I am with Mistress Karino and We encourage My boy to masturbate by giving him some instructions.
He must jerk of for Us the way we like it. He must also play with his balls, massage his cock spit on his cock, and then play with his hand.
It is also good slave training, Karino and I tease him with Our boobs and sexy legs.
In the end, I count down from 5 to 0 and the boy comes almost on time with a big shot! We count it good.
