[Etori Yuuya] Please show me your guts

A dojo student named Takuya trades his flagging spirit for a mind control app on his phone and flips the power dynamic, ordering his sweaty, athletic teacher to show him some real 'guts.' Stripped of his dignity and squeezed into a frilly maid outfit with a collar and leash, the tomgirl sensei endures merciless enema training that swells his stomach into a huge, trembling, heart-marked bulge while his small, giggling pupil inspects the results like a strict instructor. Even after a spectacular, splattering release leaves him dazed, drooling, and dripping across the floor, the cheerful little domme demands even more guidance.
