I've been a lesbian for most of my life,(not butch), since my early teens at least, but I think I've always shown an interest in females. Anyhow, once, when my girlfriend of one year was not around, we lived quite far apart but I spent as much time with her as I could, I stayed over at one of my best friend's houses and this person was male.
So there we were; talking; watching television and laughing together when suddenly we notice these two people having sex in a house across the street; we could see what they were doing because of the shadows they made. This excited us both a little as we were in our teens at the time, I think we were both 16. Still being immature we decided to do different sex positions in front of the window and me being a lesbian made it comfortable for me to be like this around him. So I got on him, wrapping my legs around him as he hoisted me up onto him and wrapped his arms around me, then we started pretending we were having sex.
He was quite excited by now and had already got many erections that night as he'd fancied me for a while. When we'd finished pretending he lay me down and showed me how he had had sex with his girlfriend. As my best friend we were both comfortable doing this.
When I got up he asked me if we could kiss. I refused at first because I had had no desire for a boy for years and I didn't want to cheat on my girlfriend but then curiousity and the fact that I missed my girlfriend drove me to kissing him. This happened many times.
Although I didn't fancy him, it gave me a thrill to be doing something different and that I oughtn't to be. He had a full erection by this time and that tempted me even more as he played with my breast while we kissed some more. I hadn't seen a dick for quite a while and wanted to so I slowly ran my hand down his pants and touched his hard dick. Then I asked him to get it out so shyly he did and more thrills happened in me; my pussy was very excited by this time. Slowly I played with his balls, running my fingertips along them and then I grabbed his hard dick in my hand and pumped it up and down, going slow at first then faster and then varying.
His dick was throbbing in my hand as I pumped harder, faster, softer, slower, harder again; until finally hot cum flowed from him and as I carried on to make sure he got all the pleasure he wanted he shot his load up into the air and it landed on his stomach and chest.
