Okay, this works, too, he thinks as he lands on his back on the bed, letting out a sigh of pleasure as those teeth sink into his neck. As much as Huaisang likes being the one to do the biting, he's enjoys being on the receiving end of it, too, especially when it's the man he loves marking him for his own.

"Yes, good, A-Cheng," he purrs, dragging his fingers slowly up along the other man's spine and the back of his neck.

"You can bite harder, rough me up if you want."

He'll just have to try to keep quiet so no one gets too curious. But at least, they're not in Qinghe when Huaisang's screams might result in an overprotective Nie Sect cultivator kicking in his door.
