"OK, now I can fuck you!" Shay says. She climbs on top of you and uses your cock with wild abandon.
Her pussy feels wonderful, but the damn cock-ring blocks your orgasm all too effectively.
During her fucking you manage to ask Shay if she ever used such a cock-ring on her husband.
"No," she says gasping from exertion as she rides your cock, "he always wanted to use his own self-discipline and willpower when I fucked him!"
You can't believe any man could have that much self-discipline, and you begin to wonder what kind of psychological state Mr. Fullsome was in, and by implication what state you yourself will be in after a week of this!
