[Marushamo] TINIFICATION SEX

The black‑and‑white manga follows a male protagonist who suddenly shrinks to a few centimeters (tinification) and is placed in a facility with other shrunken males; later he is shown in a large, cavernous setting interacting with a giantess female who treats his tiny body as a sexual object, with panels depicting classroom scenes, an exterior building, close‑ups of the giantess's massive body parts, and explicit actions involving his miniature form.
