" Look brother," she pointed her finger at me, "you're stripped down to a pair of small shorts, your chest all bare and sweaty, what do you expect, th...y're healthy young girls with normal appetites you know." But sis," I said totally bemused by her comments."No but," she said, "it's time you put up and stop working my friends into a lather."Then after a short pause."So which one do you fancy most?" she asked."What? I suppose the one with the big tits," I said thinking about each of her three. I knew my father was a philander and my mom divorced him for this. My younger brother and I lived with my Mom. My father divorced three times and now lives with a divorcee without marriage certificate. What is very interesting is he became faithful to his girlfriend without marriage certificate. My Mom met a good man, also divorced like her, and they married. My younger brother became an average guy. Our stepfather’s role model affected my younger brother, so he became a simple dad for three. If only he had not gotten out of bed yesterday morning!He knew the minute he woke up without a boner, and his wife had already gotten out of bed at some ungodly hour for reasons known only to her, that things were not quite right. He felt a bit eerie about the whole thing, but decided he was being silly. He had taken the day off from work to catch up on his writing, not hide under the covers because he felt funny.He somehow got tangled up in the covers, forgot which side of the bed he was on,. The difference between their statures was working against her, so she had to try and time her movements to build up the kinetic force. It reminded her of the Mythbusters’ episode where they tried to see if a piston could take down a bridge if tuned into its resonance frequency.Soon enough, she hit the right rhythm to where Holly’s body was moving back and forth with the thrusts. She used the bouncing of Holly’s breasts to measure herself and keep in sync. The whole time, Isaac watched her.
