Xiao Zai knew he was risking a lot by saying something like that, but his blood still sang in anticipation in the split second it took Chu Yun to react.
At first, his exquisite features went slack with shock, and then tight with anger. The sharp sting of a slap struck Xiao Zai across the cheek.
"How dare you?" Chu Yun hissed, his teeth bared.
Xiao Zai sucked on a ragged breath, snapping his hips into Chu Yun with abandon. Despite the outrage on his face, he'd gone tighter inside, wrapping around Xiao Zai like a tight fitting glove.
"Slap me again if you're so angry." Xiao Zai grinned, hoping he would.
Chu Yun did. Harder than before even.
Xiao Zai hissed through his teeth and fucked into him harder. Watching in delight as Chu Yun's eyes rolled back into his skull when his cock brushed against the spot inside him that made his inner muscles go tight like a warm, clenching fist. Xiao Zai kept aiming for that spot, keeping a steady pace and fucking increasingly more erotic sounds out of Chu Yun slack mouth.
He took it as a personal challenge to unravel Chu Yun's tightly held control, and make him give into his lust, his desire. He was breathtaking in the throes of ecstasy. All the muscles in his body straining with tension, working to stave off an inevitable orgasm. His skin shone with perspiration, inviting Xiao Zai to lick it. He laved Chu Yun's right nipple, rubbing his thumb across the the left, still faintly wet with traces of saliva.
Chu Yun pushed his chest against Xiao Zai's face, and his ass into his thrusts, with a bitten off moan.
If Xiao Zai said all the filth running through his mind he'd end up much worse than with a couple of slaps. Most of it was mindless, base stuff, like how Chu Yun's tight, scorching hole felt like it was made for Xiao Zai to fuck, how the breadth of his wide shoulders highlighted the slender dip of his narrow waist, how his long legs made Xiao Zai want to cover them in bites.
But what would really make Chu Yun furious with him were all the sentimental admissions. Like how they were made for each other, how it was fate that had brought them together, how Xiao Zai would trade ten years of his life to spend a single one at Chu Yun's side.
Xiao Zai kept suckling at Chu Yun's nipple, rolling the tight peak around with his tongue while thinking of everything he still wanted to do to Chu Yun, still wanted to tell him.
A sharp sting on his scalp reminded him that Chu Yun's temper was as volatile as the weather. "That's enough, you're sucking it raw." He pulled Xiao Zai's head off his chest by the coil of hair wrapped around his fist, his words mellowed by the panting of his breath.
"You think you'll have milk?" Xiao Zai said, unable to stop that particular thought as he had been all the others.
He got another slap, and Chu Yun's blunt nails scored down his back for his troubles. "Are you an animal?" he snarled, even as his legs tightened around Xiao Zai's hips, and he continued meeting him thrust for thrust.
Chu Yun's body said one thing and his mouth another. It was maddening, but Xiao Zai wouldn't have him any other way. Contrarian bastard that he was, spoilt vixen, demanding tease, calamitous beauty, arrogant strategist -- Xiao Zai wanted all of him.
"I'm your animal," Xiao Zai said with a harsh snap of his hips, drinking in the sight of Chu Yun's mouth falling open on a moan and his eyebrows knitting together in overwhelmed pleasure.
He could feel the effect of his words on Chu Yun, his tight channel squeezing around his cock so tightly it made Xiao Zai have to slow down the rhythm of his thrusts. He was close, he could feel the tell-tale throb at the base of his cock.
Xiao Zai wanted to mark Chu Yun so much that it made his breath catch, but he wanted Chu Yun to ask him for it, beg him even. So instead he forced himself to lower his head into the crook of his neck and lick the skin teasingly, leaving a placeholder, until the day came.
"You're mine too," he whispered against Chu Yun's ear, cupping the back of his neck "you're my animal too, my alpha, my husband, my Yun-er," he punctuated each word with a snap of his hips, dragging keening sounds out of Chu Yun's raw throat, bringing them both closer and closer to the precipice.
Tears of desire were gathering at the reddened corners of Chu Yun's eyes, a sight so incredibly erotic it nearly undid Xiao Zai.
"All of me belongs to you, and all of you belongs to me," he hissed, his rut taking him to frenzied heights. "One day I'm going to unhinge my jaw and swallow you whole."
Chu Yun shouted as orgasm stole through his body with the violence of thunder. His red cock shot ropes of white cum up his chest, into his own panting mouth. He came only from the cock fucking him, like Xiao Zai said he'd make him.
That thought alone, and the vicious clenching of his hole was enough to bring Xiao Zai over the edge. Knot sliding easily inside despite the contractions of Chu Yun's channel.
Chu Yun wrapped his arms around Xiao Zai's neck and crushed their lips together in a vicious kiss. Not giving into softness even after his body was sated. It was up to Xiao Zai to gentle him with tiny sipping kisses, with slow rocks of his hips as he filled him up.
Slowly, after Chu Yun had calmed down enough for it, Xiao Zai turned them on their sides, so they could wait out his knot in a more comfortable position. He dropped kisses onto Chu Yun's unblemished nape, imagining how it would look with his mark.
He banded an arm around Chu Yun's waist, his palm pressed tightly against his abdomen. Chu Yun slid his own hand over Xiao Zai's arm, but instead of batting it away, like he expected him to, he laced their fingers together.. With a sigh he settled back into Xiao Zai's embrace, his tired breath brushing against Xiao Zai's bicep in warm, sleepy puffs.
