Blake stammered uncertainly while his sister's friends stared expectantly at him. On the one hand, he didn't want Jade to get in trouble for not sticking to her diet, especially since he thought it was ridiculous that Claire was putting her on a diet in the first place. On the other hand, any exercise Jade did to get rid of some of the fat on her belly risked burning up Blake's biomass along with it. If that happened, his consciousness would be bound to her belly forever.
"Alright," Blake finally decided, "we can go to the gym. But Jade, if I tell you to stop, you stop, OK?"
"Um, OK?" Jade replied, not really understanding why Blake would tell her to stop. "Let's go to the gym then!" And with that, the four girls made their way to the gym. Jade's belly, still distended from all the food she ate, bounced the whole way there, Blake along with it. He just hoped that none of the girls would realise that he was starting to like it in a weird way.
When they got to the gym, the girls split up and did their separate workouts while music with a loud drum beat pumped from the speakers. Emily made a beeline for the punching bag and started going to town on it. Hannah decided she wanted to bench press some weights and Faith went with her to spot her. Jade found a mat and went to exercise on it. Since she needed to get her belly back to its original size, she thought that crunches would be a good idea.
"Owwwww!" Blake cried as Jade's abs squeezed down hard on him and his entire world folded in on itself. He could curse himself for agreeing to this. The tightness and the noises, he could maybe get used to, but this was by far the worst thing about being part of his sister's belly. When Jade lowered herself back onto the mat, Blake started wriggling to try to get her attention. As he did, however, something felt a bit off.
Before Blake could work out what was wrong, Jade lifted her shoulders and tightened her abs again, putting her brother in a world of pain once more before she lied back down on the mat. He tried squirming again and, once again, something wasn't right. It was as if he had shrunk some more, or like a part of him was missing.
Oh shit.
"Jade, stop! You're burning me up!" Blake screamed at the top of his voice, hoping that maybe his sister would hear him over the sound of the gym's music. If her next crunch was anything to go by, however, then no such luck. Once more, Blake had to endure the pain of being crushed by Jade's abs, and another small part of him disappeared. He still had enough left of his physical form to squirm, but his sister seemed to be ignoring all his struggles. He had to do something before Jade finished her exercise or there would be nothing left of him at all!
