After the divorce my father resigned from the diplomatic service and the military and moved back to the States. My mom stayed on. We had to give up ou... bigger apartment and were assigned to a smaller unit with two bedrooms. Mom and I shared the master's bedroom. She needed the smaller room as her study where she also kept her big safe. Only we and the tenants next door had eccess to the small roof-top garden. One of mom's favourite pastimes was sunbathing on the roof-top, often naked. She had. As I did so the unmistakable sound of our bed creaking came from the bedroom. It was clear from the rhythm that Mike and Allie were making love, and rather strenuously at that.I waited what I thought was 15 minutes before getting on the shower. I must have guessed right, because the shower washed all my body hair away. Here I was, getting my body ready for further feminization, and my wife was fucking her lover in our bed. I still couldn't answer the question in my head; was this what I had. Mr. Troy kept apologizing until mom said “it’s okay Bob, that’s just one of the hazards of the job”. Mom looked at me and asked “could you take this wash water and clean Bob up and then get him dressed again”. I told her I would and I was glad when she left because, I had a huge hardon myself from watching another mans cock shoot cum all over my own sweet, innocent mom.After my mom went home, I cleaned up all of the cum from Mr. Troy’s body and started washing his semi-hard cock. He said “I’m. It was very wet."Well, you enjoy that, uhm," I said to her. "Yes, Master, Thank you, Master." she said."You have been a good slut. You need a reward," I said to her and before I had finished talking, I gave her pussy a hard blow with my flat hand. Her body twitched in the air and she gave me a little scream. But only after the first blow. Perhaps the little scream was a scream of surprise. I continued to let the slaps fall on her pussy. She flinched slightly at every stroke, but now without.
