called and that she wanted me to come over and bring the new music CD I had told her about. Well, I hadn't told her about any new CD's because I hadn't bought any new CD's lately, but I decided to go over to her house with my newest CD anyways. I figured that she had gotten me mixed up with someone else.

It was close to dinner time when I rode my bike over to my aunt and uncle's house; we lived only about a mile away. Everything seemed normal and my cousin and I went to listen to my CD in their living room. We had listened to about three songs when my aunt and uncle came into the room and said that they were hungry, and they asked if we wanted to join them for pizza. My cousin immediately said "no", which caught me by surprise because I was hungry, and I love pizza. No sooner had my aunt and uncle's car turned the corner of their street that my cousin grabbed me by the hand and pulled me towards her room.

"What's the matter?" I asked, not having any idea as to what was going on.

"We're going to fuck," she replied with a smile as she pushed me into her room.

My cousin must have been really horny that day because she had all of her clothes off and she was starting to pull at mine before I even had any chance to think of objecting to what she had planned. The next thing I knew she was on top of my, kissing me and pushing her tongue into my mouth. She kept on rubbing her crotch into mine and in no time my cock was hard enough for her to guide it into her pussy. I never knew that anything could feel so good.

I remember her doing all of the work, rocking her hips back and forth on my cock like a well-oiled machine. She held onto me as tight as she could, and I can still recall hear her deep breaths and loud moans as I came inside of her. Long after my cock had stopped spewing cum she was still rubbing her crotch against mine as if she wanted more.

She made me promise to never tell anyone, but that was something she didn't have to worry about. A week later she took me shopping at a local mall. She made sure that we stayed out until it was dark and the we went into a drugstore and she bought some condoms. She said that she didn't want to get pregnant and that she didn't have any that first time because she really wasn't sure that we should have sex.

After that we've always tried to get together at least once a month. Even after we got married to a couple of really great people we still can't seem to get over each other.
