Doutei Otoko To Toramimi Onna (“Virgin Boy and the Tiger Eared Girl”) [English], by Arai Kei (Also Known As Kansai Orange)

Mixed feelings, yeah. That’s the word.

Graphically ? That was astounding, the feeling, the quality, the fine details of hand-drawn comics, with the subtle facial expressions, those beautiful shades, all those little details, and the girl’s generous body, her confident, teasing eyes, she was a mystery that could only be partly solved…
Scenario-wise ? Not everybody will like second hands. The male hero had a kinda idealized image of the student council female president, so when he finds she’s a slutty sex hound and made him his next prey (as the previous victim just finished creampying her), he accepts whatever she asks (becoming his pet) in exchange of losing his virginity.

EDIT: this story is now part of a complete volume, called Houkago Hinitiation. You can view it in two versions, in its full-colour version (but with hideous censorship) or in its grayscale tank version (still with heavy censorship, but not “OH MY GOD THIS IS ATROCIOUS” levels of censorship, still ).
