A/N - Jack is back! And you have to have a bit of a dirty mind for this one...
Disclaimer - I don't own Doctor Who.
"Oh, God, Jack. That feels..."
The Doctor stopped outside of Emma's bedroom, brow furrowed. Hearing a low moan, he pressed his ear to the door.
"How's this?"
"Yes, right there!"
A laugh. "Emma..."
"Mmm, Jack, harder. Put more...yes!"
His eyes widened in realization. "No!" He burst through the door, expecting to see the two all sweaty and disgusting. "You two stop it right now! You are not..." The sentence died on his lips when he saw them. Emma was seated in a chair with Jack behind her, his hands on her shoulders. "You...you're massaging her." He sagged against the door jamb, relieved.
"Of course. What did you think I was doing?" Something flashed in Jack's eyes as he dug his thumb into Emma's spine, getting another moan out of her. He grinned at the Doctor's scowl.
"Doctor," Emma breathed out. "you need to get massaged next. He's brilliant."
"Yes, well, maybe another time. I have to fix the TARDIS and all that." He growled, spinning on his heel and storming out of the hall.
"What's wrong with him?"
Jack smirked. "No idea."
A/N - Ah, I only have so many ideas left inside me. I'm definitely taking requests now.
