My first pussy(true story)

As you know, I started out gay at 11. For about 2.5 years my boyfriend and I had a great time. Then one night while my mom was out bowling things changed.
My boyfriend and I waited until my sister went to bed. Then we began our playtime. We started with kissing and touching. Then we progressed to a 69 while laying on our sides. We were slurping and moaning. I guess we got a little loud, because my bedroom door opened and closed. Then we heard my 11 year old sister say, Oh my god. We looked up at her thinking we were dead meat. Instead she came closer and asked if she could play.
My boyfriend and I said yes at the same time. My sister immediately stripped and pushed me over on my back. She got in a 69 with me and my boyfriend,Tim, got behind her and slid into her small wet pussy. She just moaned and sucked me into her mouth. Tim started pumping her pussy hard. I was sucking her little clitty and Tim's cock at the same time. As Tim started to pump Deb faster she told him to pull out and come in my mouth. He was ready and did what Deb asked. I found myself swallowing one of his biggest loads. Deb said she wanted more and we switched, with Deb and Tim in a 69 and I slid into her pussy. Then we did a repeat. I shot a big load in Tim's mouth. Deb kept begging for more. She wore us out.
After that weekend she started sharing her little girlfriends with my boyfriend and I. She would have a sleepover and she would talk her friends into bed with me and her or with both Tim and I. We would fuck the girls side by side and switch back and forth. If they wore us out, they would roll into a 69 and satisfy each other. Tim and I popped a lot of 10-13 year old cherries, courtesy of my sister.
