My wife gets very wet. This has led to the occasional oops moment when the head of my cock has slipped into her ass. To me it has always felt like her ass was made for fucking due to the ease of me slipping in there. Unfortunately she does not agree and she usually shoots off me like a bottle rocket.

The first time is probably the most memorable for me still. We had gone to bed (to sleep) and she was just wearing a t shirt. As I was spooning her, my cock just naturally nestled into her bare ass crack. Of course I was soon hard and she laughed and said “you can just take care of yourself tonight, I'm tired.”
So I was going to crank one out quick but then decided well there was a bare ass here. I started rubbing the head of my cock back and forth between her cheeks. It was feeling good and I would have been happy to finish and go to sleep but my wife was starting to get turned on now also. She shifted a bit so now my head could also brush along her pussy. I continued stroking along her ass to her pussy and back. When my cock parted her lips she was soaked, and as I kept rubbing it carried her juices up to her ass crack. She was soon quite slippery everywhere. She was soon pressing harder into me and I into her, including brushing right over her asshole. It was feeling so good I pressed a little harder on the next stroke and sure enough my head slipped right in. I've never seen her move so quick as she put space between her and my cock. She rolled over to face me and said “not there please” as she then pulled me on top of her for some good old missionary.

She has on a few occasions genuinely given it a try. Plenty of fore play, lube, talking and taking it slow but with basically the same results as the accidental moments. Once the head slips in, before trying to go deeper she asks me to take it out. She has said she knows it is in her head and she apologizes but it is not really a big deal to me as everything else she does for me is great.
