I know im not a lesbian or anything because I just know im attracted to guys. But there was one night that my one year younger sister and I went to a party together, it was being held at my best friends house. We got there and had a blast drinking and everythign well, by two in the morning only a few of us were left, 3 of my girlfriends and about 6 of my guy friends. We planned on staying the night. well, my guy friend jake was telling us that his deepest fantasy was to see two girls at it. Since I liked Jake I was willing to do it... but my other girlfriends said no way. And by that time my sister was trashed and falling over. Jake said I should dyke out with her for him.... I really wanted to try the whole girl girl thing once but never really had the urge. But I had a little alcholhol in me and decided to. So we were all kinda just sitting round when we decided to play spin the bottle. My sister was kinda being goofy and she spinned it. It landed on me, well of course she came over and laid one on me. This was it. The time to show Jake how hot I can really get. So I pulled her closer and started makeing out with her. Since she was drunk she just went along with it. Becuase she says the whole lesbian thing is gross even to try out. Well, all my friends were getting into it and carefuling watching us. Mostly Jake though, So I took off my sisters shirt to expose her breasts to them, Ricky was one other guy that i was pretty sure liked her. He almost grabbed em but I was quicker. I quickly undid her bra and grabebed her C cup breasts and rubbed them . She was giggling stupidly and just laid back. I was on top of her now and was dry humping her moaning. I really was liking this whole experience. I slowly unbuckled her pants to see she had no underwear and her black bush was perfect. Her pussy was better looking then mine. I just got the urge to dig in with my tounge and just took it. In a flash my head was between her legs sucking out all her fluids. It was such a turn on. Before i knew if everyone in the room was naked and we were having group sex and i ate out all my girlfriends and fucked Jake. My sister woke up the next morning knowing nothing of what happened and i hope to never tell her. But every once in a while I try to spy on her changing to get a glimpse of her pussy again.
