The Pocket of Eternal Rest
9:47 p.m.
The door of the Water-Blue Secret Storehouse slid open with a soft whisper, and a massive man with his hood pulled low stepped inside.
The shopkeeper rose slowly from the sofa and offered a gentle greeting.
"Welcome, Commander. You look... rather desperate today."
Cairen von Walthaim pushed back his hood and let out a low breath.
"...I came carefully so no one would notice, yet you still recognized me at a glance."
The moment he sat on the sofa he crossed and uncrossed his legs again and again. The front of his trousers already strained in a clear, heavy bulge; he pressed a hand against it and clenched his teeth.
"The onahole I bought last time barely helped. Ten times a day is the bare minimum now. I can't even function properly. At this rate I'll have to... give up the commander's seat."
The shopkeeper studied the front of his pants with a languid, sultry gaze, set her teacup down, and gave a quiet nod.
"You said your libido was excessive, but if even the previous item couldn't settle it, it must be truly severe."
Cairen managed a weak laugh.
"Healing magic, holy rites, herbs... I've tried everything. It only gets worse... Haah... Isn't there any better solution?"
"Of course there is, hoho."
She rose unhurriedly and opened a drawer behind the display case. What she drew out was a silver silicone pouch no larger than a palm. The exterior looked like soft leather; the interior was coated with a transparent magical membrane. A thin securing belt and a small mana switch hung from one end.
"This is the Always-Wear Dimensional Link Onahole. I named it the Pocket of Eternal Rest."
Cairen's eyes narrowed.
"...Always-wear type?"
The shopkeeper held it up and continued her calm explanation.
"Insert your cock into this hole and it connects this space to another space in a different dimension."
"A subspace!"
Subspace magic belonged to the Twelfth Rank. Academic study alone was difficult enough; ensuring safety and achieving a usable implementation was harder still. Mages capable of creating a practical subspace could be counted on one hand.
"You're saying it truly has subspace magic woven into it?"
"Oh please, this is a top-grade piece I designed myself. Have you ever seen me lie? Don't rush me so, Commander."
She brushed the switch lightly.
"Once your cock enters the subspace it will be sheathed inside a specially engineered onahole. The moment erection is detected, piston motion begins automatically. Speed, depth, rotation—everything is kept at the exact level that feels best for the wearer, driving you perfectly to the edge of climax and then delivering the peak at the perfect moment."
The knight commander's already-hard cock throbbed with anticipation.
"Ah, of course you can't just climax whenever you please. So I designed this remote with a single switch that lets you freely turn it ON or OFF at any time. Oh, and it doesn't accept urine—you'll still have to relieve yourself separately."
Cairen's breathing grew rougher by degrees.
"...Wouldn't it be dangerous to wear that inside my underwear all day?"
"Oh come now. The instant you put it on it flattens completely—nothing shows through the trousers. Walking, running, praying, sitting in meetings... you can satisfy your lust anytime, anywhere, while living your normal life. Just flip the switch when you need it."
She moved behind him, held the onahole up for him to see, and whispered against his ear. Her warm breath tickled the lobe and stoked the heat already coiling in him. Then she offered the device to Cairen.
"One month's rental is fifty gold. Pay and you can wear it right this moment; if it doesn't suit you, return it whenever you like."
Cairen turned the thing over in his hands for a long while. The shopkeeper gave his back another gentle push.
"Would you like a trial right now?"
"......Can I try it immediately?"
She nodded with a smile.
"Of course. Since it's your first time, I'll help."
Before he could protest she was already on her knees. She stripped his trousers and underclothes away, then wrapped both hands around the thick, vein-ridged cock standing fully erect. Hot heat flooded her palms.
"Before we put it on... I should make it nice and slick. It won't go in smoothly otherwise."
Cairen's breath hitched, then broke out rough.
"...W-what are you—"
"Ha... mmm..."
She had already lowered her head. The tip of her tongue flicked lightly over the glans; his thighs jerked. Slowly she sealed her lips around the head and began to take him into the warm, wet heat of her mouth.
Slurp... smack... smack...
"...Haah...♡"
She rocked her head, curling her tongue to stroke along the shaft. She pushed deep, then drew back slowly, tapping the slit with the tip of her tongue. When she swallowed him again, thick with spit, her throat tightened around him.
"Ugh...!"
Cairen instinctively reached for her hair; she caught his wrist at once and set it on her shoulder—a silent order not to move. She quickened her pace, sealed her lips into a vacuum, and spun her tongue rapidly. Spit overflowed and ran down the shaft. One hand gently kneaded his balls; the other gripped the root and stroked.
Smack smack... squelch... smack smack...
When she took him to the hilt she deliberately gulped, squeezing her throat. Cairen's hips snapped forward, ready to spill.
"Haah... if you do it too... hard...!"
But she stopped the stimulation with practiced ease and slowly drew him free. A long, clear strand stretched between her lips and the glans before it snapped. She licked her lips and spoke.
"That should be slippery enough. Now we can put it on."
