女教练反复挑逗和否认奴隶，把他的带到顶峰，然后笑着离开

At the Pussy and Anus Licking Training Center, the slaves' libido must be constantly heightened in order to make them lick and serve with all their might. The slaves are made to stand with their hands hanging from the ceiling, with duct tape over their mouths and chastity belts on. The female instructors show the slaves their tits, rub their tits and butts against their bodies, kiss them, and perform fellatio on the chastity belt to heighten their libido. The slaves can't do anything with their hands bound, the chastity belt, and the duct tape over their mouths. The female instructors use a magic wand to stimulate the slaves' nipples and chastity belt, giggling. The female instructors repeatedly tease and denial the slaves, raising their libido to the maximum, and then walk away saying "Bye-bye, hahaha." Since the female instructors enjoy the pleasure of having the slaves lick their pussies and anuses every day, it is very important for them to heighten the libido of the slaves
