You've swallowed the chocolate but the taste isn't leaving your mouth. In fact, it seems to be spreading, the rich and sweet taste of the chocolate soon all that you can taste. "W-What's...what's that candy doing?" you ask, fear in your voice as you catch sight of your tongue. It's a brown thing, the color of the milk chocolate you had eaten before. In a mirror over the counter you can see that your mouth looks, well, different. The warmth that you felt isn't going away, and it's only spreading as your lips take on that same brown color, teeth changing to match.
"I-I'm changing into chocolate?!" You manage to gasp out, grasping the situation quickly. Your face is already changing, the scent of chocolate soon all you can smell, which along with the taste is almost overwhelmingly delicious. You manage to stop yourself from biting your tongue with your now chocolate teeth as the change spreads over your face like a brown wave.
"Mmmhmmm." The baker laughs a bit, seeming pleased. "100% high quality milk chocolate. What happens to you after, well, we'll see." He moves up and takes a piece of your nose, breaking it off in one hand. Your shocked gasp is tempered by the fact that you're finding that speaking is near impossible and by the dull sense of pleasure the breaking filled you with. That dull sense explodes a thousandtime as he puts it into his mouth and eats it, the warm feeling of your...your nose being consumed sickening you in how good it feels and how right being consumed is.
An itching follows, your nose beginning to regrow itself, chocolate pushing out of the hole as your face, perfectly rendered in cocoa, is whole again. You can move it, change expressions, do everything you could when meat, the same with your changing body, but sound refuses to emanate from your brown lips. You look down, your clothing beginning to smudge from the sensation of chocolate on fabric and, with a resigned internal sigh, you take it off. Looking down, you see the chocolate has covered your torso and arms, spreading to your legs.
The warmth seems to fade and begins to die as it spreads down your legs, the change nearing its completion within a few minutes. Like your upper parts, your lower ones are perfectly rendered in cocoa, including an unfortunately erect member. Unlike the rest of you, this seems permanently sculpted this way and based on the way your fingers run over it, it's even more sensitive than before.
You shake your head after a moment of examination, face filled with a nervous look, molded eyes showing exactly the amount of fear you have. You can't give voice to your concerns and your terror but it's clear from your expression. The baker, seeming to sense it, smiles as if to reassure you. "Don't worry, you'll love what comes next~" as he leads you to the back room to...
