As Rias summoned a magic circle everyone walked onto it. "Where are we heading this time?" Asia asked worried, "we are going to an old warehouse, with some strange magical energy in or near it." Rias responded, as the group appeared inside the warehouse fence. "What the?" "What's wrong?" "Hey?!" The group starts saying confused. "I can't use my magic?!" They all say. "Um Rias?!" Issei says confused, Rias responds "we must of teleported into a magical barrier.""Well, let's get inside before we're seen." Akeno says cheerfully.
As the Gremory house walked into the pitch black warehouse, through an open door. They heard several strange noises, as Asia then tripped on a plank of wood. Which flew into and knocked over the wood holding the door behind them open. The door quickly slammed shut with a loud *boom* Asia immediately started apologising, which led to Issei saying "hey it's alright Asia. It wasn't your fault." As this was going on Rias and Akeno were trying to use any sort of magic they could manifest. But sadly nothing came out of their fingers.
Rias then sternly said "shhh!" Everyone froze, as they listened. From the darkness, they heard what sounded like a "mmmooo." Issei whispered into Rias ear "was that a cow?" Rias responded with "I'm not sure?" She put her hands out in front of her and started slowly walking. It wasn't long before her hands made contact with something squishy. As she wrapped her fingers around it, a loud bovine "mmmooo.." came from in front of her.
Suddenly the lights flashed on, completely blinding the group for several seconds. As their eyes adjust, they saw Rias's fingers wrapped around a woman's breasts. As the group look at the woman they saw not two large breasts, but four large boobs hanging off her. Her breasts were bigger than Akeno's, they jiggled and bounced as she moved. She also had two long cow ears sticking out of her head, and above her ass a long thin cow tail.
Rias immediately let go and jumped back in shock! "What the...?!" Rias exclaimed. The group looked in shock, wondering what she was gonna do. Suddenly the woman looked in Asia's direction and licked its lips. Before Asia or anyone could react, the woman was on top of Asia forcing its nipples into Asia's mouth. Milk started rushing down her throat and dripping down her face. Issei and akeno pulled the woman off, as Koneko grabbed Asia. The group ran down the now lit up hallway, and ducked into the first open door they found.
Safe for now inside the room everyone looked at Asia with worried eyes. "What was she doing to you?" Issei asked, "I'm not quite sure but I feel hot." Asia responded softly. Rias puzzled what to do and what had just happened, drifted off into thought. Asia's face flushed as a heat started to build up inside her causing her to sweat profusely. Her breasts started to press into her bra as it constricted her unable to hold their growing size. Her breasts slowly started to expand more despite her's and her bra's protest as buttons started to fly off her shirt before a loud rip was heard and echoed across the room. Revealing her plain white bra for the world to see. Which soon snapped revealing her expanding breasts. Issei's eyes practically exploded from his head as she was almost knocked out by a nose bleed as Koneko quietly muttered "pervert' under her breath due to Issei's antics. Asia became dizzy for a moment as she leaned onto Issei for her support her ears having becoming long thick cow ears and a tail had snaked its way over her panties dancing around all the while. Her breasts became larger and larger all the while till it was clearly around the same size as Akeno's as she leaned a bit forward unused the new weight on her chest.
Rias spoke, "This must be some black magic, because I've never seen or heard of anything of this sort." "Maybe it's a failed or working cast from the fallen angels. They are always trying to get more sex slaves." Akeno said, "I don't think this is fallen angel type work." Rias said puzzled. Suddenly the doorknob start to twist. "Quickly hide!" Issei said.
Running for hiding spots in the large half darkened room they all watched the door, as three more cow women entered the room. These were different from the first. They had 3 sets of massive teardrop breasts and a cow udder hanging off their bodies, just below their stomachs. Rias and Issei squeezed themselves into a closet. Issei peered through the small window, as he felt Rias's breasts push up against him. As Issei peered out he notices Koneko was the unluckiest, with her hiding spot. Akeno across the room had found a shelf with paint cans on it. Koneko's only hiding spot was behind the door.
The cowgirls stopped in the middle of the room, and sniffed the air. As they scanned the room for anything, one spotted Koneko trying to quietly creep to cover. It licked its lips and gave a loud bovine "mmmooo!" The other cowgirls turned to it. They all looked at Koneko, as they then started to set upon her. Suddenly a loud bang echoed through the room. The cowgirls looked for the source, to find Akeno pinned to the ground by another cow. This one had even bigger breasts, and 4 sets of them. Her udder was also larger, as it touch the ground and pinned akeno's feet down. It had knocked over some empty paint cans which turned to be the source of the loud noise. The first cow that had mooed must have alerted several others outside the room, or it just wondered in. The three other cows completely forgot about koneko and started to set upon Akeno. "What are you doing to me?!" Akeno said desperately trying to break free from the grip of the one on top of her. When the other three got too akeno they started rip her clothes off. All the cowgirls licked their lips when they saw the size of Akeno's breasts.
