Giantess Unaware - The Cheerleader part 3

You snap back to reality as you wake up to an intense, recurring pressure.
"Why didn't he come?" You hear the cheerleader ask up above and realize that she is bouncing in place. You are flattered that she cares enough to keep waiting for you but you are flattened because she keeps waiting for you.

She shifts her body slightly forward, you feel her ass grind across your body and for a moment you forget your current situation and just enjoy how it feels. She continues bouncing her butt every so slightly and because of her position you feel only the softness of her wonderful ass cheeks.

You have enough of your upper body free from her booty to call out to her, you let out a weak "Help" that sounded more like an aroused moan than an attention grabbing yell. You try again "Help" but again it's just a pleasure filled moan. You can't help it, she's bouncing and fidgeting in her seat and it just feels so good. You feel the crevace of her butt cheeks tighen ever so slightly around your member, gripping it almost perfect and as she returns to her slight bouncing movements you are blown away by how good it feels. It's so warm and soft and you can't believe how her butt is actually stroking you and doing it well!

You feel yourself getting closer to climax when you remember that if you do 'finish' while in a tiny state you will actually shrink much smaller because of it... or at least that's what you heard on the news.

You begin to take deep breaths and try not to panic, you attempt to distract yourself and think of ANYTHING other than this intense pleasure. She continues bouncing and moving as you try to think of the most unsexy things imaginable.
"I just need to hold out until she leaves" you tell yourself but almost as if the fates were mocking you she puts in her ear buds and begins listening to music, almost immediately moving her hips to the beat. The pleasure intensifies as she grinds and bounces is a less subtle manner than before. Her ass cheeks are still perfectly squeezing and stroking your member and it feels better than you could ever imagine.

"I wish he would just come already" You heard her say up above. You knew she meant that she wanted you to arrive but the choice of words seduced you and temped you to 'just come already' and that was all it took. You released all your stress and tension as she continued to bounce and wiggle which caused you to unload even more.

For the briefest moment you felt no stress, no fear, no pain, only joy and relaxation, but that moment was shortlived as your body shrunk even smaller than before. You must have been the size of a cumb right now. You looked up at her butt as it continued to bounce infront of you and even compared to before was absolutely massive. The next thing you noticed was that you were no longer stuck under her, you were free! You took a running start in the other direction before realizing that your body was no longer crushed, you were good as new as a side effect of the 2nd shrinking but you were also in more danger than ever because your body would not be able to survive anywhere close to the amount of pressure it had before. You were safe again but more vulnerable than ever.

You try to run as best you can as the ground shakes under your feet to the movement of the cheerleaders butt. When you get to a reasonable distance you have a thought. "If I stay out here I will die for sure, my only hope is to get her attention" so with that you turn around the Cheerleader and her still bouncing butt cheeks and muster as much bravery as you can. It's all or nothing now...
