I wanted to mount him in his chair, but I knew that he wanted a blow job first. I began to undo his pants, as Mark moved his tongue to my tits. He lic...ed and sucked my nipples through the lace making it and me very wet. When I liberated his cock from his pants Mark pushed me down by my shoulders and backed me up so that most of my body was up under the desk.I began licking the crown of his cock and Mark moaned softly. He kept his hands on the desk and didn't look down. I took him into my mouth. I sat up and looked at him. He said ‘lick it’ I looked at him and he smirked and said, ‘you have kissed my cock, you might like licking it’ I was apprehensive as I had a sense there was no turning back if I went for it.I bent down, wet puckered again and excitedly kissed his cock, this time pressing my full wet lips to his shaft. Then I slowly parted my lips and gently let the tip of my tongue touch his cock.I said to myself, ‘there I have licked cock’ So I smiled and went down on him again,. "Becky, I don't know if this is appropriate. We could both get in big trouble." Becky said, "That's exactly why we should. We both have a lot to loose, so we keep it between us. Besides I've seen you checking me out when I wear that yellow sundress to church. Gazing at my cleavage from the pulpit, Reverend pervert."Dan couldn't help it any longer. He dropped his shorts exposing his bulging hard cock, and taking off his shirt he wrapped it around the back of Becky to pull her closer to him on. So Ramesh called her to him and kissed her in front of me, without any hesitation, I was quite amazed at his and her response, Ramesh started squeezing her boobs and she very soon started unzipping him. I was the main client but still was trying to know that what was happening around there. Now I got the scene, Ramesh and Samia had already made love many times before and they were old clients for each other.It encouraged me to stop me hesitating and finally I put my pants off. Pulled my panties.
