Written for Screaming Faeries' Pairing the Character competition for the Sirius Black round. If you need a more concrete time-frame for it, I'm imagining this took place around 1979 or 1980.
Sirius let out a soft sigh as he woke back up. The afternoon sun filtered through lacy curtains, and he smiled as he realized he wasn't in his flat.
"Morning."
He turned to the side, taking in blonde curls, a pair of brown eyes, and a rather dirty smirk. "You know I don't think it is. Seems a bit later than that."
Marlene glanced over at the window before shifting to nuzzle her head into Sirius' neck. "It seems we fell asleep again."
"I thought this morning was worth a nap after." Sirius chuckled, wrapping his arm more tightly around Marlene. "What time is the Order meeting?"
"Seven," she answered without moving her head. "We've got time."
"Have we?" He grinned and leaned down to kiss her nose. "I was supposed to meet James ahead of time, but I don't think he'll mind being stood up if it's for a good cause."
Marlene laughed and prompted herself up on one arm. "You're incorrigible? What am I going to do with you?"
"Keep me?"
Sirius leaned in for a kiss, which Marlene accepted.
Letting out an overdramatic sigh, she grinned. "I suppose I'll have to. After all, someone needs to keep an eye on you."
"How about some hands too?"
