We are determined to train our new slave to become an oral sex expert, starting with his lessons on a real cock. He must learn to jerk, suck, and delicately lick the balls until climax. We guide him through the process, correcting his mistakes and teaching him how to improve. After much practice, he finally succeeds in bringing the cock to orgasm and graciously swallows every last drop. This is only the beginning of many more lessons to come for our eager trainee.
