He's going to absolutely perish. Every thrust, every rub of Xichen's thick cock inside of him drives the thoughts from his head, one by one. He can't think of anything else but how full he is, how his body twitches and throbs in time with Xichen's.

His sense are filled with him. Mind, body, soul, he can't think of anything else. Guangyao eagerly kisses Xichen back, moaning softly in something like agreement as he shakily rocks his hips. He's too tired to really get a good rhythm, his own cock giving a tired, but valiant twitch. He can't get hard yet, but there's a pleasure ebbing and flowing through him like a wave he's riding. He can't tell if maybe he's come again or if he even stopped the first time, all of it swirling in his head like a fog.

The exhaustion seeps through skin and muscle all the way to the bone, making him whimper and rest his entire body weight against Xichen. "Yes," he murmurs in agreement. He was made for Xichen, made for this. While he might normally balk at such an idea, right now he can't even begin to remember why it used to bother him. "Only you. My body will remember only you, forever. You're ruining me for anyone else."

Not that there would ever be anyone else after everything anyhow, but still.
