Under the Kotatsu

Summary:

An otherwise boring study session with your friends takes a stimulating yet nerve-wracking turn as your mischievous kouhai Haachama decides to play with your cock beneath the kotatsu everyone is sat around.

Work Text:

Pencils scribbling across paper. Buttons pressed on a calculator. Hair being clawed at out of frustration. These were the only sounds that could be heard in the main room of your apartment, despite there currently being four occupants. Exams were coming up and you were balls deep into a group study session. You were joined by two of your classmates, Natsuiro Matsuri and Aki Rosenthal; as well as your kouhai, Haachama.

It was chilly outside today, so it was decided to hold the session at your apartment, due to you owning a kotatsu. The four of you were sat around the heated table, eight legs, six of them bare, folded underneath, absorbing the electric warmth. Haachama was sat opposite of you, with Matsuri to your left and Aki to your right. Notepads, textbooks and pencil cases were strewn about the kotatsu’s surface, not a single bit of free space visible.

A cuckoo clock you had once bought as a joke let out its hourly chirp. It had chirped when the study session had begun and had now chirped twice more since then. Two hours were gone and yet you felt you didn’t have much to show for it. A frustrated grunt from Matsuri, followed by her faceplanting into her pages, signalled that you weren’t the only one not getting bang for your buck.

“Hang in there Matsuri!”

Aki spoke in an uplifting tone, trying to keep her friend’s spirits up.

“I don’t get any of this! I think I’m going to throw in the towel.” Matsuri replied, her head remaining face down in her textbook.

“You know, for a cheerleader, you don’t sound awfully cheery right now.” You jabbed.

“Bite me!” Matsuri barked, pulling her face out of the books to get up in your face.

Playful banter ensued between you and your classmates, taking a well-earned break from education. As Matsuri and Aki steered the conversation towards some movie they were planning on seeing later in the week, you turned your attention across the kotatsu towards your kouhai. Haachama was still head down, scribbling away in her notebook. She was keeping quiet. Too quiet. You had a bad feeling…

“Ah?!”

“Is something wrong?” Aki asked, looking at you with concern.

“Y-Yeah! I’m fine! Don’t mind me!”

Aki just nodded, still looking at you with worry but her mood instantly shifted once Matsuri dragged her back into their conversation.

Taking a deep breath, you returned your gaze to Haachama. Her head was resting in her left palm as her right twirled around her pencil. Her eyes were glued to her notepad but for just a brief moment, her gaze shifted towards you. You noticed the left corner of her mouth curl into a smirk before she returned her attention to her studies.

“Little brat…”

Above the kotatsu, Haachama was acting like a well-behaved student, taking her studies very seriously. Under the kotatsu however, she was acting far more depraved. Haachama had extended her right leg over to your side of the table. Her foot slipped between your legs before planting itself upon your groin, applying a noticeable amount of pressure to your slumbering wood. This sudden attack had been the cause of your verbal outburst.

At first, Haachama did nothing more than just keep her foot pressed against your crotch. She was wearing pink fuzzy angora socks. Their soft feel, combined with the warmth and pressure of her foot, roused your cock from its slumber. Once Haachama felt your hardened rod push back against her probing foot, she began to lightly press the gas. You pursed your lips, trying to maintain your cool. The presence of Matsuri and Aki meant that you couldn’t tell her to stop, nor could you get up while you had a hardon. You were trapped, left with no choice but to endure Haachama’s playful torment.

Haachama soon joined the girl’s convo. The three of them yapped away while you kept quiet. Haachama gently massaged her foot against your bulge while laughing with the girls, acting completely natural. And yet, she would shoot you the occasional glance, revealing a mischievous glimmer in her eyes that neither of the others caught.

“Damn brat… I’ll get her back for this!”

