My Girlfriend's Younger Brother
I've been a college grad for a few years now and just recently got together with my first girlfriend, who is a couple of years younger than I am. I identify myself as bisexual, a fact that she knows.
Anyway, I met her little brother, who is a high school senior. I like my girlfriend a lot, but I find myself fixated on the idea of being naked with her brother. I fantasize about touching each other's bodies, jerking each other off, and maybe sucking on each other, possibly even more.
I think about it a lot, but I'm horribly afraid of even bringing it up to either party. I'm probably better off not doing so at all, and just ignoring those fantasies.
