Loki whimpered as the cold paper crinkled beneath his diapered bottom, fingers twisting in Mobius’s sweater vest. The fluorescent lights buzzed overhead like angry hornets while the caregiver’s aftershave - sandalwood and something medicinal - clogged his nostrils every time he buried his face against the man’s chest. “Shhh, sweetheart, it’s just a check-up.” Mobius’s hand slid under the hem of Loki’s onesie, warm palm settling on the small of his back. “Remember how we practiced breathing? In through the nose-“ A polished stethoscope pressed against Loki’s sternum before he could obey. Doctor Renslayer’s perfume smelled like lemons left to rot. “Heart rate’s elevated. How long has he been this clingy, Mobius?” Her gloved fingers peeled back his left eyelid, the light she shone making colors explode behind his clenched teeth. “Since breakfast.” The vinyl exam table squeaked as Mobius repositioned the squirming bundle in his lap. Loki’s toes curled inside thick white socks, legs automatically splaying to accommodate the bulk between his thighs. The diaper’s plasticky outer shell whispered secrets every time he moved. “Been trying to rock him down for naps but he just- ah! Careful, those nails are sharp today.” Loki’s incisors dug into the meat of Mobius’s shoulder through the sweater as the doctor’s hands slid lower. “Tsk. Still sensitive about the hips.” The sudden flip onto his stomach pressed Loki’s padded crotch into Mobius’s thigh. Cold air hit his bare back as onesie snaps popped open. “Have you been doing the compression massages I showed you? These muscle knots could-“ A high-pitched wail tore through the room as Renslayer’s thumb found the dimple above his right buttock. Mobius’s arms locked around the writhing form. “He’s due for a change. Maybe we should-“ The doctor snapped her fingers three inches from Loki’s nose. “Look at me, little prince. That’s it. Big breath in…” Her maroon-tipped nails tapped the swell of his diaper. “We’ll need a stool sample first. Your choice - swab or manual stimulation.” Mobius’s Adam’s apple bobbed against Loki’s temple. “He, uh… he hasn’t... You know he holds it when he’s anxious.” “Then we’ll help him relax.” Renslayer peeled the diaper’s left tapes with clinical precision. The scent of lavender powder bloomed in the stagnant air. “Turn him face-up. Legs elevated.” Loki’s socks left skid marks on the paper as Mobius maneuvered him into position. The first q-tip grazed his entrance, dry cotton catching on delicate skin. “Wait!” Mobius’s knee jerked, accidentally jostling the exam table. A tongue depressor clattered to the floor. “Couldn’t we… maybe try the other method?” The doctor’s sigh fogged her round glasses. She lifted Loki’s t-shirt, exposing the pale plane of his abdomen. “Deep tissue only works if you commit, Mobius. Watch closely.” Her fingers spiderwalked clockwise around his navel. “Start here with gentle pressure… then spiral outward…” Loki’s toes curled as knuckles dug beneath his ribcage. His back arched off the table, a thin whine slipping through gritted teeth. The onslaught continued - kneading, pressing, rolling flesh that’d never felt anything but tender caresses. “There we go.” Renslayer’s thumb pressed hard below the belly button. Loki’s legs shot out straight, heel connecting with Mobius’s shin. A warm mushiness spread beneath him, the telltale squelch making his face burn. “Perfect consistency for sampling. Hold his hips up.” The diaper sagged open like a split peach as the doctor inserted two gloved fingers. Loki’s scream died when Mobius shoved a pacifier between his lips. “Scooping from the perianal region…” Renslayer muttered, twisting her wrist. The q-tip emerged streaked with brown. “Now the other sample.” Mobius’s grip tightened. “We discussed maybe skipping-“ “Regulations require semen analysis with this vaccine series.” She peeled off soiled gloves with a snap. “Unless you’d prefer catheterization?” Loki’s whimper vibrated through the silicone nipple. His legs trembled as Renslayer’s fresh glove descended on the swollen outline in his diaper. “Focus on the frenulum first.” Her fingers molded the bulge through crinkling plastic. “Use the heel of your hand for rhythmic compression…” Hot shame pooled in Loki’s gut as his traitorous body responded. The pacifier fell from slack lips when she thumbed his tip through the padding. “There’s the precum staining. Now alternate pressure points…” Her free hand pinned his hips as the diaper tented obscenely. “Pay attention, Mobius. You’ll need to replicate this technique during-“ The door burst open. “Apologies for interrupting!” A nurse clutched a clipboard to her chest, eyes locked on the ceiling. “Doctor, there’s an emergency cyst aspiration in room seven that-“ Renslayer wiped her hands on a fresh towel. “Take over here. Ensure Mobius understands the proper massage method. Full sterile protocol.” Mobius’s protests died as the nurse snapped on gloves. She flipped Loki’s onesie up to his chin, exposing the leaking diaper. “Like this, daddy.” Her lacquered nail traced the weeping outline. “Gentle circles here… then upward strokes…” Mobius’s palms grew slick against Loki’s feverish skin. “Maybe he needs privacy-“ The nurse’s hand dove into the diaper’s gap. “Infants can’t masturbate alone. Don’t you want him to learn proper self-care?” Her thumb swiped through the sticky mess. “Now you try. Left hand supporting the sac, right thumb rolling the shaft.” Loki’s scream twisted into a moan as Mobius’s calloused fingers closed around him. The nurse guided the caregiver’s wrist through pumping motions, her perfume cloying as she leaned over their tangled limbs. “Faster… yes, feel that ridge? Apply pressure when he tenses…” The world narrowed to Mobius’s panicked breaths and the obscene squelch of lubrication. Loki’s back arched, toes curling as white-hot pleasure crested- “Squeeze the base! Don’t let him finish yet!” Mobius’s thumb clamped down, turning Loki’s cry into a choked sob. “Good. Teach him to edge. Stamina is crucial for proper colon health.” The nurse swabbed Loki’s leaking tip, depositing the sample in a vial. “Now for your turn.” Mobius froze. “My…?” “The clinic’s new partner program requires caregiver hormone panels. Drop your pants.” The nurse’s acrylic nails tapped the exam table. “Semen collection only. On your back.” Loki squirmed upright, suddenly forgotten. His soiled diaper sagged open as Mobius unbuckled his belt with shaking hands. “Wait.” The nurse pressed a cloth against Mobius’s tented briefs. “Through the fabric. For accuracy.” Her hand slithered into his pants, knuckles distorting the khaki fabric. Mobius’s sharp inhale hissed through clenched teeth. “Prostate congestion reduces sperm motility.” The nurse’s fingers kneaded his groin like bread dough. “Full expression requires digital stimulation.” Her pinkie hooked in his waistband. “Relax the sphincter, daddy. This’ll feel tighter than Loki’s-“ “Don’t!” Mobius’s hips jerked away. “He’s right there!” Loki’s pacifier clattered to the floor. “Daddy’s bottom?” The nurse’s laugh sounded like breaking glass. “Who do you think milks your bottle every night, starshine? Big boys need checkups too.” A gloved finger breached Mobius with no warning. He braced against the wall, face flushing crimson. “Tsk. Engorged.” The nurse twisted her wrist. “Let’s practice together, Loki. Tell daddy what my hands are doing.” Loki’s legs swung off the table. “Finger… in daddy’s butt?” “Deep breaths.” White spots danced behind Mobius’s eyelids. “Just like - ah! - breathing exercises.” The nurse crooked her finger. “Feel that walnut shape? Apply steady pressure here…” Mobius’s knees buckled. A pearly string oozed into the cloth. “Again.” Her thumb pressed against his perineum. “This cord connects to the-“ “Balls!” Loki clapped powder-smudged hands. Mobius’s strangled moan shook the cabinets. The nurse collected every spurt with clinical detachment. “Good prostate yield. But…” Her hand emerged glistening. “Who’s been neglecting your sack squeezing, daddy? These testicles...” Loki leaned in, nose wrinkling. “Blue?” The nurse’s slap rang out before Mobius could react. His bare asscheek flushed scarlet. “Rule number one.” She dragged Loki off the table. “Swollen glands get punished.” Loki’s palm connected with Mobius’s other buttock, leaving a sticky handprint. “Harder.” The nurse guided his wrist. “Like spanking messes out of diapers.” Mobius’s tears splashed the tile. The crack of flesh on flesh synchronized with the nurse’s metronome-like commands. “Arch the back… alternate cheeks… now a full volley!” Chaos dissolved into sobs. Loki’s handprint bloomed red as he suddenly froze, pupils dilating. “Mobius?” Adult baritone shattered the nursery air. The nurse stepped back as Loki vaulted off the table. The pacifier rolled under cabinets while shaky hands zipped trousers. Their foreheads pressed together, salt and regret mingling in shaken breaths. A sterile knock interrupted before either could speak. “Forgot the constipation questionnaire!” The nurse brandished a clipboard. “How often does Mobius finger your anus, Mr. Laufeyson?”

