With her saliva mixed with mine and her round boobs with sharp nipples rubbing my chest, my dick got an erection and started poking her pussy. “What...?! Another erection and this soon? Oh… You love mommy this much?” She said happily and started kissing me on my lips and guided my dick to her pussy.As soon as my banana hit her flower, my dick attained its full length with a harder girth and she started moving her hips in circular motion, jumping up and down.The “women on top” is my favourite sex. Which, I reflectedbitterly, put him well ahead of me right now.Of course I had the more immediate problem of not fainting for lack ofoxygen, so tightly was the corset cinched. We had been wearing them forthe past week, day and night. We were allowed to remove them beforehaving a shower, which we generally took after our morning aerobics. Butthe respite was a brief one. As soon as we were clean and dry, we wouldhave to buddy up with whoever had showered with us and lace each other'scorsets up. His action caused the crack to open wide and expose the pucker hidden within. It was a clear invitation for me to fuck him and I lost no time pressing my cock to the inviting hole. Holding his hips I thrust forward and slid slickly all the way in till the base of my cock was up against his ass cheeks. He had been fucked before and was easily able to accommodate the length and thickness of my hot hard cock. Using long full strokes I fucked his ass as deeply as I could reach. Soon I was. I was so nervous and anxious. I honestly couldn't cum even if someone offered me a million to do it. So, I just kept going...and going...and going. She moaned and shook several times. I remember how she'd whimper before each climax and I really liked how I could feel her opening tighten around my penis each time she came. It worked for me. I guess it would have been worse if I had lost my load within those first few minutes. Here, my story takes a strange and unexpected twist. It is a moment.
