Figuring that there was no way he could get Jade to stop exercising in time, Blake racked his brain for a spell that could at least preserve what physical body he had left. As his sister did another crunch, however, he realised that he was running out of time, so he just screamed the very next incantation that popped into his head. One more crunch later and his entire world went black. Did he pick a bad spell for the situation? Did he mess up casting it somehow?
Then, as suddenly as it disappeared, the world around Blake came back into view, only this time, there was a barbell with some weights on it moving towards him and away from him. He heard a deep gurgling sound coming from behind him - or was it beneath him? He also felt a soft, squishy substance push on him from all around. When he pushed against his surroundings, it still felt as if he was missing part of his body.
"Ah," Blake uttered as he realised what had happened. The spell he cast must have teleported him out of Jade's belly fat and into someone else's. Sadly, it hadn't restored any of his lost biomass. At least he wasn't in immediate danger of losing his entire body now, but he needed to know whose belly he had ended up in.
Suddenly, everything around Blake shifted and tumbled, leaving him disoriented for a few seconds. What he didn't realise was that this was his new captor sitting up after putting the barbell back on the squat rack and finishing her exercise. He then saw Faith come into view, which ruled out the possibility of being in her belly. Then he remembered that he saw her follow Hannah to the weights earlier, and it all fell into place.
Now that Blake knew that he was in Hannah's belly, the next thing he needed to do was let her know. Trying to speak to her was no use because the music in the gym was too loud. Instead, he struck out forcefully against the belly fat around him and kicked outward as much as he could.
Hannah let out a confused grunt when she felt something funny near her belly button. She quickly rubbed her belly in the spot where that strange sensation occurred, blocking Blake's vision for a moment. When it returned, he saw Faith staring straight at him with an expression he couldn't read.
"That was weird," Hannah remarked. "It felt like something was just kicking inside my belly." Her eyes then immediately widened when it dawned on her why she had that feeling. "Blake?" she exclaimed, looking down at her chubby belly.
"It appears Jade's brother has chosen you to be his new host," Faith stated evenly, trying to hide her jealousy at not having Blake in her belly. "Although his stature has diminished since our first sighting of him," she added as she kneeled down to get a closer look at Hannah's belly. "To which demon lord did you sacrifice your body, Blake?" she asked the tiny mage with a cheeky grin. In response, Blake started squirming again and tried to tell her what actually happened, but even being this close to Hannah's belly, Faith couldn't hear a word he was saying.
"Maybe we should go to the bathroom," Hannah suggested. "It'll be quieter in there so we can hear what this one has to say." She gave her belly a couple of pats that jostled the fat around Blake, and then the two girls got up and started walking to the bathroom. Blake immediately noticed that the fat in Hannah's belly shifted and wobbled a lot more compared to his sister's belly, though he wasn't sure if his biomass being reduced contributed to that feeling.
Hannah and Faith soon entered the ladies' room and, luckily, found it empty. Faith took a seat on one of the toilets and Hannah stood in front of her, resulting in Blake's view being dominated by his fellow mage's face. The larger girl also noticed that her belly felt oddly warm in Blake's spot. She gave it a brief stroke with her fingers and the warmth seemed to intensify. She giggled as she guessed that this was probably her captive blushing.
"So ... welcome to my belly, Blake," Hannah said happily as she peered down at her belly again. "I hope you don't mind, it's a bit more jiggly than your sister's." To drive her point home, she gave her belly a little shake that made it and Blake jiggle, and then chuckled when she felt her prisoner's blush get even stronger. She still didn't know why Blake was now in her belly instead of Jade's, but she loved every second of it.
"Hannah, wait!" Blake shouted as he tried to bring himself back to his senses. "There's something I need to tell you!"
"Speak, imprisoned one," Faith commanded. As a mage, she already had a good idea of what was going on, but she needed Blake to confirm it.
"So the thing is," Blake explained, "while I'm a bit of fat on your belly, I can get burned away like any other bit of fat. The more of me that gets burned up, the weaker I become. If I lose all my biomass, I'll be trapped in your belly forever, unable to move even a little. So when Jade started doing crunches, I started getting burned away. I tried telling her to stop, but she didn't listen, so I had to try something else. I cast a spell I thought might help, and it teleported me into your belly, Hannah."
As Blake concluded his recount of what happened and waited for Hannah and Faith's responses, Hannah's belly gurgled particularly noisily for a few seconds. This caused Blake to get hot and flustered again, and he silently bemoaned how much this kept happening. Yes, he liked Hannah's belly a lot, but he was concerned that she might mistakenly think he wanted to stay in there forever. Or, now that she knew that burning him off would seal his fate, she might decide to finish what Jade started regardless.
"I will inform Jade and Emily about this development," Faith said resolutely as she rose from the toilet. Hannah stepped aside to allow her to exit the bathroom. Then, once Faith was gone, Hannah thought about what to do with Blake. She had wanted to get him in her belly at some point and, now that he was, she had to admit that it felt nice having him in there. Would that change if all his biomass went away, or if he regained it somehow? Or maybe she could take this opportunity to have a little fun with him in private.
