He was never going to last long after forstalling his orgasm once already, and the sudden burst of spiritual power flooding his meridians in conjunction with that hard, penetrating thrust is nearly enough to send him over the edge; he'd wondered, on those few occasions when he'd allowed himself to indulge in fantasies about having Lan Xichen in his bed, what it might feel like to dual cultivate with him, but though he has had occasion to experience the sensation of receiving Lan Xichen's qi in the past, nothing could compare to this intimate sharing. Jin Guangyao makes a sound like a choked moan and drops a hand suddenly to clutch at Lan Xichen's wrist, his fingers seeking out his pulse point to create a closed circuit of energy. (He knows that nothing he could ever pour back into the peerless Zewu-jun could ever compare to his Er-ge's own exquisite qi, but he shares it anyway. Anything he could part with, he would part with gladly for the man beneath him.)

"...until the only thing I knew was your name--"

"Xichen--" Jin Guangyao doesn't have time to warn him beyond that weak, choked gasp of his name into his ear, before he spills himself between their stomachs, untouched beyond the slide of his cock against Lan Xichen's skin. Each pulsing wave of pleasure has his hips stuttering forward, rough and uncoordinated, until he's spent himself to completion, but he doesn't give Lan Xichen the chance to slow down. "Don't stop," he breathes into his ear, his voice as low and raw as the rest of his body is limber and pliant in Lan Xichen's arms, and buries one hand in his ink-black hair. "Don't stop--fuck me like you want me to fuck you, Er-ge, show me."
