Living with my in-laws at their house, I've always been treated kindly by them, but lately my wife's attitude has grown distant. When I finally tried to initiate intimacy with her after a long time, she rejected me, absorbed in her video game. Frustrated, I headed to the living room when I noticed my stepmother's lingerie in the bathroom. Curious, I sniffed it and was overwhelmed by her scent, unconsciously beginning to stroke myself. Suddenly, my stepmother appeared, and I panicked, trying to hide my arousal. In the silence that followed, she whispered, "You were in the middle of something, weren't you?" and gently touched my crotch. My softened member quickly hardened again as she said, "This will be our secret, just for today," before burying her face into me and slowly starting to suck.
