What’s wrong with that?” I said taking advantage of the situation as we were both alone in the house now.“Why do you want to do that in front of...me,” Gulabo blushed, stopping short of telling me to continue my cock jerking in private.“This is my room and I can do whatever I feel like doing?” I said jokingly. “I just like rubbing my cock. It feels so good to do in front of you.”“Can’t you cover your…..Oh God…….your Lund (cock) when a lady is in the room. This is very embarrassing and you are. So I sat back and watched her drive her fingers into her wet pussy while wiggling her sexy ass. Then she pulled her ass cheeks open and said "smell my asshole". I leaned forward and took another deep breath exhaling on her asshole and pussy. My dick was so hard I could barley contain myself. She then rolled back over and began to play again for me. Rubbing her big tits and wet pussy, she was moaning louder and louder. I sat back and watched the show as she brought herself nearly to orgasm. Denning loosed his tie, and grabbed a pen. He started teaching me. A thought of him asking me to take off my clothes, and bend me over the bed had came in my mind when he told me in the class room that, he can teach me some important topics at his home. Mr. Denning was a gentleman, and he didn’t ask me to pull out my boobs for him. “And this topic is very important and very easy. Just remember this equation…” Mr. Denning was teaching me, and I started loosing my concentration. I was looking. I started rubbing it and within minutes the hot cum was out, washing down the drain. I turned off the water and dried myself. Wrapping the towel around me, I walked out of the bathroom and saw Sam still on the bed, looking sexy as ever.“Can you please tell me what I done wrong?” I walked over to the draws and took out a pair of fluffy cuffs.“What are you doing?” she said as I grabbed her arm one by one and chained then to my bed posts.I walked out of the room and went into the kitchen, drank.
