“Iiiiiiit’s Ten-Tennnn!”
Kun dropped his face into his palms. “For the love of god, Ten, I don’t need this right now.”
“You seem…stressed,” the other purred, leaning down over the back of the desk chair to brush his lips against Kun’s ear. Kun shivered involuntarily and tried to ignore the familiar scent of gardenia that washed over him.
Swatting Ten away as if he were a mosquito, Kun repeated, “No, not now. The anatomy-physiology exam is in approximately…” he lifted his empty wrist, then flung his arm to the side in disgust. “Approximately in fifty-two hours.”
Ten straightened his shoulders. “Would you care for some advice?”
Kun side-eyed him warily. “Your advice is never good.”
“Well you haven’t even heard it yet.”
“Fine, go.”
“I propose,” Ten leaned closer. “That you,” he jabbed two fingers into Kun’s broad chest. “Go–out–tonight,” he punctuated each word by walking his fingertips upwards. “With me and the boys.” He tilted Kun’s chin up, which really meant Kun was looking at the ceiling. “And get wasted!” Ten flung his arms out, almost upending one of Kun’s beloved houseplants.
“You fucker,” Kun shoved his boyfriend out of the way, then threw himself back into his chair with a beleaguered sigh. “The only place I’d like to go tonight is the cadaver lab, which, unfortunately, is closed on the weekends.”
Ten scrunched his nose. “Gross. Why not study on a live body?”
“Because–” Kun began, as Ten started to rearrange himself on the bed in a spreadeagle position. “Excuse you.”
“Doctor, please, I need a physical exam,” Ten batted his eyes, looking up at Kun with a devilish grin.
Kun flushed, but his eyes narrowed. “I fail to see how this will help me study. What do you know?”
“Okay firstly, rude. How do you think I managed to get into art school? Secondly, I know a little about human anatomy.” He waggled his eyebrows lasciviously, then flopped back down with a reminiscent little huff. “It all started in Professor Kwon’s Figure Drawing II course…”
As tempting as the offer was, there was really nothing like the cadaver model, plus, Kun didn’t see how this would help him cram weeks of firehose-level information into two days. He worried his lower lip between his teeth, chewing it anxiously until Ten had to reach out and release the skin with soft fingers.
“Hey, baby, you’re going to be fine. Think of all the exams you’ve studied for and passed so far! This will be no different.”
“No two bodies are the same. There’s no guarantee you’ll be similar to the cadaver model,” Kun waffled.
Ten snorted in distaste. “Honey, if anything, I’m better than the cadaver. I’m a perfect human specimen, you know.”
“I mean, I agree, but–”
“Okay, what section are we doing first?” Ten had stripped his t-shirt and now lay on the bed in a supine position, a tangible, half-naked anatomy textbook drawing. The ink on his chest and arms rippled as he nestled into the mattress, getting comfortable.
“I was in the middle of the digestive system, I guess.”
“Go for it. My mouth is here.” Ten demonstrated by waggling his tongue salaciously.
Kun’s eyes flicked towards him, but he carried on nobly. “Yes, digestion does start in the mouth. Then, food travels down the esophagus towards the esophageal sphincter before reaching the stomach.” He pointed towards Ten’s throat, then over his sternum.
“The small intestine is split into three parts.” Kun smoothed his palm over Ten’s flat belly as his brain kicked into gear. “Duodenum. Jejunum. Ileum. This is where your cells break the food up into microscopic parts, absorbs the nutrients you need, and dumps the waste, which then makes its way into the large intestine and out of the body.” He traced a finger in a counterclockwise square shape across Ten’s torso, then drew an invisible vertical line over the skin between his hip bones. Ten’s breath hitched. Kun leaned past him to scroll over his iPad notes.
They moved to the circulatory system next. Kun taught Ten which direction the blood flowed, both oxygenated and deoxygenated blood, from body to heart to lungs, from lungs to heart to body. He pressed his ear against his chest to follow his heartbeat, the steady ba-thump of each contraction. He traced snail trails across Ten’s pectorals and the dark ink there, fingertips splaying in feather-light touches to show where the aortic arches ascended just below his left collarbone.
