Pulling back, he squeezed frosting along the top of his dick and then smeared some on his balls.Taking my hand, he led me off the counter and onto my ...nees on the cold tile floor. He didn't say anything; he didn't have to. I knew what he wanted as I opened my mouth wide and took his big dick inside, sucking off the frosting as he moaned. There was something salty in there too as I worked to take his big cock in my mouth. It was so big that my jaw was tired by the time I got his head to the back. I notice she doesn't ask me to call her 'Jo' again and she brings the discussion to a rather abrupt close. "We always ask at these review sessions, if you wish to end your participation, but I'm guessing that you don't?"I shake my head."Good. Well that will do for now. This is still your Usefulness Time, isn't it?" Yes, Mistress," I say."Well go, and tidy my room, Fifty. And, when you've finished return to your cell for lock in." Yes, Mistress," I say again getting to my feet and bowing my head. Between meetings the two women devised a surprise for that evening. It went into action after the dinner event at the conference.Betty said to the others, “I’ve got a bottle in my room. Let’s go there and have some fun.”After enough rounds of drink and talk, Betty started some music on her phone and dimmed the lights. “I’ve been wanting to do this all my life.” She started an amateurish strip-tease and we were an amateur audience. When she got down to her floppy tits and furry bush, she danced. He stopped right when I gasped signaling that he hit my g-spot. He made shallow thrusts to keep constant contact and with one hand, he rubbed my clit. With the other he was massaging both of my tits. By now, I was so close that I was shaking. Tripp noticed how close I was getting too.“Oh baby, your muscles are closing all around me. How close are you, baby? Your tight pussy is making it so hard for me to hold on.” I didn’t respond but instead, I returned to my back and pulled him close to.
