Oh shit! McCoy made a muffled sound of surprise as the man was suddenly on top of him. Apparently playing with the beard was a signal he hadn't recognized, or misunderstood anyway. He'd thought it was just a little sexy, not permission to go hog wild! The spike of fear was unintentional and completely uncontrollable as he pushed gently at Obi-Wan, trying to turn his head enough to gasp in a breath and speak.

He didn't think the man would hurt him, not for a second, but McCoy wasn't ready to just have sex, and he didn't want Obi-Wan to do something that he'd regret either. The last thing he wanted was to hurt the man.
