It can be so very easy to rile Lan Wangji up, subtle as it may be to begin with. Wei Wuxian knows he has just that much of a hold upon him. Even after so long, there's a level of both excitement and smugness, even accomplishment, when he succeeds in doing so, and that much more.

It especially feels this way when Lan Wangji moves forth once again. He's hyper aware simply with slip of his clothing over the heat of his body, so much so that Wei Wuxian draws that much closer, shifting his leg inward. The gesture this time has him pressing in harder, likely making it a challenge for Lan Wangji to work his shirt off. But he really can't help himself. Due to a few certain decisions he made, more specifically when he excused himself to the bathroom earlier on, which Lan Wangji will discover soon enough, it's quite obvious through the otherwise thin material of his boxers. The movement is enough to momentarily break the kiss with a shuddered gasp. Not even thinking about what Lan Wangji is doing to his clothing, both of his hands move down to grip his husband's ass, pulling him in, while at the same time grinding forward tightly.

Reaching up with one hand, he tugs on Lan Wangji's forehead ribbon, intentionally slow, before it loosens and slips from his fingers.