*zip…*

Your body stiffened as you heard a sound you desperately did not want to hear. Although you couldn’t see it, you knew exactly what the source of that noise was. Under the kotatsu, Haachama had hooked your zipper between her big and index toes. She began to lightly tug it down, taking multiple agonizing pauses along the way. You prayed that neither of the others would hear it. Fortunately, they were too busy laughing about something that had occurred in class the other day. Using their laughter as cover, Haachama gradually worked down your zipper. Once it was fully lowered, she pushed apart your fly, allowing your erect dick to spring out. You let out a deep but low volume breath as you felt the warmth of the kotatsu brush against your exposed member.

Haachama kept her right foot positioned near your dick but made no direct contact. Instead, she extended her left leg, positioning her left foot on the opposite side of your cock to its sister. Haachama kept her feet hovering barely more than an inch away from your dick. She was waiting… waiting for you to make eye contact with her. You knew this… and yet you were ultimately unable to resist the urge to gaze into those blue pools. Once you did, she clasped her feet together, trapping your phallus between them.

You gritted your teeth together, hands gripping the edge of the kotatsu as you fought off the urge to moan. Haachama kept her feet pressed against your dick but otherwise did nothing. The soft fabric of her socks… The warmth of her soles emanating through them… Your dick pulsated with exuberance, immersing itself in the comforting embrace of Haachama’s feet. Your kouhai watched you with intrigue. She soaked up the expressions of suppressed pleasure and fear of humiliation from your face. God you hate this brat!

“Hey? Are you sure you’re okay?”

“Huh?”

You turned to Aki, who had returned her attention to you.

“Yeah, you’re looking awfully red there!” Matsuri commented.

All eyes were on you. Two pairs filled with genuine concern while the third was filled with malevolent glee.

“Y-Yeah! I’m fine! Just focusing hard on my studies!”

You grabbed your pencil and kept your head down, returning to the books. Aki glanced over at Matsuri who just shrugged her shoulders. Following your que, the girls ended their chat and returned to studying. The room that had been filled with chatter returned to a void of near complete silence. The light sounds of pencil scribbling and page turning were the only things to shatter the fragile quietude.

While things were peaceful above the kotatsu, the same could not be said below it. Haachama lightly stroked your cock, brushing her sock-covered soles along your shaft. The pressure she exuded varied in frequency, as did the form of her strokes. Sometimes they would be perfectly vertical, other times her feet would coil around your dick, only to force your cock to twist around them in turn. Occasionally her toes would curl around your engorged head, gently dragging her nails through its sensitive flesh, the socks doing little to hide their sharpness.

While your cock was the star of the show, your balls weren’t denied their supporting roles. Haachama would repeatedly plant her heels atop your babymakers. She would gently push down on your eggs, lightly rolling them around against the floor, stirring up their warm contents.

Your eyes were burning holes into your notes. Your loins were on fire. You wanted to cum… but you couldn’t cum… not here… If either Matsuri or Aki discovered what was happening under the kotatsu, you’d never live it down!

You glanced over at the clock. Nearly thirty agonising minutes had passed since Haachama began her assault. Just thirty more and the cuckoo would sing, marking the end of the study session… and your torment.

Despite thirty minutes not being an awful lot, each one you endured felt like some form of accomplishment. You were amazed that Haachama was able to keep introducing new methods and techniques to use on your cock. Some of them she might have just improvised from her surroundings. When she saw Matsuri scratching her head in frustration, she began doing the same to your shaft, dragging her nails along its length. When Aki was digging her thumbnail into the rubber at the end of her pencil whilst deep in thought, Haachama mimicked her by digging the nail of her left big toe into your cock slit, lightly scratching the insides of it.

No matter what Haachama threw at you however, you endured it. That said, your resolve was waning, and Haachama knew it. Your cock was pulsating like mad, oozing precum like a broken faucet, staining the soles of Haachama’s socks as they soaked up your product. Your balls felt like they were about to burst from all the backed up cum, not helped by Haachama lightly juggling your boys between her feet. You were at your limit. It was only a matter of time until you blew…

As the clock struck three, three things fittingly occurred. The first was the cuckoo making its entrance, signalling the end of the hour and the beginning of the next. The second was Matsuri suddenly letting out an excited outburst, something in her studies having finally clicked with her. The third was your cock erupting, your limit having been reached.

