Chapter Text
The lewd slurp echoed loudly throughout the office as Jiang Xi pressed his hand to the head between his legs with a low groan. It was barely audible, but the tremors shot down through his body, ending in a vibration shooting through his dick. The person whose mouth encompassed his length hummed, their tongue pressing into a throbbing vein before they dragged it upwards and over his leaking slit.
Jiang Xi hissed and tugged on the hair in his hand, roughly pulling it back so that he could glare down into the flushed face and swollen lips of the one attending to his arousal. “What did I say about teeth?”
“To be careful of them…” Xue Meng murmured, his eyes heavy with lust. “Sorry, daddy.” Jiang Xi rolled his eyes and pushed his son’s head back down onto his lap. This was his birth son–he hadn’t raised him though. In fact, he’d barely even gotten attached to him in any way; or at least that was the excuse he told himself as his son continued to service him. Xue Meng took him down his throat, his fingers wrapping around the base of his cock to jerk him into his mouth and Jiang Xi groaned with pleasure at the feeling.
He stroked his thumb along the side of Xue Meng’s jaw and let his eyes fall shut as he leaned back into his office chair. The first time his son had taken his cock down his throat, it had been sloppy and not at all good. Afterwards, Jiang Xi had sat there wondered if the bad blowjob had been his punishment for getting physical with his actual birth son in the first place because, truly, what the fuck was he even doing?
Inside, Jiang Xi knew that this was totally wrong, abhorrent, completely and utterly disgusting. He really, honestly deserved to be locked in jail for willingly putting his cock, the thing that helped birth this creature between his legs, into his own son’s mouth. But the knowledge of it alone wasn't enough to get him to stop. If anything, it made him harder.
That was probably the most fucked up bit.
He gripped Xue Meng’s hair, grunting as he felt another drag of teeth across his length and pulled him up, grasping him tightly by the chin. “Kid, you keep doing it.”
Xue Meng flushed, his eyes so similar to Jiang Xi’s own as they narrowed into a glare. The effect was lost by the pink flush and saliva dripping down his chin however and Jiang Xi felt his lip give a small twitch upwards. “It’s your fault for having such a–” Xue Meng snapped his mouth shut and looked off to the side, seeming to realize that what he was about to say wouldn’t actually be something insulting.
“Hm,” Jiang Xi smirked smugly and then pulled his son up beneath his arms, pushing him onto his desk. “Fine, then let’s do something different.”
“D-different?” Xue Meng suddenly stuttered, his hands clutching at the desk beneath him. “Like?” Jiang Xi merely tossed him a look before pulling open a drawer from his desk. From it, he grabbed a full bottle of medical grade lubricant as well as a pair of blue latex gloves.
“Xue Meng,” Jiang Xi began, pulling the gloves over his hands, letting the latex snap against his wrist almost threateningly as he glanced down at his kid. “Do you realize how important it is to have your prostate examined?”
The next thing either of them knew, Xue Meng was roughly turned around and bent over the desk with his pants and underwear down around his ankles. Everything that had been on the desk had been pushed off and Jiang Xi worked the lube over his gloved hands. Tossing the bottle aside after making sure there was plenty, he pulled Xue Meng’s cheeks apart and gently prodded at the tight, pink hole.
Xue Meng jerked, hissing as he tried to move away from the prodding but Jiang Xi firmly held him down. “That’s cold!” He whined, grasping tightly at the opposite end of the desk.
Jiang Xi fought from rolling his eyes again, but it was difficult to do whenever Xue Meng opened his mouth. The kid might be his and he might actually be smart, but he was truly an idiot .
“Stop being a baby,” Jiang Xi told his son, pressing a lubricated, gloved digit into the waiting entrance. Xue Meng let out a slight whine, but otherwise stayed silent as the older man trailed his fingers along his insides. He knew right where the prostate should be located, but he took his time, watching as his child’s body slowly turned redder with each passing second.
Xue Meng hid his head in his arms and Jiang Xi gave a small chuckle, pressing in a second finger before spreading them, stretching him out. “You’re tense,” Jiang Xi noted, comfortingly rubbing the small of Xue Meng’s back. “You need to relax.”
“Y-You try to relax with your dad’s fingers up your ass and we’ll see how you do!” Xue Meng gasped out, his thighs clenching around the corner of the desk where he was situated.
“You just had your dad’s cock in your mouth a moment ago, don’t you remember?” Jiang Xi couldn’t help but tease, shoving his fingers deeper inside the other.
Xue Meng whimpered and lifted his head, tossing him a pretty glare over his shoulder. “Sh-shut up you old perv–AH!” His sentence broke off into a cry as Jiang Xi finally “found” his prostate, thrusting his fingers as hard as he could into the pleasure point. It left Xue Meng quiet, but panting, which Jiang Xi much preferred.
