"Snogging," she corrected him. "I refuse to shag you at your cousin's home. Don't
be weird."
"Moony could just find a date," Sirius said, ignoring her. "That way he'd have
someone to kiss at the end of the night. He could bring Mary. It might bother Peter, but―"
Cringing, Mia felt her hackles rise up. She regretted that she had not done more to
keep Sirius and Peter at odds. James, unfortunately, was all about friendship and loyalty
and had done his level best to patch things up between the Marauders.
"Peter needs to stay away from Mary. She never had any interest in him at Hogwarts,
and she says that she wants him to stop sitting next to her during Order meetings."
"Ah, give the boy a break," Sirius said with a chuckle. "It's hard for a bloke to get
over his first crush. Besides, Mary's better than that Slytherin bitch he was dating."
"Of course she's better. Mary is amazing, which is why she deserves better than
someone who breathes on her during meetings when he should be paying attention to his
orders."
Grimacing, Sirius nodded. "Fair point. I'll have a talk with the lad. Maybe if we set
up Mary with Remus.. ."
"I really don't think Remus wants to bring a date to your cousin's house and snog
her in front of... everyone," she said, cutting him off. "I know you want to see your family,
but I was hoping, now that Remus is probably gone for the night... We have the entire
flat to ourselves."
"Like company has ever stopped us before," Sirius said, his voice suddenly husky.
He surged forward and gripped her by the waist and lifted her into his arms, throwing her
high over his left shoulder with a laugh before carrying her off toward the bedroom.
Mia chuckled, feeling victorious in distracting him. "What about Andromeda?"
"She'll get over it. I'll owl her later." He smacked her arse with his open palm. "I've
decided to send 1978 off with a bang."
They did not make it more than a few feet closer to the bedroom door before Sirius
apparently remembered that they were now alone in the flat without Remus there to
accidentally walk in on them. In a flare of eagerness, he pulled her down from his shoulder.
Before her feet had a chance to touch the ground, he pinned her to the wall, his hands
gripping her arse tightly.
