Satisfying my extreme erotic fetishes, this blindfolded, busty, science-oriented girl is seduced by contrasting cosplay. (HSODA-123)

In the pharmacy department, I, a gloomy otaku, share a common hobby with Haruna, a girl in the physiology department: erotic manga! Today, we got into a lively conversation, discussing topics I absolutely couldn't talk about with other girls. I thought she was easier to get along with than a man, and that nothing more would happen between us… but then, a condom fell out of Haruna's bag! Although Haruna seemed flustered, she actually suggested, "Want to try a condom?"! We decided to go to her house, and when she said she wanted to try something, she changed into a completely different cosplay outfit! Intensely excited by their erotic manga-like attire, the two of us began having sex just like in an erotic manga! Having experienced the ultimate pleasure, the two of us couldn't stop!
