At the Pussy and Anus Licking Training Center, the female instructors frequently make the slaves jerk off because they cannot perform a good licking service unless their libido is heightened. In this facility, the slaves must always wear chastity belts so that they cannot jerk off on their own. The female instructors remove the slaves' chastity belts, look at their dicks, and laugh, "You've got a small dick, you've got an uncut dick, hahaha," and make the slaves jerk off in front of the female instructors. The female instructors tease the slaves who are jerking off by saying, "Do you always jerk off like that? You're leaking pre-cum, hahaha." When the slaves are about to cum, the female instructors put ice on their dicks to end their erections, and put the chastity belts back on without letting them ejaculate. The female instructors laugh and say to the slaves, "Too bad you were almost cum, hahaha. You have to keep your libido all the time, so we won't let you cum, hahaha.
