"Kya!" The mother of Riku and Umi yelped as Fujisawa, known as the Vtuber Pinky, sneaked up behind her and began to grope her massive G-cup tits, each finger sinking into the soft flesh, making her moan from the touch.
"You have a beautiful body here." Fujisawa admitted as she continued to fondle the mother, impressive by the fact that she maintains her appearance even after having 2 children.
After reuniting with Riku with her family from the bokuto wood borer, Tsuyoshi Jinguji and his group would settle in an abandoned house to settle in for the day. While the others were busy lounging, trying to get communications and Inaho Enoki wandered at night to study more bugs, the mother and Fujisawa decided to hit the showers to cool down. Though she had the bigger breasts, Vtuber was more amazed that the mother still maintain her looks after giving birth to Riku and Umi.
"Your breasts are soft to touch." Fujisawa giggled as she pinched one of her nipples while she proceeded to lower her other hand to the tennis player's crotch and rubbing her fingers against her clitoris which made her moan out. "Your moans are cute as well."
'N-No! What if someone sees us?!' The mother thought in panic and tried to say something but the only that came out as moans as Fujisawa dominated her whilst in the showers. She can only slap a hand over her mouth to muffle it.
Suddenly they heard something moving that forced Pinky off the embarrassed mother. "R-Riku?! Is that you?!" The mother yelped, she and Fujisawa covered their breasts in embarrassment as she though her daughter had caught them doing some lewd. A silhouette appeared in the curtains but then it got bigger, too big for either Riku or Umi which made them freak out and causing the former to turn the showers off.
For a while it was silent which made the mother grab a mop in self-defense. Then something lunges at them whilst covered in the curtains. She responds by hitting it which lands a few feet away. After some wriggling, their assailant reveals itself as a massive mountain slug. They gasped as they know that it is. Not only are they the biggest slugs in the world, once you're targeted by one it was nearly impossible to escape thanks to their enhanced senses.
Remembering an experience from before, the mother quickly the showers on. The hot water hits the slug's skin which made it writhe in pain from the scalding heat. "Run!" She yelled as she and Fujisawa began to flee. However, due to the water not being hot enough as opposed to boiling from a kettle, it recovers and began to chase the two females. Seeing it was catching up, the mother turn and beats it with the mop to stall it as Pink ran away to hide.
Seeing it was disorientated from both the hit and the hot water before, the mother turn to follow Fujisawa but gasped in shock as she witnessed another mountain slug entering through the window despite the fact it was too small to enter. Now she was cornered by two slugs with only a mop in hand. Attempting a last stand, the mother began to hit them with everything she has. But no matter hard hard, the slug's soft flesh cushions the blow thus lessening the impact and doing nothing.
Inevitably the mop broke when the mother tried to hit second mountain slug. When she looks at her broken weapon in shock, this gave the first mountain slug the opportunity to wrap around her body. As she screamed out in shock, the second one would also lunge and wrap its body which effectively traps her between them. Seeing the second one's face near her, she raised her broken weapon up and slams it on its hoping to kill it.
Only for it to look at her like nothing happened since the mountain slug's soft body can reduce injuries. "Ah....." This stuns her to the point she loses her footing, falling on her back with the mountain slugs still wrapped around her. She looks the one she failed to kill with fear, scared of being devoured by the massive bug. And yet it merely looked at her and made no attempt to turn her into dinner.
"E-Eh?" The mother is snapped out of her trance when she felt something prodding her entrance, making her blink. She then remembered the first one that ambushed her had its head to her lower body and from the feeling of the shape that was trying to enter her pussy, she knows what it is and and, much to her horror, what it wanted.
"GYAAAAH!" But before she could do anything, the mother screams as something huge and sticky thrusts into her cunt, filling her up completely and began to slid in and out of her in a hard and fast pace. The mother then began to claw on the slug's skin, trying to pull it off her, but the slimy surface made it impossible to get a firm grip. Even as she tried to move or roll over, it remain attached to her. She cried out as she could feel the massive cock stretching her insides wider with every move.
"Eeek!" She looked down and saw the second mountain slug making its move by latching onto her G-cup tits, sucking on them hard. "Ah~! I-It's too much!" Even though the thought of bugs sexually violating her body appalled her, the feeling of a cock in her and her tits getting sucked on turned her on. Her fighting spirit, whilst still fierce, faded bit by bit as the mountain slugs had their way with the mother who can only moan and clutch unto them.
