When Kenichi, who was depressed by her, came back, his aunt Mako was there. The bath at her house was broken, so she was going to be taken care of for a while. But now the shock of being dumped fills her head. When I leave the story and take a bath, Mako enters without knowing it. She is surprised to see Kenichi crying, and Mako gives her a bath to heal her, and Kenichi gets an erection. The two crossed the line after she pulled out with a blowjob as an apology.
