Des:I know my mothers tendencies. And I have the same masochistic traits... dont peek at the SM sex of father-in-law and mother-in-law. Seeing the ecstatic expression of her tied mother, Mai, who was interested in bondage, started masturbating. I was scolded and punished for peeking at my father-in-law when my mother was not around. Taking this as an opportunity, Meis practice continues to progress and she becomes a rope slave.
