Ashlynn turns on the vibrator and leaves it against your cock while she gets dressed. But she has one more trick to play on you:
"I've decided that I should intensify your training.. So I'm putting you in a chastity device. That way I can be sure that you won't do something that I don't approve of..."
You protest that this is too much. You have always been very good and never masturbate without her orders!
