ROE-131 Being aroused when seeing my son's penis

Her daughter has reached adulthood, and Yuka, who has begun to get tired of her normal life, secretly wishes to return to being a woman again. One day, I received advice from my daughter's boyfriend, Yusuke. While helping him overcome premature ejaculation in the process, the libido hidden in Yuka's chest is violently shaken. The two gradually escalated and continued to practice to overcome premature ejaculation with various stages such as blowjob, nipple torture and licking the whole body instead of just using their hands.
