Will was surprised to still be alive when his eyes snapped open in a panic. Once the monster that had hunted him all week finally found him in Castle Byers and destroyed the wooden fortress, Will accepted his imminent death.
Nancy's friend had only lasted a few seconds after the monster got her. Will heard her screams each time he shut his lids and lay his head down to rest, no matter how loud he hummed The Clash.
He was supposed to be dead and eaten. Instead, he opened his eyes to new horrors. His limbs held still. Wrapped in wiggling vines that encircled his entire body. The never-ending lengths trapped him firmly in their grasp.
Things went from bad to worse when a smaller vine trailed up his chest to poke at his bottom lip. Silent salty tears spilt down his cheeks as he desperately tried to free himself from the vines.
He tugged ineffectively as the vines tightened, the pressure cutting off Will's circulation and making him faint. He soon ceased his escape attempt, and the vine stroked his cheek as if in approval.
“Please-“ Will gathered the courage to beg when the smaller vine took advantage of his opened mouth and slipped inside its warm cavern.
Will's eyes widened in shock and horror as the vine pushed deep into his mouth, squirting over his tongue, and continued to the top of his throat.
He had only a second to prepare before it thrust into his throat. Only the thinness of the vine allowed him to breathe around the obstruction.
He was so preoccupied with not choking on the vastest thing that had ever been inserted down his throat to notice as another vine had started pawing at his pants.
Two of the hugest vines were wrapped around each leg, and they decided; in unison, to spread them in opposing directions while a third prodded at the seam of his pants.
The shabby material of his brother's hand-me-downs couldn't compete with the persistent vine, especially not after having been degraded by a week in this god-forsaken place, and the material tore in one fell swoop.
The tighty-whities did nothing to protect his sensitive skin from the cold air and even little as the vine resumed its prodding and poked along the bottom of his underwear.
Will wanted to squirm away again as the vine breached the sagging bottom of the briefs and slipped to his bare ass-cheeks. He was too scared to disrupt the vine that had lodged itself down his throat in fear of choking to death.
The tip of the vine that caressed his ass left behind a slimy substance as it rubbed over his cheeks; Will was dismayed to realise the same substance was being pumped down his throat from the enclosed vine there.
Even his terror wouldn't have kept him still as the vine on his ass moved between his cheeks and poked at his hole if it hadn't already rendered him frozen.
He could only whimper around the obstruction in his mouth, the vines tightening around his limbs, as the leaking tip of the vine between his cheeks pushed up and breached the curled rim of his ass.
The gasp was forced from his lips despite the girth that kept them muffled as the vine didn't stop its motion and ventured deeper inside a place that had never been entered.
Will was filled from both ends and kept perfectly immobile by large vines, and they started to pump in rhythm as Will wept helplessly.
He wished he had been eaten instead of this, and it was only the beginning.
The vines leisurely thrust in and out of him, both tips pumping their liquids freely until Will's little belly began to bloat. The thick substance flowed down his throat and filled his stomach as the liquid pumped in his ass eased the vine's way and helped temper the pain.
The pain was all-encompassing when the vine first shot up his bum and slowly became easier to handle. A treacherous part of his mind admitted it was slowly becoming pleasurable instead.
The same part of his mind that encouraged him to suckle off the vine in his mouth to suck out more of the sweet substance that clouded his mind with delirium.
So intoxicating was the taste that Will found himself losing time in the haze and instinctively rolling his hips back onto the vine that impaled him.
He mewled vocally around the obstruction when the vine breached him anally and struck a spot inside him that lit fireworks off behind his eyes. He desperately sought to repeat it and failed to notice the tip of the deeply embedded vine begin to widen.
Only when it was over three times the diameter of what had first been shoved up his passage did Will realise and the fear return in full force.
He wanted to scream 'wait' at the mindless vines that wouldn't have listened otherwise when he began to feel the slimy vine pulsate erratically.
His legs were pulled painfully apart, and the pressure at his rim rose rampantly as something butted against it inside the vine.
The bump in the vine pushed harder against the stretched skin of his rim and eventually popped through the tight hole and rested just inside Will.
