"Open your eyes," Raph whispers, and gives another vicious snap of his hips. Leo whimpers, legs shaking as he struggles to stay upright. He presses against Raph's chest, eyes squeezed tight. 
A hand comes down to slap his cock and Leo squeals like a stuck pig. "I said, open your fucking eyes," Raph snarls, spittle warm on Leo's ear slit. 
Leo's eyes fly open almost of their own accord, and he flinches at the sudden burst of light. The mirror house is supposed to be empty at this hour, but Raph somehow figured out how to get the generator running when they broke in, and now everything is silver-white light, panes spinning off into the distance until Leo feels nauseous. 
Through his blurry vision it looks like the room is full of turtles, shining green bodies splashed across the floor and ceiling and endlessly reflected across walls. They move as one, twisting, writhing, melting into together until they seem like one being--except one is fucking and the other is very clearly being fucked. 
Raph is smiling that fucking smirk of his in every reflection, and in every reflection, Leo is shuddering in his arms like a toy, face flushed, eyes huge, sweating and moaning like a professional porn star. Leo can see his own tail twisting between his legs, wagging for more like a fucking starter's 
"A room fulla beauties, and I picked the prettiest one," Raph says, punctuated with another vicious thrust, and Leo should roll his eyes, but he barely has the strength to breathe right now. He can't get away from the state he's in right now, how utterly debauched he looks. 
His cock bobs weakly up and down, weeping with need, and his legs are spread humiliatingly wide, as if showing off the bruises already sprouting across his thighs. Raph's wearing all his gear, but he's stripped Leo of everything, and he feels more exposed than he thought possible. 
There are trick mirrors, too--Leo can see ones where they swirl into each other like water, where Leo is swollen up like a balloon on Raph's monstrously distorted cock, where Leo splits into pieces, as jagged and scattered as he feels. He wants to shrink away from it all, but that only pushes him farther back onto Raph's cock, farther back into that horrible, wonderful pleasure. 
"Beautiful, ain't it?" Raph grits out, his voice splitting off into a groan. "My sweet little slut, showin' off for me." He smacks Leo on the thigh. "C'mon, angel, shake your ass for daddy." 
It's degrading, humiliating, and Leo should kick the shit out of Raph for daring to use such words. But instead, he watches as the reflected turtles suck in a breath and slowly, deliberately circle their hips. He feels himself shifting around on Raph's cock and it should feel so awkward, but the turtle in the mirror moves like something awful. 
"Fucking hell, babe," Raph groans, his hand dragging down between Leo's legs. "You--you're made for this, you really are." His other hand gives a vicious shove, and Leo yelps as he slams forward, barely managing to catch himself by propping his hands against the glass. 
The mirror turtle stares back at him, eyes wide, because now Raph can shove even deeper, hard and vicious enough that Leo can feel his own cock bumping against the glass. And that shouldn't turn him on, shouldn't make him grind desperately towards the cool, unforgiving surface, but he can't help himself. 
"Come on," Raph purrs, wrapping his fingers around Leo's cock and dragging him along the mirror. "Give us all a show." 
And Leo just does that, a squeak-scream ripping out of him as white paints the glass a dozen times, reflected in every shining eye. Raph laughs, wild and brilliant, before digging sharp fingers into Leo's hips to fuck him harder.
