Satoru's crotch starts to itch. Unable to bear seeing him like this, his mother Kyouna lends him some delicate cream, but now Kyouna also starts to feel an itch in her crotch. She goes to Satoru's room to get the cream back, but unfortunately, he had already left. After searching, she somehow finds the delicate cream on her own and applies it to her crotch... The itching doesn't stop; instead, her body starts to sweat. Confused, Kyouna applies more of the cream...
