Slavery: A series of erotic games (book 04)
Getting out of my sixty-nine and freeing her mouth, Marcia said, "I haven't had a good spanking in about three weeks. Would you be willing to give me one?"
"Let me see," holding my hands out on either side of my body about chest high, "on the one hand, my right hand is sore from Evelyn's spanking." I lowered my left hand and raised my right like a balance. "On the other hand, I'd be spanking the most perfect ass I know." My hands went the other way. "It seems a little Dominant/submissive right now and you aren't wearing your collar at the moment." They switched again.
"I don't have to be in slave mode to want a spanking. I get them at other times," Marcia said, laughing.
