I could see the confusion on mum's face. She was caught between desire and love, and the social conventions of our time.For the rest of the afternoon ...we chatted, although it was strained, as I could tell mum was being overly cautious. However, within a half hour we were back to the mother and son of yesterday. 'Time to make my move' I thought, and then the opportunity arose. Mum suggested we have a tes and I volunteered to help her, and in the confines of the small kitchenette of the apartment. I was only halfway in.I was teasing her and she was looking at me while I did things to her. I gradually went deeper and began fucking her in that position. I was pressing her boobs and fucking her at the same time. I pinched her nipples occasionally.“Fu-uh-uh-ck me,” she said. So I had to go harder. I grabbed her throat and fucked her really hard like that for 5-10 minutes.I got tired from standing and bending so I climbed on top of her. My balls slightly touched her stomach. I spat on my dick. The stranger knew I was ready for him.The hands began to remove my panties. I lifted my legs to make their removal easier. As they dropped to the kitchen floor, the back of my robe was lifted up and draped over my ass. I knew that I was about to get fucked and I knew that I wanted to get fucked. I gripped the counter before me to steady myself and I bent forward to shove my ass back farther.I felt the tip of the cock behind me being run up and down my pussy slit. It tormented me to feel it. She was smiling when she came in and I asked her why she was so happy. She sat down and said she found a new way to break up a boring drive home. She said traffic was bumper to bumper and while sitting there I started thinking about you showing off for cindy. She said at first I didn't realize what I was doing when I heard a truck horn honk. She said I looked over and there was a truck next to me and I noticed my hand was under my skirt playing. She said she moved it real fast then after.
