"Which store should we go to?" Kentaro decides to go to a soapland with his friend Ryosuke for the first time in a while. "What, married women? There aren't even any pictures of their faces on the website." While Ryosuke chooses a casual store that caters to young girls, Kentaro pretends to be an expert by saying, "I'm more interested in technique than appearance," and goes into a married women's store that is rumored to be able to offer creampies... "Welcome, nice to meet you... Eh!?" "Hello... Wow! It's Ryosuke's aunt!" To his surprise, it is Ryosuke's mother, Ichika, who has known each other for a long time. The two of them have complicated expressions on their faces at the unexpected situation. "Hey, can we keep the fact that we met here a secret from Ryosuke?" Ichika is the first to break the silence.
