You feel woozy for a moment, bracing yourself on the countertop next to the chocolates.
The feeling overcoming you is hard to describe. The closest thing you can come up with is the sensation of water from a hose flowing over your skin... but no, it's like it's underneath the skin. Settling in places. It feels... heavy somehow.
Then something catches your eye. As you look down at the counter, you see your stomach starting to arch outward. You gasp and go pale. Your body is inflating! Pumping outward. You panic, lifting your shirt, seeing the small belly you're beginning to form. You hadn't been crazy fit before, and had just the slightest line on your midriff where your abs were, but it was gone. You'd always been thin up until now. The flat expanse of skin you were used to seeing was puffing outward.
You feel a tightness in the seat of your pants. Skinny jeans weren't so great for people putting on a bit of weight, obviously. You wince as the waistband tightens, button trying it's best to hold the fabric together. You wince as the denim digs in on your hips. You struggle with the button, eventually freeing it from the loop of your fly, giving you a bit more comfort.
You stand straight and see yourself in the reflection on the glass casing of a bread shelf. Filled out noticeably. A rounded stomach that strained your shirt, wider overall appearance. Even your face and chest had filled out. You weren't fat per se. You were pretty chubby though. The swelling had slowed down. It looked like it was stopping.
Your hands grip your swollen belly, feeling the soft flab that had grown there. Your eyes shift over to the chocolates, trying to understand what had happened to you. Looking up, you see the baker placing a few chocolates into a big box as he hands it to you. Instinctively you take it.
"Wh..what'd you do to me?" You ask, voice trembling. The baker smiles again "Not a thing, bud. You're the one who took a sample... plus, I just make things like this possible. Someone else sent you here to find out what it's like to be a bit heftier, I guess."
He walks around and pats your gut. "I didn't push you the whole way. I'm not cruel or anything. But..." he trails off and looks at the platter of chocolates. "Those chocolates are pretty addictive, aren't they? I bet you even want one now." He motions to them. You find you've been staring at them. You lick your lips without realizing you did it at first.
"You might want to find out who wanted you to come here and wanted all this to happen to you. Maybe you can convince them to get rid of whatever curse you're under. Or, you know, you could just sit down and have a few more chocolates. I gave you a nice big box, after all... just, remember. They're terrible for your figure." He said with a laugh, shaking the box in your hand a bit. You hear the chocolates hitting the plastic walls of their individual plots in the box. With that, he turns you around and pushes you out the door. When you turn around to protest, you're greeted to a steel gate in front of the shop, which is totally empty and dark beyond the barricade.
You feel a dull panic as you walk off, feeling the slight bounce of your new belly as you go.
