They act on their feelings

The Doctor entered the TARDIS, Clara following closely behind. The doors closed behind them.

"Doctor, I can explain," Clara started. "I was.."

"No need," The Doctor interrupted. "There's only one thing I want to know."

"What?" Clara replied uneasily.

"Who were you thinking about?"

"No one..."

"Come on, you must have been thinking about someone."

"I wasn't..."

"Was it me?"

Clara blushed. "It... it might have been."

The Doctor smiled. "Do you want to experience it for real?"

"What??"

"We know you want it, and I want it too."

Clara took a deep breath. "Okay. Let's do it." Clara peeled her soaked knickers down and off, and tossed them to the side.

"Follow me." The Doctor said, and led her down the steps and down a hallway. He opened a door, and they entered into a small room with a double bed. He turned around. Clara slowly stepped towards him, placing her hands on his belt. She gently unbuckled it without a word, pulling it cleanly out of his trousers belt loops. She undid the buttons and unzipped the trousers, pulling them down and exposing his black boxer briefs. The material was stretched by a prominent bulge.

Clara tugged the Doctor's boxers down, and nearly gasped. "Jesus christ… it's bigger than I imagined." She grasped it and began gently stroking it. The Doctor let her, as he stroked her hair. "Doctor, I want it in me," Clara said.

The Doctor nodded. Clara got up on the bed on her hands and knees, and positioned herself for the Doctor. It wasn't long before the Doctor was behind her, and his cock was pressing against her entrance. "Please," said Clara.

Clara felt the Doctor enter her. "Ohhh... fuck that's good." The Doctor began thrusting slowly to start with, then gradually sped up.

"Oh god don't stop."

"Jesus fucking christ."

Clara's hips were rocking back and forth, her tits swaying to the same rhythm. "Keep going Doctor, as hard as you can!"

The Doctor was panting now. "Clara, I'm very close now. But don't worry, the TARDIS will stop it having an effect."

"Good, because I want it inside me. I want you to fill me up."

It wasn't much longer before Clara felt her orgasm coming soon, for the second time this day. But the Doctor beat her to it. "Clara, I'm coming," he breathed, before letting loose. Clara felt his seed inside her, and in response she came too.

"Oh my god..." she exclaimed.

Clara and the Doctor lay side by side on the bed, utterly exhausted. She turned to face him. "That was amazing," she smiled. The Doctor smiled back.

Note to self: maybe that was't such a bad idea after all.
