While Tasha sleeps, Marie's body undergoes the final changes turning her into a bimbo, which was part of the plan all along. Marie had willingly been infected, and was sent to infiltrate Tasha's safe house and get more of the bimbos inside so they could overtake the inhabitants of the safe house and turn them all into bimbos.
Marie and two bimbos quietly enter Tasha's room where she was still sleeping, Marie unbuttons Tasha's pants and pulls them down while her companions remove her shirt. Marie smiles as she moves in between Tasha's legs, running her tongue along the sleeping girl's pussy while her companions start on her breasts, getting an involuntary moan from Tasha. It was her job to get Tasha herself infected, and when that was done, they could go out and infect more people.
Tasha lets out a louder moan and wakes up, pinned down by the three bimbos, she can't move while they rape her. "What's... ohhhh... going on?" She asks, the bimbo virus was already starting to work on her brain, starting to transform her in mind and body. She moans louder while Marie spreads the folds of her pussy, sliding into Tasha deeper followed by a finger, Tasha moans louder, and Marie hears more moans from the other rooms in the safe house, it was beginning.
Tasha lets out a scream as she orgasms, her breasts are now inflated to EE-cups, her former desires and hopes replaced by the sexual drive of a bimbo.
"Must, have sex!" the new bimbofied Tasha says, pushing against Marie's head like she wants her to go deeper still. "Ohhh, fuck me!"
As they settled down and the last of the inhabitants of the safe house where converted, it was time to get out and about town.
