"You get a different speech, arsehole," James snapped. "My sister will not be
another notch on your bloody bedpost."
"So little faith in me, Prongs?" Sirius said with a light-hearted voice, but his eyes
had narrowed in annoyance at the fact that his best friend clearly thought so little of him.
Sirius wanted to tell James that Mia could have been his girlfriend a long time ago,
but he had sacrificed that potential for her sake. He tried not to think about that. His
reasons before had been sound, and they had not really changed. Had they?
It was moments like these that made him regret every one night stand and quick
shag in the broom closet he had ever taken part in. Sure, when it happened it was helpful
in burying the shitty feelings inside of him. Shagging Muggle-borns and half-bloods always
made him smile a little, as though he were somehow ruining the Black family name in the
process. The short, sweet moments he shared with random girls helped to make him forget
that he would eventually have to go to a home where he was constantly reminded of his
duties to his family. His family, who did nothing but tell him what a worthless piece of
blood-traitor trash he was. Good for nothing.
Well, Sirius knew that there was at least one thing he was apparently very good for,
and he had a long list of girls to verify it. Loudly. Multiple times.
Over Christmas holidays, his parents sat him down and told him they were in the
process of looking for his future bride. Suddenly, the scandalous nights with random
Ravenclaws stopped being fun. He had turned sixteen in November, and Walburga bitched
and moaned about how he should have been marked for the cause over Christmas, but
their guest of honour had business elsewhere. Sirius did not want to know who they were
talking about, but he knew exactly what they meant when they said the word "marked."
Most nights he struggled to sleep, dreading summer holidays when he knew he
would have to go home. Ridiculous days like Valentine's Day made him live in the moment,
forget that he would have to face the expectations of his family soon. He could be a stupid,
impulsive teenager, for now.
But James was quick to remind him that he could be neither stupid nor impulsive
with Mia.
"Fine. I won't fucking touch your bloody sister."
"Wow."
