While a man is receiving oral sex from a woman, in the last moments right before ejaculation.
The lady, gently cups the testicles of her gentleman friend with her left hand and then with much force,
punches his scrotum with her right fist at the moment of climax. Timing is everything.
The resulting painful pleasure, is the Detroit Hand Job.
She finished me off with a Detroit Hand Job!
