Living as a son-in-law in my wife's parents' home, both my wife and mother-in-law have always treated me kindly. However, my sex life with my wife has been nonexistent for the past six months, and I'd reached my limit. One night, noticing my wife seemed to be in a good mood, I tentatively made a move, but she was taken aback by the sudden advance and turned me down. Unable to sleep, I spent time alone in the living room when my mother-in-law woke up and came downstairs. Sensing something was off, she noticed my presence and gently asked what was wrong. I ended up confessing about our sexless marriage, and she looked at me with a faintly sorrowful expression before softly suggesting that, just for tonight, she'd make an exception for me. Responding to her words, she gently stroked my crotch and took me into her mouth. Her slow, wet blowjob was even more incredible than I'd imagined, and I quickly reached climax. Feeling relieved, I finally fell asleep—but couldn't stop thinking about what had happened with my mother-in-law. The next day, after confirming my wife had left the house, I gave in to my urges and threw myself at my mother-in-law.
