How he had grown comfortable enough with Regulus to be sitting here, arms around each other, exchanging gentle kissing and friendly teasing, Remus had given up trying to analyse. For once in his life, he was just enjoying things as they came.
"I want to enjoy the experience, enjoy the little thrill of knowing it's okay to do this." He kissed the other man gently. "But, despite the blushing, I'm not made of spun glass. I'll tell you if things are too fast. I just don't want you to feel you need to be overly cautious about it or with me."
Shaking his head, he smiled wryly. "Now who's being optimistic?" Remus didn't care how nice Severus was to Regulus. He didn't want the other man turned into a rope in some personal tug of war just because he could get along with the both of them. But, he'd let it go for now.
