GHNU-083 A plump witch warrior hunts demons and falls to a tentacle trap

A plump beauty witch in her thirties teaches at a night school by day. She is secretly a galaxy investigator chasing the space demon king Delville, who has brainwashed her students. Delville uses a tentacle whip on her big breasts, finds her overripe body is her weak point, and sexually assaults her. She climaxes many times and ends up as a meat servant in a bad end.
