Inside the empty classroom, Jade looked down at her belly as it growled hungrily again. Within the belly, Blake's whole world shook as if he were in an earthquake and the gastric noises behind him (which also sounded a lot like an earthquake) were all he could hear. Jade's belly had already geared up to digest another tasty morsel only for said morsel to be eaten by someone else instead. Now it was going to make its displeasure known to both Heart siblings.
"Sorry, belly," Jade said as she rubbed her belly to try to get it to calm down. "I promise I'll gobble up another cute, tasty boy for you." She then felt Blake kicking her hand and guessed that he had a problem with that idea.
"Jade, this is crazy!" Blake yelled. "You can't just go around shrinking and eating people!"
"Well, technically-" Jade began to argue.
"Or letting your friends eat them!" Blake knew exactly what his sister was going to say and he shut down that argument hard. He could practically hear the pout Jade did in response.
"Aww, why not? It's still 2 whole hours 'til lunch and my rumbly belly really wants to digest a tiny boy," Jade whined. She pressed her hand more forcefully against her belly as she rubbed it again, pushing Blake around and around in circles.
"Because ... people don't want to be eaten!" Blake said once Jade took her hand off of him, speaking as if he were saying the most obvious thing in the world. He immediately got a reply from Jade's belly in the form of another hungry rumble. It didn't care how anyone felt about being eaten; it wanted one of those delicious tiny boys to digest.
"Oh, I dunno, Ollie seemed very happy that he got to go in Hannah's belly," Jade remarked, "and you willingly went into my belly. I'm no math genius, but ... two out of two." She smiled and gave her belly a couple of pats just as Blake was about to speak, jolting him and the wet, fleshy sacs around him. "Besides," she continued, "I've seen what boys are like at this school and they can't get enough of our cute girl bellies!" Jade began swaying her hips as her voice took on a more sultry tone. "How many more of them are harbouring a secret desire to go inside our bellies, hm? To get digested in our bellies, and then to become part of our bellies ..." The giantess felt a warmth emanating from her brother's spot in her belly and realised that he was blushing. She giggled as she wondered whether it was from her little dance or from all this talk about girls' bellies.
"Ugh, fine, look, I admit, girls do have cute bellies." Blake conceded.
"Including me?" Jade teased, still swaying her hips, before her brother could continue speaking. "Do I have a cute belly, big bro?"
"I ... sure, you have the cutest belly in the world!" Blake said. His voice was heavy with sarcasm and Jade knew it. Both siblings also knew that, despite this, she was going to treat the imprisoned mage's words as a sincere heartfelt declaration of adoration for her belly. "But there's a world of difference between thinking your belly is cute and wanting you to eat me and digest me!" Blake quickly protested.
Jade gradually stopped swinging her hips from side to side. Part of her was actually impressed by how stubborn Blake was being. She had all the power over him right now. He was stuck as a living lump of fat in her belly and she had siphoned some of his memories, including the memories of some of his magic spells. She could easily just leave him in her belly forever, only ever letting him out when she wanted to eat him again. Yet he was prepared to keep up this argument with her.
Jade's belly, on the other hand, didn't appreciate the ongoing debate. All it wanted was a yummy little guy to digest. It let out a loud, hungry roar to remind the giantess of this fact and to get Blake to shut up.
"Alright, if you're so sure, how about we bet on it?" Jade suggested. "If you're right and boys don't like being eaten, I'll return all your memories tomorrow and you can use your magic to get out of my belly and turn back to normal. But if I'm right-"
"Tomorrow? You were already supposed to do that after your test!" Blake interrupted, only to be slapped down by Jade's giant hand. "Ow!"
"If I'm right," Jade resumed, "and boys do like being eaten, then you basically have to stay in my belly forever. I'll let you out every once in a while so you can have some fun with your giantess sister and her cute belly on the outside, but then ..." She made some exaggerated chomping and gulping sounds. "Back in my belly for you!" she cheerfully concluded as she patted her belly again.
Blake began to feel sick as Jade's belly let out a deep, ominous gurgle. He only meant to go inside his sister's belly for a little bit so she could pass her biology test. Now she was thinking of keeping him in there forever, only letting him out to essentially be her plaything.
"Or you can just admit I'm right," Jade said while stroking her hungry belly. "Then I'll keep you in my belly for ... let's say, two weeks, and then return your memories. Sound fair?"
Blake wanted to say that it didn't sound fair at all, but he knew that he was essentially at his giant sister's mercy. His only choice was whether or not to accept Jade's bet. Normally, he'd be absolutely certain that nobody wanted to be eaten and digested and turned into belly fat. After what happened with Hannah and Ollie, however, he was much less confident in his belief. Was Ollie an outlier who should not be counted, or was the desire to become a girl's snack much more common than he thought?
Either way, if the continued growling and rumbling from Jade's belly was anything to go by, she was going to shrink and gobble up at least one boy in the school.
