“Reg, we need to talk. Brother to brother,” Sirius said with a grave expression on his face, pulling Regulus to the side in the corridor.
Regulus nearly shit himself.
“Whatever for?” he asked cooly, trying to keep up his unbothered demeanour as he internally panicked. Had Sirius already found out? Had Potter told him? Merlin, he was going to kill him if he did.
Sirius adopted an expression of sympathetic superiority. “Listen. There comes a time in every young man’s life when he needs to learn certain…spells. Spells that are maybe not taught in classes. Spells that he might learn from his devilishly handsome and ridiculously intelligent older brother, for example.
Now Regulus was confused. Sirius knew about Regulus and Potter and he was….giving him the sex talk? That was not what he was expecting.
“You’re trying to teach me protection spells?” he asked, furrowing his brow in utter astonishment. “Like…for shagging?”
The older boy balked. “What? No! Fuck, absolutely not! You’re far too young…are you…wait tell me you’re not?”
Okay, so this was not what Regulus thought. “No!” he quickly answered. “No, I just…Are you talking about J–what’re you talking about?” He decided it was best not to make any more assumptions. Perhaps Sirius was going on about something completely different.
“Love bites! Reg, you’ve got a massive hickey on your neck! Listen, I’m proud of you for getting with whatever crazy bird did that to you, but damn, you need to hide that mark!” Sirius explained, looking a bit scandalized.
And Regulus was scandalized, too. “I–what?” he demanded, jaw dropping.
But as soon as Sirius held up the mirror he conjured, Regulus could see: a purple-red bruise on the column of his throat, clear as day. “Fuck!” he gasped. He needed to kill James Potter.
He also needed a favor from Sirius.
“How do I cover it?” he demanded, pouting just a little.
Sirius beamed. “Never fear, Reggie. I’ve got you.”
He proceeded to teach him the perfect spell, completely unaware that he was helping him cover a mark made by his best friend’s mouth. But they were successful in hiding the bruise, and Sirius clearly felt helpful, which was the point, anyway.
What Sirius didn’t know wouldn’t hurt him.
