Haruka-chan, an idol from the Faculty of Engineering who shines a light on her days of research, is a pure and intelligent girl... or so you might think, but she's also extremely greedy for sex, with a personality that won't be satisfied unless she gets to the bottom of everything! "I can't stand it if I don't have sex at least three times a day," "I've seen over 1,000 adult videos!" She talks about her favorite penis shape, the best insertion angle, and more, and is a super pervert! She won't be satisfied until she's experienced everything, so she tries raw sex for the first time in her life... It feels better than she could have ever imagined, and she even allows herself to be creampied! The sex drive of this science girl is incredible!
