A lesson between the two would take time, more time than the two had in the moment within the tent. But perhaps Duncan could start with some basics. Many things could stir passion... Lust being one of them. And in the dance the two were tangled in at the moment, lust was certainly starting to rise within Duncan.
His body was reacting to the pleasure that Byron seemed to be getting out of their knife play, as he continued to lean over the other vampire, Duncan pressed his hips into Byron. "Aye... lessons perhaps." He began to speak but was cut short when the other man's fingers moved into the closing wound, pressing forward to cause more pain. His lips drew back from his teeth with a hiss, the blade in his hand made a quick and sharp cut along Byron's chest, opening the flesh above his left nipple.
"Nah, Sassenach, ye dinna want to see anger... not yet..." Duncan dipped his head down and ran his tongue over the cut along Byron's chest, circling around to the nipple and biting at it lightly. "Later..." He grinned before prodding his tongue into the cut and separating the flesh further, twisting his tongue and enjoying the feel of the blood that flowed more freely at the ripping wound.
