Inchlings are absolutely obsessed with exotic animal husbandry due to depending upon it for their existence. Try prepping actual bulls at an inch tall. Because of this and her inability to fuck you directly, she would make sure you fucked and impregnated every other girl in Gensokyo to raise your offspring, and she would be PROUD of it.
Imagine her cheering you on like a soccer mom as you dicked Ran and Chen at the same time, all three of you silently staring at the ceiling because you're all doing it under duress!
Shimmy forcing you hard again when Chen says she doesn't want a brother!
Shimmy making it worse by saying she'll be looking after her own child!
Also she would travel in your pants for the warmth and smell and if you actually talked with other women she'd be having human fries for dinner. Very wholesome!
