Lan Wangji nods, half to himself before letting go of Wei Ying long enough to grab a pillow and stuff it underneath Wei Ying's hips, immediately pleased at the increased mobility for his hand.

He pushes in again, a little deeper but slowly and deliberately pushing over where he thinks that spot may be, other hand rejoining Wei Ying's to stroke him. "Wish Wei Ying could see what he looks like," he whispers, fingers curling and stroking him from within. "Debauched. Lovely. Mine. Warm."
