It depends on what he likes and his limits.see if he has a fetish like foot fetish, peeing fetish or most of them like something shoved up their ass..in that case you could make him put things in his ass like carrots and different objects. What i personally make them do is oder them to cumm in a glass and to fill it up make a picture of it and send it to me...or put something in his ass and show it to me . that way you can humiliate him/her.Doing it online is fun but you do run out of ideas.
Ok try that maybe its something.
