Anonymous sex fantasies SeXStoRY

In college I had two hours between classes, and I would masturbate in the bathroom stall. I would get so hard thinking of someone catching me and sucking their dick. Just when its hard and wet i'd sit them down and sit on their dick pushing it into my ass. Riding them till we both cum. I'd cum hard to this. Sometimes finger my ass Any hot fantasies want to share? :)
