The conversation between all of us, though, was getting redundant - there really is only so much people can talk about. My sisters even began throwing...a few sharp comments back and forth at each other, a sign that maybe our family was about to part ways again. I was actually quite happy about this turn of events as I knew I would have my mother to myself much sooner. And, so it was, towards the end of the afternoon, each of my sisters, though parting with love and kindness, decided to leave. I didn't think Dennis is going to do anything very extreme. "Is that alright? Do you understand our rules?" "Yes, sir. I mean yes, Richard." "Now Cindy, look over at Dennis and Rachel. You see he is feeling my wife's gorgeous ass. That means I should be able to feel your ass too. Is that O.K. with you?" My heart starts beating out of my chest. I don't know what to say. No man but Dennis has touched my bum. I am feeling so embarrassed. I am sure my face is so red. "Well Cindy, you don't have to. I start rubbing his cock through his pants where the others can see and he motions to go into a booth. I follow him in and within a moment or two, I am again on my knees with a fat cock in my mouth. After sucking him for a minute or so, I go ahead and tell him that I want him to finish by jerking off onto my face. He agrees and I resume my attention on his cock. He is shaved so part of the time I suck on his smooth balls while stroking his dick over my face. This really gets him hot. I go back. After pulling them up my legs and onto my body I decided to wear my mom's white six inch chunky high heeled ankle strap sandals. I felt so wonderful. I was so excited and quite aroused by this time, as well as by the sight of me in my mom's outfit in the mirror. Also, I was very aroused by the thought of the bra, panties and pantyhose being on my mom very recently, touching all of her private parts, and the pantyhose encasing my mom's oh so very ultra sexy legs that just drove me wild with.
