the aunt of minami's has quietly seduced me in his underwear.

You've always been conscious of your son's friend Kouta as a man. At last, one day, the feeling overflowing with cumulative emotions became unbearable. It’s a more flashy thing to be able to change into your underwear when you say “here” and finally succeeds in the temptation of Kouta. and first of all, we're going to do a little research... i'm going to smash the sperm with a nasty whistling. Kouta jumped out of the house from awkwardness and ran away. Don't notice that you accidentally forgot your phone on the spot. On the next day, Kouta visits the Nanjo family again to receive forgotten mobile phones. Then he wore a lingerie, which was even more irritating and distressing, and waited for Cowta.
