Mizuhara opens her eyes to find herself inside of a girls room that isn't hers. She doesn't remember what happened but when she moved Mizuhara found that her legs and arms were tied and a pair of panties were stuck in her mouth. Mizuhara looks around and sees her friend Sumi naked on the ground in the same position to her right and on the other side of her Ruka also nude and tied up.
 "What the hell is going on" thought Mizuhara
 With this collection of girls Mizuhara thought maybe Kazuya finally went over the edge and did this but this room was definitely not his. Sumi and Ruka woke up and tried moving and found themselves in the same situation. They couldn't talk to each other at all unless in muffles. Finally footsteps like someone going upstairs came. They got closer and closer until the door opened and the blonde girl named Mami came through. Mizuhara and Sumi recognized her but Ruka had no idea who she was.
 "Oh great you're all awake I just went got everyone out of the house so know I can dispose of most the others having around Kazuya, I've already decided your fates and only one of you will be alive when I'm done" said Mami
 Mizuhara and the other two got very scared from that statement and struggled in their restraints.
 Just to add fuel to the fire Mizuhara I decided to let you live and suffer forever as my sex toy, the rest of you will only suffer a little but then it'll be over...its truly a better fate then being my play thing" said Mami
 Mami went to Mizuhara and got her to sit down on her ass looking up. Mami removed the gag and Mizuhara spat at Mami.
 "You bitch let us go...I'll never forgive you" said Mizuhara
 "Yeah whatever I'll need to shut that trap up...Ruka your up next" said Mami
 Ruka cried out while gagged still as Mami lifted Ruka up. Mami got Ruka in front of Mizuhara and Mami stuck Ruka's feet in Mizuhara's mouth while she talked.
 "That's right shut your whore mouth" said Mami
 Mami pushed Ruka's legs further forcing Mizuhara to gulp. Ruka's eyes widened as Mami planned to feed her and Sumi to Mizuhara and have them get digested. Ruka squirmed as Mizuhara was forced to swallow the bottom half of Ruka's legs. Ruka's jiggly thighs touched Mizuhara's lips and the throat pulled them further. Mizuhara started to cry as she didn't want to eat Ruka and Sumi. It was painful to know that she herself would end up killing them. Mizuhara's belly bulged with Ruka's legs as Mizuhara swallowed the fat ass of Ruka.
 "Half way there just gulp this stupid slut down and churn into mush to absorb" said Mami
 Mizuhara swallowed and swallowed, getting Ruka's flat belly down and she felt Ruka's large breasts touch her face. Ruka whimpered and winced as her nipples rubbed against the inside of Mizuhara's mouth. Mami let go of Ruka and pushed against her head flattening the ribbon she had on. A muffled cry came from Ruka as her entire head was placed into Mizuhara's mouth. Mami quickly removed her hand from Mizuhara's maw and watched with a smirk seeing the final bulge go down Mizuhara's gullet. Mizuhara's gut ballooned out and felt so bloated and full. Ruka squirmed in her belly which made something come up.
*bwarrrppppp*
Mizuhara burped and Ruka's blue ribbon splat on the ground in front of Mami.
 "Now that you are full of Ruka, its Sumi's turn but she won't be in a human shape going down your throat" said Mami
 The bloated Mizuhara looked up at Mami in confusion as Mami took her green skirt off. Mizuhara's eyes widened seeing a bulge in this weird type of panties. The panties came off and a large dick slapped the ground. It rose up as Mami stroked her giant four foot girthy cock. Mami smirked seeing the surprised look of both Mizuhara and Sumi.
 "I had to have a special kind of underwear made for this but I have tested shoving large things through the hole and it works great, my balls will churn anything into cum...of course Kazuya doesn't know and something like that won't hurt him if he doesn't know" said Mami giggling
 The shadow covered Sumi and Mami looked down at her with a smirk. Mami bent over and grabbed Sumi by the hair and pushed her against the tip.
 "Lick it" said Mami
 Mami took the panties out and Sumi cried as she licked the large tip. The tip was bigger than Sumi's head but she licked the entire slathering it in her saliva. Mami breathed heavily feeling a climax coming.
 "I'm going to cum" moaned Mami
 Mami's dick moved and a large glob of cum shot out of her cock and drenched Sumi in it.
 "Not that my balls are empty they'll quickly melt you into a new batch" said Mami
 With that Mami shoved Sumi's head against her cock hole and it opened up. Sumi squirmed and her screams were muffled by the inside of Mami's dick. The greedy giant cock sucked in Sumi's small frame and her small chest slid into Mami's shaft.
