HILARIOUS YAOI

I didn't read it on here, I read it in Mangahere a while back,..but forgot the title. A teen does a demon summoning ritual to get laid, he has in mind a demon girl but then finds out he summoned a moe demon boy. It's hilarious they dont actually do it until the end but the demon boy follows the boy to his school and becomes a student and all that. please help, the demon boy has little demon horns from what I remember and has a tail(?) I think, please help!
