My wife of 10 years was getting ready to spend the day shopping with her girlfriend. She was running late and didn't have time to take a shower. We figured out that it had been a few days since her last shower, but her vagina passed the sniff test. Then she told me that since she has started gaining weight it was getting harder for her to properly wipe her ass. I immediately offered to inspect her backside. She got on all fours on the bed with her ass cheeks spread. This was not an easy task for a woman of close to 400 pounds.
While I was removing her pajama bottoms she had to wiggle and jiggle so that I could get them down all of the way. The huge areas of blubber on her shapely ass jiggled wildly as she moved. I felt instant blood flow to my penis. The bulge in my pants grew larger as I began my visual inspection between her gorgeous cheeks. My eyes were immediately drawn to her beautiful anus. If you added up the amount of time I had spent looking at her asshole it would certainly be days. Despite being familiar with every fold and dimple in that perfect hole between her enormous ass cheeks, I'm always blown away by how absolutely beautiful that opening in her body really is. I'm too focused on her butthole to notice my rock hard erection.
I start to inspect her body and don't see any major problems. Upon closer inspection I can see tiny toilet paper balls in the folds of her anus and between her butt cheeks on either side. I put my face right between her supersized cheeks and sniff her asshole. Definitely not shower fresh, but the way her not shower fresh asshole smells really turns me on. My penis is rock hard and throbbing in my pants. I tell my wife that it smelled a little dirty, but looks okay. My wife said that I could take a moment to clean her backside since she had put in so much effort to getting in this position. I hesitated for a split second because she was really not fresh down there, but decided to just go for it.
