Model Misbehavior (ft. Grell-Lover)

[Dungeon]

"Goodness, Undyne, your sense of fashion is appalling!" Another outfit was tossed lazily out of the closet as Mettaton continued his search for something to wear. He didn't have a show, but he was heading to the mall, and leaked it out to the paparazzi and some fans. He had to look spectacular! However, what with Alphys being bedridden with a cold, Mettaton was staying with Undyne. Unfortunately, he hadn't been able to properly pack, and was relying entirely on Undyne's clothes. Even worse, she had the fashion sense of a...well, a fish! "How am I to please my fans with such an awful wardrobe!?" In a fit of frustration, Mettaton tore a dress from a hanger, the sound of ripping fabric reaching his ears. The robot merely shrugged and tossed the ruined thing behind him. Undyne wouldn't lay a fin on him, and if she did, Alphys would tear her a new one. "I'm simply too precious to be harmed!" Mettaton mused to himself. After a good ten minutes of searching, he managed to locate a decent outfit: Black leather pants with "Bonus Round" on the back in pink glitter (he had no clue why Undyne of all people had those), a white V-neck that ended just above his midsection, and a pink leather jacket, completed with a black, glittery scarf.

(Perfect~!)

Undyne was not a fish to be messed with. She had warned Mettaton about packing enough clothes as it would be a hassle to keep bothering Alphys by coming back because they forgot something, so she made sure the bot got everything before he left. The warrior facepalmed, wondering how Alphys could deal with such a BRAT-then it struck her. She remembered how Alphys said to punish the star if he got out of hand, even though Mettaton had not been told prior to the trip. The last straw was when Mettaton ripped one of her dresses and simply shrugged it off. That was one of her favorite dresses, dammit! AND the brat had the gall to go through her best clothes in the first place!

After he had already dressed, Undyne made her decision to show the brat who's boss. Without warning she grabbed Mettaton by his ear, dragging him over to her bed before sitting down and throwing him across her lap. "I've had just about enough of you, brat! It's time I showed you who's in charge here!"

[Dungeon]

Mettaton was taken by surprise when Undyne suddenly grabbed him. He could've sworn she was out training or something! But what was even more surprising was when she tossed him over her lap. "Wait, Undyne! You wouldn't do this to a star, would you?" Mettaton, foolishly believing he could charm his way out of the all-too-familiar position, looked back at Undyne with a smirk, wiggling his ass a bit.

[Blazecraft]

Undyne raised a brow, as if that was the most stupid question she had ever heard. Which to be fair, it probably was. "Yes, I would. Especially when said star has been a pain in my ass!" With that she pulled down the pants he was wearing and started immediately smacking her hand down on his ass.

[Dungeon]

Mettaton yelped at the tug, or more so of having Undyne see his rather risque form of underwear. He immediately started to struggle at the smacks, twisting his hips to try and avoid her calloused hand. "Ow! Undyne, you should be-Ouch!-thanking me! That dress was hideous!"

[Blazecraft]

A thong. Really, how attention-seeking could he get?! Well, he was about to see the effect of angering the warrior dressed in such a way. Smirking a bit, she grabbed the waistband of the underwear and yanked upwards, effectively wedgie-ing the bot as she continued to spank him. "You had no business going through my stuff, brat! And it's none of your business what I like to wear! That was one of my favorite dresses, and you WILL be paying for it with your ass!"

[Dungeon]

The wedgie caught Mettaton off guard completely. Hell, he might've been into it if his ass wasn't being assaulted by Undyne. The robot gave a cute little noise of embarrassment, and clenched his arms to his chest as the spanking continued. "S-Stop it, Undyne! I understand that you're jealous of my superior sense of style, but this is no way to work through your jealousy!"

[Blazecraft]

Undyne's visible eye twitched as Mettaton had the audacity to be a smart-ass in this situation, but got an idea of how to break the bot's attitude right in two. Using the same magic she used to summon spears, she summoned a glowing blue paddle, and after tugging up on the wedgie again and holding it in place she started to rapidly smack Mettaton's ass all over, quickly turning it a dark pink.

[Dungeon]

Mettaton's yelp turned into a shriek at the sudden use of the implement. While the pained just her hand was at least tolerable, the paddle, burning with energy, quickly quelled any other words from the robot, replacing them with yelps and cries. Mettaton arched his back at the wedgie, but this only made his ass a much more luscious target.

[Blazecraft]

Undyne hadn't stopped in the slightest, and didn't stop until his ass was a bright red like her hair. "You learning anything, brat?" She asked as she paused his spanking, ready to continue if needed.
