Mainly I fantasize about a small group of females I know in real life, that if they knew they were in said group (and what I think about them doing while fantasizing), would most likely never speak to me again.
But I wouldn't stop fantasizing about them.
The weird part is, I don't just pull my dick out and start at me thinking of fucking them. I stroke a bit in my pants still while I formulate a feasible situation where she falls for me... then I get harder and harder as I think about how I get them in my bed... then full blown masturbation commences when I finally start to have sex in my mind. Then I cum, they disappear and I realize I'm actually all alone. That's why, to quote the man show, I need two tissues when I masturbate lol.
