"One of the lesser known qualities that the Blacks share," he said, trying to keep a straight face. "They will, but don't rush. It's pretty nice when it's all new. It gets better with experience, but there's something that you can never have again.
Regulus laughed. "It's very ironic when you tell me not to think. You're one of the most serious people I've met, and I don't care that it's my brother's name. The word fits."
He snorted. "Oh, I hope sex will have a lot to do with this. I like sex. I really, really do, even if I don't like sex with people I don't know in rooms with others." He shook his head. "It's nothing bad, but it's something that could be used against you if you don't know the truth."
He took a deep breath because he knew that Severus would not be pleased, but he also knew that once Severus found out why he wasn't going up to his rooms to sleep, there'd be questions. "I spend some of my nights with Severus. We're friends. There's no sex involved, but I sleep there. It's just... if I stop, he's going to figure out why, and you know him," he said with a smile. "He'll say something in the possible worse way, so I thought you should know in advance."
