I attend a state college. At a party I met a girl who is attending the private college in town. This is for rich kids, it is very expensive. We talked and I told her how hard it was to pay for school and that I needed a job. She told me that her brother had an extra room and that if she told him he would take me as a roommate and in return for room and board I could take care of things, housekeeping, laundry, etc.

After meeting him I agreed to the arrangement. It saved me about $700 per month, and the housekeeping, etc. was very easy.

Early one morning, there was a lot of noise coming from his room and I could hear a girl asking for it. She was very descriptive of what she wanted and he called her names. The bedroom was right next to mine and I could hear everything. I heard when they stopped and I was so awake I had to go to the bathroom. I went out into the hall as quietly as I could. When I came out of the bathroom I ran into his sister, the girl I had met at the party. She was only wearing his shirt and it was open and she was totally naked underneath.

I stayed in my room until about 8, and when I went out into the kitchen she was there. She followed me around until I finally stopped and she told me that what had happened was none of my business. That he fucked her all the time and that she liked it. That they used to live together but all they did was fuck so they got separate apartments. I told her I didn't believe her, that what she was saying was sick.

When he came out she kneeled down and unzipped him and suck his dick right in front of me. I told them that they were sick and I was moving out. I was packing my clothes and she came into my room and told me that if I wanted he would fuck me too, or if I preferred she would fuck me.

I moved out and went to a friends place to sleep on the couch. She came to find me three days later and asked me to go back, that it was just something they did, that he liked me a lot and he would fuck me all I wanted.

I went back a week later, but I left my clothes at my friends place, she was there and she told me to relax and he would fuck me. She undid my jeans and pushed them down and then my panties and sat me on the couch and told me to sit back and relax and she went down on me. He watched her, and then took me by the hand and helped me out of my top and bra and put me on his bed and fucked me.

I have a lot of sex with her and she likes to sleep with me. He gets in the middle once in a while and either has sex with me or her. He keeps trying to get me to let him fuck me in the ass, but I just can't do that. When he gets me to give him oral I spend a lot of time doing it, it is like having a pacifier, once I start I can't seen to stop until he pushes me away to fuck me.

I don't know what I am doing. I just can't stand the idea the idea of him fucking his sister. On the nights he has sex with me, all I want to do is get in bed with her and make love with her. She usually gets me to an orgasm and then waits for me to give her an orgasm too. If she fucks with him I get very upset, but I can't stop her.

From what she tells me a lot of kids in her school growing up had all kinds of sex. That is where she learned to have sex with another girl. She says she prefers to sleep with me and have sex with me, but she goes to her brother too. I know that the main reason I am with them is to be with her. From the first day at that party I have had a crush on her.
