They've got music blasting as they lock the door behind them, humming through Raph's creaky old speakers and rattling up through Leo's bones. He presses his mouth to his brother's hard enough to bruise, legs twisting together and heat pulsing between their hips as they sway to the song. 
It was a bad idea 
Calling you up 
Was such a bad idea 
'Cause now I'm even more lost 
Raph's hands drag down his shell, across his waist, fondling his ass like the prized possession it is. Leo wriggles into his touch, tail fluttering eagerly to wrap around his brother's fingers and squeezing tight. 
It was a bad idea 
To think you were the one 
Was such a bad idea 
'Cause now everything's wrong 
Leo lets his younger brother scoop him up and carry him over to the bed, lets Raph toss him onto the blankets with a squeal. The sheets reek of them, of all the sweet and beautiful things they've done together in a place where no one can touch them. 
You put your hands under my shirt 
Undid my bra and said these words 
"Darling, you're so pretty, it hurts" 
You pushed me up against my wall 
Threw my clothes down on the floor 
"Darling, are you ready for more?" 
Raph yanks off his gear with a growl and Leo strips Raph almost as easily, at least before his hands are seized and pinned over his head. Raph lunges into another kiss, swallowing with fire and want and aching, spinning need. 
It was a bad idea 
Calling you up 
Was such a bad idea 
I'm totally fucked 
It was a bad idea 
To think I could stop 
Was such a bad idea 
I can't get enough 
Once, pressure on Leo's wrists would have made him squirm, uncomfortable with memory. But he's been clean for a while now, and Raph has been there every step of the way, keeping him together, keeping him sane, without pity or disgust, rubbing the dark tingles away. He likes it when Raph helps, he likes this, and that's okay. 
It was a bad idea 
Needing you so late 
Was such a bad idea 
'Cause I can't think straight 
Their cocks are out, glistening and pushing together, their mouths pressed hard enough that they truly feel like one turtle. But it's not enough, Leo wants more, he  needs  more. An impulse strikes him and he suddenly slips away, darting between his brother's legs. 
It was a bad idea 
To bring you back home 
Was such a bad idea 
I need to be alone 
"Wha--" Raph flips, but it's too late, and Leo's mouth is already on his cock, nostrils flaring. A turtle's can take a more a lot quicker than a human's can and it's easy to swallow Raph whole, that great beautiful cock of plunging down Leo's throat like it was always meant to be here. 
You put your hands under my shirt 
Undid my bra and said these words 
"Darling, you're so pretty, it hurts" 
You pushed me up against my wall 
Threw my clothes down on the floor 
"Darling, are you ready for more?" 
"Fuck," Raph moans, throwing his head back. His hands tighten around Leo's shoulders, squeezing the back of his neck with just enough force to bruise. Leo's lips quirk into a smile around his prize as he sucks and lips even harder, pressing his jaw open to take still more of Raph's girth. 
It was a bad idea 
Calling you up 
Was such a bad idea 
I'm totally fucked 
It was a bad idea 
To think I could stop 
Was such a bad idea 
I can't get enough 
Raph will punish him later for the insubordination, but that's okay, Leo loves being punished as much as Raph loves doing the punishing, because Raph's punishments are hot and loving and never destroy him the way Leo's old methods did. 
Bad idea 
Bad idea 
Bad idea 
Bad idea 
Maybe fucking his brother  would  be a bad idea in the real world, but this isn't the real world, this is  their  world, the world where they're beyond all pain or fear. The only thing that matters is Raph thrusting down his throat like he's fucking a flashlight, hard enough that Leo's own cock rubs sweetly-painfully against the floor. 
You put your hands under my shirt 
Undid my bra and said these words 
"Darling, you're so pretty, it hurts" 
You pushed me up against my wall 
Threw my clothes down on the floor 
You said "Darling, are you ready for more?" 
"Fucking love you, angel," Raph groans, his words splintering into a half-crazy churr. "Love you so much." Leo can't exactly say it back, but he  can  suck his brother's dick like a hurricane and blissfully hump his leg. So, he does just that, the two of them still rocking against each other in time with the beat. 
It was a bad idea 
Calling you up 
Was such a bad idea 
I'm totally fucked 
Nothing can touch them here. There are monsters in the world, cruel hearts and cruel words and shadows beyond counting, and there's no making that way go away. But there will always be the two of them, Leo and Raph, brothers and lovers, facing it together. And nothing can make them go away, either. 
It was a bad idea 
Calling you up 
Was such a bad idea 
I'm totally fucked 
It was a bad idea 
To think I could stop 
Was such a bad idea 
I can't get enough 
The song surrounds them before it peters, wrapping them in a warm blanket, because that's what this is all about, isn't it, the song and the room and the girl in red. It's love, crazy stupid wild love that lights up like a match and frightens all the ugly people away.
