We would finish this month's insemination process on Sunday night.The science professor was going to give me a 2 liter beaker of liquid nitrogen to br...ng the storage container back up to the full mark tonight. I had been keeping an eye on the marks. I had the container for almost five months and this was the first time that I needed to add anything to it. I was pleased that it was working out so well.After lunch Patti and my luck both changed. Patti found out from an older store employee at the. If I would not have sex with her, she would blow me just to touch a penis again. I ask why she did nto do this with the regular driver, she told he had heart problems. In the bedroom she did not take long to get me undressed, and she dove right on my cock with her lips. I laid on the bed as she got me hard, she jumped on top of me. I laid there like her toy, while she ride me and moaned her brains out. I watched her tits bounce and then played with each of them. I enjoyed the sex part, but had. Plz do it more. I did it for some time and moved to her boobs i started kissing them through the t-shirt and asked her to remove the t-shirt but she didn’t agree after sometime she agreed as i rapidly requested her.As she removed the t-shirt i started kissing on of the boobs and pressing the other with one hand. Doing that i slowly moved one of my hands to her pussy and could feel her pussy through her 3/4th. I inserted my hand into her 3/4th and touched her pussy as she didn’t wear a panty i. ..how do you fuck for that long? He busted out laughing and said no dummy...the tickets! OH , shit man I thank you very much. Just then my wife came in wearing a pair of terry cloth white shorts and a white wife beater. Her tan legs looked so hot next to that white. I looked at her and said, so what where you doing in the bathroom for an hour? She smiled and said I was taking a shower when some one stuck a dick in my face....so one thing lead to another and I got my pussy tore up. My head.
