Wei Wuxian's body jolts with each thrust of his husband's huge cock inside of him. Lan Wangji had cleared their dishes from dinner and then proceeded to bend Wei Wuxian over the low table, pressing his chest into the wood with a large, solid palm to the center of his back.
Wei Wuxian's wrists are bound behind his back with his husband's forehead ribbon, so he has no leverage to control the way his body jerks against the table. The most he can do is turn his head to the side and endure.
His husband's stamina is, as always, impressive and little frightening. He's already come inside Wei Wuxian once, but his cock remained hard and he had barely paused in his rhythm, just fucking right on, his own spend providing extra lubrication.
Sadly, this feat is so commonplace it doesn't even bear remarking on. Wei Wuxian is more surprised when his husband takes a break after his first orgasm. He's well accustomed to Lan Wangji using his body as he pleases, treating Wei Wuxian like nothing more than a warm hole to fuck his cock into until he's satisfied.
Lan Wangji is very, very hard to satisfy.
He's not always in such a hurry to get started, though. Tonight, he hadn't dragged Wei Wuxian whining and protesting over to the bed before having his way with him. He hadn't even bothered to undress him beyond the bare minimum needed to get at his hole. He'd pushed Wei Wuxian's robes out of the way, bunching them up around his waist, and tugged his trousers down to mid-thigh.
There's no need to prep Wei Wuxian's body anymore. His hole stays obediently loose and wet for his husbands pleasure at all times, never given a chance to do otherwise with how often Lan Wangji makes use of it.
As always, Wei Wuxian is noisy while his husband fucks him. A lot of it is wordless grunts and moans and cries and screams, the sounds pushed out of him by the powerful thrusts of that massive pillar inside him. But in between he talks, chatters away. If Lan Wangji wants him to shut up, he'll put a hand over his mouth or gag him. Otherwise Wei Wuxian will just keep talking.
"Oh, Hanguang jun," he moans. "So cruel to your poor wife! My delicate body can't take such rough treatment. Go softer, er-gege!"
Lan Wangji does not. Wei Wuxian's painfully hard and neglected cock twitches.
"Everybody thinks their esteemed Chief Cultivator is sooo noble and pure! If only they knew how you rape your your little wife every night for hours!"
Lan Wangji's hands tighten around Wei Wuxian's hips, digging in hard enough they're sure to leave bruises, and gives a few long, particularly brutal thrusts, somehow entering even deeper into Wei Wuxian's body spread out beneath him.
"Oh, fuck!" Tears spring to Wei Wuxian's eyes at the increased force, teasing forgotten. His hands spasm where they're bound at the small of his back, curling into fists and releasing uselessly. "Ah, ah, ah!" His voice rises on an uneven wail as his body is pushed to its limit. "H—husband, have mercy! It's too deep. I can't—I cant! Oh gods, oh fuck, touch me, touch me, touch me! Pleeeaaase!"
Lan Wangji does not release his bruising grip on Wei Wuxian's hips, continuing to fuck deep inside him.
Wei Wuxian is trying to struggle now, but there's very little he can do in this position. His voice is gone a bit hoarse from screaming, and his breathing is labored. He's sobbing on every exhale.
And then, Lan Wangji hits the angle inside him just right, and Wei Wuxian is coming hard enough he blacks out for a few seconds, come spattering all over the floor.
The orgasm makes his muscles clench around Lan Wangji's cock, and his husband shoots a second load of come into his abused hole.
When Wei Wuxian comes back to himself, his husband is still fucking him, cock as hard as ever even after two orgasms. This is slightly more unusual. Most nights, Lan Wangji will take a short break after he comes a second time.
Wei Wuxian groans, low and pained, his voice soft and fucked out now. "Oh, er-gege, why is your cock so insatiable? Your wife's poor body can't take any more. Won't you take pity and rest a bit?" He even means it a little bit this time. His neck is twinging from having his head twisted to the side for so long, and his hips are starting to cramp up from being held in the same position, spread out over the table for so long. He starts grasping at straws.
"Husband, let's take a little break now, okay?"
Lan Wangji does not pause in shoving his cock into Wei Ying's hole.
"You—you drank so much tea at dinner!" he exclaims, seizing on an idea. "Surely by now you must need to—to take care of that, right? Why don't you just go to the bathroom real quick. I'll wait right here, promise!"
"Hm," Lan Wangji says, speaking for the first time in a while. After another few moments (and thrusts) he adds, "No need."
"What no need? Everybody has to piss, even the great Hanguang jun!"
