Welcome to Succubus High Vol. 2
Inubou Takeru is doing his best to fit in with his clasmates, but when he's the only male at a school full of succubi, blending in is impossible. His classmates single him out for humiliating lessons on male biology and behavior, and he's running out of excuses to tell his sister and the girl he likes. The succubi want to learn all about boys, and Takeru's only choice isn't much of one -- play along or be expelled!
