[Roboku] Mesugaki☆Mart (Bessatsu Comic Unreal Mesugaki Wakaraserare Haiboku Shasei Vol.2)

A bratty little demon girl working part-time at a convenience store has her stuffy manager completely at her mercy, and she keeps him there with a compromising photo on her phone. When he finally snaps and tries to discipline her smug attitude with a rough, hands-on lesson, she just giggles through every punishment, milking him warm and deep before stopping mid-act to watch him squirm. The power balance never tips back her boss's way — she rides him at her own leisure, teases how quickly he tires, and sweetly reminds her underling exactly who holds all the leverage.