Suddenly one was knocked the floor by Issei and Rias, giving Akeno enough of a distraction to get free from her captor's grips. Issei's dragon arm was not being affected completely by the barrier, giving him enough strength to knock one across the room. As the three started to run towards the door, a loud moo echoed through the room. The 3 devils looked back to see if the cowgirls were chasing them. Just as they looked ahead of them again Rias and Akeno ran straight into two massive walls of cleavages. They both sunk into the soft squishy crevasse made by the breasts, as Issei sunk into the crevasse made by the two cows standing next to each other. Rias and Akeno tried to get out but the cowgirls grabbed and pulled them deeper into their cleavages.
At the same time, a cowgirl was on top of Koneko, about to force milk down her throat. While Asia wasn't in a better situation as a the cowgirl was able to sniff her out and was slowly going to pin her to the wall. Issei was in boob heaven trapped in between the two cowgirls, that Rias and Akeno ran into. The two girls tried desperately to force their way out of the squishy flesh. Their cries for help were muffled by the tit flesh. The cowgirls Rias, Akeno, and Issei had run into had five pairs of massive milk dripping breasts. Suddenly the two girls were then pulled out of the giant cleavages by two more cows. They ripped Rias' clothes off, as they then started groping the two busty devils.
Rias and Akeno desperately tried to escape their captors grip, as their breasts were squeezed, pulled at, and attempted to be milked. Rias and Akeno were powerless without their magic, as the cows continued to assault them. The action of try to fight off their captors and do it without magic was exhausting. Rias just cry and pleaded for them to stop. "No harm will come to you, if you just let us go. ahhh!" Rias said. As Akeno whimpered in pain the cows continued to assault their victims.
Rias and Akeno's cries were cut off, as each of them had huge milk dripping nipples shoved into their mouths. Milk gushed out of the cowgirls tits as soon as they were in the girls mouths. The only sounds Rias and Akeno could make were moans and coughs, as their lungs strained for air. Soon the girls ran out of energy to fight off their attacker and fell into unconsciousness.
Suddenly issei's magical power spiked as his dragon arm shouted "EXPLOSION!" the explosive power threw the cowgirls off of Rias and Akeno's, naked, bruised, and unconscious bodies. Issei looked across the room for Asia and Koneko, as he called their names. The cows seemed unhurt from being thrown into the walls across the room, as they got up. With their massive breasts bouncing and jiggling with every movement. Issei quickly picked up Rias and Akeno and ran out of the room and down the hallway.
With his last bit of energy, he flew up the air events into another room, as he blocked the door with tables. He collapsed from exhaustion and fell into a deep slumber.
It wasn't long after Issei passed out when Rias and Akeno came too, from the distant sounds of the bovine moos. Their breasts felt like they were on fire, as Rias opened her eyes to see her naked breasts growing. "Wwwwhhaatt!" She exclaimed as she started to panic as a pain went up her body that made her go to her hands and knees as a result. In the position she was forced into she could only help but watch helplessly as her breasts started to expand. Her already large breasts was inching bigger and bigger. Her breasts was so sensitive as they continued their expansion. Her face frozen with horror as she watched her chest grow into insane sizes. Already she getting closer to Akeno's size if not even larger but it was hard tell due to the fact they were still growing. "W-w-why do they keep growing" Rias muttered to herself as her breasts was increasing to the point her nipples was starting to touch the ground causing a new sensation that was starting to set her on edge. Though sadly her nipples started to slowly expand as well as it started to dig more into the milk soaked ground setting her on over the edge as she let out a small moo that she quickly stopped as soon as she let it out she refused to give in. Her breasts gotten to the point that it was starting to press into the ground below. As she was pushed upward slightly by her now much larger breasts it was closing to the size where she could easily be measured at twice her old size. Though much to her dismay it showed no signs of stopping in fact if anything it started to speed up much to her horror. Her breasts expanded at a now increased rate giving her more than a eyeful of her prodigious cleavage she know sported. She soon started to feel something pressing against her panties as it started to snake it's way upward over them as it revealed a large cow tail tipped with the same scarlet as her hair. Her ears soon started to stretch out becoming longer and thicker till it was that of a cows. Her breasts also finally stopped their expansion her breasts was so large it was easily triple her old size her nipples was easily a inch or two long which pressed roughly into the ground causing her to almost let out yet another moo but she stopped herself quickly.
