As the movie went on, Josh continued to struggle in vain under his step sister's powerful rear, hoping at some point she would switch position and allow him to escape from this torture and trying to punch her to force the issue, but with the awkward angle of his body his blows were more like submission taps and at his reduced strength Megan didn't even feel there was something down there.
Megan finally offered Josh a chance to escape when she inclined her body in order to get a sip of her drink, lifting her butt a bit and giving Josh an opportunity he took with some unusual display of athleticism. Out of desperation and ignoring the pain on his body he stood up and managed to move fast enough, jumping away just in time before Megan's butt came back with full force to support itself in the seat cushion. Looking at how big Megan was from this perspective he could only start to believe God existed, he didn't know how on earth did he survive for so long.
Taking a couple of minutes to recover his breath and stretch his tired legs, Josh thought about what the next step should be. Megan could still reposition herself in the seat and trap him against the seat backrest if she decided to bring down her legs and sit correctly, so the first thing to do was to move from there towards the actual safest position, closer to the seat's armrest. Once there, he looked up and saw his evil step sister fully engrossed in the movie, which made Josh feel a weird wave of humiliation. At this size he was so powerless against Megan she could easily have him desperate to save his live, and she wouldn't even have to notice it!
However, he considered his options. Megan was evil, but she wasn't the reason he shrunk, at least he didn't think so. After all he shrunk at his job before Megan was around, and from her previous pranks he knew Megan wouldn't leave anything by chance, for example another person taking up this seat to torture him. And even if Megan was.. Megan, she was still his step sister, so hopefully she would help him or at least take him to a safer environment at home. Staying at the Premiere definitely wasn't an option, who knows what could happen in a place constantly filled by strangers? He could get stepped on or sat on by any random person, get sucked up by the vacuum cleaner when another employee came to clean.. The risk was just too great.
Above him, he heard Megan giving a cute laugh at one of the movie's scenes, reminding him there probably wasn't a lot of time left. With Megan still stretching her legs on the seat in front of her, Josh decided to move between her legs and from there find the point where he could start climbing her body. At best he would be able to be noticed, at worst he could be hitching a ride home where he could probably get help from someone more reliable.
Between her legs Josh looked up at the imponent body of his step sister and the popcorn bucket covering part of her chest, turning around he saw part of the giant screen, mostly covered by the front seat and the silhouette of Megan's giant shoes. As he approached Megan's thighs Josh felt a mix of emotions, awkwardness from getting so near her small sister and feel the warm of her body heat in contrast with the warmth he still felt after being crushed by her butt, fear of being discovered by Megan who could do whatever she wished to him at this size, and hope that everything would go as planned.. At least until some light object hit him on the head and made him fall on the cushion again
Josh groaned as he felt the weird object hitting him, it felt like a big but empty box so the hit wasn't hard but he still wasn't expecting it. Turning around he saw the culprit, a small popcorn kernel around half his size was in front of him. At this point Josh remembered how weird he was that he actually shrunk, and his curious mind couldn't help but take over as he got close to the kernel and wondered about the possibilities.
He got close to the kernel and started to think about if it was possible to replicate the shrinking process, picturing making people small or making things big which would solve so many issues around the world.. energy consumption, space, hunger, the possibilities were endless! He tried to lift the kernel and found that despite being so light he didn't have a great leverage to do so at this size, and taking a small bite from it noticed it was harder to do so, but still edible.. He started to wonder how long would it take him to finish this off by himself, so captivated that he didn't notice a small "Oh!" sound coming from above, or a big moving shadow coming towards him.
Fully unprepared, it was way too late to escape. Megan's hand took a hold of the popcorn kernel he was studying, along with Josh, closing her fist in such a way Josh didn't find a way to try and struggle. He couldn't even see thanks to Megan's giant fingers, and could only scream Megan's name, overcome with fear, as he felt the weightlessness on his body, Megan was lifting her hand, towards her mouth to eat the little popcorn that fell out of her bucket
What happens next?
