Remus sighed softly, rubbing his cheek against Regulus'. "I love this, too. I just...I don't know. I'm disappointed in myself, I guess. I thought I was helping and I was only making things more confusing."
Staring into Regulus' eyes, seeing the grin, it would have taken a man with more willpower than even Remus possessed to keep from smiling in response. "That was all of me," he said, fingers toying with the ends of his lover's hair. I may have staked a claim on you. But, in doing so, I gave you everything of myself."
Tell him about the werewolf? Remus bit his lip, thinking how best to describe what he felt to Regulus when he wasn't even sure how to describe it to himself. He chuckled at the last thing Regulus said, though. "That may be a problem, then. A very big part of these feelings is an almost primitive need to satisfy you, to prove myself through your satisfaction. Even the fight with Harry, the demonstration, tapped into that in a way. It's part of why it felt so devastating to have disappointed you. It's more than just being a nice guy and wanting to please my lover. It's almost a need of it's own. And it's all tied up with the possessiveness.
"The other night, when you tried to make me jealous over Severus, I kissed you. And that's what that was, needing to prove you were mine and that only I could get that sort of reaction from a simple kiss. The bites and marks wouldn't be half as appealing if you didn't enjoy it. There would still be the desire to see you 'branded' as mine, wanting that permanent mark. The smaller bites, fingermarks, bruises...I like them, but in large part because you enjoy them so much. Your pleasure, seeing your eyes almost glaze over when I touch one..." He trailed off, ending in a quiet growl as he leaned up to capture Regulus' lips in a kiss.
"It doesn't feel like 'control', though. Control is cerebral, it's rational and thought out. 'The werewolf' isn't about anything but instinct and desire and not getting enough of your body and feeling like if I can just touch you, taste you, just a little bit more, then everything will be all right; if I can just hear you come undone, see the bliss on your face when you come because of me, then I'll be satisfied."
