The phrase 'otaku girl with big breasts' sounds kind of erotic. The plan is to intrude on such a girl's home and engage in lewd activities. Upon visiting, it turns out to be a spacious and luxurious apartment. It seems like a wealthy family, too large for a single person, but she decorates the walls with cosplay costumes and anime posters. Talking to her, she seems like a lady? Maybe it's a reaction, but she has released erotic photo books at the age of 15. This is intense! Is it okay? With her cute face, she definitely has a naughty side. She confidently wishes to appear in AV and reportedly likes being filmed. Following this vibe, the activities range from a sensual check to semen gulping, mixed bathing with an otaku man, private intimate moments, internal filming, and finally, group sex with ejaculation. 'Mikoto-chan' shakes her H-cup breasts in a cosplay outfit and goes wild.
