I must have lost consciousness because the next thing I knew, Mary was gently stroking my face, cuddled up close to me."Welcome back Roberta. I have t... tell you that is the best sex I've ever had," she kissed me. "By the way what does, "Oooog glagh!" mean?" I think it means 'I'm losing my mind via multiple orgasms.' Does that happen to you?" I asked."Sometimes, can't you tell when you do it to me?" she remarked."I guess, but it looks a hell of a lot different on this side, than the other, let. It pained and I said “ma’am please stop” then she got angry and gave more beatings and told “you are my slave and I will do whatever I want and don’t shout, neighbors will hear” I said “sorry ma’am, its really painful and I can’t control not to shout and maam you stuff your panty in my mouth so that I won’t shout” She removed her panty and started to stuff in my mouth. I said “please piss your urine on your panty and stuff in my mouth” She really liked the idea and she went to bathroom. She. I knew she was busy, and probably tired from travelling, so I wasn't going to bother her. I went to bed, and started watching television, thinking to myself that when I wake up tomorrow, I'll only have to wait one more day to see her.Just as I was about to nod off, a text came in. It was Jan."Hi, are you still up?" Yea, just watching television. Trying to find something to put me to sleep." I hope I didn't wake you!" You didn't." I think the seminar will be over tomorrow by 4:00pm, then. Soon I was fucking her from behind, her huge tits swinging back and forward sexily.I thought I heard someone at the door outside and pulled out of her wet pussy in a panic.She quickly fell to her knees and started sucking my cock. There was no more noise outside so I went back to my fun.I asked Sam if she heard something but she just continued sucking, even deep throating me. She reached up and played with my ass with her finger.This was too much for me and I warned Sam that I was going to cum..
