Dahlia is home alone when she spots an intruder at her window. The masked figure disappears, and she assumes it's just a bad dream. Dahlia decides to watch TV to distract herself, but her screen glitches and turns into a spiral. The intruder sneaks up behind her and makes her watch the screen, melting her mind away before fucking her.

Villainous Katana has created a secret formula that gave her a cock that bimbofies anyone who encounters it! She lures her arch-nemesis, SuperDahlia, to bring her down once and for all. SuperDahlia is surprised by Katana's new cock, but tries not be distracted as she attacks Katana. However, Katana's cock is already taking control and Dahlia is too weak to fight!

She falls to her knees, face to face with the magical cock. She feels her brain slipping away and her body begin to change, and before she can resist, Katana shoves the cock in her mouth. Dahlia's brain is instantly sapped and she begins to suck mindlessly.

Katana cums in Dahlia's mouth, which briefly startles her out of her trance. It's too late however, and her body has already begun to change. She grows long pink nails and her hair turns blonde. She whimpers and begs to be turned back as her tits grow so big they burst through her costume! She tries to fight Katana again but is easily subdued. Katana brings her to the bedroom and easily throws her on the bed. Dahlia is dazed and bimbofied as Katana fucks her and cums in her, filling her with a potent dose of the transformative cum.

Dahlia goes completely mindless as Katana gloats. Her tits grow to an enormous size and her brain is permanently erased. She is now just a brainless bimbo pet for Katana.

On the way to visit her granny, Dahlia runs into a big bad wolf in the woods. While she talks about her encounter in the woods, she notices that her granny looks a little different. Granny's hands, ears, and eyes look bigger. Before she can resist, Dahlia gets tricked by the wolf! With Dahlia under her spell, the wolf decides that she wants to make Dahlia her personal slut. She begins her training, deepening her power as she fucks Dahlia's mind away.

Dahlia is a trick-or-treater dressed as a cow. She knocks on a door, and is told that they are out of candy but have some in the house. Dahlia enters the home, only to get tricked with a cock in her face! The cock sways back and forth as Dahlia's thoughts melt away. She starts worshipping it, which slowly turns her into a cock hungry hucow.

Katana está completamente amordaçada com uma mordaça de bola coberta de fita de microespuma. Ela está amarrada de joelhos com fita adesiva. Dahlia beija, lambe e acaricia sensualmente a mordaça de fita, admirando como ela realça os lábios de Katana e abafa seus gemidos.

Dahlia vai ver o fabricante de marionetes Katana e confessa seu maior desejo - ela quer ser transformada em uma marionete de madeira. Katana está disposta, mas adverte-a - se ela passar por essa mudança, ficará completamente indefesa, incapaz de falar ou mover-se sem que suas cordas sejam puxadas, e pertencerá totalmente ao seu dono. É exatamente isso que Dahlia quer, e ela assina o contrato ansiosamente.

Katana começa a transformação, pintando costuras de boneca na pele de Dahlia. A tinta lentamente começa a fixar-se na mente de Dahlia, fazendo-a desacelerar e tornar-se rígida e leve. Ela está completamente incapaz de se mover sozinha ou falar quando Katana chega à pintura do rosto com blush e batom de boneca. Katana veste-a com roupas e cabelo mais apropriados para uma marionete, depois prende longas cordas aos seus membros. A boneca está quase completa! Katana procura um dono para a marionete enquanto os últimos vestígios da mente humana desaparecem. Katana testa a nova marionete fazendo-a dançar em suas cordas, mostrando que agora é um objeto perfeitamente indefeso.

Mais tarde, a transformação está totalmente concluída. Katana encontrou um comprador para a boneca e despede-se dela. O novo dono chega e examina a boneca, apalpando-a, enfiando dedos na sua boca e dobrando-a para inspecioná-la.

Dr. Katana está trabalhando em um novo soro de bimbificação quando Dahlia invade seu laboratório. Katana vê isso como uma oportunidade para testar seu novo produto e dá o soro a Dahlia através de um beijo. Dahlia resiste no início, mas Katana ativa o soro fazendo Dahlia ter um orgasmo. A heroína gradualmente perde sua inteligência e capacidade de falar. O cabelo e as unhas de Dahlia crescem mais longos, sua maquiagem fica mais marcante e seus peitos ficam enormes enquanto seu cérebro encolhe. Dahlia agora é a primeira bimbo bem-sucedida da Dra. Katana. 

Katana was all set for a quiet evening snuggled in her comfy clothes and socks when her boyfriend presented his latest strange invention: a magic spray that imbued objects with the power to move all by themselves! Ignoring his warnings, Katana carelessly sprayed the potion around the room, and scoffed as nothing happened. Of course, she failed to realize that when the mist sunk to the ground and settled, it would cover her boyfriend's rope kit! Now, with the ropes alive and determined to get some exercise, Katana found herself helplessly bound and gagged! She hopped about the apartment trying to free herself, only to realize she was helpless in their tight grasp! Struggling to her phone, she managed to use her cute little nose to dial her boyfriend, but thanks to the fat gag in her mouth, he couldn't understand her! Katana was left with no alternative to fight against the ropes, but the ropes had other ideas, and cinched her into a brutal hogtie that left her barely able to twitch! Poor Katana would be stuck until her boyfriend came home, but little did she realize he had his own surprises in store for her!
