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 is thoroughly gagged with a ball gag covered in microfoam tape. She's bound on her knees in duct tape. Dahlia sensually kisses, licks, and caresses the tape gag, admiring the way it shows off Katana's lips and muffles her moans.

Katana is a reporter who has been investigating Dr. Dahlia, a corrupt doctor who has been peforming unethical experiments on her patients. Katana enters the office disguised as a patient, but the doctor catches on and straps Katana to the exam table. She attaches probes to Katana's head, tits and pussy which send electrical signals to zap Katana's brain. Dahlia then inserts a speculum into Katana's needy pussy, and decides that her patient is ready to be turned into a fuck toy. Katana gets the rest of her thoughts fucked away by a fuck machine and is now Dr. Dahlia's perfect lab rat.

Katana and Dahlia just finished a long run and need to blow off some steam! Their feet are super sweaty after the workout and they decide to tease you with their stinky sneakers, socks, and feet. They tell you to play with your tiny cock and make fun of you as they take their shoes off and hold them to your face. Then they put their sweaty socks up to your nose, peel them off their feet, then rub them on your face and cock. They laugh at you and tell you to take it for them and to stroke more and more. They put their bare feet into your face and alternate between making you smell their feet, their socks, and their shoes as they count you down and command you to cum.

Dahlia goes to see puppet maker Katana and confesses her greatest wish- she wants to be made into a wooden puppet. Katana is willing, but cautions her- if she goes through this change, she will be completely helpless, unable to speak or move without her strings being pulled, and she will belong completely to her owner. This is exactly what Dahlia wants, and she signs the contract eagerly.

Katana begins the transformation, painting doll seams onto Dahlia's skin. The paint slowly begin to set in to Dahlia's mind, making her slow down and become stiff and light. She is completely unable to move on her own or speak by the time Katana gets to painting her face with doll-like blush and lipstick. Katana dresses her in more puppet appropriate clothes and hair, then attaches long strings to her limbs. The doll is nearly complete! Katana looks for an owner for the puppet as the last of its human mind fades away. Katana tests the new puppet by making it dance on its strings, showing that it is now a perfectly helpless object.

Later, the transformation is fully complete. Katana has found a buyer for the doll, and says goodbye to it. The new owner comes and looks the doll over, groping it, fingering its mouth, and bending it over to inspect it.

Dahlia is a patient at Dr. Katana's mental institution. She tells Katana that she thinks she's ready for discharge, but Katana convinces her to stay for one more session. Dahlia is told to stare at a spiral, and feels her thoughts slowly start to fade away. She is placed in a straitjacket and instructed to worship Dr. Katana's feet. Dr. Katana explains that she is going to turn Dahlia into a pleasure toy for the office, but needs to train her first. Dahlia worships a dildo with her mouth before stroking it with her feet. She then worships her new mistress, and signs some paperwork that officially makes her Katana's property.

Dr. Katana is working on a new bimbofication serum when Dahlia breaks into her lab. Katana sees this as an opportunity to try out her new product, and gives Dahlia the serum through a kiss. Dahlia resists at first, but Katana activates the serum by making Dahlia orgasm. The hero gradually loses her intelligence and ability to speak. Dahlia's hair and nails grow longer, her makeup becomes more bold, and her tits grow huge as her brain shrinks. Dahlia is now Dr. Katana's first successful bimbo.

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!
