What if she ends up liking it and allows you to fuck her in the ass moving forward? I understand being upset about it. Just don’t end a marriage over it Before you talk about it and work through it.
Anal....that's just how it happened with us. Her and I tried a few times, never went well. Fast forward...we get into mfm with a guy we know....WAY out of our normal lives but we got more comfy each time. One night he just said "we're going to enjoy some anal". She just let him do it. He lubbed them both, went SLOW, she grunted loud and soon he was all the way in. He pumped maybe 10 slow full pumps then pulled out, she said WOW.
Since then anal has become part or our fun. There's been nights him and I have both fucked her butt hole.
Just her and I have a lot of good sex, often. Anal is always a part of a good love making session but never with a quick morning or afternoon romp.
That first time he did her back there I was like WTF? In my head I was pissed for days but I got over it. Now it's a huge turn on watching them do it.
Different situation....I can always get her off with oral. She never had an orgasm from me pumping her, said she'd never had one with any guy pumping her, all good.
We get into this with our friend, I'd say we'd been with him 10 or so times over about a year. Was more relaxing each time. One night he licked her and she got off, had happened befor. I fucked her for a few, he did her for a few, I went again and came in her, she gets REALLY turned on when we switch out. He started with her, he was on top really going at it getting ready to unload, her body got stiff, she stretched her legs straight down flat and came HARD, that got him off. It was the hottest thing I'd ever seen but in my head....how? Why? That too has become a regular part of our fun.
