"God," sighed Karyn, as she lifted up her shirt, giving Jon a full view of her enormous breasts, snugly held by a bright blue bra, "I can't believe I'm letting you talk me into this."
"This'll be fine," said Jon, closely monitoring the eyedrop stopper from the vial of shrinking serum, "I'm just going to put a single drop on each breast."
"Just get it over with before some sees us."
Gently, Jon squeezed the two smallest drops of the green liquid onto Karyn's chest.
"Jon!" said Karyn suddenly, "It's working! I can feel it!"
The bra looked almost like a deflating ballon as Karyn's mounds shrank away, smaller and smaller, and the underwear hung like a scarf.
"What the fuck, Jon?!" shouted Karyn, looking down at her chest. Yes, her breasts were smaller. Far, far smaller than they ever were. Not only that, but they hadn't just decreased in cup size. Her nipples had shrunk as well. Now she was completely flat-chested, save for two grape-sized orbs with nipples no bigger than the head of a pin.
"Fix this," Karyn glared.
