Based on: "Such a pretty face, it'd be a shame to mess it up." and "I think you look pretty cute with a bloody lip. Don't make me do it again." from RP sentence starters, dark!Graves/Newt
The blow comes unexpectedly fast, and Newt feels how his mouth is filled with something disgusting, which tastes like iron, and he wants to throw up. The patch of skin just at his stomach level begins to sting and colors with an angry red. There's no much time before it will start to turn purple.
The blood floods out of his mouth as he coughs up and drips down his chin. His limbs, chained to the wall, tremble under the pressure of his own body weight. He tiredly raises his head, eyes focusing on Graves' tie as that takes out of his breast pocket a handkerchief and reaches to wipe at Newt's face.
Newt instinctively turns away, trying to escape the touch and squeezes his eyelids shut. He feels fingers grasping harshly at his chin and his head is turned forcibly back. Newt opens his eyes, blinking rapidly the tears from his lashes.
Graves looks into his eyes as his hand works to wipe the blood from his chin.
"I think you look pretty cute with a bloody lip. Don't make me do it again." He says and stops when there are only Newt's lips covered with the sticky deep red liquid.
Graves drops the handkerchief and tangles his fingers in Newt's curls. He yanks Newt's head back and Newt whimpers, hissing through gritted teeth. He's used to such harsh attitude, he expects only it from Graves - expected only it. So, when Graves leans so close they breathe the same air, when he brushes his lips against Newt's jaw, then moves them upper and seals on Newt's, kissing him fiercely - Newt can only stand here, shocked.
A moment into the kiss and Newt doesn't know what he wants: to draw back or to lean closer. The iron taste is still in his mouth and he's sure Graves feels it too, because he licks his way inside, exploring it with fervor. Newt moans into the kiss making Graves hum lowly in response.
It feels wrong, but it also feels so good, Newt barely can think at all.
Eventually, Graves withdraws and Newt opens his eyes halfway only to see how the man licks Newt's blood off his own lips and smiles darkly at him.
"Such a pretty face, it'd be a shame to mess it up." He says and grips at Newt's hair again. "So, you better start talking, Mr. Scamander."
