There has to be a lot of trust in someone to let them do this to you and experience this kind of pain & pleasure. A woman allows her best friend to torture her nipples and sew up her vagina. Even after all of that her friend pleasure herself while she is beneath her in pain.
Tired of his bitch-slave fucking around, this master has decided on a permanent solution. "What's a permanent solution," you ask? Why, sewing her pussy shut, of course!
