'Watch yourself, Clara!' The Doctor called out to her. 'I don't think that's a stable surface.'
They had just managed to get away from some insectoid creatures and were heading back up the hillside towards the TARDIS. 'It's fine, Doctor. The rocks are a bit loose but they're holding up well.'
The Doctor looked up at Clara's progress, dodging the shower of loose pebbles. Why does she have to insist on wearing those skirts and tights, he thought. Especially when he's going to be looking up them. And just why does she have to have a nice looking behind. He bit his lip and started up the hill behind her.
'It's getting a bit slippy up here, Doctor.' Clara called down to him, grabbing hold of some scrubby brush to help herself up further.
'Don't get too far ahead.' He warned her even as he tried to not stare up her skirt. Trousers only, he thought. He was going to have to block the wardrobe options for skirts. 'Watch your footing there, Clara! That one rock doesn't look set!'
'It's fine, Doctor!' Clara said confidently as she put her foot right on the rock he'd been looking at. 'See, it's fiiiiiiiiiiiiiiiiiiiiiiiii..' Clara's words turned into a screech as her feet went out from under her. Sliding down backwards on her heels, her arms wind-milling to try to stop herself.
'Clara!' The Doctor cried out as she was toppling backwards right at him. Her body fell against him tipping him down the hillside himself, scrabbling about he managed to get hold of her and kept himself facing upwards to brace her fall with his own body. 'UNH!' He grunted as he fell hard against the ground at the base of the hill. Clara was on top of him, her back against him. Sweet blessed stars, he thought to himself as she squirmed against him to turn over.
'Doctor! Are you okay?' Clara managed to turn herself over to look down at him. Her knee caught him in the groin and he shot upwards, gasping in sudden pain and Clara's mouth was there and....
They kissed.
