Mike went into work feeling slightly optimistic. He wasn't sure why he did, by all accounts things were going horribly and anyone with decent or even poor pattern recognition skills could assume that it was likely to go poor again tonight, but he wasn't as afraid as he had been before. Maybe it was just because the Toy animatronics all seemed to want to please him as much as they pleased themselves with him, or maybe, as he refused to let himself think, he was actually starting to not only get used to being used, but actually starting to enjoy it.
No, he told himself, that was ridiculous; he was just enjoying the various sexual skills that the toy animatronics came equip with, that was all there was to it. He entered the office, sat down, wound the music box, hit play on the recorded message, and set to his nightly tasks to avoid getting caught by the animatronics as he listened to the message that had been left for him by the man on the phone.
"Hello? Uh, hello? Hey, I just wanted to remind you of a few things. Look out for a wired, almost static like sound, it's what lets you know that Mangle is coming in. Be sure to check the vents, they're the animatronics' main entry to you. Uh, be sure to use your flashlight to check anything that might appear at the end of the hall, and as always, be sure to keep the music box wound. Oh, and one more thing, watch out for Balloon Girl. Some people forget to keep track of her, they tend not to see her as an actual animatronic. Because she looks more human-like as is so still for so long, most people see her on the camera and assume she's just a prop or a plastic statue, but she is an actual animatronic just like the rest. She's not my least favorite, the Puppet will always have that award, but she's certainly the most annoying. She messes with the flashlight so you can flash away the others. What's more, she seems to put out some sort of frequency that disables the other animatronics' docile mode so they can and will get as rough as they want without asking. So yeah, watch out for that. Anyway, good luck."
This was news to Mike. He had indeed been operating under the assumption that the little statue of a girl holding a balloon had in fact just been a statue, but no, that would be much to easy and the universe just wouldn't stand for his life being easy now would it. Evidently not. Mike wasn't too worried at first though, as all he had to do was avoid her getting into the room in the first place, which wouldn't be too much harder than the others he thought, so long as he kept a close eye on where everyone was.
The issue was, when he went to find her, she wasn't in her usual place. What's worse, she didn't appear to be anywhere at all. He checked all the rooms carefully, as well as the hall in front of him and both of the vents. He couldn't find anyone. This made him paranoid at first, but he calmed when he realized that them not being anywhere near him meant that he might be safe from them for the entire night.
Unfortunately for him, the rooms were not empty and he was not alone for the night, he was just not checking the right place. He didn't notice the little Balloon Girl animatronic under his desk, hiding where she had been since he had first arrived at work that night. She waited patiently, knowing that if she was too slow when she started, Mike would be able to escape her. If she acted too soon, he would be ready for her. So she waited, and watched.
After a few hours, when Mike was fully relaxed and complacent, Balloon Girl sprung into action, undoing Mike's pants and freeing his cock before he could figure out what was happening. By the time he looked down to see her, she already had his cock in her mouth and was sucking on it diligently, bobbing her head along his stiffening length as she hands fondled his balls and her tongue swirled around his length.
Balloon Girl listened to him moan for a few moments, then paused to say, "I hope I'm not bothering you sir, feel free to continue your work." She went directly back to deep-throating Mike, who saw no reason to stop her with how calm she was being. Even if she did turn dominant later, with her size, she couldn't hurt him. And besides, he could still keep the others from getting in.
At least, that's what he though. Unsurprisingly, having your cock sucked expertly tends to divide one's focus, and he ended up spending most of the time just enjoying the feeling of her throat around his cock. When he finally did remember to check the hallway, he realized that he couldn't. His flashlight was busted. She giggled around his cock, causing him to groan, pushing her head down to the base and cumming down her throat.
Balloon Girl took it all, swallowing it happily. She then stood, undressing. As Mike had thought, her member was barely three inches in length. "May I please myself now?" She asked. Knowing he didn't really have the choice now, he nodded, and finished removing his clothes for her. She smiled, but there was something... unsettling about it. She lined up to his ass, but before she thrust in, her member began to grow, increasing and length and girth like, well, an inflating balloon.
When she was done, her cock was over a foot in length. Balloon Girl picked Mike up, surprisingly strong, "We're going to fuck you now sir~" "We?" He questioned, whimpering when he felt Toy Chica behind him, lining herself up to his hole with Balloon Girl. They both pulled him down as they thrust up with such force that they both got a few inches deep inside his ass together. Mike screamed out, but when he did, he gagged as Mangle descended, burying her entire cock inside his throat with a moan. Mike could no longer see, but he knew that Toy Bonnie and Toy Freddi were inside as well, because they grabbed his wrists and brought his hands to their cocks.
Realizing he had been fooled and accepting it, Mike gripped their cocks and began jerking them off hard as Mangle fucked his throat viciously, moaning louder whenever his groans of pain from behind double stuffed vibrated her cock. They kept going, Balloon Girl having disabled the safeguard and letting them be as rough as they want. They had him for the next hour, and planned to leave him exhausted and completely covered in their cum.
