By the time you revive enough to take stock of your surroundings, you are fully inside the nurse, and you realize you must have gone all the way up her vagina and are now in her uterus, which is a warm and comfy place as you would have expected. Rather nice actually.

It would be even nicer if you were alone in here...

With a shock, you realize some of the flesh surrounding you is not part of Cassandra, but is another individual [that bulge you noted in the nurse's belly? That wasn't a tenth of the size of your new roommate. Have you been shrunk too? Well, that can wait...] A male individual. One who was quite pleased to have a female form pressed against him. One who was going to take full advantage of that female unless you do something...

"Hey! Stop! Don't... Cassandra! Help!"

"I don't think my little boy needs any help." is the depressing reply.

"Your little boy is 6' of rapist."

"Ah, they grow up so fast... But that makes you a fine toy for him to play with."

"But I didn't sign up to be his plaything!"

"That's what you are now tho, so be a good little toy."

There is no time for further protests, which Cassandra seems unlikely to concern herself with. This lout was not just sitting there as you tried to get the nurse to help. Despite your frantic efforts, he was positioning his staff, and now you gasp as he rams it home, and begins the age old rhythm.
It takes him just a moment to climax, which surprisingly is not a relief for you. Somehow, he was at least supposed to see to your please even as he was violating you. However, he does not withdraw and only rests for a moment before resuming his plumbing, an act you do not approve of either, and have as little control over.
Having gotten his first eagerness over with, he takes his time this time, which at least allows you time to get to a more comfortable posture, as much as that is possible with him tangled up with you in a cramped space. But the final result is much the same as you feel his fluids splash into your deepest parts.
However, he starts a third time, and you start to feel your own excitement building. You debate whether to aid that for your own pleasure, or to hinder just to show he does not control you, but it doesn't matter as you are hit by a wave of joy.
Your lover does not stop, or even slow down. His thrusts build you back up to an even bigger explosive organism that you scream into his ear. [You hope it deafens him, but he likely regards it as a surrender on your part.] And he is not done yet. His efforts build up to a frantic pitch and you feel both his and your excitements growing and growing, until the two of you reach a sweet simultaneous miracle that just burns you out.
