While Laura was sucking Mark's cock, Merrill bent me over and shoved her strap-on in my mouth. "Get it nice and wet slave!"

This seemed like old times. I was very familiar with the Mistress's strap-on. It was just a different setting. Once the full length of the ten inch dildo was thoroughly soaked, she went behind me. I felt my butt-cheeks parting with the head of her cock pressed against my anus. It slipped in easily, and I could hear encouraging his wife. "Fuck the slut boy good."
