A/N: Omg, this is literally the fluffiest thing I've ever written. XD

Warnings: cuteness, AU after First Class, Erik/Charles, daddy!Erik, daddy!Charles. Post XFC. One of those the-beach-scene-ended-happily things.

Disclaimer: Do you really think a little fluff-writing fangirl owns X-Men? If you do, I'm flattered!

Forget your troubles, come on, get happy

You better chase all your cares away.

Shout hallelujah, come on, get happy.

Charles never realized just how loud children could be until he started living with a brood of them. And really, they were quite loud. Their minds went a mile a minute, their mouths even faster – they were constantly laughing and frolicking and shouting, and while Charles loved each and every one of his students dearly, it could get to be just a little too much sometimes. Which explained why he was sitting in his study, staring listlessly out the window at a clear blue sky, his reading glasses pushed down on his nose, as he listened to the sounds of fun outside.

Finally, he forced himself to look back down at his papers. This is your fault, he told himself. You're the one who chose today to actually get some work done.

Five minutes had barely passed before he stood and went to the window, looking out. Everyone was outside, enjoying the lovely day – it was the first truly pleasant day of the year, and soon these days would pass to be replaced by agonizing heat. Even Erik was outdoors, acting as a monitor to ensure that none of the children accidentally killed themselves (or each other).

Charles slipped into his lover's mind with ease, smiling to himself. Erik would never, ever admit it, but he was actually enjoying himself. The students weren't being bothersome in the slightest, and Sean, Hank, and Alex were putting on quite a show (well – sort of. Sean and Alex were chasing Hank with water balloons – and even Erik couldn't suppress a laugh when Hank finally turned around and pounced on them.)

Still watching through Erik's mind, Charles projected, Please don't let Hank kill them. It will traumatize the students.

Erik's mental tone was amused. I doubt that. I think they'll find it quite funny.

Charles rolled his eyes to himself and replied, Yes, well, I suppose they were asking for it. Will you go and check on David? He's upset about something.

Charles watched from the window as Erik went over to a small, dark-haired child crouched on the grass, and smiled paternally to himself. Erik hadn't been too pleased to learn that Charles had a child with an ex-girlfriend, but Charles hadn't exactly known either, so Erik hadn't been able to stay annoyed for long (and it didn't hurt that David was essentially a smaller version of Charles, complete with big blue eyes and an adorable/annoying inability to control his telepathy.)

He slipped back into Erik's head, watching his conversation with David.

"What's the matter, David?"

The little boy sadly held up his toy airplane, which was currently missing a wing. "It broke."

Erik twitched his fingers, and the metal wing snapped back on to the airplane. David's face positively lit up, and Charles definitely wasn't imagining the affection that went through Erik.

I know you're in my head, Charles, Erik reminded.

Sorry, Charles said. It's just so adorable, I can't help myself.

Oh, quit being such a girl.

You're the one making my son's airplane fly around by itself.

But I'm doing it in a manly, disciplined manner. You're acting like a housewife.

Whatever you say, Erik, Charles responded, smiling.

Will you come outside now? Erik asked as he made David's plane soar around the child's head. Your son would probably much rather play mind-games with you.

No, I think he'd much rather force you to fly that plane around all day, Charles teased. Besides, I still have work to do.

Erik looked over his shoulder to face the house, and Charles gave him a wave from the window.

Please, Erik thought, knowing quite well that Charles couldn't resist for much longer.

Alright, fine, Charles gave in. But just to be cheeky, he raised his hand to his mouth, pressed his lips to his palm, and blew an elaborate kiss to Erik.

You're a strange creature, Charles, Erik thought back grouchily, but he glanced around and caught the kiss anyway. Then, with the utmost care, he pressed the kiss to his heart.

Oh, and I'm the girl here?

Just shut up and come downstairs.

Yes, Mrs. Xavier.

If you call me that one more time . . . Erik threatened.

You'll what? Hold out on me? Charles teased.

. . . Don't be ridiculous.

Charles's only response was a projected wave of smugness and happiness as he went outside to join his lover and his students.

A/N: I like this whole fluff thing. :D Reviews make my day!