Ten wasn’t sure if his boyfriend truly didn’t notice the way his nipples peaked when he dragged his calloused fingertips across them, or if he couldn’t hear the way he was trying to keep his breath slow and even, or if Kun was simply choosing to ignore him out of the necessity of cramming. If Kun noticed how Ten’s heartbeat had sped up beneath his palms, he said nothing, his handsome face chiseled into the perfect depiction of intense focus. For someone who claimed to “know nothing” of the material, every portion of Ten’s body had been mapped out confidently with barely a glance at the notes.
Ten grabbed the textbook and flipped through it until he found what he wanted, jabbing a manicured finger against the page. “Do this next.”
“Reproductive system? We only just reviewed that section.”
“Will it be on the exam?” It came out more demanding than Ten had intended.
“Well, yeah.”
“Then get to it, Doctor Qian.”
Kun’s eyes flashed with something like ambition, which hardened into resolve as he began to locate the correct notes on his iPad. Ten ever-so-subtly shimmied the waistband of his sweatpants as low as he could.
“The reproductive system is pretty straightforward,” Kun said as he splayed his hands over Ten’s hips. “Females have a uterus and ovaries, here,” he traced a T-shape. “And males, well, have external bits.” He gestured vaguely to Ten’s crotch, as if nervous about what was underneath the soft fabric.
“Go on,” Ten purred. He took Kun’s hesitation as a sign that he needed some encouragement, so Ten shucked off his bottoms in one go, finally fully naked. He searched Kun’s face for some sign of acknowledgement of his incredible figure, but Kun, to Ten’s dismay, continued to be nothing but professional as he dutifully pointed out body parts. Ilium, ischium, sacrum. Genitofemoral nerve, inguinal ligament, internal oblique muscles. Scrotum, testes, penis. It was becoming the world’s most boring, and least sexy, game of “I Spy”.
This would simply not do.
As Kun was muttering the words “fallopian tube” and “luteal phase”, Ten decided that he’d had enough. He grabbed one of Kun’s hands and used it to cup his naked almost-erection. Kun let out a small noise of protest, Ten firmly dragged him downwards by his nape until their noses brushed.
“I would like to know,” Ten growled against Kun’s mouth, “what it would take, physiologically speaking, for me to cum.”
The light drained out of Kun’s eyes until he was staring at Ten with a level, loaded gaze. For a heartbeat, Ten was sure that he’d be rejected again. Who could come between a man and his studies? But Kun suddenly squeezed his palm experimentally and Ten squeaked in surprise and pleasure, feeling like a rabbit caught by a wolf. And he desperately wanted to be eaten.
“Well then,” Kun said darkly. “Why didn’t you just say so?” Without breaking eye contact, he slid his fingers over Ten’s perineum, fondling his balls and eliciting a light moan. Ten tried, and failed, to let a triumphant smile spread across his face as Kun continued speaking.
“Spermatogenesis–the production of sperm–starts in the testes.” Kun grazed his nails across Ten’s pubic bone, so close to where Ten wanted him most. “The sperm travel upward through several different ducts into another duct called the vas deferens. But sperm isn’t the only component in cum, you know. There’s nutrients and proteins and immune cells.” He leaned over to the side table to grab lube as he spoke. “And there’s a glycoprotein called mucin, which gives cum that distinct texture.”
“God, it’s so hot when you talk nerdy,” Ten moaned, extremely thrilled with how this was developing. Kun had barely touched him, yet his cock was almost fully hard, bobbing up as if it also liked the sound of those sciency-words. He gasped when a warm, wet finger met his entrance.
“These components come from several places,” Kun said, massaging Ten’s rim slowly. Ten’s breath hitched, and he willed his body to relax.
“The mucins come from Cowper’s gland.” He slipped one finger in, a relatively easy task. Ten whined.
