My sister slave and Mistress was literally shaking like a leaf. As any true submissive will tell you, it’s not easy to become a Switch. Being a true... submissive, means you are not wired to raise a hand against another. When it came time for the humiliation of my Mistress peeing in my mouth, her pee went anywhere except where it was supposed to go. I was literally drenched and not in my mouth. Naturally, Samantha was embarrassed but she’s a very staunch young lady, let me tell you. To spare her. Well, the naughty tone in her voice told me she was thinking we had been having orgies up here."Hmm, I see," she said thinking. "So, your friends, they don't know about you naked activities?" No, they don't know anything about that part of my life. We only come up here, so we can talk and sometimes play some games. I think we do this, because we already spent too much time behind our computers and televisions during the week. And well, sometimes we even do our homework up here."This made here. I thanked him and left his room with mixed feelings. I have used my own sister’s services to get the contract, at the same time I was happy I got the contract. I returned home straightaway.I went to my room, and was thinking of my sister. I thought of going to her room and thank her again for helping me in the business. I changed to my shorts and a T-shirt and went to her room. I knocked at her door.“Get in Kumar”, she shouted.I went inside. She was lying on her bed. She was wearing a tracksuit. Not sure if did it or not, but most of the accumulated drool leaked out and ran down my chin. “You slutty fucking whore, that is so damn hot!” Ben blurted, “I would love to see you suck off another person with those lips.”With a deep feeling of satisfaction, I took the head back into my mouths slushed my spit around the top of his cock. Ever so slowly I slurped and I slowly sucked his cock being careful not to take him deep. I felt a hand on my head trying to push me down a bit more, however,.
