MIDV-806 NTR: My Otaku friend who helped me out at the event praised my lewd costume, so I had sex with her in a cosplay costume and creampied her in a love hotel. Ibuki Aoi

Synopsis

On the way home after the end of the Summer Comiket, a female cosplayer and a male otaku who was helping out at the event ended up connecting. The cute and reasonably popular busty cosplayer (her lewd costumes that reveal her crotch are also a part of her popularity) shared the same interests in anime and games, so they became good friends and helped each other out at the booth at the Summer Comiket. She already had a boyfriend, so it wasn't supposed to develop into that kind of relationship, but the cosplayer and the male otaku ended up in a hotel room together, a secret NTR experience that the boyfriend didn't know about. Usually, he just watches her in cosplay from the sidelines... but their bodies matched so well that he ended up cumming inside her over and over again.
