His arms pulse with power, it's a vibration that beats from his veins to his chest, to his abdomen and then lower.
Oh, Zhongli thinks. This could be an issue.
Xiao's breath is wet against the inside of Zhongli's wrist and his eyes dance from the amber glow of Zhongli's arms to Zhongli's eyes, and Zhongli sees pure lust in those irises. It's something he knows Xiao rarely voices out loud, even during moments like these, but it's always there for Zhongli to see. Every thought of the yaksha, naked and clear like his body, beneath Zhongli's own. It feels like a form of worship Zhongli didn't know he could experience when Xiao nuzzles his wrist, then licks it like a timid animal but the way he keeps their gazes locked when he does it, is far from timid. His eyes turn even more molten, stormy, when he moves his fingers across Zhongli's arm.
He can feel it too, the way Zhongli holds himself back.
"This time," Xiao says. "Just take. Take me."
Zhongli knows better than to question him, Xiao's expression and layer of sweat on his flushed face tell him all he needs to know about the sudden shift of mood, of Xiao's desire. Zhongli kisses him, silently telling him that way that Xiao's desire is his own as well. The fire that burns inside him, only for Zhongli, is Zhongli's fire for him as well.
He thrusts up, slowly and deeply. Xiao's whole body shudders underneath Zhongli's and the kiss turns messy in their need to not break it. Xiao's breaths against Zhongli's lips and tongue are exquisite like a sip of blessed spring water. He's warm, almost too warm around Zhongli and it feels right. Being surrounded by Xiao, inside Xiao, feels right and nothing can compare to that feeling. He pushes out and in only couple of times before he stills and grinds upward inside Xiao.
Xiao turns his head to the side and lets out a broken scream. Zhongli's hands grasp the falsely frail-looking wrists and hold on as he grinds again, making Xiao shake and wriggle like one abused nerve under Zhongli's gaze. He hopes, come what may, he will never lose memories of Xiao right there, open and gasping for him. Only remembering, reliving, moments like these with Xiao, Xiao's rare smiles, his scent, habits and piercing eyes, would be the kind of form of immortality Zhongli would happily accept for himself.
Zhongli brushes his mouth against Xiao's ear and nibbles the red skin of it before he says, "Give it all to me then, dearest. I will take it."
Xiao's thighs squeeze him. "Can't- I-"
Zhongli smiles at the tremble of Xiao's voice, his shivers and moans preventing him from speaking more than two words. Zhongli knows he's oversensitive, this very angle is so sweet for both of them and Xiao is beside himself at the constant pressure Zhongli is putting on it, his grinding only adding more and more pleasure, a pile that will crumble only when Zhongli allows so.
"Yes, you can. Come. Just like this."
Xiao gasps heavily, his mouth uncapable of closing itself.
"Zhong- AH-"
Zhongli squeezes his wrists harder, presses his forehead against the soft sheet beside Xiao's sweaty hair and groans at the feeling when he finally lets himself pull out, slam back in with a force that makes his glowing arms tingle. Xiao lets out a choking sound and then moans, almost mewls when Zhongli picks up speed, hitting that same spot over and over again.
Ah. It's always like this, a silent give and give before ultimately one of them has to take, take and take. Zhongli admires Xiao's stamina and control, the sounds he lets out in the space between them are the most precious and Zhongli breathes for them as much as he breathes for the way Xiao squeezes him, looks at him, loves him.
Xiao asked Zhongli to just take this time but Zhongli believes he can take only when Xiao does the same for him. Take the pleasure and attention Zhongli gives him, crumble and scream before Zhongli too loses himself and falls over the edge.
He releases Xiao's wrists and shifts his weight on his knees only, so he can wrap his fingers around Xiao's small waist. Xiao groans at the movement and Zhongli's touch on his hips, frustration clear in his eyes and his red, neglected cock. It looks good enough to eat just as the rest of Xiao, but Zhongli will give attention to it later. Right now he focuses on gripping the pale hips and pulling them towards himself, moving Xiao's body as he likes, to lovingly abuse Xiao's sweet spot.
Xiao would normally be vexed about Zhongli doing everything but tonight he's pliant and open in Zhongli's hands, and his moans get louder when Zhongli moves both his own hips and Xiao's in a fast rhythm, the obscene sounds of their flesh and Zhongli's own groans joining in with Xiao's noises of pleasure.
Xiao is squeezing the sheets between his fingers, his calves linked behind Zhongli's lower back in a death grip and his mouth glistens with sweat and spit. Zhongli wants to kiss him, devour him.
"Xiao," Zhongli says, adrubtly changing their pace to slow once again.
Xiao almost whines at the change and opens his eyes as an answer to Zhongli's call.
"Put your hands around me, little bird," Zhongli barely manages to say before grunting at Xiao squeezing his muscles around him. He then eyes at the sheet between Xiao's fingers. "I want all of you on me."
Xiao doesn't need any aid in bending his body up and forward, and his arms are then around Zhongli's neck and shoulders like they belong there.
Zhongli lets out a pleased hum and presses his nose against Xiao's. Xiao looks only a bit embarrassed, and Zhongli can see a beginning of a smile in the corners of his mouth. But that ghost of a smile disappears and Xiao kisses him hard, firmly taking a seat in Zhongli's lap and shifts, grinds only a bit. They both groan into each others mouth and open their eyes at the sound, then stare at each other for a moment that feels too fleeting and yet prolonged at the same time. Zhongli strokes the skin of the yaksha's hips briefly and then pulls him up, then back down on his cock. Xiao's eyes flutter but he keeps his gaze on Zhongli, his eyes roaming around his face but always coming back to his eyes as Zhongli moves his body on his cock. When the pace picks up once more, Xiao can't seem to stop his eyes from closing at the sensation anymore. Zhongli knows how he must feel, yet he stubbornly tries to keep his own eyes open to look at Xiao's face twisted in pleasure, his mouth and eyelashes trembling, blush spreading from his face to throat and collarbones.
When Xiao comes, Zhongli has admitted defeat and buried his face into the yaksha's neck and roughly kissing the skin there. One slow but deep push inside after unknown amount of time of pounding in quick and ruthless pace makes Xiao crumble and Zhongli feels his cum cover his stomach. It doesn't take more than few thrusts for him to loudly groan into Xiao's skin and come too, shivering in Xiao's equally trembling embrace.
Take and take.
Xiao's fingers slide through his hair with familiar rhythm. Zhongli lets himself squeeze Xiao in his embrace, this moment of peace allowing him to follow his desire to not let go of the Yaksha, only tighten his grip. Xiao exhales shakily, yhe melody of joy in his breath; a chuckle almost.
Give and give.