"Wei Ying is here," Lan Wangji answers incongruously. Finally, finally his thrusts slow and gentle a bit, giving Wei Wuxian a much needed respite. After a moment, his hips even still entirely, buried to the hilt in Wei Wuxian's ass.
And then. Wei Wuxian feels something hot and wet inside, a very different sensation than being filled with come. Within seconds, warm liquid starts to leak from his hole, a continuous stream as Lan Wangji keeps—"Oh!" Wei Ying cries out, when he figures out what's happening.
Lan Wangji is pissing inside Wei Wuxian's ass. The hot, salty liquid splashes against his inner walls, filling his hole and overflowing, gushing out around Lan Wangji's cock. It's dripping down Wei Wuxian's thighs and over his balls, and leaking onto the floor.
It's filthy. It's degrading. Even more so than being used as Lan Wangji's fuck toy. Now he's being used as his husband's toilet. He's just a thing to be debased and used. It's humiliating. Wei Wuxian's whole face has gone hot and red, and tears leak out from where he has his eyes screwed shut against the shame. His cock, despite coming so recently, starts to get hard again, even as it's drenched in warm piss.
It seems to take a long time for Lan Wangji to empty his bladder into Wei Wuxian's waiting receptacle. But at last the stream slows to a trickle. And Wei Wuxian realizes his husband is still hard, even after all that. He starts thrusting again, shallowly at first. And every time his cock slides inside, it pushes a little more piss out of Wei Wuxian's hole.
If Wei Wuxian thought the sounds of their coupling were obscene before, it's even worse (better) now. The wet squelching and slapping of skin on skin, as Lan Wangji smears Wei Wuxian's insides with his piss and come, marking him up and claiming him like some animal. The feral possessiveness makes Wei Wuxian a little light headed with the way all his blood rushes to his cock so fast.
He's finally beyond words, reduced to just taking what his husband gives him. Tears roll down his face, and he whimpers and sobs from overstimulation, his nerves raw and shocky after being fucked for so long, combined with the intoxicating swirl of arousal and humiliation. The dirty bad wrong hot good sweeping through his body like a tide. It pulls him under, to a place where there are no thoughts, no self, just the simple fact of being used until his husband says enough.
As Lan Wangji gets close to the edge again, he lands a few stinging slaps on Wei Wuxian's ass. Not a punishment, just another small claiming of what is his. And his husband likes the pain. Each smack sends a zinging little shiver of pleasurepain through his body, even as his mind is too gone to really register it. His cock stiffens to an almost painful degree, and his balls draw up, hovering on the edge of orgasm.
After a few more punishing thrusts, Lan Wangji comes a third time, spilling even more milky white fluid into Wei Wuxian's already sopping and ruined hole. At the same moment, he slaps Wei Wuxian's ass again. Hard. And his husband comes untouched for a second time body jerking and trembling all over, Wei Wuxian too checked out to even be aware of his movements.
Wei Wuxian is floating on a haze of endorphins, mind still mostly checked out. He registers vague impressions of being untied, his wrists massaged where they've been bound for so long. Of being stripped out of his soiled clothes. A big hand brushing his hair back from his face. Soft words of praise, and chaste kisses to his forehead, his cheek, his shoulder. Being picked up and cradled against a broad, muscular chest.
The next time Wei Wuxian is fully cognizant, Lan Wangji is lowering him into a steaming bath before climbing in behind him. He hums in deep contentment. "Er-gege, so dirty," he purrs, tipping his head back against his husband's shoulder.
"Mn."
"I can hear you smirking, you know. No need to be so smug about it. Wei Ying loves everything his Lan Zhan does to him, even when it's filthy." A pause. "Especially when it's filthy." A lazy grin stretches across his face. His body feels so good, wrung out and exhausted, worked over in the best possible way. He arches back against Lan Wangji, feeling the sweet ache in his muscles.
Eyes still closed, he angles his head up, a wordless request. Lan Wangji indulges him immediately, capturing his lips in a slow, deep kiss. Wei Wuxian sighs into it, completely sated.
Later, when they're wrapped around each other in bed, Wei Wuxian grins mischievously in the dark. "Er-gege," he whispers.
"Mm?"
"Tomorrow, you should hold it all day, okay? Wait until you come home, and then fill up your wife's needy hole with your piss. Save it all for me, yeah?"
Lan Wangji growls and bites his ear softly. "Mark your words," he says.
Wei Wuxian shivers in anticipation and burrows deeper into his husband's arms. He can't wait.
