I spread her legs even wider so that I could get to the crack between her leg,s and her pussy lips and started licking Muskan there on both sides. Jui...es were literally coming out of Mushhu ,s soft supple and drenched pussy. I could see Muskan,s juices running down on her ass cheeks and onto the bed now, she was so wet. Slowly I moved further inside, and when I finally took one cunt lip in my mouth and started to suck it hard, Muskan bucked and her hands came again to push me into her cunt. I. . Do you know the formula for me?”In response, I brought up the folder with the calculations for her dosage based on age, weight, bone mass and fat percentages and other considerations.Unhappily, she looked at me, “How do you know so much about me?”“Those tests in the lab were for just this. I needed to make absolutely sure that I had the correct numbers. On you and a few others, I had worked up preliminary parameters.”“Others?”“Do you think you were the only one I was considering for. . my wife quickly told me how hot he was getting her and would I like to watch him fuck her and we should also keep up the act that we are also strangers. I was so turned on I thought I was gonna cum instantly. As he returned i was buying her a drink she told me to buy him a drink as well then proceeded to flirt with both of us ( she knew this would turn me being told to buy a drink for the guy that was about to fuck her!) A,few more drinks later my wife lent over placing a hand on each of our. After a few minutes of doing this she released her hand from my cock took hold of my hand and placed it between her legs opening them slightly , I could feel how warm and wet she was without opening her pussy lips. I rubbed my hand up and down her lips a few times before parting her lips with my middle finger. But before I could insert my fingers inside her she placed my middle finger on to her clit , and told me to gently play there. I wanted a better look so shuffled on to my knees and turned.
