Anon, reaching out for some help.
Looking for a hentai comic, basic story is human male student gets placed in a school for partially-animal students. Multiple issues made, i'll give plot summaries of the ones i remmeber:
1. principal makes a potion that gives her a dick, gives him a vagina
2. catgirl student crushes on human male, goes into heat, gets plowed by part-bull student.
Don't know if this is too vague, but i will give you my first born for the comic title.
[Yonekura Kengo] Pink Sniper, there's also a sequel Pink Sniper Maniax
