Handing Sarah another Vial, she smirked as she swallowed it in one gulp before handing it back. Her smile faded though as the change set it. Mary couldn’t see her very well to begin with, but she soon vanished entirely beneath her bust line. The sound of her panties hitting the floor make Mary smirk.
“Y-you said you weren’t going to make me any younger,” Sarah whimpered.
“I didn’t. I shrunk you a foot. Now you won’t have to bend over to suck my dick. It’s at mouth height,” Mary explained.
“I guess, but now it’ll be harder to suck you off. I can’t get as much of you in my mouth,” she argued.
Mary kneeled down. Her huge mass loomed over Sarah. Though she didn’t really want to admit it, being even smaller did kind of turn her on. Now Mary was even bigger. Her dick was almost the full length of her torso. Just the thought of her being impaled by such a massive rod made her shiver.
“Are you going to shrink me more?” She asked trembling.
“No. I have something else in mind,” Mary chuckled and handed her another vial.
Sarah swallowed like a good girl and watched in amazement as her boobs grew. “Oh my,” she gasped as she went from a C to a D. She was handed another vial and felt her ass expand. “You’re making me so sexy,” she purred.
“I’m turning you into my perfect fuck toy,” Mary clarified as she gave her another vial. Sarah noted that she should be concerned, that she shouldn’t drink these vials blindly. But she couldn’t help the fact that being forcible changed was turning her on so much. She drank the next vial and felt her boobs grow to an E cup, which on her 4 foot frame make them look insanely big.
“My boobs again?”
“I wanted to experiment. If you drink the vials sequentially, the effect is doubled each time. I wanted to see if the same was true if you broke up the doses. And it would seem it does, otherwise you’d be an F cup right now,” Mary explained as she gave Sarah another vial. Once again her ass swelled.
“Trying to keep me even?” Sarah purred, her entire face flushed in arousal.
“I told you, I’m making you my perfect fuck doll,” she repeated and gave her another vial. This one made Sarah cum on the spot as her pussy quivered and grew in size.
“M-my pussy,” she moaned.
“Have to make sure you can fit my cock.”
The thought was incredibly arousing, but a small voice did inform Sarah that it would probably be impossible to take Mary’s full length without injury. “Uh, Mary,” Sarah meekly attempted.
“Quiet,” Mary silenced as she forced another vial into her mouth. Sarah drank it obediently but didn’t feel any change.
“What was that one?”
“Don’t worry about it.” Mary forced several more into her mouth, one after the other. Sarah felt her stomach gurgle but the feeling subsided after a minute. She wanted to ask what they were, but knew better at this point. “That will do for now,” Mary decided and stood up, her dick hitting Sarah in the chin on the way up.
“Now what?” Sarah asked.
Mary smiled.
