Derek inched his way down the fragile expanse of creamy white skin, spotted with mouth watering birthmarks. His tongue lapped at the trail of pink his blunt nails had left down Stiles' chest and pressed open mouth kisses where they ended, right above the hem of plaid pajama bottoms. He couldn't resist the temptation to nip at Stiles' navel while his fingers fiddled with the elastic waistband. Derek sat straight for a moment, peeling his black v-neck over his head and chucking it to some dark corner in the room before leaning back down to ghost a kiss against the corner of Stiles lips.

He was wearing one of those lop-sided grins, not even bothering to hide it like he normally did when they were in such a heated moment.

"What?" Derek muttered, knees on either side of Stiles' hips who was now just gripping his stomach, as if the laughter was becoming physically painful.

"Nngh, it- It's just- your face!" Stiles sputtered out, wiping the tears from the corners of his eyes and peering up at the werewolf on top of him which only brought on a whole new onslaught of laughter that could be heard downstairs. Derek just peered at Stiles with the same 'What-the-fuck' and 'I'm-still-waiting-for-an-explanation' look he had perfected to be distinguised from his 'I'm-a-inch-away-from-snapping-your-neck' look. . Truthfully, they still looked practically the same apart from an eyebrow quirked upwards, but Stiles kept that to himself.

"You! You look so serious right now. I hope your dick isn't as stone cold as that stare!" Stiles exclaimed as the toothy grin and snorting laughter slowly began to die away, his hand raising from his bare stomach to hold Derek's jaw in his palm, thumb sweeping over his cheekbone. Affection pierced through his auburn eyes and suddenly, Derek wasn't pissed off anymore.
