Michael didnt answer, just started pounding her ass. After only minutes he knew she was close. Hold it, he told her as he watched her. Silk groaned in...response and held it longer. She hoped he would let her come soon. It was beginning to boil inside her. Her mind was hazy with the need to explode. Michael slowed to help her control it and once he felt her cool, he started again hard and fast. This time as he felt her near he growled, Beg for what you want slave. Silk was almost out of her mind. Though at most times she seemed almost submissive, in so many ways, there was a point she could reached during sex, when she was really getting into it, when her personality would seem to change. She became very domineering and more than a little abusive towards whoever happened to be her partner. She seemed to have, at those moments, both a love of feeling and inflicting pain and I was always uncomfortable with that. This discomfort was always present, whether I happened to be the pain. So I fetched Michael, dressed him in our captured ensign's uniform, had him introduced, and he took the young lady off for a ride in a light rig. They returned. both looking a bit overheated, and adjourned to the small room on the third floor the girl had been assigned.I followed and listened from next door while they seduced each other and then joyously coupled their lusty bodies. After they had been hard at it for a bit, I quietly entered, watched and admired Michael's technique as he. During summer semester break both Swati and her brother Kunal were visiting home almost after 6 months.Due to living in restricted conditions for long Swati was also feeling really comfortable back home and was enjoying her vacations completely. One weekend her mother and father had to go out of town as to attend a roka ceremony and this incident happened during that very Saturday.At morning Swati and Kunal woke up late and started to freshen up. As there was only her brother in house Swati.
