I cum first!

Mistress Jojo has locked her slave's head in a bondage box, but he can still use his tongue to pleasure her pussy. Jojo has been pleased with her slave's recent servitude, so as he worships her pussy she starts milking his cock, telling him that she will let him cum if he does a good job. Once she has had enough pleasure, Jojo jerks her slave's cock until he bursts a huge cum load out of it. She then makes him lick his cum off of her hand; after all, good slaves always clean up their messes.
