On my twelfth birthday, my sister who was a year and a half older, told me she had a birthday gift for me. She then led me into the garage behind the house. In the garage she opened the car door and sat down on the floor board. She then grabbed my pants at the waist and pulled me to her. Unbuttoning my pants I said "what are you doing" and she responded "giving you your present". At that point I didn't know what to do so I just stood there. She pulled my member out and started rubbing it, I couldn't help myself at that point I had to let it happen. She proceeded to suck my member, and it didn't take me long to reach down to rub her breasts. It only took her about 2 minutes to bring me to ******. I thought my legs were going to give out. Looking back, she was a pro at this, she had done this before. She continued to molest me (without resistance at all ) once a week or so for about a year. Most of the time she would ignore me around the house, and then I would catch a glance from her like a long stare, and I knew she was coming to my room that night. We did about every means of foreplay to reach ****** that you could imagine. Then about four months into our affair, and I use that term loosely, the foreplay ended one night in penetration. At first she just slid the head of my member in and out real quick as I tried to shove it back in she said no, I don't want to get pregnant. She told me tomarrow, I'll get something from a friend of mine. The very next night she came to my room with a condom. I was alread fully erect when she came in. She got into bed with me and started rubbing my member, I was ready now I told her. She slid the condom on me, by the time I got to her opening I was already humping, I was like a dog in heat. We both came instantly, and it only got better with time. The day I realized it us over, I was sad. She told me she had a boyfiend now and gave me one last roll in the bed.
