Due to a business trip, I couldn't secure a hotel reservation and ended up staying at my son and daughter-in-law's place. My son's wife, Kanae, is kind and has a beautiful smile, and I find myself deeply attracted to her big, shapely ass. Overcome by an uncontrollable impulse, I start fantasizing about her in lewd, erotic ways. Before I know it, reality blurs—she's acting provocatively, deliberately showing off her ass, leaving me breathless with desire.
