Ok so I'm 18 I'm 5'8" blonde hair green eyes. I have a Step-sister she's 2 years younger than me. A little over a year ago we were sitting in my room, she had been sleeping in my room for about 2 weeks or so. And we were experimenting with pills and alcohol, one night we drank so much we just started making out. Then the clothes came off. I had just broken up with my boyfriend at the time and wasn't a virgin and she had never had sex before and had never masturbated to my knowledge. Anatomically we are different. I'm a 36 DD and she's an 32A so in that sense it was different. So we were making out and then to my surprise she stuck her hand down my shorts so i did the same for her. Then we were completely naked and i started licking her pussy, it was amazing i had never done it before with a girl and the way she was moaning and shaking it made me get off just watching her. Then we started 69ing with her on top it was, strangely, the best sex i had ever had, making out with her with her soft lips, and soft wet pussy lips, we started fingering each other and i remember her saying we needed to get a dildo but we didn't have one and then after all the orgasming we fell asleep naked in each others arms. We haven't really talked about it since and we haven't done anything since. I told my current boyfriend about it and he loves it, but i wish that i can find a way to have some sort of connection with her like that again, we're not blood related so at first i thought it was weird but now that i've thought about it its not as weird to me. And often i masturbate to the thought of that night. Let me know if you think its weird. thanks for listening to my story.
