A swirling pink-and-blue concoction

"Oh crap." Blake suddenly doubles over, clutching at his abdomen and hissing through his teeth, legs shaking. "Just cramps," he manages to bite out, holding a hand up as Sandy and I lurch forward instinctively to help him. After a few moments, he reaches out behind him, grabbing onto one of the shelf posts, and slowly hauls himself upright; his face is flush, and he's sweating profusely. A few slow, deep breaths later, he pulls his shirt off over his head, mopping at his brow with it... but before he can move, his face screws up with what I assume to be the shock of another wave of cramps.

"We should get out of here," I finally declare, stepping forward to help Blake walk, looping his arm over my shoulder, and mine under his other arm and around his chest. "This could be some kind of poison, and there's no telling who might've heard that wand go off. Sandy, could you get him some water?"

"Right!" She fishes around in Blake's bag for a moment before producing another water bottle, and he drinks greedily from it as we hobble out of the aisle. It doesn't look like he's going to collapse... but while Sandy's leading the way, checking down each aisle as we proceed to make sure there aren't any more surprises, I can't help but notice that something seems to be... off.

Firstly, he feels lighter, and I could swear that he got a little shorter out of the corner of my eye. Did his jaw change, too? It looks smoother, both skin and bone. That, and it kind of feels like his chest is getting softer, almost as if it were growing to fill out my hand. Before I can ponder that further, Blake stops, sighing with relief. "I think... I think I'm good, now."

"You sure?" I let him go anyway, and he takes a few steps on his own, pacing in a circle, before arching his back in a huge stretch. "Man, that was rough. Good thing it's over."

No, Blake, I think we have a bit of a problem. His voice is definitely a touch higher now, and he's definitely slimmed out; he's probably lost about two inches, tucked in just above the waist, giving him some slight curves, and he seems to have grown a pair of A-cup breasts to match Sandy's; they're tiny, but well-rounded. Hell, he could probably pass for her little sister now.

"Sandy, you might want to come take a look at this." I say slowly, struggling to keep my tone neutral. She turns and heads back over with a "What's up?", while Blake looks at me quizzically.

...Then he follows my gaze down to his chest.

"...What the fuck?" He breathes, hands immediately shooting down to his new breasts, squeezing them experimentally. Quickly, he undoes his jeans, stretching out the band of his boxers so he can check their contents... and seems to be rendered speechless by what he finds-- or, rather, what she doesn't find. "I-- wh-- but--"

"Blake is a unisex name, isn't it?" I muse- Sandy just bursts out laughing.
