Deny him after edging multiple times. You say you love his cum, so just make it unsatisfactory for him. Ruin his next say....5 orgasms?
A good pegging may be in the cards
put the dick collar on him with the large end in his mouth! Force gag as you grind hard and deep on the small stubby end
Does he know what he's done wrong? If not perhaps make him tell you what he thinks he's done and give him a spank for every time he's wrong...
Taking away his cumming privileges for a week or four might make him behave. Especially if you let him edge every night to this picture.
I would be bad every day, if this was the punishment.
I doubt that he would find that as a punishment, I sure know if enjoy it!
You can use à strapon to fuck him... I'll be jalous.... If i come with you, i'll put my dick in his mouth....
You could make him suck me off while I eat you.
