We had to do a lot of sorting from a box of files. Sheila smiled at me and said. "Let's play big boss." She picked up the box and walked right back in...o Bob's office. I couldn't believe she was taking such a big chance when she told me we would use his big conference table to do our sorting. We started our work and kept at it, but I couldn't ignore both the surroundings I was in and, most of all, the view out the window. After a while, I stopped what I was doing and just stood there looking. Abby soon had her legs around my back. Her pussy muscles were gripping me hard. Maybe it was because I was fucking my own sister. I got more worked up than normal and I tried hard to control myself.After maybe a half hour had passed, I told Abby I couldn't hold it much longer and I was about to pull out.No Tom, stay inside me!" She cried out.There was no time to debate the matter. My sister still had her legs locked around me. I pushed into my sister's pussy as hard as I could and I unloaded.. “Oh, I’ll never be able to get off from just that.” I said, hoping she’d come back with renewed fervor. “Ohhh, well all you had to do was ask, mister”, I heard her move around and then saw her ass pressed against the hole, her clean shaved pussy and tight little asshole on display. I tried to stifle a moan as my cock twitched. “Good girl”, I managed to get out as I reached forward and gently rubbed my fingers along her pussy. “Pussy only”, She said, “master said my ass is for him only” I smiled. His eyes were still burning into hers, her body feeling like a limp rag doll underneath him as he took what he wanted with his cock.She continued to screech in pain as he forced his way in and out of her again and again. She’d wanted to wait for someone special. She’d wanted her first time to be sweet romantic lovemaking, and now here was this monster shattering all of her dreams of that, brutally raping her. Her body trembled violently as she silently prayed for it all to be over quickly. She.
