Painful teasing in metal humbler

He is not entitled to touch and worship my body even though he is my husband; just as i do with all the other men in my life, he must deserve it. i give him permission to worship my superb arse, but only as long as he suffers for my pleasure. i placed his full balls in a heavy lockable metal humbler before i sit on his face. i order him to lick my ass, and the more excited i become, the more i stretch his balls. the pain is probably intense, but his cock stays hard from licking my ass. he might be enjoying this too much, so i add a surprise ingredient to the humbler: a spiky balls crusher. the more pain i inflict on his balls, the more aroused i become. i take all the pleasure, he will feel only pain.
