Yuka's husband was assigned overseas, her son rebelled, her frustration increased due to loneliness, and masturbation became a daily habit. One day, my son's friend, Makoto, came to play, injuring both of his hands. Yuka felt sorry for him, who could not even manage his daily life and take care of him. Unlike my rebellious son, one day when I felt the joy of serving in his honest response, Makoto got an erection while his body was being wiped. Afterwards, Yuka, who felt her body aching from his strong cock, could not bear it.
