In the days of deep research, the idol of the engineering department, 'Haruka-chan,' is known for being pure and intelligent... or so it seems. However, she can't be satisfied unless she pursues everything to the extreme, and she's incredibly greedy when it comes to sex! 'I need to have sex at least 3 times a day' 'I've watched over 1000 adult videos!' Her favorite penis shapes, the best angles for insertion, etc. — her conversations are super perverted! She won't be satisfied unless she experiences everything firsthand and challenges herself with her first-ever raw sex... It feels even better than imagined, and she even allows internal ejaculation! The sexual desires of a science girl are no joke!
