Donnie churred as he felt a slick tongue lick its way up his length. The olive skinned turtle bit his lip as he gripped the arms of his chair. Panting, Donnie looked down at the one who was making him feel like this. Amber eyes stared at him from under the work table. "R-Raph." whimpered the bo staff wielding scientist as his brother/lover took the head of his cock into his (Raph) hand.
"What is it Donnie-boy?"
Don bit his lip. "I...I-"
*Lick* "Tell me Don. I wanna know~" Raph purred up at the scientist.
The purple wearing turtle whimpered as he felt Raph's hand ghost up and down his length. But before Donatello could tell his lover what he wanted, he heard the door to his lab creak open. Raph quickly hid in the shadows of the desk and Don covered his "little problem" under his lab coat.
"Hey Don?" asked a voice. Donnie looked over his shoulder to see his eldest brother standing in the door way.
"Hey Leo. What is up?"
"Have you seen Raph?" asked their "fearless" leader.
Donnie blinked. "No. Last I heard he was going to go on a run with Casey. Why?"
Leo sighed, "No reason. Well, I am going to go meditate." Donnie nodded and the minute the door closed, he pushed his chair away from the desk. He panted as he stared at the smirking face of Raph.
Without a single word between them, Don moved himself so that way his behind was in the air and that the chair was pressed against the door. With quick movements, Don had locked the door. Raph's smirk transformed into a grin as he made his way over to the wanton turtle.
Don practically came right there when he felt his mate's length rub against his entrance. Raph leaned over his lover's shell, pressing his face against Donnie's ear hole. "Do you want me to enter Don?"
The purple masked turtle whimpered, which caused Raph to chuckle. With a churr/moan hybrid, Don felt Raph enter him. The scientist moaned as he felt Raph thrust into him with out caring that Don might be in pain. But that was the thing: Donnie LOVED pain. That was why he was always sad that he didn't get to fight as much as his brothers but right now, he loved the pain that his sadistic brother was giving him.
"R-Raph. H-Harder..." he groaned out, digging his fingers into the chair beneath his face. All he got was a grunt and Donnie cried out as Raph's dick brushed against his prostate. Donatello felt tears of joy stream down his face as his brother continued to fuck his brains out.
Soon, Donnie felt an all to familiar pressure build in his loins. "R-Raph, I...I..."
Raph said as slow as he could, "Come for me Don."
Donnie cried out, "RAPH!" and came all over the floor and his plastron.
Raph continued to thrust into his brother until he came with a roar. He pulled himself off of Don and sat down on the floor next to the curled up turtle. Don just looked at him with a smile...
