[ There is no reason why Lan Wangji's words should be so hot, yet his cock jumps at the word consummation and he looks at him, a little wide-eyed, flushed and eager. It's true that before tonight, that wasn't on his mind. Anytime he touched himself... well, no, he did think of Lan Wangji during those times but not in this context. Not in the idea of consummating their marriage, not when it'd all been for show beforehand. (Or still is? Except now they're adding to it, giving themselves more to... indulge in.)

His back arches, toes curling, cock pressing up into Lan Wangji's slow strokes and he whimpers. He's played with his hole before when he's masturbated but he's never had anything inside him. Now, the thought laid before him, he feels impossibly empty and wants to feel Lan Wangji in him, fucking him, filling him with his seed. It's all so erotic that Wei Wuxian gives a shiver and breathes out heavily. ]

Please. Lan Zhan — husband. Please. Fuck me. I'll do anything you want, I'll make you feel so good. [ He babbles a little, overwhelmed, cock leaking pre against Lan Wangji's hand. ] I've never — you'd be my first.

[ Which, duh, he already knows that but Wei Wuxian is a little worked up at the idea of it. Pupils blown, cock hard, face flushed, he just wants. Lan Wangji's already been his first kiss, his first handjob, his first everything so far. Now he wants him as his first time. ]
