Threesome fantasy - I masturbate thinking about you fucking another woman

I saw a girl at college today who was stunning and my panties were soaked just watching her beautiful body move through the room. I wanted to fuck her, but the strange thing is I want you to experience how sexy she is too. Can we fuck her together? You never knew this about me before, but threesomes make me so horny I can barely contain myself. Do you know what I like in the meantime? Stroking myself in our bed as I tell you all about her and the naughty things we'll both do to her! xoxo, Sadie
