[PitaPita (Pita)] Doll Turning Collar - Female Magician [DRTL]

A talented witch makes her living crafting magic tools, but the mana-extracting device she sells to a smirking client comes with a price she never agreed to pay — soon she's the one collared and gagged, pinned down and violated with the very toy designed to drain magical beasts. When he carelessly leaves her alone, she makes a desperate crawl for freedom, only for the cursed collar to seize her body mid-escape and steal her movement inch by inch. Bound spread-eagle in steel restraints, blindfolded, and stuffed full by a relentless intrusion, the proud magician is reduced to a living doll at the mercy of her captor's twisted hobby.
