(Before going into the chapter, I would like to point out that the following chapter is based on a short story I’ve read somewhere on the internet[I think on DeviantArt] but I wasn’t able to find the original or the Artist who had wrote it. For this reason, I rewrote it from what I remembered of it, as I had found it of great inspiration for an alternate ending. 
IF ANYONE KNOWS THE ARTIST OR REMEMBER THE NAME OF THE ORIGINAL SHORT STORY, PLEASE TO LET ME KNOW SO THAT I CAN EDIT THE POST WITH LINKS TO THE ARTIST TO LET HIM KNOW ABOUT IT AND TO GIVE HIM THE CREDIT HE DESERVE FOR IT. 
THANKS TO ALL FOR YOUR HELP)
And now, to the story:
Every story has a monster which is the personification of Evil, a malevolent creature bent on destruction of most characters surrounding it. Fine examples of such beasts are the monsters who lurks under the bed of kids and children. But it’s not always this the case.
George is a Monster with the hellish duty of lurking under children beds. He hadn’t been one for all of his life but, had steadily worked in Hell until he finally got promoted and assigned to lurk under their beds to scare them and instill terror and fear in their little hearts, which was then collected to resupply the dark energies powering the lowest level of Pandemonium, the Hell Capital.
 He’s not evil per se, he’s just doing his job.  
Nonetheless, when night came and he moved his scaly reptilian body out from under the bed, although it was pitch black in the room, he could see that something seemed amiss. He had gotten used to kids room, usually filled with toys and dollies, with stars and starships if the kid was a boy and with animals and castles if it belonged to a girl. But the room he was in that night was way different from any he had ever seen. 
Posters with menacing figures on the walls, explosions painted on the ceiling, a lone mirror placed strategically to give the owner a full view of the room directly from the bed.
And there seemed to be only one color in that room.
Black.
Strange.
Still, George was here to do a job.
He had to scare and, possibly, eat whoever was sleeping on the bed. And he counted to do so.
Walking on all fours he began stalking toward the bed, like a tiger would do when hunting its prey, his almost reptilian body shimmered a bit under the moon light coming from the window, his barbed tail swishing behind him. Moving closer and closer to the bed he could see the faint outline of the figure under the covers, and through such tiny detail he figured out that she was a young girl sleeping, although not yet mature enough to ignore monsters such as himself. 
Silently he moved closer, his claws extending from his front paws, as he readied himself to strike.
Right at that moment, though, the girl seemed to stir and, in the moment he took to freeze himself, he heard a surprised whisper and a quick movement coming from the bed. Growing worried, George moved closer and realized that his victim had managed to see him, somehow, and had applied the duvet tactic.
Growling in frustration he inched closer noticing that the duvet was extra thick and managed to create an impenetrable shield surrounding his would-be victim. George hated how kids were getting smarter and smarter these days. Somehow, thanks to some Intern Monster, probably, one kid had learned that Duvet covers were effective defenses against Monsters attacks. 
From then on, all kids used this tactic to protect themselves.
As he got beside the bed he stared at the formidable shield that the girl was using noticing that it was a massively heavy thing, extra-long, which managed to reach almost down to the floor, making it impossible for him even to return under the bed. 
But he suddenly noticed that there was a way for him to get at the girl.
As heavy as the duvet was, the girl breathing was still stable and that could only mean that she had a way to get oxygen from the outside. Walking around the bed he soon found that this girl had combined two defensive tactics into one, the first being the duvet bunkering, the second being the snorkeling technique.
Through the usage of a long snorkel, coming out of the impenetrable shield, she managed to get clean fresh air, even though she was covered entirely by the heavy duvet. With a smile on his lips, revealing his sharp razor like fangs, George moved closer to the tube, noticing how air came out of it and was sucked in and, at the same time, how the girl middle seemed to grow larger and smaller as she breathed.
This gave him an idea.
Opening his mouth wide and taking in as much air as he could, he suddenly closed his jaws on the tube creating with his lips a vacuum like seal around it, preventing any air to get out, with this done he breathed out into the tube with all of his might. 
At first there was a bit of resistance but, after a few moments, he managed to overcome it and suddenly noticed how the girl middle suddenly grew bigger under the cover. 
Knowing that in this way he could finally manage to get the girl to uncover herself from her shield indirectly he began pushing more and more air into the tube, watching with fascination how the girl figure began to swell, rising higher and higher, lifting the duvet bit by bit.
Feeling himself victorious, George, began to pump faster and faster into the tube, focusing only on pushing more and more air in the snorkel to finally get a chance at scaring the girl.
Meanwhile, the girl found herself unable to do anything. She had thought to be safe using the duvet and her dad’s snorkel but now something was pushing air into her through the same tube.
Slowly, the girl body began to grow, first her middle which started to get rounder, filling up with air, as it began to grow higher and higher, similar to a hill as it pulled the duvet from the floor as it rose up in the air. Then, slightly above that, two additional hills seemed to sprout suddenly, growing larger and wider, as a creaking sound started to fill the room as George kept pumping faster and faster.
The girl tried to move her arms, to free herself from the snorkeling tube but, under her heavy cover she realized she couldn’t manage to move freely and so could only hope that whatever was out there would stop sooner, rather than later.
George instead was feeling elated. He stole a quick glance toward the bed, where he could see that the figure on it was growing rounder and rounder, rising higher and higher, taking more and more of the heavy cover from the bed. Already he could see the tips of the toes emerging from under it and so, he re-doubled his efforts to pump even more air into his victim. 
The girl, meanwhile, was growing massively round. Her body growing into a massive sphere, engulfing both her arms and legs as it expanded wider and wider, her breasts, tightly kept in check by her currently too tight bra, growing bigger and bigger as they inflated with each pumped bout of air coming from the snorkel still stuck in her mouth.
She closed her eyes, feeling like she couldn’t hold anymore within herself, as she tried both to cry and scream at the same time, unable to do either of them.
George, instead, kept pumping more and more, using all of his lungs power to aid him in his task, feeling excited since he already could see the duvet leaving unguarded the legs of his victim, and yet her face was still under it, protected from that impenetrable shield. If he could manage to pump a little bit more into her, just enough to uncover her face, he would have won this battle.
As he kept pushing more and more air into the massively gravid sphere that the girl had become, a loud creaking sound filled the room, sounding like a ticking bomb waiting for its sudden release. 
Just as George was able to see the eyes of his victim getting freed from the heavy duvet, a loud ripping sound filled the room, quickly followed by a loud crackling sound as he suddenly was right in the middle of a massive explosion. 
As the room returned silent, George stood beside the bed, his lips still closed to the snorkeling tube, laying uselessly in front of him. 
He stared silently around the room trying to understand what had happened when a pair of red lacy bras flew down from the ceiling landing right on his head. 
Dejected, the monster returned under the bed, vanishing from view as what had happened in that room replayed over and over in his own mind.