 "Oh fuck that's right slide through my cock" said Mami
 Mami unhanded Sumi and let the rest be dealt with by her penis. It sucked the entire first half of Sumi and Mizuhara could see the vague form of Sumi screaming going down Mami's shaft. As Sumi's ass got gobbled up Mami's balls started to bulge and her bigger with Sumi getting inside of them. Sumi's legs kicked until finally her feet slipped into Mami's dick. Sumi's whole body slid through the shaft and she landed into the balls where very few remnants of cum were left. Mami smiled and then started to stroke her cock. Sumi cried as she pushed against the balls. Cum drenched her body and she felt softer. With Mami stroking her giant dick the churning of her balls increased. Sumi only had around five minutes before she would be only cum sloshing inside of Mami's balls. Sumi's legs melted into cum and the balls were filling her melted body.
 "Kazuya...please" said Sumi softly
 Sumi reached up as her body sank into the cum. Her torso melted away and she closed her eyes. Her head went under and her arm fell. Mami felt her balls fill with cum and wondered if any bones were left.
 "She's ready" said Mami
 Mizuhara looked at the balls and saw no form and as Mami came over to her Mizuhara heard the sloshing of gallons of cum in her balls.
 "Open wide for me" said Mami
 Mizuhara forced her mouth open and Mami stuffed the entire tip in her mouth. Inside Mizuhara's stomach Ruka was curled up covered in digestive acids. Her body was a bit soft and it hurt alot. Ruka cried, wanting Kazuya to save her but then she heard something weird. It's as if something was inside of Mizuhara's mouth. Mami stroked her dick faster and faster and looked Mizuhara in the eyes as she was about to cum.
 "I'm cummingggg" moaned Mami
 The Sumi turned cum was shot into Mizuhara's mouth and she was forced to swallow it. Ruka heard gulps and then cum splattered all over her body covering her. Sumi's broken skull came into Mizuhara's mouth and she gulped it down and it went into the stomach where Ruka looked at it. She screamed and realized that the cum all over her used to be Sumi. Mami's balls were half the size they were still full of cum and she pulled her cock out of Mizuhara's mouth. Mami lifted Mizuhara and put her on the bed and lifted her legs.
 "I'm going to be taking your virginity now" said Mami with a giggle
 Mami pushed her giant dick against Mizuhara's pussy and then rammed it inside. Mizuhara screamed in pain and felt her insides shift around with each thrust. Mami moaned and laughed at the pathetic Mizuhara as she ruthlessly raped her. The acid became more hot and Ruka was being melted fast. She cried and called out to Kazuya as her body became mush. Being fucked added digestion and Mami put her hands on Mizuhara's belly. She pushed down several times while thrusting.
*slop..blurgle...crunch...snap*
Ruka was put to an end as her body was mangled and broken. The acid melted the body down and Mizuhara's belly rounded out with bones pressing in several places. The gut churned and gurgled and soon enough Ruka was pumped through Mizuhara's intestines. Her belly shrank as her breasts and thighs fattened up making Mami smile. She squeezed Mizuhara's tits making her moan. Only a pudge belly remained. Mami moaned as finally she came inside of Mizuhara pumping the last half of Sumi's cum form in her pussy. That made Mizuhara's belly grow again. Mami took her dick out and got her special panties on and her skirt back on. It looked as if no dick was there. Mami giggled and then stood back a little while pressing on Mizuhara's belly forcing cum to spew out. A puddle of cum was at the foot of Mami's bed and Mizuhara looked like she was out of it.
*flllwarrrppp*
Mizuhara farted and Mami smiled and dragged Mizuhara off the bed. Tears streamed down her face as she was forced to squat by Mami. Dark brown turds squeezed out of her ass and plopped in the cum on the ground. The wet shit had clumps of black hair and bones mixed in. Mami huffed the air, getting the smell of Ruka's form in her nostrils.
*splat...plop*
The pile of smelly wet shit grew higher and higher with bones sticking out. Ruka and Sumi's skulls popped out and were buried in the mudslide of scat. It took a full ten minutes of non stop shitting until Mizuhara's bowels were empty. When finally down, Mami pushed Mizuhara into her own scat and smiled at her.
 "Welcome to your new life as my sex toy" said Mami
 Mami left the room and locked the door. Mizuhara looked at the ceiling covered in her own feces and cried.
