[Tamachi Yuki] Wakarase Hatsukoi Control Ch. 1-2 [bored_one28] [Ongoing]

A teacher's after-school "research assistance" turns his students into collared pets, and bratty twintailed Miku is the next to be broken in. Already trained and dripping, Haru eagerly helps initiate her classmate—guiding Miku's tiny breasts and skinny legs through her first taste of submission while sensei promises to fill her to the brim until she craves his semen too. Between mind-controlled kisses, semen-filled panties, and the pledge of deeper lessons tomorrow, the question is how long Miku can keep up her bratty act before the collar tightens for good.