“It seems fairly healthy to me.” Jiang Xi mused, prodding at it again as he watched his son become a writhing mess on his desk. He just knew that by the time he pulled the young man up, his desk would be covered in a slick white sheen of Xue Meng’s cum.
“Wh-why do you have to play doctor? C-can’t you just fuck me like a normal pervy old guy?” Xue Meng whined out, his hands clenched into fists.
Jiang Xi snorted and pulled his fingers out of his son’s ass. Quickly, he rid himself of the gloves, tossing them into the trash can on the side of his desk. “You sure are eager for this pervy old guy to fuck you –especially considering who I am to you.”
Xue Meng flushed and opened his mouth to deny it, but seemed to remember the distinct image of himself calling Jiang Xi “daddy” just moments prior and firmly snapped his mouth shut. Jiang Xi grabbed the lube, shoving his pants down around his thighs and freeing his own throbbing cock.
As much as he hated himself for it, there was something deeply arousing about pressing the leaking tip of his thick cock against his son’s tight hole. Xue Meng mewled at the feel of it, rubbing his hips backwards and spreading his legs even further.
“You like this, don’t you?” Jiang Xi stated, one hand on the base of his cock while the other softly stroked his son’s hair. “Being full of your birth father’s cock, having his cum spilling into your stomach. Those are your unborn brothers and sisters you know.”
Xue Meng’s entire body shuddered and turned a deep pink all at once. He sputtered, his nails digging into the desk beneath him. “Wh-what the fuck?! You’re so fucking gross–just put it in already and shut the hell up, oh my god…”
Jiang Xi smirked and then began pressing himself into the tight body waiting for him. He groaned beneath his breath, holding himself steady as Xue Meng’s body clenched around him. “Shh… relax Xue Meng, or this is going to be more uncomfortable than it needs to be.”
“I know that!” Xue Meng snapped and then let out a whimper. Jiang Xi reached down beneath his son and wrapped his fingers around his cock, gently stroking his length.
Slowly, Xue Meng began to relax, his body opening up to his birth father’s cock as it continued pressing in, until Jiang Xi felt himself bottom out–he could go no further. He let out a small, relieved sigh, and softly patted his son’s hip. “Good boy,”
He felt Xue Meng shudder beneath him and pressed a kiss down against his shoulder, breathing into his ear. “Stay relaxed, Meng. Your daddy’s got you.” Jiang Xi promised lightly, watching as Xue Meng turned his head just slightly. Xue Meng’s eyes shook in nervous anticipation but then he nodded, giving Jiang Xi the go-ahead he needed.
Jiang Xi licked over his lips and inhaled deeply as he clutched his son’s waist with one hand and pulled himself from the tight body, leaving only the head in. He moaned as the pink hole tightened its hold around his swollen tip and then pushed back in, his length sliding through the clenching tunnel.
“Fuck…” he cursed, wondering if he had ever been in something as tight before. He couldn’t remember, but then again, he had never spent much of his life beholden to past affairs–not that there had been many of them that he actually cared about.
Xue Meng was something different. He wasn’t just a quick fuck–Xue Meng was a product of his own flesh and blood. Jiang Xi had made him–even if he hadn’t known that for practically Xue Meng’s entire life. He could now see the similarities between them though, and deep inside he despised himself for what he was doing, ruining a good thing he had actually made in this way.
He was literally taking Xue Meng and sullying him.
Jiang Xi slammed harder into the boy beneath him, a cry breaking out from Xue Meng’s mouth as he gasped, his hips pushing backwards to meet Jiang Xi’s thrust. “D-daddy…” Xue Meng whimpered and the fire coiling in Jiang Xi’s stomach quickly burst.
He grasped the boy’s hips, driving faster and deeper into him, his entire body shaking as he fucked his son down into the desk. Xue Meng cried out, arching himself back, his hands slamming down into the wood as he clenched desperately around him. The pounding of his fists and the lewd sounds of Jiang Xi fucking into him grew louder until finally–
Jiang Xi snapped awake, his entire body tensing from whatever loud noise had awoken him. His neck ached from the position he’d fallen asleep in at his desk, but something else ached as well. He glanced down at his lap to see his cock straining beneath his clothes and groaned heavily.
Had he just had another one of those dreams? Really? And about his son at that? He was truly going to hell…
He rubbed his hands across his face, the images from his dream flashing through his mind. Xue Meng sucking his cock, his fingers in Xue Meng’s ass, his cock in Xue Meng’s ass, Xue Meng calling him “daddy” in a not-so-innocent way.
