She brought her head up, smiled, and said, “was I any good?”“yes, incredibly good” I replied. She lay beside me for a min, while I got my beat... back. Then it was my turn. Still with her heels on she lay back on the bed and opened her legs. She was fully shaved between her legs and I could see all of her vulva, it was so inviting. I began to kiss her vulva and poked my tongue out to lick her pussy. It tasted so sweet. Her pussy was so wet I could get a good bit of cum on my tongue to taste her.. Seconds later the foul smelling and tasting gag was forced into her mouth and the straps tightened.Adam delighted in telling Mandi of the sponge interior of the object wedged tightly in her throat, but more importantly of the soaking it had had for the last six hours in the urine tank of the women slaves here at the centre. (Adam stressed the word centre as if it was his pride and joy). He also took great pains to explain that as she salivated the urine trapped in the sponge would mix with her. “For the first time, mom told me I was acting very grown-up. She let me out of my promise about not letting you see me without panties. She did put a condition on me. If you were going to see me without panties, then you had to be willing to do to me what all I had been doing to you. You already know how to rub me. I am going to show you how to lick me too. If you want me to help get your semen samples, then you have to do me too. Otherwise, you can get your samples on your own.”Ok, so she. Seconds later I heard the unmistakable sound of someone beating off.“Are you jacking off?”“Duh,” he said. “I’ve got to get off. Your sister…”“Don’t say it.” “Okay, okay,” he said, “But I still gotta get off.”The fapping sound resumed. I lay there in the dark, not believing what I heard. This was just too weird.It was about to get a lot weirder.I heard shuffling, and realized that Matt had scooted close to me. Before I could react he took my hand and placed it on his cock.“Help me out, bro,” he.
