I found this on some forum. i feel bad for the wife but i was turned on by the story:
"I caught my husband and my son having sex...
I am a 52 year old woman who has been married to a man I thought loved me for nearly 15 years. We have had a happy if somewhat uneventful marriage. We met on a blind date and at first we didn't click but later meetings we found we had a lot more in common. We got hitched about a year later and that's when we had our daughter and the only child between us. My son from a previous marriage was well into his 20s when my husband and I got married, and was there for everything. He supported our union, was there when I gave birth to his baby sister, and was even happy to call my husband "Dad" despite the fact that he was still very close with his biological father. Still, I thought it was wonderful that my son and my husband had started a strong friendship.
If only I knew sooner what was really going on. About two months ago I came home early from work. My car didn't want to start so I got a girlfriend from work to drive me home. I noticed that my husband's car and my son's car were both in the driveway. My son usually visited the house every other day to either drop off some food from his job or chew the fat with my husband so I didn't think it was strange. But as I got to the door and opened it I could hear nothing but the loud blaring of Patti on the stereo in the living room but no sign of my husband or son. I was shocked however by what I smelled: reefer, in the air, stinking up my house. I was mad and made my way to the closed door to our bedroom. But my walk slowed when I could hear the moaning. It sounded like my son, moaning loudly behind the door. And I could hear the familar squeak of my bed when my husband and I made love.
I tell you I was so angry I was sick. But my assumptions would all be erased when I opened the door and found that it was my husband who was having sex with my son. And I stood there in the door looking at them go at it until they finally noticed me. They were higher than kites, eyes red, stupid grins all over their faces, my husband on top of my son, holding him like he held me when we did that. I couldn't say a word and neither did they. They just looked at me then started again what they were doing as if I wasn't even there.
And I walked out. I closed the door, took both their keys and took my husband's car and just drove for the rest of that evening. When I got back, my husband and son were still at home, in the living room, obviously down from their high. When I walked in they just looked at me. Neither of them said nothing and I didn't either. We just looked at each other. I sat my son's car keys down and told him to leave. And he did just that without a word.
I've filed for divorce from my husband. He says he wants to work it out but I just don't think I can. My son and I haven't spoken since then as well. Neither one of us have made an attempt and last I know he was planning to move closer to his father in Florida.
My life is a mess but I don't want to tell any of my friends. I feel that all I have is my daughter and I can't tell her what I saw her father and brother doing. All she knows is that her parents are in a bad place and she can't do anything about it. The truth just hurts to talk about period. It's all that I can do to simply talk about it on this site to a bunch of strangers. Don't really know why I'm doing this though. Maybe you all can give me answers or guidance where I've found none. Maybe I just needed to get it off my chest. Thank you for reading."
Get hard when I think about it.