“Some stuff comes from the epididymis and the seminal vesicles.” He pushed in a second finger. Ten breathed in and out, relishing the faint burn.
“And some of it,” Kun crooked his fingers upward, searching gently. “Comes from the prostate gland.” He pushed against a spongy nub of sensitive tissue, and Ten arched off the bed, keening high in his throat. Precum beaded at the head of his cock, and Kun didn’t miss a thing, using his free hand to collect it at the tip and rub it between his fingers as Ten watched with heavy-lidded eyes. “Precum is for clearing the way. And for lubrication.” He grinned devilishly, his eyes still predatory.
“Keep doing what you’re doing, and I can make more,” Ten huffed, arching his back to encourage more of Kun’s come-hither motions.
Kun tilted his head. “Can you now? Can you be that good?” He let Ten rut on his fingers for a few hot moments, then twisted his wrist, barely brushing that sensitive spot, and Ten squealed again, writhing against the sheets, his erection jerking pathetically, drooling precum in a little puddle over his soft belly.
Kun pressed a heavy palm against Ten’s sternum to pin him down. “Don’t come until I’ve fucked you,” he hummed. “We’re not done with the lesson.”
“Well get on with it,” Ten said breathily. He yelped as calloused fingers reached out to pinch the tender skin over his ribcage. He couldn’t stop being a brat, even if he tried. Sometimes he suspected that Kun lived for the Tom-and-Jerry, cat-and-mouse aspect of their relationship. After years of playing this familiar game, he knew Kun would always rise to the bait and would never pass up a chance to put him in his place.
What he didn’t expect was the sudden hot breath over his chest, a series of kitten licks across the ink there, a scrape of teeth, lips closing over a nipple and sucking hard as long fingers thrusted over and over into that bundle of nerves. Ten arched off the bed, eyes rolling back until he was positive he could see the amygdala in his brain, gasping as his pelvic muscles locked down in preparation, because a few more well-aimed strokes would get him there–
And then the fingers were gone. Ten lifted his head, chest heaving, about to scold his boyfriend to high heaven, but the words died in his throat as he watched Kun shuck off his remaining clothes and fist his own hard cock with generous lube. The lewd squelching sounds encouraged Ten to automatically open his legs, making space for Kun to settle between them.
“You okay?” Kun asked in a sudden moment of tenderness, mouth warm against Ten’s as the tip of his cock pressed against Ten’s entrance. Ten nodded vigorously, the desire in his belly pooling low and sweet and strong. He wound all his limbs around Kun’s body and tugged him close, transmitting all the affection he could through every inch of skin-to-skin contact.
They moaned in perfect unison as Kun pierced through and sank deep, burying his face into the crook of Ten’s neck, body wound tight like a notched arrow until Ten whispered, “Move, baobei .”
And so Kun did, bracing his forearms against the sheets as his hips flew forward, groaning into the curve of Ten’s shoulder as he fucked him.
“God, this is exactly what I wanted,” Ten moaned, threading his fingers into Kun’s soft hair, letting his boyfriend siphon all his pent-up energy and the stress of studying by railing Ten into oblivion. He could feel the familiar tightening of pleasure in his belly, felt his wet cock bob in anticipation of release. Just a little more, so close, if he just tugged on his own dick just a little, he could–
A iron hand flew onto his wrist, pinning it to the mattress, and Ten froze on instinct. “Ah-ah, not yet,” Kun scolded. He leaned so close that Ten could feel the scrape of his incisors over the vulnerable skin of his throat. “Get on your side, now.”
Ten let out a low wail of protest as Kun slid out, lamenting the loss of the tightness in his core. Even so, he dutifully rearranged himself, not-so-secretly admiring the way Kun’s lean arms rippled as he manhandled him into position. He could trust Kun. He knew he would take care of him.
They both moaned in harmony as Kun slid home again, grasping Ten’s narrow hips, suckling into the nape of his neck like a newborn kitten. The headboard creaked softly in a steady rhythm. Ten craned around to meet Kun’s eyes, still black as pitch. “By the way, did you get around to asking your professor why men have nipples?”
