Laundry Day by Luvscharlie
Warnings: Sibling incest, unwitting voyeurism, oral
A/N: Originally written to work my way through a writer's block, where my prompt was incest and the drabble had to be 100 words exactly.
Ginny'd never imagined putting away laundry could be so enlightening… or terrifying. But really, that's all Ginny'd planned to do. She'd never expected to discover- well, what she saw when she opened the door to her sons' bedroom door was undeniable.
They really had been doing that.
She didn't think they'd seen her. Al was concentrating intently on sucking James's cock down his throat; James's eyes were closed in ecstasy.
"So what did you do today?" Harry asked over dinner.
"Just laundry day, you know."
"Sounds boring."
"Not nearly as boring as you might think," Ginny said, eyeing her sons.
