(Oh no... what should I do?) Ryota fell in love at first sight with his mother's beautiful friend, Yukino. (I wasn't told she was this beautiful!) Amazing huge breasts that you wouldn't imagine from her slender waist with a curve. Ryota, who has no experience with women, involuntarily swallows his saliva at her exquisite body, which is too stimulating. Ryota, who can't stop worrying about Yukino, peeks at Yukino's bathing figure, carried away by his surging desire... but unfortunately, he is noticed.
