Jade was blissfully enjoying the sweet taste of forbidden cupcake when she suddenly heard a noise. It sounded like her brother's voice, but it was saying he was on her cupcake and begging her not to eat him. With a puzzled look on her face, she peeked down at the cupcake, and her eyes widened when she saw her tiny brother stuck in the frosting!
"Blake? Why are you so small and why are you on my cupcake?" Jade asked, astonished by what she was seeing but trying to keep her voice low so her mom didn't overhear her. For a moment, Blake considered making up a story that let him keep his magic a secret, but then he realised that, if he was ever going to get back to normal, he would have to tell his sister the truth. He took a deep breath before launching into his story.
"There's this girl I like at college, and I really want her to like me. Only thing is, I'm not a tough guy or very strong, so I ... well, I used magic to summon some spirits to help me. I've been studying magic for a while so I thought everything would be fine. Anyway, the spirits promised to make me so tough I can't come to any physical harm, but at the cost of my size. As you can see, I took that deal. I ... I thought she'd be impressed by how tough I am. Only thing is, they were supposed to teleport me to her, but instead I'm here with you."
For a few seconds, Jade had a blank expression on her face as she tried to process everything her tiny brother had told her. Normally, she'd dismiss a story like his as outlandish, but there was no other explanation she could think of for why Blake was so tiny. She took a couple of breaths before replying to her brother.
"First of all, how come you never told me you could do magic? Now there's finally something cool about you!" Blake smiled inwardly, thinking that it wouldn't be his sister if she didn't find a way to tease him. "Second of all, that still doesn't explain why you're on my cupcake."
"Well I had to get you to spot me somehow," Blake explained, "and I thought you'd see me when you brought the cupcake up to your face." Suddenly, a familiar thunderous rumbling reached his ears. When it stopped, Jade's mouth opened wide and rushed towards him. He screamed in terror as he feared he was about to be eaten. Luckily, the bite of cupcake his sister took didn't have him on it, so instead he was treated to another round of watching Jade chew her food - a sight he couldn't help but blush at.
"Oh, I probably scared you there, didn't I," Jade apologised sheepishly. "Sorry, bro. It's just that mom's got me on this stupid diet and I'm just so hungry all the time!" She lowered Blake and what was left of her cupcake down to her slightly pudgy belly, where he could hear it gurgling as it digested the bits of cupcake she had eaten so far. "She says she's worried about me getting fat, but she's just overreacting. I mean, sure, my belly jiggles a bit." Jade put a hand on her belly and jiggled it up and down, causing Blake's blush to deepen. "But that's no reason to make me practically starve myself, right Blake?" Another rumble came from her belly, this one so loud that Blake could actually see his sister's belly vibrating. As it came to a stop, she pressed her hand into her belly and moved her hand in circles, making the fat on her belly swirl around. "You hear that? My poor belly just wants to be filled up."
Jade then lifted her half-eaten cupcake along with Blake back up to her face and she couldn't help but giggle when she saw how red her brother's face had turned. "Does my brother like my belly?" she teased. "My jiggly, rumbly belly?" Blake was already too flustered to respond and his sister's insinuation that he was somehow attracted to her belly didn't help. Especially since it was true to a certain extent. "Oh wait, didn't you say those spirits made you indestructible or something?" That snapped Blake out of his stupor just as Jade's belly rumbled hungrily again.
"No, Jade," Blake pleaded, "I know what you're thinking, don't do it." Unfortunately, the way Jade was looking hungrily at him and licking her lips told him that she had already made up her mind.
"Be a good brother and fill up my belly," Jade said sweetly before shoving what was left of her cupcake into her mouth with Blake on it. Now he got to witness his sister's teeth crushing and breaking apart her food while her saliva coated it. At one point he heard a puzzled "Hm?" coming from the back of Jade's throat, and then he was pressed between her tongue and the roof of her mouth. Then he heard a satisfied "Mmm!" before she resumed chewing.
After what felt like an eternity, Blake was washed away towards Jade's throat along with all the cupcake mush in her mouth. With one loud gulp, he and the cupcake disappeared down the throat and quickly made the journey into Jade's stomach. Blake landed on a pile of more of that same mush he had seen in her mouth, and his ears were assaulted by the sounds of the stomach groaning and rumbling as it digested the food Jade had eaten and demanded that she eat more. These were soon joined by a rhythmic thumping sound from one side of the stomach, which Blake quickly deduced was his giant sister patting her belly. He started making his way over to where that thumping sound came from.
"Mmm, you were even tastier than the cupcake!" Jade remarked. "Yummy, yummy, big bro in my tummy!" She then felt a fluttering feeling somewhere near her belly button. She figured it was her delicious brother banging on the wall of her stomach, and she rubbed and patted her belly in the spot where she felt him doing that. "Now use your magic to fill up my belly and stop it from rumbling!"
As Blake pounded on the stomach wall, he suddenly felt it push back against him, and then it knocked him off his feet when the thumping noise resumed. It was clear that Jade wasn't letting him out of her belly any time soon. Was there anything he could do while he was in there?