His stomach stirred as he thought about it and Jiang Xi cursed himself for being so disgusting.
A knock sounded at his door and Jiang Xi looked up quickly. Had that been what had awoken him from his sleep? Whoever it was, he surely had to thank for pulling him from that disturbing nightmare–
“Are you going to open up?! I’ve been out here for five minutes banging on the door!” Xue Meng. Shit.
With a groan, Jiang Xi reached down and tried to adjust himself before pulling himself from his desk. Inwardly, he wondered what sort of luck he had. Of course it was his son who had woken him up from a dream about fucking him. Of course it was.
Jiang Xi pulled the door open with a glare down at the little brat who barely even shot him a glance before sauntering in like he owned the place, a small nondescript bag held in his hand. Xue Meng truly was like a peacock.
“Who the fuck locks the door to their office in their own house while they’re inside it?” Xue Meng asked, plopping himself down in one of the leather chairs in front of Jiang Xi’s desk.
Jiang Xi pushed the door closed, trying so hard not to roll his eyes he felt as if they were about to pop out of his skull. “The kind who has a brat kid with a key for emergencies only , but takes it upon themselves to waltz right into a house that isn’t theirs whenever they like.” Truthfully, Jiang Xi didn’t mind Xue Meng dropping by whenever he wanted, but even with a gun pointed at his head, he would never admit that.
“Whatever,” Xue Meng scoffed and Jiang Xi sighed as he lowered himself back into his chair. He tried not to look directly at Xue Meng and instead focused on the papers and files on his desk, trying to get them in order under the guise of them being confidential patient information.
Truthfully, he was just terrified that if he looked at his son, he’d bend the boy over his desk and spank him for his impudence before he could stop himself.
“What are you doing here?” He asked and when Xue Meng didn’t answer right away, Jiang Xi finally worked up the courage to look up, his son seemed to be looking everywhere but at him as his face flushed pink in embarrassment.
He mumbled something and Jiang Xi twitched in annoyance. “If you’re going to say something, say it clearly. I can’t hear you.”
“Maybe you’re just getting old and your hearing is going bad.” Jiang Xi stared and Xue Meng huffed, crossing his arms over his chest. “It’s Father’s Day so… mom made me get you a Father’s Day present.”
Jiang Xi glanced at the small bag and then thought back to the dream he had. He cleared his throat and leaned back into his chair. “A Father’s Day present.” He repeated, his brain whirling.
“That’s what I said.” Xue Meng rolled his eyes and then pushed the bag forward. “Here. It’s really nothing special.”
A part of Jiang Xi wanted to not open it, at least not until Xue Meng left, but instead he found his hands reaching for the bag, noting that it was something hard and likely fragile to the touch. Carefully, he unwrapped it, tossing the paper in the trash.
He stared down at the present, unsure about whether or not he should be happy or insulted.
“World’s Best #2 Dad…” he said slowly, reading the sparkling blue letters on the white coffee mug.
“Yeah, well, you’re not #1 because that belongs to my actual dad.” Xue Meng said, raising his brows as if daring Jiang Xi to argue over it. But he wouldn’t. It was true anyway. How could he be a good dad if not only had he not known that he’d had a son for twenty-some years, but also that every night he fell asleep to the thought of his face between Xue Meng’s thighs, his tongue delving into that spot which should be forbidden to him?
“At least it’s useful.” Jiang Xi stated, pushing it to the side before picking up his pen to go back to his papers.
“It’s a good gift.” Xue Meng stated and then fell silent. “I guess I should go then, let you get back to that. I just had to come give that to you, ‘cuz, you know, mom made me. I honestly just picked it up at the mall on the way here, it’s really nothing special.”
Jiang Xi hummed and didn’t say anything, not even glancing up when he heard a sigh as Xue Meng started walking back towards the door. His fingers clenched around his pen and he looked up, turning to look at his son.
“Xue Meng,” he called out, his son pausing to look back around at him. “Are you still needing help with your science?” Xue Meng blinked and then gave a slow nod. Jiang Xi eyed him and then turned back to look at the files littering his desk. “Thursday night. I’m off. I’ll help you with it.”
There was a beat, and then, “Thanks. I’ll uh–I’ll be by in the evening.” And then Xue Meng walked out, closing the door behind him.
Jiang Xi let out a slow breath, his entire body relaxing though he hadn’t realized how tense he had been. This wasn’t normal, not at all, but it had become normal for him.
He looked towards the World’s Best #2 Dad mug, tapping his pen against the paper. Jiang Xi then dropped the pen and grabbed the mug, pushing himself up from his desk.
He could go for some coffee.
