A bullied girl with a 92cm G-cup bust dresses up in cosplay and transforms into a sexy girl in both body and mind! Once she's transformed, the otaku presses her breasts against her, wanting her to fulfill his many extreme erotic fantasies, and even inserts his bare penis into her in a cowgirl position, accepting it. According to the poster, her large breasts make her look good in anime cosplay, and the strings digging into her breasts are erotic.
