Years after losing her husband, Honoka had grown accustomed to living alone when her daughter and son-in-law invited her to move in with them. One night, she accidentally witnessed her son-in-law masturbating. The sight of a man's erect penis, powerfully ejaculating, captivated her. A few days later, while her daughter was out, Honoka went to collect laundry and entered the couple's bedroom. There, she found her son-in-law napping. As she covered him with a blanket, her eyes were drawn to the bulge in his groin, clearly stirring even through his pants. Compelled by instinct, she gently touched him over the fabric. Feeling it thicken and rise beneath her fingers, her composure wavered. She pulled down his pants and trembled as she reached for his exposed cock, softly licking it with her tongue. Reacting with a twitch, it excited her further. She took it into her mouth, sucking fervently. As her son-in-law shuddered in climax, she blissfully cleaned up the ejaculate before quietly leaving the room, deeply affected by the experience.
