Five Times The Doctor Licked Rose Tyler
The first time was curiosity.
"What is it with you and tasting things?"
"It's just another way to experience things. Like touch or sight."
Rose stared at him in thought for a moment. "So why haven't you tasted me?"
He stared at her, dumbstruck, and she feared she'd crossed a line in the conversation, but then he grinned like a cheshire cat and leant forward, slapping his tongue in an upward stroke across her cheek. He smacked his lips once or twice as he pulled away as if trying to get a sense of the taste of her.
"What'd you do that for?"
"You asked me to"
"I did not!"
"You did so."
"I said no such thing."
"Well you asked why I didn't. That's practically the same as asking, isn't it?"
"No, it's not."
"So then you didn't want me to?"
"I didn't say that."
"I know. That's why I did it."
Rose stared at him, utterly lost for a moment before she started laughing. He just smiled at her and she was certain he was thinking he'd bested her, while she tried to think of some way she could get his inquisitive tongue tied.
The second time was necessity.
"Are you sure this is the only way?"
"Look, I'm telling you. The best way to neutralize Veron acid is the enzymes in saliva."
"You said best, so there must be another way. This is way too embarassing."
"Well I don't exactly carry Terigum powder around with me on a daily basis. Now bend over."
The third was for her.
Rose moaned and leant back, running her fingers into his hair to desperately hold him in place. The Doctor smiled, pleased with the results of his work. It seemed he had found the right spot after all. A little more experimentation and his companion was left incoherent, finally answering his question once he'd finished.
"Yeah. Right there."
The fourth was an accident. Really.
"Can you please not slurp that so loudly?"
"I'm not slurping. You slurp soup or some other liquid. This is licking. Liiicking." He drew out the last word while drawing his tongue across the alien confection-on-a-stick that he was holding.
"Well it's distracting me. I can't bargain if I'm distracted."
"Honestly Rose, what's the point to bargaining if you have unlimited credits?"
"I dunno. My Mum just taught me to never buy anything without negotiating the price. By the way, do you think she'll like this?"
The Doctor nodded absentmindedly, returning his attention to the sweet in his hand. He was wandering to the other side of the stand she was looking at when a cart ran by and he stumbled forward, knocking into Rose's shopping basket and falling forward towards her. As soon as they'd collided she shrieked and pushed him backward.
"You just got you sticky tongue all over my neck!"
"Yes, right... Well, you know, if that basket wasn't in the way I wouldn't have tripped."
"Tripped or not, I think you aimed for me on purpose."
"I don't believe you for a second." Rose smiled and the Doctor returned the gesture with a wink.
"Now, let's get that bazuleum back to your mother so we can get on with things."
There was no fifth.
