Newly appointed teacher Ai returns to her alma mater, walking through the school building immersed in nostalgia, when she stumbles upon the "reflection room" hidden in her old classroom. The space retains the same eerie atmosphere as in the past, and here she unexpectedly finds herself trapped. Bound with rope, she is forced into repeated blowjobs, made to cum each time, and tormented with an electric vibrator over and over. Her mouth drips with semen, forced to swallow every drop—an ultimate pleasure in degradation. Even during classroom lessons, her body becomes consumed by lust, repeatedly drenched in cum until completely covered from head to toe.
