This is from a tumblr prompt krysylyn86 asked you: Derek/Stiles, Derek makes up for Erica hitting him, first-time :)

'I am so sorry, so really very sorry baby.' Derek whispered crawling up the bed to loom over Stiles. Stiles huffed into his pillow, turning his face away. 'She's going to make it up to you, I promise you, she'll make it up.' Derek nosed his way up Stiles's neck, kissing his ear until he got to the bruised part of Stiles's head. 'Let me kiss it better.' Derek proceeded to kiss all over Stiles's face and head where Erica had thumped him.

'I don't forgive you.' Stiles said. He was sure Derek could hear the lie in his statement but he didn't care.

'Please.' Derek pouted, kissing down his jaw, and across to the corner of his mouth. 'Tell me where it hurts.'

'Here.' Stiles said pointing at his lips. Derek covered his lips, licking Stiles's top lip with the tip of his tongue, and then nipping the bottom one before leaving a filthy breath-taking kiss.

'Where else?' Derek asked. Stiles pointed to the bare skin of his throat and Derek happily obliged, following Stiles's fingers, stripping him slowly as he kissed wherever Stiles wanted him to. When Stiles was naked he rolled over and Derek kissed each plump ass cheek before running his nose along Stiles's crack. 'Is it sore here too sweetheart?'

Stiles shivered at the pet name but nodded eagerly and soon Derek's lips and tongue were soothing Stiles's hurt. 'Derek!' Stiles begged, pushing his body back against him. 'Derek please.'

'I'm kissing you better Stiles, it's a timely process.' Derek teased.

'I thought you were making up to me?' Stiles asked.

'I am.' Derek said.

'Then strip, let me see you.' Stiles said. Derek removed his clothes slowly, methodically, and soon he was covering Stiles with his naked body.

'I'm going to make sure my pack know never to hurt you ever again.' Derek whispered. His lips were hot against Stiles's ear as his fingers eased into his body. 'You're mine to protect, we'll show them.'

'Derek, please.' Stiles whined. Derek turned Stiles onto his belly, and eased his cock into Stiles's body. It was slow, tortuously so, with Derek putting almost his full weight on Stiles. He wrapped his arms under Stiles's chest, their fingers locking together, and turned Stiles's face towards his own. Derek's massive body covered Stiles's slimmer frame, and his movements were slow, but deep. Every push into Stiles's body had him gasping for air, every twist of Derek's hips had him gripping Derek's fingers in a vice grip.

His orgasm built slowly, curling around his nerves like a spicy smoke, burning him. He came untouched, only the blanket below them as his friction. Derek was moments behind him, his tongue and lips moving desperately against Stiles until they were both shaking and sated. Derek rolled off Stiles, and Stiles could feel his eyelids grow heavy. Somehow Derek cleaned Stiles without him noticing, and it wasn't until Derek was curling under the covers with him that Stiles realised he'd been drifting in and out of sleep.

'Shush.' Derek whispered his lips against Stiles's temple. 'Go to sleep now love.'