Soon the first mountain slug thrusting its cock into the mother eventually reached its limit, its slimy cock swelling up inside and filling her up with its translucent semen. The mother arched her back and moaned out as she could feel her insides heating up from how much cum was pouring into her. The second one sucking her tits remain in place but held the mother down as its ally inseminates their victim.
A while later and the orgasm died which left the the mother panting and. However. Rather, the slugs did not release their hold on her which made her pale and gulp. The mountain slug that creampied her retracted its cock from her cunt which flowed with rich fluid before moving to another unused hole, her ass. The mother gasped and tried again to escape, but froze as the second one moved its head closer to hers, mouth open to reveal its long, white, slimy cock to her.
Realizing she was stuck between being violated or getting eaten by them, she reluctantly opened her mouth to let the slug's cock slid into her orifice and it was so long she swears it reached down her throat. "MMMMPH!" Her eyes widened and gave out a muffled cry when she felt her ass being opened up at the same time. Then the two slugs began to thrust their massive rods in and and out of her
'F-Fuck~ They're too good at this!' The mother groaned around the cock in her mouth and held onto its owner to control its pace so she can breath properly. Her legs wrapped around the first slug's body and grinded against its body as she felt its cock touching every nook and cranny up her asshole. Knowing there was no hope of her being rescued, the mother gave in to their desires and starts bobbing her head back and forth to suck on the cock while bucking her hips.
Seeing their prey being complicit, the slugs began to pick up their pace, moving their prehensile cocks in her. The mother nearly choked by how fast the slug in her mouth went but managed to find a take in air when she can. Soon her torment ended when the cocks in her ass and mouth swelled up and began to fill her with their essence. "Ghk!" The mother gagged as she swallowed sticky cum while her ass felt like it was on fire from how hot the semen is.
After an intense minute, the slugs eventually retracted their cocks from the mother and untangled themselves from her. She fell on her stomach and coughing up saliva and cum from how much was dumped into her. Her pussy was leaking translucent semen and her asshole gaping a bit which also leaked some sticky cum.
From somewhere, she could hear Fujisawa screaming and moaning, which meant she too was unfortunately caught and likely being breed by the mountain slugs. The mother raised her head forward and weakly reached out with her hand before she felt her herself yanked back by the slugs pulled her back and keep her in place, ready to fuck her again once they've recovered.
"Riku. Umi. Forgive me." She whispered before passing out.
(^)(^)(^)(^)(^)
At the same time it happened.....
"Please don't find me. Please don't find me." Hidden in a locker, Fujisawa was shaking uncontrollably as she tried to remain as silent as possible to avoid getting detected. Even after Riku and Umi's mother distracted the mountain slug to give Fujisawa the chance to escape, she was a few meters away from the corner before she saw two more slugs blocking her way and was forced to the locker area and hide until they eventually left.
"GYAAAAH!" Fujisawa heard the mother screaming which signals she was caught and possibly eaten and tears poured from her eyes as she knew would be next if she didn't escape. Looking through the ventilation, she suppressed a scream as the two mountain slugs found their way to the locker. As they got closer and closer, Fujisawa prayed they pass by and lose interest. An agonizing minute went by before they disappeared from the Vtuber's view, making her breath a sigh of relief.
Only to scream when the locker got jolted and knocked down, causing Fujisawa to be thrown out and into the open. Looking up she gasped as the two slugs towered over her. "No way. They knew I was hiding there?" Fujisawa asked in horror. She was unaware that mountains slugs have an enhance smell that allows them to hunt their prey from a long distance.
Desperate, Fujisawa turns and attempts to run for it but, one of the mountain slugs lunge forward and wrap its body around her left leg, stomach and head. She screamed and fell on the floor as she was being coiled by her assailant like a boa constrictor to prevent her being escaping. "Let me go!" Her fists beat against its skin but against its soft body, it was like a child hitting an adult's leg: Able to feel it but not painful enough to be hurt.
She felt the slug's mouth attached to her head and applied some pressure, making her freeze from the pain. Fujisawa was afraid that any more resistance would result in the mountain slug crushing her head and she reluctantly stopped attacking it which in turn release the pressure but not letting her go. "Eep!" Fujisawa gasped at something slimy between her legs and saw the second slug's head close to her pussy, as if inspecting it. Then without warning, it attaches its mouth to her cunt that made startled the Vtuber.
