I'm married, living with my wife and her mother, and I'm a househusband. I get along well with my wife, but she doesn't seem to like intimate acts, and we haven't had sex in a year. I tried to ask her for sex after a long time, but she said she wasn't in the mood. Feeling a little annoyed, I headed to the living room, where my mother-in-law asked me what was wrong. She said, "We can just talk about it, but we're not family," and I hesitated for a moment, but then I told her I hadn't had sex with my wife. Surprised, my mother-in-law looked at me and said, "I'm sorry, but I'm your daughter. If you don't mind, would you like me to make you feel better?" My mother-in-law has fair skin and plump breasts. I'd always wanted to fondle her breasts from behind, but when she told me she'd make me feel better, I froze. She smiled, licked my nipples, and grabbed my erect cock. She told me not to tell my daughter, but her blowjob was so satisfying, I came in no time. I certainly felt relieved, but I still felt unsatisfied and was overcome with the urge to play a prank on my stepmother.
