A/N: After getting such good feedback, I decided to add another chapter on. Just more smut, so if you aren't over 18, go away!

It was all she could think about.

That lever.

They had spent the day suspended in the Time Vortex, as the Doctor attempted to make some much needed repairs to the TARDIS. Clara was sat in a seat, feet up, reading a book. But that didn't stop her from noticing that every time the Doctor passed by the lever in question, he would run his hand over it, glance in her direction, and smile. Every time, Clara could feel her cheeks blushing a darker shade of red.

Now it was late at night. The Doctor had retired to his room, and Clara was supposed to be asleep.

"Busy day tomorrow," the Doctor had said. He didn't know why it was going to be busy, but he assured her that it would be.

But, instead of sleeping, Clara was under her covers, hand between her legs, rocking backwards and forwards to try and bring herself to completion. Her fingers rubbed back and forward over her clit, her breathing was laboured, her eyes squeezed closed. She was so close. Her hand that was not busy between her legs moved up to pinch her nipple. That little bit of pain would surely do the trick. Her toes curled, her mouth open, then…

WAAAAAAAAAAAAAA! WAAAAAAAAAAAAA!

Clara froze, eyes opening to a flashing red light enveloping her room as the loudest siren she'd ever heard blared through the TARDIS. She didn't know what caused it, but she was cursing whatever it was as she felt her orgasm fade away, just out of reach.

"Clara! It's okay! Don't panic!"

The Doctor flew into her room, sonic screwdriver in hand. He had a blue dressing gown wrapped around him as he stopped in her doorway.

"You don't look like you're having a heart attack."

Clara blinked. "What? Of course I'm not having a heart attack? Why would I be having a heart attack?"

The Doctor frowned.

"Well, because the heart attack alarm is going off."

"The heart attack alarm? You have a heart attack alarm? Why would you have a heart attack alarm? And what makes it think that I'm having a heart attack?" Clara was fuming. All she wanted was to cum in peace, and that was not apparently going to happen now.

"Well," said the Doctor, running his hand through his hair, "It is set up to go off if your heart rate suddenly changes and I'm not there. An alarm goes off so I know to come and help. Were you doing something that may cause a sudden change in your heart rate, Clara?"

"For fucks sake," Clara muttered. She sat up, letting the duvet fall around her waist, and the Doctor tried not to look at her naked breasts that were suddenly exposed to him.

"Yes, Doctor, there was a reason my heart rate suddenly changed. If you must know, I was masturbating."

The Doctor's eyes widened. If Clara wasn't so frustrated, both generally and sexually, she would have found it amusing. However, she was still angry, so she just carried on.

"This hand," Clara stated through gritted teeth, "Was between my legs, rubbing my clit. My other hand was squeezing my breast. I was just about to cum, when your stupid alarm went off."

She smiled slightly as she delivered her final sentence, looking him straight in the eyes.

"You owe me an orgasm."

The Doctor blinked. "I'm sorry, what?"

"You," Clara said, lying back on her bed, "Owe me an orgasm. You're the reason that I am like this."

With that, she kicked the covers off, showing him her naked body. There were juices running out of her clenching pussy, and running on to the sheet below her.

"I, erm, I…"

The Doctor looked down her body, before coming back up to meet her eyes. Although he seemed hesitant, Clara could see the bulge in his dressing gown which suggested he was definitely interested. She gave his crotch a pointed look, and the Doctor slowly undid his robe, letting it drop to the floor. He climbed on to her bed, and leant down, quickly running his tongue between her pussy lips, before his teeth nipped gently at her clit. Clara screamed as an orgasm immediately washed over her. But it seemed that the Doctor wasn't yet finished, and he forced a finger into her clenching pussy, and felt her squeeze his finger as he sucked at her clit, running his tongue over it repeatedly. Clara's back arched, her hands reaching down to grab hold of the Doctor's hair, and she pressed his face into her centre as she rocked her hips against his talented mouth.

Three intense orgasms later, and Clara weakly pushed him away.

"Too much," she panted. The Doctor moved up the bed and pressed a kiss to her lips.

"That okay?" he asked.

Clara smiled at him as she felt his erection pressed against the side of her leg. Once her breathing had returned to normal, she felt her arousal building up inside her again. Wordlessly, she encouraged him to sit next to her, his back against the wall. She swung one leg over him, wrapped one hand around his cock, and guided it into her pussy. Sat on his lap, her breasts pressed against his chest, they both moaned as she began to rock against him. The Doctor let her take control for a little bit, before he gripped her hips and helped her slide up and down him. As she moved faster and faster, the Doctor leant forward, took one breast in her mouth, and started sucking. The new sensation caused Clara to cry out, and didn't even notice that one of the Doctor's hands had moved from her hip.

Until that hand started rubbing her clit, that is. Then she definitely noticed.

Clara's walls clamped down around the Doctor as yet another orgasm washed over her. The Doctor wasn't far behind her and thrust into her one more time, crying out as his release poured into her.

Both panting, they lay down next to each other on the bed.

"Will you do me a favour?" asked Clara.

When the Doctor nodded, Clara made her request.

"Please disable the heart attack alarm."

"Are you kidding?" replied the Doctor, breathlessly. "If this is the consequence, there's no way that I'm turning it off. Although, it does only go off when I'm not with you."

Clara raised her eyebrows. "So, are you saying that for me to have an uninterrupted orgasm, you will have to be in the room?"

Closing her eyes, she decided.

"If this is the result, then that is fine by me, Doctor."