You held your breath, eyes bulging from their sockets as you fought down every moan, groan and breath you wanted to make. The load you expunged was mighty indeed, borne from an hour’s worth of teasing. You feared it would splash against the girls’ bare legs, but thankfully that fate did not come to pass. Instead, the bulk of your load was soaked up by Haachama’s socks, already stained in her sweat and your pre.

You stared down into your books during the first several spurts, but a firm prod against your cock forced you to look up at Haachama. She was looking right at you, head resting in her hands. Her expression was… normal. A simple smile… A pleasant shine to her eyes… And yet you knew it to be nothing more than a mask. Underneath it all, she was gloating. You had cum under the kotatsu from your kouhai’s feet. It was yet another victory for her.

Your ejaculation finally petering out, you collapsed face first into the table. You had been made into your kouhai’s plaything, and after an hour of torture, you didn’t even get to properly enjoy your orgasm, too busy focusing on concealing it. The one silver lining was that neither Aki nor Matsuri caught on to what had occurred beneath the kotatsu.

Your classmates began packing their things. Matsuri made some jab at you, likely revenge from when you had previously made a jab at her. You ignored her, keeping your face glued to the kotatsu. Aki gave you some encouragement, assuming your frustrations were related to your studies. You appreciated the sentiment, but you really just wanted her and Matsuri to get the hell out of your apartment.

Once the girls had gotten up from the kotatsu and Haachama had withdrawn her feet, you stuffed your slimy shrivelled cock back into your pants. Hauling yourself to your own feet, you showed the girls to the door, your classmates thanking you for hosting them.

Once Aki and Matsuri were gone, you turned back to see Haachama standing there with a smug grin.

“Here Senpai, I have something for you!”

She waited for you to hold out your hands. You considered refusing, but she had already bested you today, so you saw no point in fighting back anymore. With a sigh of defeat, you held out your hands. With your palms outstretched, Haachama dropped something heavy and sticky into them. It was her socks, heavy and soaked with your cum. Glancing down at her feet, you saw that she was wearing a fresh pair of socks. Had she planned this from the beginning, or was it just a coincidence that she had another pair with her today?

“Have fun with those Senpai! 😉 I’ll see you later!”

Haachama raced past you, planting a quick peck on your cheek as she ran out the door, shutting it behind her. You were now all alone in your small apartment. Staring off into space, your face weary and drained, you slowly raised your arm, pressing the soiled socks against your face. You inhaled deeply, taking in the scent of your cum and Haachama’s foot sweat. Their fragrances blended together into something most rapturous!

Your dick hardened up once more, acted as a guiding rod towards your bedroom. Shedding everything from your body, you fucked those socks, picturing them as Haachama. You pumped a salty load into each of them, envisioning a scenario where you creampied Haachama, knocking her up with your brats.

Exhausted and weary, you tossed the cum filled socks onto your floor, a heavy wet plop echoing off your bedroom walls as you rolled over onto your stomach to get some shuteye. You tried to fall asleep but the weight of your body atop your cock reminded you of Haachama’s feet pressing against your phallus.

The sleeping position ruined for you; you rolled over onto your back, letting out another defeated sigh as you tried to drift off. Three loads… Three loads she had harvested from you today, and she had only been directly responsible for one! That fact ate away at you as you slipped into unconsciousness.

Time passed, and the cuckoo’s chirp echoed out once more, signalling the end of another hour, although you were clueless as to how many you may have slept through. You felt slimy as you awoke. Sitting up, you found your cock stuck to your stomach, your chest and abs caked in nocturnal emission, no doubt as a result of today’s events plaguing your dreams.

*sigh*… Four loads…”
