Slavery: A series of erotic games (Book 03)
In the event Julia didn't recognize the signals, I said, "Your slave just orgasmed."
Rhonda whimpered.
"I recognized the signs of a climaxing slave, Master. I will let you punish her. You can spank her far harder than I can. Will you behave now, slave, or should we go for double the punishment?"
"Domina, there's another orgasm on its way. Please let your slave cum?"
"If I let you cum tonight. You won't be able to cum again until Friday. Three days without cumming. Is that what you want?"
"Please, Domina. I don't think I can hold off until Master cums unless he cums now."
