Dog-sitting.
(Note from Author: Firstly, Fleur's lines aren't in a French dialogue, because what she says isn't very easy to put in a French accent. Secondly, hurrah for shameless PWP! and thirdly, thanks to Sam, my fellow pimp cane fan (arg) and also to Nikki, Amy, Ian, Callum and Tarl (for reading it and suggesting words). Enjoy!
"We have to go see off Harry, now, Sirius. Fleur will stay with you!" Mrs Weasley called, as she shut the door. Sirius and Fleur were left all alone in the big dark house.
"Oh, Sirius, I hate this place… I'm so scared" Fleur snuggled up to him for comfort.
"It's okay, I'll distract you… if you want?" he looked at her suggestively.
Fleur looked into his stormy grey eyes and melted "Oh… Sirius"
He took her in his arms and locked his lips to hers, so passionately, that she moaned quietly. He brushed his lips gently over her neck, and ran his fingers through her hair. He grasped her head and eased it back to shower her neck with kisses. He moved his hands down and unbuttoned the French woman's blouse, exposing he smooth skin and lacy bra. Sirius carried on kissing, down her shoulders and to her heaving chest. He paused, prohibited by her bra. He reached round and unhooked it. Fleur breathed raggedly and Sirius grinned at her slyly, kissing her again, his tongue entering her mouth, dominating hers. His hand slipped down and cupped her breast, massaging it. He slowly moved his head down to her other breast and gently sucked on it, using his tongue to arouse her nipple. Fleur moaned softly and put her hand on Sirius' head, stroking his soft, black hair and pushing herself into his mouth.
Fleur stopped writhing and pushed Sirius away, laying him flat. She crawled on top of him and unbuttoned his jeans, and tried to unzip them, but the bulging of his crotch forced her to become aggressive. Once the jeans were off, she ran her fingers down his chest and over his underwear that was almost bursting. She grasped his member and tenderly squeezed it. Sirius was growing impatient. He pushed her head into his crotch. Fleur ripped off the last barrier between her and her prize with her teeth. She bent down over his throbbing penis and enveloped it with her lips, moving them up and down his shaft slowly, rubbing her tongue all over it until it was fully hard. She clasped her hand around it, and moved it in synch with her mouth. Sirius gasped as she allowed the penis to reach the back of her throat and he knew he was going to come.
Suddenly, Fleur stopped, and undid her jeans, throwing them to the floor. She stood up and rolled her panties down her legs and kicked them to the side. She sat on him with her legs on the outside of his, and moved forward, lowering herself onto his manhood. She pushed herself up, and down, up, and down as Sirius moaned, and he started to push upwards too. He grabbed her torso and pulled her down so he could take over, thrusting hard and fast.
Fleur threw back her head and screamed with pleasure "Sirius! Oh god… Sirius!" Soon after she came, Sirius, panting and growling, gave one last thrust inside her, and she felt heat rush up within as his seed shot out. He pushed her off him, and just lay there, hot and sticky. Fleur stood up, her silvery blonde hair windswept and dishevelled. "I think we need to dress, Sirius. The order will be back soon." And she kissed him on the cheek, before gathering her clothes.
"Oh yes..." he replied, "let's just hope they don't come as soon as you did" and he winked and left the room, leaving Fleur feeling thoroughly confused, but satisfied.
