[OYC-052] In return for sweets and shoujo manga, I play naughty pranks on her! My younger sister, who is in college, would bring her friends (cute Lolita girls) over to my house, so I would invite them into my room while she was gone, and in return for giving my sister's friends their favorite 'sweets' and 'girlie manga', I would do naughty pranks on them. In return, I was allowed to play naughty pranks on her.
