It's been half a year since my father, who made a woman outside, left home. Yusuke was hurt by the appearance of his mother, Miyako, who behaved cheerfully without worrying about it. How can I cheer up my mother ... Yusuke was worried, but decided to see Miyako masturbating and sobbing. I will take the place of my dad. Yusuke hugs and caresses Miyako as a man. Miyako is confused, but when she finds out that Yusuke is serious, she relaxes her resistance.