"H-Hey what are you- kyaaa!" Fujisawa screamed as she felt her cunt stretched wide open by something large and long and sliding in and out like taking something out of its sheathe and putting it back. It took the Vtuber a second to realize it was a cock and that they didn't want her as food but a broodmare. It was also likely the mother's fate from earlier on and Fujisawa would experience it too.
"No no no no no!" She panicked and began to wriggle her lower body violent in the hopes of escaping it. Survival instinct overrides common sense and Fujisawa resorts to hitting the second slug with her legs even with the threat of the slug caving her head in remained. However not only did her kicks failed, but the first slug still didn't kill her. Rather, Fujisawa yelped as something slimy and thick touch the back of her head where the slug's mouth is.
Soon something came out from the side and Fujisawa's eye widened when she saw that a long white and blue cock came in full view of her while noticing the slug's eyes watching her and realized it gave her an ultimatum: submit or get devoured. No matter how repulsive the the idea of consenting to being raped by slugs is, it was infinitely better than becoming their food and a bloodstain for the others to find. Fujisawa's body went slightly limp but still moaned and twitch from the slug screwing her pussy.
Seeing their prey going docile the first mountain slug's cock slithered its way towards her massive H-cup breasts and wrap each one in a coil. Fujisawa was in shock and awe at how truly long a slug's cock is and and gulped as the tip nears her mouth. "Hurk!" She barely opened wide enough for it to plunge into her orifice and down her gullet, making her gag.
'H-Holy shit! It's huge!' Fujisawa moaned out, eyes rolled into her head as the the massive slimy shaft drills through her oral orifice and simultaneously rubbing her massive breasts while her pussy gets filled up at the same time. Drool leaking from her mouth as she was attacked on two fronts. Her hands moved on their own and reach for her own tits and began massaging them which enables her to feel the elongated cock that's wrapped around them. Once in a while she would squeal whenever the second slug's shaft hits her G-spot in the same pace.
The Vtuber had no no idea how long their bizarre threesome continued but it was more than enough when she felt the cocks in her mouth and pussy twitching and began to get bigger and though she braced herself, she was gave out a muffled cry as thick, translucent semen came flooding into her occupied holes. Cum that she can't hold leaked and dribbles from her chin and pussy and unto the floor.
Several more loads later and the slugs' orgasm subsides, but are noticeably still hard. The second on in Fujisawa's cunt remained in position but the one holding her head in a grip began to loosen as well as retracted its cock from her mouth with a pop and untangling it from her giant tits. "Gack!" Fujisawa coughed up a storm when she felt her mouth freed. Getting screwed by slugs was something she did not expect to happen.
She was dazed the she didn't realized that the slug that held her hostage changed its position and flipped over on her stomach until she felt its cock poking at her secondary hole. Fujisawa looked back and saw that it was preparing to plunge its cock deep into her backside. "Oh fuck." Was all she could whimper out before yelling and arching her back as a second cock invaded her second hole and as if triggering a response, both slugs began pumping their rods back and forth with synced movements, one goes in when the other pulls out.
"Kyaa~!" Fujisawa couldn't hold it back and began screaming out as she clawed at the floor as it to get a grip on something as the double penetration sent jolts of shock and pleasure to the Vtuber. From afar, she could hear Riku's mom moaning which proves she too was likely getting the same treatment. The Vtuber decided to grope her own tits again as not be left out, admiring how huge they were and the slime from their slug's cock that coiled on them from earlier.
After what seemed like forever, the two mountain slugs' elongated cocks twitched and starts spewing their load into the moaning Vtuber's vaginal and anal holes, once again translucent cum deposited into her but this time in her ass as well. Fujisawa's eyes rolled into her head and she went limp, overwhelmed by the sensation of her lower holes being pumped by hot cum, from giant bugs no less.
The intense creampie lasts a minute but eventually both slugs withdrew their cocks from Fujisawa. Her asshole quickly closed to prevent cum from escaping but her pussy leaked a lot since there's nothing to plug it in. She had her tongue out and her breaths came out as pants, exhausted and spent from the experience. But then she felt the slugs put their bodies on her back and pinning her in place as if to prevent her from escaping if she had second thoughts. Not that Fujisawa had the strength nor the will do so since it was only a matter of time before more slugs arrive and use her as a breeding sow.
"Heh, maybe I should try a porno about this if we get out of this." Fujisawa muttered weakly with a chuckle, hoping that Jinguji and the rest would be able to find them.
