The Doctor looks up from the control panel and frowns. "Go brush your teeth."
"I have, three times." Amy huffs and slumps back on the jump seat, poking her tongue out in distaste. Then she has an idea. "Hey, let me suck you off."
The Doctor's hand slips on the lever he's pulling and his cheeks flush bright red. "What?"
"Come on, Doctor," Amy says, sauntering over to him. "Let me give you head." She slides one finger down his chest and abdomen, twisting her hand to palm him softly. "For the sake of my oral well-being."
"Oh..." He says, hardening in her grip as she nuzzles her nose against the sensitive parts of his neck. "Well is if for your oral well-being..." He bucks into her hand, then seems to think better of it. "No, no. Amy, this is a terrible idea. Go brush your teeth."
"Oh come on," She whispers, biting his neck gently, making him moan. "Please?"
Now that just isn't fair. The Doctor closes his eyes, Amy sinks to her knees and grins up at him. "Atta' boy." She encourages. She runs her fingers softly up his inner thigh and unfastens his trousers. Her nails scratch across his hip as she peppers kisses down his clothed stomach.
"Oh god."
"Just Amy."
He laughs, then groans as she pulls his cock out of his pants and licks the tip. Amy grins up at him, taking him deeper, enjoying his taste. She hums around him, closes her eyes and uses her tongue to lick away his pre-come.
"You taste so good, Doctor..." She teases, squeezing his arse playfully, pressing his cock further into her mouth.
He's about to respond with what would surely be a witty and well thought out come back when the TARDIS shudders and alarms begin to blare. "Amy!" He yells, pulling the monitor around to face him. "We're flying toward a supernova, you need to stop!"
Amy stops, for a second, to look at the console, "You can reach everything you need from here." and promptly swallows his entire shaft. He cried out, legs shaking and balls his hands into fists. She's not going to stop, he realizes as her hands fist in his trousers and she sucks down hard on his cock.
The Doctor takes a deep breath and flicks the sirens off. He pulls the zigzag plotter into hyper-drive and turns the helioplexteritor to north. Typing co-ordinates into the typewriter takes a little longer than usual with Amy stroking his inner thighs through his trousers and swallowing happily around his cock.
Finally the TARDIS stops shuddering and the Doctor starts, knotting his fingers in Amy's hair and-
"That was fun." Amy smiles, licking the come from her lips and standing cheerily. The Doctor bends over the control panel and pants.
"That was very irresponsible, Amelia." He says, tucking himself back into his pants and buttoning his trousers. "I think you need to be punished."
