Spanking. Originally a punishment, but for masochistic women who have been trained, it might as well be a reward... On all fours, bound, during sex, asses slapped in various situations. The harder you spank, the redder the ass becomes, along with the juices flowing from their pussies. The sounds of women leaking when their asses are spanked—are they moans of despair or screams of joy...? Witness the forms of 8 women drowning in the pleasure of being trained.
