"Rose Tyler," he slurred, "'ave I ever told you about the time I drank a Vodarian under the table? And, you know, they can 'old their booze. 'Course, after I shamed 'im, 'e wanted me dead, but that's beside the point. The point is..." he stopped walking abruptly, a blank look on his face. "What was the point?"
Rose caught up to him, stumbling slightly and giggling. "Doctor, you told me that story about four hours ago, before we hit the pub, and the point was that you stopped drinkin' cos a Vod...Vod-...Vod-thing almost killed you cos if it."
"Oh! Tha's right! Well fat lot of good that story did me! Rose Tyler, I think we're slightly intoxicated. Inebriated. Merrily under the influence of what translates to "little water" in Russian. That's vodka, mind you," he added as a side note.
"Doctor," Rose interrupted. "You're a bit drunk, yeah?"
The Doctor burst out in a fit of very un-Doctor-like giggles, and threw an arm around Rose's shoulder. "Oh, sort of, yeah."
Rose giggled again, and the Doctor thought, through the drunken haze in his mind, that it reminded him of wind chimes. "I think we 'ad a bit more than vodka, Doctor."
"Right you are, Rose; don't ask me to pronounce it right now, though. If I couldn't even say raxi-raxacorko-rax-rax-"
"Raxacoricofallopatorius?" Rose interrupted.
"That's the one!" He looked at her in mock awe. "Are you sure you're drunk, Rose Tyler?"
"Oh, I think I'm drunk enough," she replied lightly.
He entwined an arm with hers, both of them swaying with the sudden change of position. "How drunk is drunk enough?" he asked slyly.
"Oh," she stopped and turned to face him, looking up into his eyes. "drunk enough for this." She placed her hands on the sides of his head and pulled him to her in a kiss.
For a moment, he didn't respond, and Rose dreaded that she had made a mistake. However, after that moment, she felt him step closer and place his hands on top of hers.
His lips parted and he kissed her back very chastely, for being intoxicated. He let his hands drift down her arms to her shoulders, and then down her back to rest on her waist.
Rose deepened the kiss, running her fingers through his hair. She felt his tongue tentatively brush her lower lip, and she opened her mouth invitingly.
His tongue slid into her mouth gently, and they each explored the other's mouth, running tongue over tongue and lips.
The Doctor broke the kiss, but didn't move away. Rose felt his lips curl into a smile against hers, and she grinned widely.
"You kiss well when you're drunk," she teased.
"Imagine when I'm sober," he replied, winking. "Now, we have one small problem."
Rose stared blankly. "What?"
"I've no idea where I parked the TARDIS."
