My mother-in-law came to Tokyo for the first time in a while and stayed at our house. She is the type of woman who embodies the 'mom' archetype, with a plump figure, completely opposite from my wife. I had some inappropriate thoughts about her, and I was eagerly awaiting this opportunity. My mother-in-law's face was slightly flushed after her bath, looking quite cute. I quietly made my way to the bathroom and rummaged through her underwear. As I cautiously unfolded it and smelled it, the scent of my mother-in-law stimulated my groin. While I was engrossed in perverted self-pleasure, my mother-in-law unexpectedly showed up.
