The baby-blue potion in the curvy bottle

You pick up the second one: a bottle with wavy sides, making it nice to hold, filled with light-blue liquid.

"Oh, this one's an experiment I'm doing with some spare ingredients," the Witch says. "The Coven lent me some of their... organic catalysts, and I thought I'd see how they worked with my brew. Let me know if this one sits well, at least."

You pop the cork and take a sip, finding the contents nice and creamy. Swallowing down the pale-blue potion, it reminds you of yogurt, tasting none too different. Smacking your lips, you give the Witch a ponderous look. She lifts a finger to her chin to watch you closely. When you start to think about how it's sitting, you get the sense that it didn't go all the way down.

"Hmm... You should at least be satiated by the drink. Tell me, how's your appetite?" she asks. You meow uncertainly, and she moves in to poke your tummy with the long black nail at the end of her slender finger, making you flinch.

The sudden movement seems to stir the potion inside you, and you're certain it went right to your chest. A hiccup escapes, causing the Witch to peer at you curiously. You meow again, this time even less sure of yourself, and get cut off by another hiccup.

"Well there's one side-effect..." the Witch drawls, gaze poring over your body. You feel another hiccup swelling in your chest, and squirm under her gaze. "Odd... Are you lactose intolerant?"

You begin to shake your head when the next hiccup hits, and you notice your costume feels tighter. Looking down, you see your breasts actually filling it out more than they used to, bouncing in the wake of your hiccuping. They were admittedly modest a few moments ago, and definitely not this... bouncy.

"This is an unexpected development," says the Witch, her eyes lingering on your breasts longer than your own. "Perhaps the catalyst was too potent..." She leans in, watching as your chest grows with scientific intensity.

You gulp, trying to suppress the next hiccup, but it only delays the inevitable, and with the new weight in your bosom you're sent teetering forth into the other woman by the spasm. You fall against her, mewl muffled by her own soft melons as she catches you against her chest.

"Woah there, kitten! A little top-heavy, aren't you?" The Witch lays her hands on your arms, and you pull back blushing.

As you steady yourself you find your collision applied an unfortunate pressure to your swelling sweater-puppies, and you're more than a little surprised by the milk leaking onto your costume.

"Oh my. There seems to be another side-effect to this one." The Witch reaches out again to poke your breast this time, eliciting another mewl as more milk squirts down your chest. While they seem to have stopped growing now, the lactation doesn't seem to be slowing. "It's likely temporary, sadly enough... Although if you're disinclined to your new cup size, I might be able to help get it out of your system." She eyes you salaciously.

You give an uncomfortable meow, curtailed again by a hiccup that sends your bosom to bouncing. Swallowing the creamy aftertaste of the potion, you wonder whether you should just be on your way...
