[Akairo] Sensei-tachi no Houkago (COMIC Megastore Alpha 2019-01)

When Class 2-4 posts the lowest scores in the school, Nagi Sensei learns that faculty 'punishments' come with a collar and zero mercy—bent over desks while suited colleagues cycle through her mouth and pussy in relentless rotation. Her heavy breasts become playthings for paizuri and groping hands, her protests of 'please stop' swallowed by the next cock queued up for her throat. What begins as reluctant duty melts into ahegao-soaked surrender as load after load leaves her gaping, dripping, and utterly spent.
