Wei Wuxian leans in, brushing his lips along Lan Wangji's neck. He breaths in that scent, a mix of Lan Wangji's normal smell and the one this world has placed on him. He finds a good spot on the man's neck and kisses it first, gently giving it attention. His tongue comes out to swirl over it, wetting it and tasting the other man before allowing his teeth to sink in.

He sucks on the flesh as he bites down just hard enough to leave the mark but not enough to break the skin.
