This is how he likes Jin Guangyao best, he decides, loud and keening and unravelled. Unable to think. The hands in Xichen's hair aren't what make him lower his head to swallow down more of him, he does that of his own volition to be kind, tongue cushioning the length of Jin Guangyao as those fingers rub right over the same spot. Right there? Alright.

He glances over it on every other touch, always pausing when it seems like Jin Guangyao might get what he wants and retreating his fingers if he tries to chase them. That, paired with the way he idly hollows his cheeks to suck him down, is entirely for his own benefit because he very much enjoys it when his lover is begging.

But he never lets him come.
