Your submissive girlfriend has a chastity kink and asked you to be in charge of her orgasms. You tell her when she can touch herself, and tell her when to cum. You go to her apartment to surprise her and what do you find? She's touching herself without you! After about a minute of playing with herself she opens her eyes and sees you there. She jumps, "Oh, hi Daddy! When did you get here?" she tries to explain that she wasn't just touching herself without permission. You tell her it's too late and to keep touching herself, so she happily agrees. She's so horny right now. You watch her get close to orgasm and tell her to stop what she's doing and to slap her inner thigh 5 times. This pattern continues, and each time she begs more and more to please let her cum. You finally agree to let her cum, but you tell her as soon as she begins to orgasm she needs to stop touching herself. She agrees because she just wants a release! You watch her come to the edge of orgasm and then ruin it, letting the waves wash over her. She thanks you for letting her finally cum, and then she goes to make snacks.