It felt like the size of a small melon, and he wasn't given any time to adjust as it continued up through the vine and deeper inside Will as well.
His eyes leaked more tears as the pain exploded the further the ball was pushed inside until he felt it reach the furthest depths the vine had reached.
He expected it to either remain in place or start to retreat back when the object was expelled from the head of the vine and implanted deep within his bowels.
Will's stomach descended with the deposited mass, and he didn't have a chance to freak out when the pressure began again at his rim with a new bump seeking entrance.
His jaw dropped in an attempt to scream, but a second vine was shoved in his mouth to muffle any sounds, and the new ball slipped into his hole and up into his bowels.
The vine lodged in his ass deposited several more hardened egg-like objects inside him as Will's belly got bigger and bigger. So big that the vine wrapped around his stomach had to get looser and looser.
He was stuffed so full that even if the vines released him, he wouldn't be able to run away. A waddle at this point would be expecting too much.
It was no surprise that when it was finally over, and they released their tight grip, Will only had the energy to fall forward onto his knees and cradle his humongous belly.
He looked like Mike's mom when she had his little sister, and Will coughed as he took his first unobstructed breath and stared at his gigantic stomach in disbelief.
As he was coming to terms with his new situation and not yet ready to deal with it, a new problem arose in the form of the monster that had hunted him for a week returning.
Will was even less well-equipped to fight now. Exhausted and stuffed full of some unknown things. He could feel how they banged together inside him, the soft surface of their egg-shaped form pressed into the soft velvet of his insides.
Will tried to crawl back as the monster slowly sniffed the air and began to approach him. He had one hand on his voluptuous stomach as he squirted across the ground.
He didn't get far when the vines that had fallen dormant on either side of him reawakened at once and tightened around both his ankles. They pulled him to an abrupt halt, and Will was trapped as the monster got closer.
He closed his eyes, and fresh tears streamed down his face as he felt the disgusting breath of the creature atop his head and braced for the feel of teeth to rip their way through the back of his neck.
They didn't come. Instead, the pungent breath moved lower down his body, sniffed up his stretched stomach and almost purred in approval before continuing even lower down his body.
The monster stopped at Will's bare ass, and he shivered as the monster exhaled over his leaking and widened hole. The damage the vines left behind was evident to the creature as it seemed to examine him.
Will trembled in fear under the observation, and his hole desperately tried to close, winking in the monster's face. Or what Will assumed passed for a face.
Will didn't know what the monster was looking for, but it must have found it as it moved away after only a moment before a heavy weight settled over Will's diminutive frame.
He buckled into the ground, his swollen stomach pressed painfully into the floor and the creature atop him. He screamed as an appendage even wider than the vine pushed against his sensitive and rubbed raw rim.
The monster didn't care about his discomfort and ignored his whining and whimpering, inserting its mammoth cock inside Will with one thrust.
The tip of the creature's cock reached the depths of Will's bowels where he was filled with the vine's earlier deposits, and started to jostle the collection with its thrusts.
Will could do little but be dragged across the ground as the monster sought his pleasure with Will's body. His ministrations were even more forceful than that of the vines prior.
The creature's growl echoed around them, and the steady stream of saliva dripped down Will's back and shoulder as it drooled atop him.
Will greedily accepted the vines' return to his mouth as it prodded at its lips. The juices it produced were the only respite from the pain the monster inflicted on his insides, drinking down the nectar until his head went fuzzy and his body lax.
He suckled on the vine as his head rubbed along the ground and his arms cradling his distended tummy. He felt the now-familiar pressure of a large object start at his rim, but unlike the vine, it didn't exit the monster's cock.
Instead, it functioned as some kind of lock, trapping the gigantic dick inside of him as the creature started to cum. Copious amounts of seed spilt from his tip and coated the egg-like objects that settled in his deepest regions.
His insides felt as slimy and slick as the outer coating on the vines, and Will rippled with pleasure from the inside out as his stomach got even larger.
The monster's cock continued to stream with fluid, and the only thing stopping it from escaping Will's permanently gaped hole was the large knot that kept him sealed.
Will eventually lost consciousness, with the distant sounds of his name being shouted from far away.
