If Damon provided an alternative to lube, Ric would take it and take it gladly. Being inside Damon was part of what he wanted, right along with having some part of him -and blood was fine, thank you, especially given the comparatively long amount of time him getting fucked was likely to take- inside Damon. He wanted to... mark Damon back, and since that wasn't really going to happen, fucking was the next best thing.

And since he hadn't realized that was a reasonable possibility, touching would do just fine, with no regrets.

Until then, he shuddered a little at the fingers sliding over the back of his neck and holding him still, pushed back enough for Damon's foreskin to well and truly be out of the way when he dragged his thumb directly across the head. He also dug his fingers into Damon's ass just a little harder, just shy of something that would have bruised a human. He didn't care when Damon bit. He cared that Damon bit, eventually.
