Imouto Paradise 2 (Vol. 2): All to Myself—Losing My Virginity ❤ Momoka plays a motherly role, handling all the housework on her own, but she has been self-conscious about her lower body, which is beginning to fill out with the curves typical of a girl her age. Keiichi barges unceremoniously into his adolescent sister's room. He only came to borrow a mechanical pencil lead, but Momoka—mistaking his visit for a request for sex—starts taking off her skirt. Although she realizes her mistake when she sees Keiichi panicking, she doesn't stop. The reason? Ever since she stumbled upon an erotic magazine while cleaning Keiichi's room, she has been intensely curious about sex.
