My wife let [M]e [F]inish in her tight asshole

A little backstory, my wife and I are in our early 30s, have been married for 10 years, and have been having the best sex of our lives recently. I mean, it has never been bad, but lately our sessions have been especially intense and passionate. She has been on a health kick, losing a lot of weight recently, and her libido has skyrocketed. No complaints here. We’ve even started sharing pictures here on reddit, which has made for some extra fun times in the bedroom as well. Anyway….

When my wife drinks and is horny, she likes to make it a cat and mouse game. We had put the kids to bed, and were both a few drinks in, watching TV, letting the evening wind down. As she was sitting beside me on the couch with a blanket over her and her feet reclined, I noticed her hips starting to rock back and forth, and heard a few subtle moaning sounds under her breath. While my initial instinct was to pull the blanket off and get to it, I knew pretending to ignore it would yield better results. After a couple minutes of me being blissfully “unaware” of my surroundings, I notice that the blanket was no longer covering her shirt, and looked over to see her pale breasts exposed, glowing in the soft light from the TV. She then guided my hand over to them, and with her other hand reached into the front slit of my boxers and started stroking my cock, all the while continuing to watch TV as if nothing was amiss. This went on until the show we were watching ended, when she promptly walked into the bedroom without saying a word. I obviously followed.
