Slavery: A series of erotic games (book 04)
Chen said, smiling, "and on your knees is a good place to start."
"Are you good?" I asked Evelyn, smiling.
"Yes, very good, Julia."
"Then I shall play with Reneé and Janet," I said, "since you seem to be doing fine by yourself."
While I licked Janet and Reneé, Evelyn sucked Chen. He would be easy. He was shorter and thinner than her Master. She had no difficulty nor hesitation in taking him all the way in her throat. I don't know how many times Chen had climaxed today, but he easily lasted ten minutes before he released. Long enough for me to give Janet and Reneé two orgasms apiece.