Still panting with the frustration of a denied climax, Cairen could only nod. The shopkeeper took the onahole and began to ease the spit-slick cock inside.
Slap—
The moment it was fully seated the onahole flattened instantly and clung flush to his pelvis. She cinched the belt tight and pulled his underwear back up; outwardly there was no trace at all.
She rose and met his eyes directly.
"Now... shall we run the real test?"
Cairen's hand trembled as it found the remote's switch. A faint blue rune glowed.
"...May I... turn it on?"
She smiled with playful mischief and laid her hand over the back of his, the one holding the remote.
"Of course."
Together they pressed the switch.
Woooom——
A soft vibration hummed as the onahole began to tremble. Cairen's eyes flew wide.
"...Ugh?!"
Beyond the dimensional link the interior answered at once. Soft flesh clamped tight around his cock and began to stroke up and down. At first slowly, exploring. Then the speed climbed sharply.
Slurp... slurp...
His knees buckled where he sat. He clutched the sofa backrest; his thighs spasmed.
"Haah... t-this is...!"
The shopkeeper slipped right behind him, watching from inches away. Her wicked crimson eyes glittered with delight.
"You feel it, don't you? The inside molding itself exactly to your shape."
Her breath brushed his ear as she took hold of the iron chain fastened to the rear of the sofa.
"Squeezing, sucking, twisting... it will drive you all the way."
The piston grew fiercer. It crushed the glans hard, then released, again and again. Cairen's hips began to rock in tiny, instinctive thrusts.
"Haah... haah... good...!"
"You still haven't come. If I take it to maximum... you'll finish in under thirty seconds,"
she whispered against his ear.
"If you want to cum... just say so. One little push of the switch and you'll climax right away♡."
When he moaned and nodded she pressed the switch all the way up.
Woooom——!
The piston exploded into a frantic rhythm.
Slurp-slurp—!! Slurp-slurp-slurp!!
Cairen's eyes rolled back.
"Uwaah...! No—!"
Orgasm hit and his hips slammed forward. His ass lifted clear of the sofa as he drove his pelvis out with desperate force—exactly the motion of trying to bury himself to the womb of some imaginary cunt.
"Haeuugh——!!"
Hot seed burst out in a violent flood. Even while he came the onahole never stopped; it kept milking, wringing every last drop. His whole body shuddered and locked, hips still thrust out and rigid.
"...Haah... I... I came...?"
He tried to catch his breath and let his hips sink—
The onahole that had seemed to slow for an instant roared back to full speed. Now it focused on the hypersensitive glans right after climax, pounding faster, deeper, harder.
"Ugh?! Again... again...?!"
His hips jerked once more. The raw, overstimulated head hurt so sharply he reflexively reached for the remote to shut it off. The moment the second round of pistoning began, the shopkeeper seized the wrists still gripping the sofa and snapped the iron chains around them, binding him fast behind the cushions.
"It isn't over yet, Commander♡."
The piston grew even more savage. Interior flesh bit down, twisted, crushed the glans and released in relentless cycles. Cairen's pelvis convulsed forward and back.
"Ha... haah...! Please stop...! I'm going to cum again...!"
She lifted his chin and gazed into his unfocused eyes.
"You said even ten times a day wasn't enough, didn't you?"
She nudged the switch one more notch higher.
"Two times should be perfectly fine♡."
Slurp-slurp-slurp—! Sloooorp!!
Broken moans tore from his throat. His hips thrust out again; he twisted, half-rising from the sofa, trying desperately to pull free—but the onahole locked inside his underwear never released him. His body heaved halfway up, then collapsed, over and over. The chains bit into his wrists until the flesh whitened, yet even that pain was lost in the storm.
"Haah... haah... please... turn... turn it off...!"
His voice cracked; the world blurred. Before the aftershocks of the first climax had faded, a second orgasm ripped through him. This time his pelvis jerked in near-convulsive spasms.
"Uuuughghgh——!!"
She tilted his chin again and studied the dazed eyes.
"Still moving, I see. Even after cumming twice you're still standing rock-hard, Commander."
She watched the trembling knight commander for a moment longer, then finally switched the device off and unlocked the chains. Cairen collapsed onto the sofa with a broken, ragged sound. The shopkeeper wiped the sweat from his brow and spoke softly.
"With this onahole you can keep enjoying yourself like this all day long."
"During prayer, during meetings, even in the middle of battle... just flip the switch and you can spurt and spurt without a soul knowing."
Cairen muttered in a shaking voice.
"Haah... haah... this... how much was it again?"
She laughed lightly and straightened his clothes.
"Fifty gold, customer! Come by anytime if you need more help."
Cairen signed the contract, dropped fifty gold on the table, and staggered out the door.
The moment it closed, the blue-haired shopkeeper—Elion—spread her legs on the sofa, replaying the knight commander's moans in her mind. She slipped a hand beneath her skirt and slowly stroked her already-soaked pussy.
"Haah... even a human knight commander is adorable♡...... That aside, cumming twice in a row like that... Ruby must have loved it too, hmm?"
