Leo
You were pacing anxiously in the room that you and Leo shared. How did you break this to him? He wasn't going to take it well, and why would he? You would be gone soon, for at least four years, and you would be around human guys be yourself.
"Y/n, what's wrong? You're wearing grooves into the floor." Leo asked, looking up from sharpening his katanas.
"Nothing." You sighed, standing still. A few seconds later, you were pacing again. You saw the flash of hurt on Leo's face, and immediately felt guilty.
"It's about school!" You blurted, sitting down on the bed.
"What's wrong? Are you ok? Do you have good grades? Are you pregnant?" You stared at Leo because of the last question.
"Have we slept together?" You asked pointedly.
"No-"
"Then no, I'm not pregnant." You snapped, as Leo came to sit by you.
"It's just...this is my junior year of high school, which means next year will be my senior year." You said.
"And?" Leo prompted you to continue.
"And so then I'll have to go to college for four years, and leave you and everything I know, and get a job, and be serious, and be around their guys, and it'll be really expensive." You said, letting it all out in one big sigh. You didn't tell him that your conselour had been hounding you to do service hours.
"College will be good for you y/n. If you want to go, that's your choice, and I won't stop you. I want you to be happy." Leo said softly, a smile on his face.
"Even though there will be guys?" You asked, raising your eyebrow.
"Y/n, is there any question about us? I am yours. You are mine." Leo said, his voice husky as he stared deep into your soul. You did the only logical thing. You leaned in and kissed him. Leo kissed you back quickly, running a hand through your hair, and laying you on your back. You eagerly wrapped yourself around him, pulling him close to your body.
"Hey Leo-AHHH!" There was a high-pitched scream from Raph, and Leo broke away from you with a growl.
"Later." He promised, before running after him. You pouted on the bed. Now you really wanted him.

Raph
You decided to tell him while he was watching TV, because he would be more likely to be fine with it. Luckily, he was in the two of yours room, watching wrestling.
"Hey Raph." You said, coming to sit on top of his shell.
"Hey." Raph said, grunting as you sat on him.
"What happens if I have to leave you for four years and move to another state?" You asked, watching as a guy got thrown onto the mat quite viciously.
"Oh, like for college?" Raph asked, after cheering.
"Yeah! You know about college?" You said, surprised.
"Donnie always wanted to go, but he's going to take it online." Raph answered, turning the TV off to pay attention to you.
"So I have to go for it in two years." You said.
"Y/n, if you want to go, then you can go. Don't let me keep you here. I want you to be happy, and if college is something that does that, then go for it. I'll always love you, if that's what you're afraid of." Raph said, flipping over so that you were laying on his plastron.
"I'm not scared!" You exclaimed, even when Raph gave you a look.
"I'm not." You said defensively.
"Sure thing y/n." Raph sighed. Feeling bad for turning it into an argument, you leaned down and kissed him gently. You felt him smile into the kiss, and he pulled you flush against him, kissing you deeper. His hands traveled from your waist, moving slowly upwards...
"Raph, I told you-ARE YOU SERIOUS?! LOCK THE DOOR YOU IDIOT!" Donnie yelled, breaking the two of you apart. Raph closed the door again, and turned back to you with a smirk.
"You had your chance. You'll just have to try again later." You said dismissively. Raph immediately scowled, and you felt guilty for lying. But not enough to change your mind. You still wanted him though.

Donnie
You were sure that Donnie would understand. He, after all, wanted to go too. You just didn't know how to break the news.
"Y/n? You look tense." Donnie said, when you found him at his desk in his room.
"A little." You admitted, sitting on his lap when he turned around.
"What's the matter? You're never like this." Donnie asked softly, rubbing your back. It reminded you of your mother.
"I...well, see it was college day in high school. My conselour really thinks I can get a good scholarship for a lot of schools. I'll have to leave at the end of next year for awhile." You explained.
"Oh y/n..." Donnie sighed.
"I'm not worried about you going to college. Sure, I'll miss you a lot. But I'll be doing online college while you're gone, so, in a way, it'll help with me missing you. I want you to be happy y/n, and I know that college will make you happy. So go. Have fun, make new friends. Just don't make new guy friends." He said, sternly at the last sentence.
"Thanks D." You grinned, leaning in to kiss him. He smirked, accepting the kiss, and kissing you harder. You swung a leg around the other side of him, effectively straddling him. Donnie slid a hand down your waist, dangerously close to your butt.
"Hey D, I was- YOU TOO?! WHAT IS IT WITH THIS FAMILY AND WALKING IN ON PEOPLE?!" Leo yelled furiously, slamming the door shut behind him again. You got off of Donnie, and flopped down onto the bed.
"You can't leave me hanging like that." Donnie protested.
"I am a strong, independent woman. I can do whatever the hell I want." You said, smirking at him.

Mikey
The most brutally honest question was the one floating through your brain right now. College. To stay or to go was the question of next year. Right now, you just needed to know if Mikey knew what college actually was.
"Hey Mikey? What do you know about college?" You asked, going to lay next to him on your and his bed.
"Oh I know a lot. Donnie's been talking about it for a gazillion years now. You get to go in about two years, when you finish high school." Mikey said eagerly.
"Um...yeah, you're right! Will you miss me when I leave?" You asked.
"Of course! Y/n, life is going to be hard without you here, I've already accepted that, but I know that college is going to make you happy. So you should go, so you can be happy. And then when you come back, it'll be even better to see you." Mikey said, a sad smile on his face.
"Yeah, but that's in a few years. Let's talk about something happy!" You suggested, grinning when Mikey lit up. You leaned over at the same time that Mikey did, and kissed. He kissed you hard, pulling you close to him. Surprised, but certainly not complaining, you kissed him back, wrapping your legs around him.
"Hey- YOU TOO MIKEY!"
"JEEZ WE NEED LOCKS!"
"YOU BETTER HOPE MASTER SPLINTER DOESN'T HEAR YOU!"
"STOP YELLING MY SONS!"
