Slavery: A series of erotic games (book 04)
Shasta said, "Mrs. Thornhill, when I initially asked this favor of your husband, I offered the use of my slave to pleasure his. Unfortunately, my slave is being punished because he thinks he's my boyfriend as opposed to my slave. I apologize as I feel you should be repaid for my use of your husband. I'm willing to pleasure you but I can assure you, I'm not nearly as good at having sex with a woman as I am a man, but I will try if you wish. I've tried it a few times recently and found I can enjoy it. If you would prefer someone experienced, perhaps Sam would loan you one of his and I will serve as their replacement."
"I just got fucked by three people, arranged by my husband for my pleasure.
