Manabu has long been in love with his friend's mother, Yuka. After becoming an adult, he confesses but is quickly rejected, so he visits a mature-woman soapland hoping to lose his virginity to someone like her. The shop's number-one woman turns out to be Yuka herself. Worn down by his pleading, she reluctantly gives him his first sex. The overwhelming pleasure of sleeping with the woman he loves changes his life: he becomes a regular and later starts secretly fucking her at home as well.
