Mii-chan is a famous cosplayer in the field. This time, we heard rumors about her and decided to do an in-depth interview. At an event, only familiar fans gather at the offline meetup, and in exchange for a high participation fee, they're allowed to have sex! With everyone's permission, we filmed the whole thing. This is a documentary AV production where you can enjoy Mii-chan's unbelievably huge J-cup breasts!
