Well one way is to start by making him imagine that he's a submissive, wimpy boy who needs discipline.
Then you make sure he can only do certain things like relieve himself, with your permission.
Be prepared to spank him when necessary, and you can use some common household things to make sure he is ripe for the pickings.
First of all some twine or string, or narrow leather shoe strings would work great. Tie up his testicles, but not too tight and then make him understand that you will only be using one finger to examine him.
If he wimpers, then you know spank him and enter him. Call him some names and tell him if he releases anything without your permission, including his semen, you will severely punish him.
Ask him to do what you want him to do short of vaginal penetration, and service your needs first.
That's a start. Anything else requires ropes, pulleys, chains and an audience to watch you humiliate him.
