In my imagination, this is how Teddy Lupin and Victoire Weasley transition from friends to more.
It goes without saying that I don't own any part of the Harry Potter universe.
Chapter One
October 2015
Victoire had been Teddy's best friend for as long as he could remember. They had grown up together like cousins, except that they weren't cousins. They were just friends, best friends, and if he happened to have feelings for her that went beyond basic friendship, well, that was okay. Wasn't it?
"Teddy," Victoire said, jarring him from his thoughts as she sat down beside him on the grass next to the lake. "Are you okay?"
"I'm fine," Teddy said, smiling at her. He thanked her and took the bottle of pumpkin juice she handed him. He drank gratefully. It was uncharacteristically warm for an October day.
"It's so nice out today," she said, as if she'd known exactly what he was thinking about.
Teddy watched her lean back on her elbows as she stretched out on the grass. Her long, flowing hair shimmered in the bright sunlight. He blushed deeply when he realized that from his current vantage point he could see down her shirt just enough to get a peek at her bra. It was a pale pink color, and he tore his eyes away, ashamed of himself for looking. His throat had suddenly become very dry so he took a large gulp of his pumpkin juice.
"I wish it was warm enough to swim," Victoire sighed.
Oh, bloody hell, Teddy thought. That's all I need, to see you in a swim suit. You may as well just kill me…
Teddy spent the rest of that afternoon trying to forget about that pink bra, but even late that night, as he was lying in his four-poster in the seventh year boy's dormitory trying to fall asleep, the image kept creeping its way back to the front of his mind. He tried everything to distract himself. He tried thinking of the mountain of homework he needed to do before Friday. He tried listening to Dave's snoring across the room. He tried thinking of Quidditch drills to run next practice.
Despite Teddy's efforts, his mind continuously wandered back to Victoire's pink bra, which inevitably led him to begin thinking about what was underneath the bra. His arousal was quickly growing uncomfortable. He made sure the curtains were closed around his bed and pulled his underwear down just enough for him to wrap a hand around himself.
You're a pig, he told himself. You're a disgusting creature, totally ruled by your out of control hormones. If Victoire knew about this she would never even want to look at you again. Victoire…
He thought of her willowy frame, with gentle curves in all the right places. He thought of her otherworldly beauty, the perfect angularity of her face, her big blue eyes, her plump pink lips and her flawlessly white teeth. He thought of her platinum blonde hair that appeared almost silver in the sun's light, hair that he imagined fanned out over his pillow, or spilling over his hips and lower abdomen while she pleasured him with her incredible mouth—
Teddy stifled a groan as he reached his climax, panting heavily, his seed spilling over his stomach and his hand. He cast a cleaning charm on himself and pulled his underwear back into place, more ashamed of himself than ever.
