Wei Wuxian closes his eyes, letting Lan Wangji move his hand around his cock which can't seem to decide if it wants to remain hard or not. It's simply too hard to focus on the pleasure when he feels this strange intrusion, so Wei Wuxian doesn't try, imagining instead what Lan Wangji has told him.

Lan Wangji, his Lan Zhan, inside him, not his fingers but his cock. Even this Wei Wuxian can't quite imagine, a whole cock fitted inside where even a finger feels to large, but Lan Wangji...this he can imagine. The sight he'd make hovering over him, sweating and breathless, taking pleasure in the heat of Wei Wuxian's body. He groans, skin prickling with heat as he imagines being such a vessel. "How do I feel, Lan Zhan?" he asks. "Would I be good around your cock?"
