(Oh no...what should I do?) Ryota falls in love at first sight with his mother's beautiful best friend, Yukino. - (Because I've never heard that she's this beautiful.) She has stunning big breasts that you wouldn't imagine from her slender waist. - Ryota, who has no experience with women, can't help but swallow his saliva as the exquisite body is too stimulating. - Ryota can't help but worry about Yukino, and as he is carried away by his rising desire, he takes a peek at Yukino's bathing form...but unfortunately, he is noticed.
