GF Is So Hot But . . .

My girlfriend is super hot, great body, beautiful, really out of my league. I thought she and I had something but the first time we had sex, she was very demanding, which I didn't mind, but she pushed me down to her pussy. This was my first time having sex, but hardly her first. I started licking and sucking and I could taste and then see cum leaking out of her hole. I asked her and she said she'd just gotten fucked by an old friend. I came up to her face getting away from the dirty, used pussy and she pushed me back down. She told me to get used to it, she was no virgin and I shouldn't expect her to be. If I wanted to fuck her then get to licking again and make her cum.

I was too horned up to stop, and I went down between her legs. She rolled over with her pussy on top of my mouth and face. She asked "am I clean?" and told her I thought so, then I licked till she came. She got on top of me and gave me the fuck of my young life. Then again, I had to lick her clean, make her cum and was ready for round two.

This has become "our thing" as she calls it. She wants me to clean her pussy of mine and other guys cum. I've asked her to be exclusive and she said she never would be. I'm used to the taste and smell now, I do it but I really don't like it. I have no other person to fuck though and she is incredible. To make it better she's brought another girl in for a threesome with us. I dont' want to leave, but she tells all her friends that I clean her up after she fucks other guys.
