A/N: Day 4 of Blackinnon Week!

Emprise

This was getting ridiculous. Sirius pushed his head into the wall of the library and groaned.

"Lily, lovely, lovely, wonderful Lily, why exactly are we studying when it's a gloriously sunny Saturday?"

"Well, James and I are studying, and you are not."

"Yes, because I wanted to have an adventure with all of us."

"Sneaking into Hogsmeade is not an adventure, Sirius."

"Sounds like one to me."

Sirius smiled at the new voice and turned to Marlene.

"I knew there was a reason we hit it off, McKinnon."

"Great," James waved them off, "You two go on your adventure and leave Lily and I to study."

Sirius rolled his eyes. James most certainly did not need to study.

"Are we adventuring or not, Black?"

Sirius smirked, "I'm always an adventure, McKinnon."

She laughed, "Lead on then."

Sirius motioned them out of the library and led Marlene to the statue of the one-eyed witch.

"I'm sure you know how to use disillusion charms?" He pulled his wand.

"Please," Marlene scoffed.

"Just checking," he winked at her before leading her into the passage that ran to Honeydukes.

"This is the kind of knowledge I stick around for, Black." She lit her wand and followed him.

"I knew it wasn't my looks you were after, it's this brain of mine." He smirked back at her.

"Of course," Marlene laughed, "I'm only around because you're full of secrets and I can't help myself."

Sirius reached out and flipped a curl over her shoulder.

"See and for me, it's because you're the fittest witch in the whole school."

Marlene smacked his hand away. "I'm changing my mind, I'm only in it because you're so annoying that I can't stop thinking about all the ways I'd like to feed you to the giant squid."

Sirius stopped below the trap door into the cellar and pulled Marlene into him. "All I heard, McKinnon, is that you can't stop thinking about me."

"Yes," she leant into him, "And how I'd like to orchestrate your fall."

"So you want me to fall in love with you?" He chuckled and pressed her against the wall.

"You are such an arse," she pressed forward and kissed him.

"For that, you can buy the first round," Sirius murmured as he kissed her.

"And you can buy the second," She ran her black nails against his scalp and smirked against him when she pulled a moan from him.

"But of course, McKinnon," He kissed down her neck, "But first, I have something to finish."

He'd promised her an adventure, after all.
