Tomomi has always done her best to ensure her daughter and son-in-law live happily together. Lately, however, she's noticed her daughter growing increasingly cold toward her husband, which worries her deeply. Just today, when her son-in-law casually praised one of Tomomi's home-cooked dishes, her daughter became sullen, and the atmosphere turned tense. Late that night, Tomomi headed to the kitchen and found her son-in-law sitting there, looking dejected. When she asked, he admitted his problem wasn't about food—he whispered the words "sexless marriage." Gathering her courage, Tomomi said, "I'm sorry... just for tonight, I'll make an exception," and began stroking his crotch to comfort him. A few days later, while Tomomi was asleep, her son-in-law snuck into her room under cover of darkness. She struggled desperately at first, but overwhelmed by his strength—and especially by his thick, powerful cock—she was shocked to find herself aroused beyond control. The pleasure she hadn't felt since her husband's passing surged through her, awakening desires she thought long gone. Still, she clung to her pride as a stepmother. Yet consumed by her son-in-law's insatiable lust, and later even fantasizing about his cock while alone, she found herself secretly touching her own wet slit.
