There are a few people Mikey won't blackmail. Raph is not one of them. After carefully setting everything up, he set about quietly snapping photos. This was going to be the best. Blackmail. EVER. At least, the best blackmail anyone had against their older brother. When he was finished, he quietly exited the room and set about stealthily sneaking into Don's lab and carefully making sure the precious laptop wasn't boobytrapped. The last time, he hadn't checked, and Donnie had given him an earful and hidden it out of sight for MONTHS... Which prevented him from downloading some free comics. Pouting at the memory, he sat in the chair. Klunk meowed quietly and jumped up into his lap, sitting with his tail curled around his paws as he watched what Mikey was doing. "Check this out, Klunk," said Mikey, grinning. "You know that cat toy that Raph's had since, like, forever? Well, since the Christmas you joined us?" Klunk looked up at Mikey, who grinned and pointed at the screen. "Check this out, most faithful feline!"
MmMmM
Raph couldn't tell why, but he felt distinctly... odd... this morning. It was one of the days where he should be allowed to sleep in, so why was he awake? From the feelings his body was sending him, he was up WAAAAY earlier than he preferred. And why the hell were his arms covered in something scratchy? His blanket wasn't scratchy in the lea- He shot up, and found that he was in a ridiculous lace outfit that was decidedly feminine. He also had a wig on, and was holding a- His eyes widened. Oh crap. Oh crap oh crap ohcrapohcrap... The cat plushie he'd last let his brothers see him holding when he was THREE. This all screamed Mikey, and when there was Mikey, there was blackmail related motives. Which meant that Mikey wanted him to do something. And when Mikey wanted him to do something... He inhaled deeply, trying one of the methods Master Splinter had offered as a way to cope with his anger. Firstly, he had to get out of this outfit, and hide the cat better. Still taking deep breaths, he locked his door, and got to work. Damn this thing was constricting...
MmMmM
Mikey was clinging to the ceiling, waiting for Raph to come out and have his huge blow up. He was getting stiff, but it would be worth it... Finally, Raph came out of his room, looking completely normal. That is, until he saw the note stuck to his door, which he flipped over to see a picture of him. Mikey, even though he was on the ceiling, could SEE the vein throbbing on Raph's forehead. "MIKEY!" he roared, crumpling the picture in his hand and storming around the lair, looking for his youngest brother.
MmMmM
In the end, after Raph agreed not to completely pulverise Mikey (not now at least), Mikey told him what he wanted help with. Raph's eye twitched. "Blackmail wasn't needed to get me to agree with that!"
"Oh when you find out the next part I think you'll agree it was." Raph did agree. And then he pounded Mikey into the floor and acted angry. This lasted for five minutes before Raph paused to think, then grinned devilishly.
"As long as I get to make my own little add-on. THEN the blackmail wouldn't have been needed." Mikey grinned. When Raph got grins like that, the results were fantastic... as long as they weren't directed at him.
"Add on as much as you want, bro!"
I leave what the prank was to your active imaginations. ;)
