Описание: "Hey! Don''t jack off with my underwear!" "Fine, then can we jack off with you?" "Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaat" In an 8-person family with no mother in sight, it''s up to the big sister to take care of the men. But they''ve all got a bit of a problem expressing their sexual sides in a healthy way... So hey, why not make that another of big sister''s jobs, too? It was only a little while ago that she was in the bath with all of them, right? It''s not weird if she helps out just a little. Okay, it''s a little weird, but if it''s for the family, she''ll do it... even if it means losing her virginity!
[Character] Kyouko Osugi, the eldest daughter. The Osugi family is BIG -- Kyouko, her dad, and six younger brothers, to be exact. To a more old-fashioned mind, that means that it''s up to Kyouko to do all the housework and caretaking for the men, and she''s great at her job. She''s also got a body to die for and is completely boyfriend-free. Then one day, she catches her little brothers doing something dirty with her underwear... and life at home changes into something unbelievable!
