Secret Promise

Synopsis

There is a rule between the teacher and me: first, we must not let anyone around us catch on, and second, her orders must be obeyed absolutely. She is popular among the male students—they say things like, "I’d love to cum all over that cool, bespectacled face," or "Those huge tits look like they were made for titty-fucking." Tomorrow, I’m going to make her masturbate in the boys' restroom, where guys like that hang out. She’ll have to hold her breath in a dim stall and pleasure herself while listening to the sound of them urinating. They’re bound to notice her, and she’ll end up being ravished by a crowd of boys. Just imagining it makes me want to cum, but she won't allow that.
