Mikey was nowhere to be seen. He made sure of that. Cloaked by shadows that were lurking in the Lair's corners, he made sure his breath was silent too. His heart still beated, but he made sure to slow that down as well.

The lab door was cracked open, but the lights were off and there was no movement inside suggesting that Donnie was elsewhere.

Mikey studied the lab through narrowed eyes, waiting for his intuition to kick in. Of course it wasn't unusual for Donnie to leave the door open when he was too agitated to close it properly... Forgetting about the door and remembering to turn off the lights sure was..

Undecided, Mikey stood rooted until he heard soft footsteps coming at him from the kitchen. In a narrow corridor no shadow would hide him from his ninja brothers.

Recognizing that it's a no-choice situation, he dashed through the door in one silent flick of dark.

Donnie's laptop was in sleep mode, some mad atomic screensaver being the only scource of light in this gloomy room. Flickers of soft bluish, reddish and otherish light coming from the sleeping computer danced on various glossy equipment that his genius (boring) brother used for his science mumbo-jumbo. Normally, Mikey would appreciate peculiar dance of light on peculiar shiny bottles and glass tubes, but this time he kept focus and went straight to Donnie's desk. Сouple of days ago he saw Donnie hide it here.

His hand barely reached the top drawer, when the door behind him closed.

"That was a little reckless of you", - Donatello said, flicking on the light. Mikey cursed inwardly, his mind racing trying to figure a way out of this. Donny locked the door.

Mikey turned to look at his brother, keeping his eyes as wide and innocent as he could.

"Adorable", - Donnie commented, steping toward him, somehow resembling a hunting cat circling a mouse - "but it won't work".

"I.." - Mikey cleared his throat. Coming into Don's territory was reckless, but there was something he needed to do before he got caught. Maybe he could play doctor's side of his smart brother. ".. I just need something against pain"

Donnie blinked, his eyes quickly searched the sea-green body, the predator look in them gone.

"Are you hurt?"

" I may be if they catch me"

Donnie came to stand right in front of him, looking down into smaller turtle's blue eyes.

"What exactly are you looking for, Mikey?" he asked and hovered over his brother, reaching for the drawer that Mikey didn't have time to look into.

Mikey felt heat crawling up his neck as his brother nearly pressed onto him.

"This?" The olive-colored hand brought up a tube of lube before Mikey's eyes.

Mikey hastily nodded. Four times.

"You should have thought about it yesterday" - Donny said mildly. He popped the cap "Turn around"

Mikey hesitated.

"Turn. Around." - Don didn't raise his voice but the hint of steel that suddenly filled it was enough to make the younger obey.

Mikey turned his shell to his brother and braced his hands onto the table when a slight push made him lean forward.

Donny wasn't the worst option, he kept telling himself when warm hands squeezed his buttocks and started moving on his skin, tracing along the outlines of his defined muscles. He trembled, when Don's precise fingers took his tail and massaged it lightly. Mikey felt his guts to warm and heart beat faster. He drew a deep breath.

"Hold your tail up" - Don's voice husked beside his ear, bringing Don's hot breath to his skin. Mikey did as he was told, and forced himself to relax when he felt cool wet substance being smeared across his tail hole. A cold feeling there was contrasting the warm tingling that now spread all over his body.

More lube was added and a finger slid into him. Mikey tensed out of reflex and his ass immediately got slapped. He whimpered and forced himself to relax. Thick sleek finger was moving in and out, stretching him, pulling at his muscle ring.

When Donnie added the second finger, Mikey hissed and earned another slap. Don pushed his shell forward and he obediently lowered his plastron onto the desc.

Don hovered over him and Mikey turned to look at his face over his shoulder. When their gazes met, the orange-banded turtle whispered: "Whatcha gonna do?" His genius brother grinned. "You know the answer" - he said.

"You could let me go" - Mikey suggested

"I could..." - Donny scissored his fingers inside his body and watched Mikey's breath falter. He slowly pulled his fingers out and smeared some lube on his throbbing cock.

"...but I won't" - he finished and slowly pushed into his brother.

Mikey bit his lower lip.

Donnie was moving in and out of him in tantalizingly slow motion, making the smaller mutant feel filled to the brim and then leaving an empty gaping hole.

Mikey squeezed his eyes shut, feeling that each time Donnie's cock slid in along his prostate the bulge in his lower plastron grew a little more, the inertia of Donnie's movements causing him to rub against the desk, stimulating his groin further. Donnie's slick hand touched the sea-green tail and Mikey moaned, unable to contain his erection.

Donnie moved back from the desk, pulling Mikey with him, and the later sighed with relief when his cock slid off the desk. He reached to pump himself - he was needing it badly, but a strong hand caught his wrist. He groaned "really?"

An ominous chuckle was all he got for an answer.

Suddenly Donnie pulled out and urged him to turn around. Grapping his brother's legs, the smart turtle held him in place while thrusting into his warmth with increasing speed. Donnie's thrusts became harder until the taller turtle slammed in and froze for with eyes closed. Mikey felt warmth pouring into him. His cock was painfully hard now and he risked sneaking a hand down his plastron to milk it.

"No." Don pushed his hand aside and reached for the lube once again. Still inside, he lubed Mikey's cock and started pumping it. Finally gratified, the orange banded turtle closed his eyes and rolled his head up, succumbing to the feeling. It didn't take him long to cum into his brother's palm.

First thing Mikey did when Don finaly pulled his member out of him was look at the clock. It was quarter to ten.

"Say, can I stay here for today?".

Don shook his head: "Don't cheat, man. You wanted lubed, I got you lubed. Now off you go."