Loki, a diapered and anxious child, undergoes a thorough medical examination by Doctor Renslayer, with Mobius assisting, that includes a stool sample and a semen analysis. The nurse interrupts and takes over, instructing Mobius on proper massage techniques for Loki's self-care and then proceeds to perform a semen collection on Mobius, with Loki's assistance. The nurse then punishes Mobius for swollen glands, with Loki spanking him.



Loki whimpered as the cold paper crinkled beneath his diapered bottom, fingers twisting in Mobius’s sweater vest. The fluorescent lights buzzed overhead like angry hornets while the caregiver’s aftershave - sandalwood and something medicinal - clogged his nostrils every time he buried his face against the man’s chest.

A gloved finger breached Mobius with no warning. He braced against the wall, face flushing crimson.

“Forgot the constipation questionnaire!” The nurse brandished a clipboard. “How often does Mobius finger your anus, Mr. Laufeyson?”

A caregiver, Mobius, accompanies his Little, Loki, to a routine check-up where the doctor requests intimate samples, including a stool sample collected through manual stimulation and a semen sample collected by massaging Mobius through his diaper. Loki, in a newborn headspace, observes as the doctor milks Mobius's prostate and teaches him proper self-care techniques, leading to a spanking session and a shift in Loki's headspace. The nurse continues the examination, focusing on constipation and caregiver intimacy, culminating in a detailed interrogation about their intimate practices.
