Pavlov's Lover
Complete | tsushiko | 2000 released
the only good thing i like bout this is the biting stuff (yeah that's my fetish), other than that the seme's age (he's a highschooler) is kinda a turn off for me, and the story feels a lil rush n incomplete idk maybe will reread for the biting parts
