Proximity for Dex and cannibal!reader is so important but sooo risky. There’s so many layers of trust that go into him letting you put your mouth on him, even when you first start seeing each other he’d leave you with fresh bites on his kiss swollen lips, bleeding from the little punctures where you had subconsciously nipped him a bit too hard, lost in the feeling of his mouth on yours and the taste of his skin. He has to work you up to it, get to a point where he knows you can have him in your mouth without ripping apart his flesh with your eager teeth, pressing the pads of his fingers against the expanse of your wet tongue, letting you suck and nip at those, hushed reminders to be gentle rumbling through his chest when your teeth drag a bit too hard, the hazy conspiratorial glint in your eye subsiding. He would be lying if he said he didn’t enjoy it, the thrill of having your teeth graze his skin, ultimately knowing the restraint you have to possess to leave him breathing.
“Mm–easy, easy,” he’d murmur, thumbs soothing the curve of your hinged jaw, heavy cock resting on the twitchy flat of your tongue, fingers pushed against the strands of hair that would otherwise fall over your face. Your wet lips suckle on the blushing tip, beading precum spreading against your tongue, the sight makes a stuttered breath shakily pass Dex’s lips. The taste of him overwhelms your senses, glassy vision sweeping your lashes across your cheeks in fluttering blinks, sinking your mouth further down the length of his cock, humming around him. “Oh,” Dex can’t help but moan, head tilting back, eyes falling shut, swallowing thickly, “Yeah, yeah, just like that. Such a sweet mouth on you, hm?” He should expect it when he feels the blunt graze of your teeth against the side of his cock, lightly dragging down the vein that trails the underside of his length, a low groan leaving his throat as his hips hunch forward into your mouth, a soft twitch curling up the corner of your lips. Watches you pull your lips off him, open mouth kisses pressed down the side of his cock, light bites soothed by your soft lips, eyes peering up at him with each bare of your teeth, feeling him tense underneath your roaming hands on his thick ridgid thighs, “Jesus. You wanna eat me alive, don’t you, sweetheart? Ah—fuck,” his curl up, lopsided grin followed by a rumbling moan, hips stuttering up into your palm as he chases his release through the graze of your killing jaws.
