Oh god it's been so long. Kind of hadn't been in the mood until the special aired the other day. Thought I'd come back with a late holiday surprise. I'll end it in this part. Though might continue in the future, exploring their relationship because we only got like 5 seconds of Peter Capaldi and I'm already in withdrawal.

Warnings for light bdsm.

"Who told you you could cum?" His voice was soft, low like velvet.

"I thought-"

"Nevermind what you thought. You're a bad girl River song and bad girls need to be punished." He slid his fingers across her folds making her shiver from the over stimulation, then down, somewhere else altogether. "It's been a long time since we did this? Hasn't it?"

River couldn't help but bite back a moan. His finger was right there teasing. He took his hands away for a moment and then she felt something cold press against her. How he'd hidden the bottle of lube she'd never know. And then his finger was entering her, slow and fast all at the same time. A pleasurable burn. Then it was two fingers, then three. Sher arched into him and bit back a moan. "Don't cum." He reminded her and she mewled in frustration.

He knelt and edged closer, his cock straining in the air. With one hand he kept her open and ready and with the other he stroked his cock until it was nice and slick everywhere.

River hooked her legs around his waist again trying to drag him in and this time he let her. She was more than ready for him.

For the briefest of moments he lost his composure. A low moan escaped his lips and then a soft growl as he sunk all the way in.

He kissed her breasts and nibbled at her collarbone until she urged him to move. And move he did. His rhythm became erratic. Now he was the one loosing control.

He paused and untied her from the headboard. "Turn over. Turn over. He gasped in her ear. She raised an eyebrow but complied and then he was taking her slowly from behind, his hands pressing, marking the skin on her back.

He gave her a small slap, loving how she felt when she flexed against the blow. River grunted against the pillows. "Do you like that? Should spank you for real one of these days."

But it was all getting too much for him now. He curved himself around her, pressed his head against her warm skin. He slipped his hands down her stomach and to her clit, massaging, getting them both right on the edge again.

"Say my name," he pleaded. "Say it, please."

She did.

"Again," he groaned.

She couldn't manage it though. It was long and difficult to pronounce, and she lost all concentration. She managed to gasp, "Doctor," just before she went over the edge.

"Fuck." he followed a few short thrusts after. He slid out and collapsed on the bed beside her. River turned to look at him.

He was panting softly, exhausted. His eyes were closed and one arm was pressed against his forehead. She stroked his chest.

"What's gotten into you?"

He flushed and stood up suddenly, leaving for the bathroom without a word.

"Doctor?"

She walked over to the bathroom door and knocked softly.

"Go away!"

She tried the door, expecting it to be locked, but it gave way. Apparently the Tardis was on her side. The doctor was sitting on the toilet. He pressed his head into his hands when he saw her. "I said go the fuck away."

River knelt down in front of him instead. "Tell me what's wrong please." She took one of his hands in hers and stroked it softly.

"I'm different."

"I've noticed."

He pushed her hand away at the remark.

"Sorry, sorry, I wasn't thinking. I just want to help." She pressed her hand to his and transmitted her emotions through their telepathic link. He relaxed a bit at that.

"I'm all fucking wrong." he protested. "See, I'm rude and I'm... rough... and I can't..."

"You're not wrong and if you hadn't noticed I enjoyed that."

"I just... I feel like I can't control it."

"You've just regenerated. You always took regeneration a bit bad. It'll settle down eventually."

"What if it doesn't?"

"If it doesn't it doesn't matter. I still love you and I'm sure people won't mind much. You'll still be you. You're still the doctor." she paused. "Was that why you wanted to hear your name. Hmm?"

He didn't reply but she knew the answer. She whispered his name in his ear, reassured him that was still who he was. She pried his hands away from his face and kissed him softly. "Come back to bed," she pleaded. "You must be tired."

He nodded, yawning, and followed. They turned off the lights and the ceiling lit up with a soft glow, a projection of a thousand stars. She rested her head on his shoulder and traced random words in Gallifreyan on his chest. Soft slow circles that lulled him to sleep.
