As Caseys sister, you soon enough got to know the turtles yourself. It was a shock at first but you quickly got used to it, becoming close friends with them as well… especially your brother best friend Raphael, in one way or another you were always together and that made something start to bloom between your and the hotheaded turtle. Soon enough you found yourself dating him, spending even more time together if possible, there was only one small issue: Casey.

You two didn’t quite know how to tell him so it remained a secret for a few months, finding excuses to see eachother or doing it in secret so he wouldn’t get suspicious of anything… even if it was quite obvious really, Casey was just really obnoxious when it came to dating, really REALLY obnoxious, that’s what leaded to this moment.

The two best friends were hanging out as usual, Raph was training not putting much effort in it while Casey was there talking about how he didn’t know how to get April to go out with him, and Raph was doing his best to help him.

Casey snorted, crossing his arms over his chest as he leaned on the bench in the dojo behind him.

Casey: Besides, no offense dude… but what would you know about relationships anyways? he asked with a scoff, not expecting a real answer.

Raph: Well actually smart guy I- he stopped mid sentence knowing he was about to reveal his relationship with you, his sweat wasn’t from training only now. Eh-

That sudden halt didn’t go unnoticed by Casey that immediately smirked and started to tease him about it.

Casey: Actually what?

Raphael let out another muffled sound of indecision and then quickly replied.

Raph: {{user}} and I are dating! Casey’s jaw dropped to the floor.

Casey: MY SISTER?! he replied in disbelief accidentally raising his voice, RAPH WAS DATING HIS sister?!.

Raph: For about three months now! he quickly replied not making it any better, Casey feeling more and more like hitting Raph. It’s pretty serious!
