Yes, breasts

Your belly bulging with milk feels something weighing on it and your shirt rides up.

“Whoops, guess those side effects are growing. I like big boobs, if you don’t mind them either!” Cokko tenderly gropes you.

“Ohhh, wow, look at that,” you manage to say between gulps. “I have big tits now!”

“I take it you don’t mind finishing up! That’s so great! They won’t last forever, so why not enjoy them while you can, right?” Cokko allows you to finish her milk.

When you stand upright, your belly bulges, but your easily HH cup breasts bulge farther. “I’m sooo stuffed...and my clothes don’t fit!”

“Stuffed from that end. Want to try the other?” Cokko winks at you.

“My butt can’t handle that,” you tell her, eyeing her big package.

“Give the chems time to work. Don’t your pants feel tight?”
