Oh Shit! We're Related?

It was my sophomore year in HS. I couldn't wait to see the girls in the incoming freshman class. I was in art class when she walked in. Blonde hair, blue eyes, great body, fat ass and big tits. Her name was Anne! I had to get to know her. I had to make my move. We hit it off famously! I would walk her home, I would meet her at the Friday night football games. We would talk on the phone when we weren't together. One night I walked her home one Friday night. It was a crisp fall night. I put my arm around her to keep her warm. Then we finally kissed. She was a great kisser. We were very into each other and we were extremely turned on. She reached down and felt the steel in my pants. She said "Oh my! You're so hard and I'm so wet. My parents aren't home. Do you want to come in?" She didn't have to ask again. As soon as we got in the door we made a b-line for her bedroom. We closed the door and got naked. We kissed and I fingered her as she strokes my cock. Then she sucked my cock briefly and asked if I had a condom. I did. I put it on and she got on top of me. She rode me for about 10 minutes and then she told me she was cumming. Soon after that I came too! As we recuperated on her bed we heard the door. It was her parents! Shit we needed to get dressed! I got dressed quicker than I ever had. As we sat on her bed pretending to look at pictures, her mom and dad came in to check on her. "Oh you have company" her mom said. Anne said "Mom, Dad this is Pete!" I got up to introduce myself, "Hi Mr and Mrs Decker nice to meet you!" "Likewise Pete" her parents said. We talked for a little bit and they asked where I was from. I said "I'm from town but I'm originally from Franklin." They knew lots of people from Franklin and had family there. Her mom asked me what my last name was. I said "Carducci". Her mom's eyes lit up. "Wait! Janet isn't your mom is she? And Jim your Dad?" I laughed and said "Yeah! How did you know?" Her mom couldn't believe it. "What a small world she said! Your mom and I are cousins!" I visibly started to get pale. "Really?" Anne and I asked in unison. Her mom said "Yep! That makes you 2 second cousins once removed!" I couldn't believe it. All I could think about was the kissing and the sex that took place on this bed with my cousin. "It was nice meeting you, I better get going." Anne said "I'll walk you out." Mrs Decker then said "Pete, please tell your mom I was asking for her and to give me a call." I said "Sure thing." When Anne and I got outside she put her arms around me and started kissing me. I pulled away "what are you doing?" "I'm kidding you goodbye!" She said. I stammered and stuttered and said "bbbbut we can't conttttinue! We're ccccousins! Anne said "I know! Isn't this crazy? We didn't know!" "But we know how!" I exclaimed. Anne said "I don't care! I really like you and I want to continue to see you!" I just couldn't do it! I said we can stay friends -cousins but that was it!" At first she was angry but then she understood. But that didn't stop her from hitting on me, kissing me, using sexual inuendos when we were in school and in art class. Anne did everything she could to fuck me again. I stood my ground. For as much as I liked her and wanted her I needed to keep my distance.
