Eight years ago when I was a scrawny little blonde about two months short of my 13th birthday my sister (who was 18), her boyfriend and I traveled out of town to a concert several hours from home. After the concert we had a hotel room for the night. We went to bed then after they apparently thought I was asleep I could tell they were making out. I waited a while then when I couldn’t get to sleep I said “You guys are having too much fun.” At first they didn’t say anything then I heard her boyfriend saying something to her. When my sister ask if I wanted to have fun with then I said “Sure” got up and jumped in bed with them. My sister said ‘We were just kidding you know?” I told her I knew but I was going to sleep with them anyway. They just went back to what they were doing. I heard my sister whisper something to him but couldn’t hear what she said. I had on a sleep shirt and p****** then I felt her boyfriends hand touching my little b***. I didn’t say anything really enjoying it. Then my sister ask if I wanted to play more running her hand up my shirt beginning to finger me. All the time they were having s** so I just let them have their fun so before long they had me very excited. He kept playing with my b*** and before they were finished my sister had me a real mess with her fingers. i hadn’t said a word then my sister wanted to know if I had had fun. I was so excited I quickly said “Yes!!”. I was shocked when she wanted to know if I wanted to have more fun with her boyfriend. I said “Really??” and she said it was up to me. I ask her what she thought to which she told me she had gotten me ready and thought I would probably enjoy it. Her boyfriend hadn’t said anything so I ask him what he thought. He just ran his hand up my shirt touch me then told me he though I was definitely ready. My sister said “Well?” so I told her ok. She told me to take my p****** off which I did then he got on me and she told him to be easy. She had gotten me really messy so he didn’t have any trouble getting in me. I immediately let out a loud “Ahhhhhh” and they wanted to know if I was ok and I said “YES…..that’s good!!”. Every time he would go deep I would let out a little moan so my sister told me not to enjoy it so much because I was making her look bad then she laughed. After a couple of minutes I got a weird feeling all over and yelled out “Ohhh my God” pushing hard to get him deep and her boyfriend said “Holy s***…she just came big time”. My sister yelled “Oh God ….that’s not good don’t come in her!!!” but he told her it was too late as I could feel him filling me up and I let out another loud pleasurable sign. I thought my sister was going to die. I ask her if I was in trouble but she said not to worry I had had a good time we’d just have to wait and see. She wanted to know if i had enjoyed it so I told her it had been really fun. She knew my period wasn’t due for several days but when it got close she ask every time she got a chance if it had come. Thankfully, I got an early 13th birthday present by getting my period right on time. She told me she had really been worried that I was going to be pregnant.
