I went to a soapland hoping to lose my virginity, and fell in love for the first time in my life. Yuu-san responded to my confession, even though I'm not popular with women. She's beautiful, has big breasts, and is kind; it's like a dream to be dating such a wonderful person. But... I wonder if she does this and that to other customers too... My first sex, my first lover, and... my first breakup. The closer we get, the more our feelings for each other drift apart. The more I like her, the more painful it becomes, and my erotic first love.
