Felicia Fisher has returned to the lab for more work. She's feeling much better since her intake, and she's excited to do more.
She's given a toxic liquid to take, meant to relax her for more therapy.
As she takes it, she gets more and more loopy and silly till she needs to lie down. Once she's out, Madam Bliss claps and Felicia is at attention and fully under mind control.
Madam instructs her to do some things- dancing, shaking her ass, taking off her clothes.
Then, she puts on a strapon and sits back in a chair. She instructs Felicia to suck her strapon.
She complies and she's very good at it.
After a while, the effects of the toxin wears off and she comes to with a cock in her mouth. She jumps back and Madam claps to put her back under and declares the experiment over.
