I've been divorced from my daughter's mother for a few years. It was amicable. Just didn't have anything in common anymore after our last kid left home.
I never had a cuckold fantasy until I discovered my 24 year old daughter had that kind of relationship with her somewhat older husband. They still don't know I know.
This last July I saw my daughter with another guy, but she didn't see me. I was driving on a rural road, and I saw my daughter's car in front of a house. I didn't know who lived there. As I came closer, I saw her by the side of the house near an above ground pool. She's petite, and she was in the arms of this tall man with her legs up and around his waist. They were kissing and she was stark naked. Both parts of her bikini were lying on the deck. I was angry and worried that she was going to ruin a good marriage. She was always wild, but I thought she had settled down. I just kept driving and pretended I didn't see it, but I don't deny that later on the memory of it flashed through my mind and I was a little excited by it. Mostly though, I tried to forget it.
About three weeks after that my HVAC went kaput one really hot evening and I called my daughter to see if I could stay the night at her house. She answered her phone and said she was out, but no problem, her husband was home and that I should just go on over there. I did and her husband was glad to see me. We always got along well, and I asked when my daughter would be home. He said she was having a girl's night out, and it would probably be late. My memory flashed to what I saw before, and I thought to myself she might be with another guy.
It was getting late, I was tired, and I told my son in law I was going to bed. From my bedroom window I could see their driveway, and I wasn't quite asleep when my daughter pulled in. I got up and saw that their security light lit her up as she walked to the door. Her hair was disheveled, and she had on a short black tube dress that was showing the bottoms of her bare ass cheeks and just barely covering her nipples up top, and she was carrying her high heels. She looked like she'd just had sex. I was thinking, christ, doesn't she think about changing clothes and fixing herself up before she comes home so her husband doesn't get suspicious? Is she trying to ruin her marriage?
I couldn't resist sneaking down the hall. There's a fair size mirror on their living room wall and I could see them reflected in it. As soon as my daughter walked in she asked about me, and hubby said I was fine and must be asleep by now. She said we better stay here because Dad's room is next to ours and he might hear. Right afterward, her husband dropped to his knees and jerked her dress up. He said, "Where's your thong?" She said, "In my car. You tore the last one trying to get at me." He started licking her thighs and worked his way up. She giggled and said, "You're so pussy whipped, baby, you know that?" He moaned. She threw her head back and said, "Well, go ahead, get it honey. Get all of Chris's sperm. You better, unless you want to start buying me maternity clothes."
I was flabbergasted. My jaw was probably on the floor. I'd heard about this kind of kink, but never in a million years did I think my little girl was involved. By her words, she sounded like they were at a very advanced level. Hubby just moaned again and looked like he was trying to crawl up inside her. She said, "You're wasting your time. Chris shoots farther in me than you ever could. It's up there so far it'll never come down. You just better hope I don't get pregnant."
He ate her out a little longer, then he got up and started to take off his clothes. She said, "Oh, you're going to tickle me with that little thing you've got? I hope I can feel you. I've been touched tonight in places you'll never reach."
She let him pull her dress off and there was nothing at all underneath. He puts her on her knees and fucks her pussy from behind. She starts giggling again and teasing him, and the more she belittles his cock, the harder he fucks her. He comes quickly and she says, really snarky, "My god, I had a virgin once that lasted longer than you!"
They looked like they were getting ready to leave the room so I sneaked back down the hall. When I got to my room I found I was harder than I'd been in years. Really hard for a guy my age. I couldn't process everything I'd heard and seen, but I started jacking off. I imagined my daughter making fun of me and telling me that her husband and I were her houseboys. I came in no time myself.
It's been three months and I'm still trying to process it. Those two act like a normal, happy, almost boring couple in everyday life. I'd never have guessed, and I'd never have guessed I'd be this affected by it. Part of me would like to let them know I know, but of course that's not a good idea.
FUCK MY WIFE!
