Matt had always been a little oblivious at times. So when he joined Mello in the Mafia he didn't notice the fact that being favored by the boss had put him on the bad side of a few of the criminals.
He was walking down the hallway back to his room, head buried in his gameboy, when a much larger man walked past, shouldering him roughly into the wall. Matt's goggles cracked as he made contact with the rough stone. Being Matt, he dismissed all other injury and made sure his gameboy was alright before checking the damage to his goggles. Then he keeps on walking.
Later that night Matt is slumped on the couch, playing through a game he has no doubt played through several times before.
"Hey, Mells?" The blonde Mafia boss grunts in acknowledgement. "Think you could get me some new goggles? These ones are cracked."
"How the fuck did that happen?" Matt shrugs
"One of the guys bumped into me." Mello pulls himself off the bed where he was sprawled.
"They just bumped into you and then you're goggles are cracked?" Matt shrugs again.
"I crashed into the wall." Mello growls, stalking across the room, although his hands are gentle when he removes the broken goggles. He lightly touches the bruising where the rims had dug into his skin.
"Are you hurt anywhere else?"
"Nope."
"Matt, if I have to I will inspect every inch of your body." Matt blushes cherry red.
"Uhh...Umm… My shoulder may have hit the wall?" he sputters. Mello tugs down the collar of Matt's striped shirt to reveal a dark purple bruise blooming across his shoulder. Mello's hands clench into fists.
"Who did this?"
"I'm sure it was an accident, they-"
"Who did this?" he demanded.
"I don't know. I was playing my game." Mello curses under his breath.
"I'm going to go kill the fucker who did this." He stands, heading for the door. Matt calls after him.
"Mells? Why are you doing this?" Mello freezes, hand on the door. Turning slowly, he walks calmly and carefully back across the room, not hesitating for a second before pressing his lips against Matts. The kiss is returned eagerly, Matt pushing himself closer. Mello breaks away, kissing gently across his jaw and down his throat. But when he reaches Matt's pulse point he bites down roughly, bruising the skin. One more kiss to Matt's lips and he pulls away again.
"Because you're mine and nobody gets to touch what's mine."
And then he walks out the door, leaving a very shocked Matt behind him.
Matt had always been a little oblivious at times. So after that day, he didn't notice when Mafia members twice his size flattened themselves against the walls and whimpered when he passed by.
