She knew she was changing. That much was clear. The more she played the sexy maid for her brother, the more she hungered to show off for him. The more...she watched him orgasm, the more she had come to like it. To crave it. To want even more. She was doing it for the money, doing it to make him happy and to keep paying her, but more and more she was doing it because she enjoyed it. Enjoyed it in a way she had never felt before. It did not surprise her when she felt her fingers circling her clit,. I put my cock back at her back door entrance and began to push. There was still resistance, but I was making a little head way. Finally, as we both watched, I pushed harder and my head pushed through. “Oh fuck!” she yelled, this time unable to muffle herself. “Fuck that hurts!” I held it there for a minute her two, letting her get used to the size of her anal intruder, before I began pushing forward again. I bottomed out in her and immediately pulled back and then thrust forward. I knew she was. While she was out shopping, she found a card from Melissa in the trunk, along with some other things.Susan was waiting for me when I got home."What's this," Susan calmly asked me, waving a card in my face.I recognized the card after a minute. My heart sank. I had forgotten about the affair, and the card brought back the memories. It was the card Melissa gave me the last night we spent together. She was upset that I was leaving. She had no idea I was married; I told her that my company was. She didn't seem to be offended by the remark, and came to me with her books, ready to leave.At the locker, in front of witnesses, I asked her how her day was. She replied and slipped in that I was missed. I could see in my mind her mother saying those words. We discussed homework and I got her to talk as if it was necessary for our business. I slipped in about studying and she replied that she would concentrate on her weakest subject, math.When the spectators started to get bored I stepped in.
