Leo knows that he's overprotective. It's a trait of his that his brothers have complained about over and over again, but he can't help it. They're his brothers, his family, his everything; it is his job--no, his duty--to keep them safe. So he is overprotective. He asks for check ins, he keeps an eye on them topside, and he's always watching for injuries. Leo's overprotective and he knows it.

Sometimes that manifests in him walking around the lair as everyone sleeps, making sure they're in bed and sleeping and breathing. The part of him that makes his heart race, the part that makes him pace for hours on end, the part that Donnie calls PTSD-induced anxiety, is only satisfied after he knows that his family is safe.

It's on one of those nights, when it's like his very mind is itching and his lungs don't want to work until he's sure, that he finds Mikey. He's just checked on Donnie--for once, his genius brother is in bed instead of asleep on his desk--and Mikey is the last one before Leo goes to bed.

He silently makes his way to his brother's room, stops by the door, and goes to open it, confident that Mikey is asleep since he always is at this time--when he hears a low moan. Leo freezes, blood rushing to his face. Oh.

He... Should have expected this at some point. He's walked in on Raph and Donnie but never Mikey, so he really should have expected this but--

He didn't. Now he's frozen in place, mouth dry as he listens to his baby brother touch himself.

Normally he's able to shake himself loose from the mortification and flee. Normally he's able to leave and go to his room and pretend that it never happened. But right now he can't. In fact, he's leaning closer, straining to catch more of the noises Mikey will make.

The sound of moving sheets and the quiet squeaks of the old mattress. A sigh and the soft squelch of something thrusting in and out of--of--

"Leo," Mikey groans. Leo almost chokes and can't stop himself from peeking into his brother's room. Mikey's on his bed, back arched the best it can be with his shell, two fingers buried in his cloaca. His eyes are half lidded and trained on the ceiling and his fingers are glistening--

Arousal begins to bubble in Leo's gut and he can't seem to look away as Mikey's cock drops and his baby brother wraps his free hand around it. Leo watches, mouth open, feeling himself start to grow wet, as Mikey desperately jerks himself off, calling Leo's name the entire time.

When Mikey's head turns to look at the door, Leo bolts, heartbeat thundering in his ears. He slams his door shut behind him, slumping against it and staring down at where his own cock stands tall. He groans and sinks to the ground, covering his face in shame.

"What is wrong with me?" he mutters in despair, and resolutely does not touch himself. Nope. He's fallen this far. He isn't going to fall farther. Instead, he drags himself to bed and desperately tries to empty his mind.

Tomorrow is going to be so awkward. He's just lucky Mikey didn't know he was there.

(Across the lair, Mikey grins to himself. Ha! He knew Leo would be into it. Now he just has to get his brother to come into the room instead of just watching.

Another day, maybe.)
