Snap. Snap. Snap. 
Their hips are moving in time with her soft sighs, with the crack of a bone between her elegant fingers. Tang Shen sucks down the marrow, chin glistening, eyes sharp in the dim light. She smiles at him and Yoshi smiles back, wincing at how sore and filthy his teeth are.
But she just smiles. Smiles, smiles, and her teeth are filthy too. Filthy with dull, cracking red and sharp like so many knives. She rakes her nails down his shoulders and Yoshi can feel blood swell up in her wake.
Her plump stomach rubs over his belly, shifting back and forth with her movements. Swollen and taut, just like it was with Miwa, only then...then she was not moving. Little lumps pulse and shift under the surface, stretching the skin until it seems on the verge of tearing.
"Here." She offers him a broken piece of bone and he laps at the marrow without tearing away from her dark eyes. There are black holes drawing him in, drowning him. (Oh, well. At least he won't be alone anymore).
The marrow tastes too sweet on his tongue. He eats it anyway, because somehow he is still hungry, even though his belly is full of torn meat and his fur is slick with blood
and there is a scrap of clothing tangled in his claws
He shifts his head and something crinkles under him. Shen hums and reaches down, fingers scraping under his back as she wishes out a little clump of bloodied green needles.
"Mistletoe," she says thoughtfully. "Must have fallen off the delivery truck." She smiles, glancing up into the darkness above their heads. "Funny, isn't it? All that talks about god and saviors, and then the world really came to an end on Christmas Day. Now the Kraang are just partying away."
She picks up another bone with her free hand and breaks it, the sound echoing in his aching brain. "Have you ever kissed someone under the mistletoe, Splinter?" she asks, lips glistening far too brightly.
He frowns. Has he? His thoughts feel sluggish and slow all of a sudden, twisted inside his skull. And...and Shen never called him Splinter, did she? She thought the nickname he'd received in the Self-Defense force was ridiculous
(And 'Shredder,' oh, that one made her laugh) 
She leans closer, her stomach pushing against his, and he doesn't want it anywhere near him, but his limbs have forgotten how to work. "No one's ever kissed me under the mistletoe before," she purrs, and there's something very wrong about her smell, something that chokes him.
"Shen," Yoshi rasps, and then, because he can't think of anything else to say, "Shen, where are the children?" He swallows, not able to look at her stomach. "The other children."
Shen smiles, and it's exactly as he remembers while not being anything like her at all. "Why, they're dead, darling." She breaks another bone and chews it thoughtfully. ""Or they just left, decided they didn't need you anymore. Does it really matter?"
Her finger brushes over his cheek. He can hear squeaking and scuttling ringing in his ear, can't decide if it's coming from around them or her stomach.
"You have us."
She puts a bone in her mouth and leans down to kiss him, grinding down his cock. Their lips touch, and the bones break in their mouths, filling Yoshi's mouth with meat.
He looks up, up at the mistletoe and something breaks inside him. Yoshi--Splinter--can feel it snap inside his head. He can hear the animalistic growl rumbling up around his throat as he grabs the body (which body, he doesn't know or care) and pulls it close, thrusting deep inside.
The darkness swallows him, and he welcomes it.