Kun snorted. “You’re bringing this up now?”
“Yes, because I want to tell you my theory.”
Kun grunted in reply and shifted slightly, hitting a particular spot just right, making Ten squeak. Ten laced his fingers through the hand on his hip and brought it to his pert nipples.
“They’re–” he sighed as Kun squeezed gently. “They’re only for pleasure.”
The vibrations of Kun’s hum traveled in shivers down Ten’s spine. “I like that theory.” Ten jerked in Kun’s grasp as he rolled a nipple between his thumb and forefinger. “And you, in particular, are very sensitive.” He angled his hips just right until Ten groaned, his back arching prettily, relishing the way those confident hands held him down so he could be fucked into, over and over.
All he could focus on was Kun’s hot breath over his spine, the relentless pace of his hips, the lewd squelching sounds of the lube over his ass, how he desperately wanted to rub his leaking erection into the sheets, but not willing to risk losing the sensation of Kun’s cock hitting that one perfect spot. He reached down to cup himself, but Kun beat him to it once again, jerking him off in quick, efficient strokes to the same rhythm of his thrusts, twisting his wrist, thumbing over the head.
Every muscle in Ten’s body was on fire, a relentless inferno bubbling inside him like the holy gates of hell. “More,” he whispered, the haze of lust clouding his vision. “C’mon baby.”
“Almost there,” Kun grunted, slamming into Ten’s lithe body, abandoning Ten’s dick in favor of gripping his hip in a way that was sure to leave bruises soon.
“Come inside,” Ten hissed, a hand flying over his cock as he chased his own high. “Come with me.”
A few more rough thrusts, and the tightly-strung thread snapped apart like a well-played violin string. Ten came with a gasp, spilling in long, white spurts across the sheets, feeling Kun pulse inside as hot liquid filled his core. God, he felt so full.
Kun mouthed at Ten’s neck, nipping and licking leisurely as they both caught their breath. He spanned his palm across Ten’s belly, pressing lightly.
“So good,” Ten croaked, feeling the weight of Kun’s fading erection move inside. Something wet and hot dribbled down his thigh and he shifted, trying to prevent it from spilling out all at once. He may have let out a disappointed mewl, since Kun pulled him in, cuddling him close, murmuring sweet nothings into his ear.
“You want to keep it?” Kun asked, a shadow of surprise in his tone.
“You–your body spent energy to make it, so…” Ten turned to fix his wide, wet eyes on Kun’s. “It would be a shame to waste.”
All the confidence and bravado that Ten had had before was gone, replaced by a headspace that Kun had seen very rarely in the years they’d been together. How far would Ten allow this to go? He hugged Ten even closer, feeling the ridges of his spine against own warm chest. “You’re right, it would be a shame.”
He paused, then said lowly, “A pregnancy test would tell us if it worked, though.”
Kun felt rather than saw the way Ten’s muscles tensed up, his heartbeat picking up speed, a low gurgling sound in his throat that could be mistaken for a purr, had he not been human. The subtle movements dislodged Kun’s soft cock, and Ten whimpered pathetically at the mess that gushed over the blanket. A feeling of possessiveness washed over Kun. He filed this new information away for later, something to look forward to when they had more time.
“It’s okay, it’s okay,” Kun soothed, petting over Ten’s hair, squeezing softly on whatever piece of him he could reach. He extricated himself slowly, so as to not aggravate Velcro-Ten, to grab a spare towel and a fresh blanket from the en suite. Cleanup was fast, fueled by grabby hands and a lot of whining, and Kun almost wanted to film him, if only to have proof that his normally spicy boyfriend could, in fact, be as adorable and as clingy as dandelion fluff in spring.
He settled into the fresh blanket and grabbed his discarded iPad as Ten wound every limb around his torso.
“Teach me some more lessons, doctor,” Ten yawned, already on the train to dreamland.
Kun pressed his lips to Ten’s forehead. “It would be my pleasure.”
