Lately, Yuki has been increasingly unsatisfied with her sex life with her husband and has been indulging in solo masturbation more often. One day, she catches her son-in-law, Atsushi, secretly masturbating at night. Immediately captivated by his overly muscular, large penis, Yuki decides to have sex with him "in place of her daughter who won't." From morning till night, she takes every opportunity to suck on Atsushi's large cock, making him ejaculate repeatedly. Atsushi, driven to the point where he can only think about his lower body, continues to be consumed by desire. *Please note that the content may vary depending on the distribution method.*
