Accidental Ass To Mouth

This is not a big concession and it happened last night. I was assfucking my wife, which is our usual go to and it gets her off easily. Last night however it was starting to hurt her a bit. She is also against going from ass to pussy cause no matter how clean it can bring UTIs and no one wants to stop sex to clean their cock to continue. So I lid next to her and she was finishing me up jacking me off and I was making out while she was doing it. I told her I was going to cum and with thinking she instinctively and quickly put her head down and mouth over my cock to tame the cum in her mouth. After she had sucked the soul out of me I reminded her about 5 minutes prior to I had all of it up her ass. She didn’t seem disgusted and was like “oh well that wasn’t too bad at all then”. So I’m hoping to try and get more of it in the future, it was sexy as fuck.
