The permission, however silent, is what pushes Lan Wangji over the edge. The feeling of Wei Ying's hand on his hips, pushing them up, allowing Lan Wangji to take his pleasure is so good and so freeing that he is only partly aware of himself thrusting up one, two more times before he breaks.

The pleasure is wrung out of him, out of the deepest parts of him and it makes him feel wild, makes him want to pin Wei Ying to the floor, thrust against every soft part of him. It makes him want to take and be taken in ways he still doesn't fully understand how to do. It makes him want to scream out and he only just manages to shove his wrist inside of his mouth and bite down before he can summon all of their far too close neighbors. It is all of those things at once unless he is suddenly boneless and collapsed on the bed, teeth still clenched around his arm.
