A commercial series by the doujin circle [Second Generation Spit Drinking Uncle] that pursues the dark side of cosplayers. Ayaka-chan is a popular girl, but she watches a lot of anime on subscription services and has entered the cosplay world! Perhaps because she is a popular girl and usually only has healthy sex like sports, she is initially reluctant and confused by the sneaky and clingy play of the otakus, but she gradually becomes captivated and her 103cm huge breasts shake as she orgasms over and over again, which is spectacular and extremely erotic!
