A while back my girl and I began a new direction in our relationship... she basically takes it from who she wants when she wants lol!

Last evening (Christmas Eve), I returned home from business meetings. Yes, I had missed dinner and it was almost Christmas... but it seemed justifiable considering the business outcome that evening achieved. All parties want the business closed before the Christmas break.

I drove the car into the garage excited to share the great news, I exited and walked in the house, as I did, I could hear noises coming from upstairs. I assumed her "boy toy" was visiting giving his Christmas present to her.

I made myself a drink, then walked up stairs to change and take a look. Yes, I enjoyed seeing them sometimes. Why not on Christmas eve masturbate outside the door while watching.

As I reached the top of the stairs and turned, I noticed the noises coming from another bedroom. I listed and walked toward the open door. There I saw my girl, legs up, moaning, with someone on top of her I did not expect. It was her son (not mine), going hard on her. He is 24, good looking, well hung (I had noticed when he was wearing sports shorts at times). I was shocked at what I was seeing. I walked back down stairs and finished my drink. They took another 20 odd minutes to finish.

After about 30 mins, she noticed I was home with the noises downstairs and came to see me. As she approached, I asked "What was that about? What do you think you are doing?". She said to me "You were not here, Jaimison could not come over, and I was in need!" As she stood there about to pour a drink, her night gown open exposing her breasts and body. I looked and noticed there was cum dripping down her leg and out her pussy, dripping on the floor. I said "You let him cum inside you!". She smiled and laughed...then said "why not! Relax, you've been fucking me before with his cum in me!" I stood there not sure what to say. As I did, she came over and rubbed my and squeezed my crutch. She said "Your not hard!?" I said to her "I don't think what you are doing is a good idea. It needs to stop". She laughed and told me to calm down. With that she unzipped my suit pants, pulled out my cock and started sucking my cock. Always the best BJ I had experienced, I never refused. She pushed me backward onto the sofa, continuing to suck my cock. As I lay there enjoying her sucking, she stood up, opened he night gown and straddled me on the sofa. Still dripping a little, she sat down on my cock and started moving up and down. She was very wet, but also very loose. As she went up and down, she said "He is so much bigger than you. Fuck me with your little cock! Cum!" It was humiliating but felt so good I was enjoying it so much. It didn't take long this time, I moaned loud and cum inside her. She lowered and remained on top. Leaning down and kissing me on the lips.

After we had finished, I made drinks for us both. We stood talking about the day. As we did, her son came down stairs. It was an uncomfortable conversation knowing what had happened. He talked to us like nothing had happened. He was unaware, I had seen them and now knew what had been happening with them for quite a while. I decided to let it go, enjoy Christmas day as a family as her daughter and husband were coming to stay over the holidays with us.
