Hot Banana
The Doctor was preparing their favourite mugs for their morning cuppa when he suddenly felt a pair of arms encircle his waist and (even better!) a pair of warm, soft breasts press against his back. Rose's clever hands deftly slipped under his shirt and began to finger the strip of hair on his abdomen, following it down to his waistband. He groaned (in a very manly way) as she dipped one hand even lower, while the other nimbly undid his trousers.
"Hot banana, Rose!" he hissed, and spun around in her arms, grasping her beautiful face between his hands, and drawing her in for a long, slow, passionate kiss. Her soft lips pressed firmly but gently against his as her tongue (oh, that gorgeous, little pink tongue!) stroked his bottom lip seductively.
They pulled away from one another. "Hello," he murmured his voice hoarse. He gazed down into her lust-darkened eyes, and further, down to the curve of her bare breasts.
"Hello," she returned, flashing him her most sinful version of her tongue-touched smile, causing the already obvious evidence of his arousal to strain uncomfortably against his trousers even more.
She took a step back from him, biting her bottom lip as her eyes flicked between his face and the growing bulge. "I found your pants," she gestured to the pair of TARDIS-blue boxers, patterned with bananas, which she was currently wearing, "in my room this morning. And," the tongue appeared again, "I was wonderin' …"
"Yes, Rose?" he swallowed thickly. By all the gods he didn't believe in, he was helpless when she was near.
"Well, I was wonderin' …" she reached out a hand, cupping his erection through his trousers.
"Rassilon, Rose!"
"… If I'm wearin' these …" she began to stoke him with firm steady pressure, "… then what have you got under these trousers?"
"Hot banana, Rose!" he replied with a squeak. Grabbing her by the hand, he pulled her back to her bedroom, "Hot banana!"
