“Bite me.”

The hand he had held out was smacked away, and he couldn’t contain the angry growl that escaped between his fangs. Sure, he’d been picking on her, jabbing her in the thigh with a bony finger and making shitty fat puns. He had continued even after she told him to knock it off, too. He was being an asshole.

…But the bitch decided to turn on him, actually fight back?

The sheer heat that coursed through his marrow at the idea sent a shudder down his spine, and his still outstretched hand curled into a fist.

Fuck, that was hot.

He was able to get such a bleeding heart mad enough to talk back, and he was feeling a little high from it.

“Heh… alright then,” he muttered, voice flowing with an undercurrent of a growl that he could see affected her beautifully. Her already anger-reddened cheeks turned an even darker shade, until her freckles began to blend into her blush, and he could smell the beginning traces of her arousal.

‘She said ‘bite me’…’

Lena made a small confused sound as Fell shifted closer, returning his arm to its prior place around her shoulders, but the confusion lasted only for a second.

It was dashed as he leaned heavily against her side, nudging her hair out of the way with his nasal bone before unhinging his jaws.

She felt a sharp sting as teeth sank into her skin, a startled moan spilling past her parted lips just as the tiniest bit of blood spilled past his fangs.
