My wife trained me

“You lose!” my wife laughed as I failed to swallow all the cum from the big black cock I was sucking, despite me assuring her that I would.
The penalty is to be no more black cocks for a whole month! Sure I can still suck them hard for HER, but I’ll not be allowed to finish one off!
My wife trained me to love black cock, then stops me sucking them as punishment!
