I went to a soapland to graduate from virginity and fell in love for the first time in my life. Aimi-san, who responded to my confession, a person who is beautiful, busty, and kind. It's like a dream to be able to date such a wonderful person. But... are they doing such things and those things with other customers besides me...? The first SEX, the first lover, the first jealousy. And... the first break-up. The closer we get, the more our feelings for each other clash. The more I like her, the more painful it becomes, my overly erotic first love with the soapland girl.