As Rias was becoming heated, Akeno wasn't any luckier. Akeno could only watch on helpless as she saw Rias's breasts expand to massive sizes she was easily three times as big as she once was. Though she had no room to really think as soon her own breasts started to grow as well. Though unlike Rias her growth was a bit different as her nipples started to expand growing larger and larger all the while becoming thicker in the process. Her nipples while once small and was slowly becoming more and more like something you would find on a udder of a cow. It got to the point Akeno was sure she could no longer say she had nipples rather she was clearly at the stage where she had teats. Turgid by the heat she was experiencing her nipples stood stiff easily a few inches long and half as thick clearly way to large and thick to be nipples. As they continued to plump up into larger cylinders like tiny cans as a white drop started to form at their tip. Before she started to let out a slow but steady stream of milk from them. In the process her breasts grew Her already large growing larger in the process her nipples tingling due to the sensations she was growing threw and she could swear she saw them let out more milk in a sudden burst but she couldn't be for sure Her naked chest with freedom to grow slowly grew to where she was at least twice her previous size. Though her nipples was clearly way larger than they once was measuring around three inches easily and thick and stiff just like you would find on a cow.
Rias and Akeno started to pant as they slowly began to move towards each other a look of need and want in their glazed eyes. "I…I…..I I Need to to do this Akeno!" Rias screamed as her hands grabbed one of Akenos massive nippes and massaged it between her fingers the milk that was let out from the nipple increasing into a much more rapid stream. At the same Akeno was lost in her lust and started to grope and play with Rias's massive breasts. Milk began to leak from her nipple as Akeno brought her mouth to it and started to suck it gently. They continued this motion for awhile both of them lost in the lust as it only grew stronger in them. The craving for milk started to become much more intense as the urge to drink milk suddenly became a intense need. That seemingly couldn't snap out of. Rias's face was slowly inching closer and closer to Akeno's large nipple when a loud moo snapped her out of it. In the window a cowgirl was watching making a beckoning motion as her other hand squeezed her nipple milk shooting out with a loud force Rias briefly wondered how strong the stream was if it was that loud. Though it mattered little as they both began to crawl towards the door their breasts dragging on the ground in the process As milk seeped from their nipples aiding the growing milk pool that was formed on the ground. Their nipples only became stiffer as they crawled as it was rubbed against the ground constantly in their movement towards the door.
Rias froze though something was wrong as she sat back down and looked around her mind not processing anything till she saw Issei lying unconscious on the ground. Her mind suddenly became clear as the fog lifted from her mind "AKENO STOP!" She yelled as Akeno continued her journey. More milk seemingly began to seep into the room making the pool that much larger. Rias looked down at her massive breasts they were three times her normal size and her nipples was clearly beginning to start looking like a teat as it reached a inch in length. With a will she tried to stand up using all of her energy to get to her feet. Her new massive breasts making her a bit unbalanced as she looked at Issei hoping that he wake up but to no avail. As her eyes suddenly darted back towards Akeno her eyes widened in shock.
Akeno having made it to the door opened it as her mouth started to suck on the breast of the cowgirl who was formerly at the window. Akeno's chest started to grow rapidly as her breasts grew larger and larger. Her nipples started to become larger again quickly becoming large enough that there was no way you could miss them. It was large and thick and started to droop slightly. Her nipples was so large it looked like she had part of a udder on her chest rather than breasts. Her breasts took into a massive teardrop shape though it started to be pushed up slightly as a second pair of breasts began to form. All the while her ears turned into that of a cows and a tail snaked its way over her panties as it started swish happily as her second pair of breasts grew ever larger becoming closer and closer to becoming as large as her top set of breasts. Akeno let out a seemingly pained moo not long after a pink mass was growing on her pushing into her panties which constricted it as it continued to expand her panties snapped lost in the pool of milk below. In its place a udder was revealed with long teats that looked about twice the size of her to Rias she let out a loud mooo as her eyes was cloud with a desire that Rias couldn't understand.
"Akeno! Snap out of it!" Rias said moving towards her grabbing her arm. Akeno stopped her drinking and looked at Rias. Rias sighed "thank goodness." when Akeno then grabbed one of Rias massive tits. Rias' entire body filled with pleasure as she broke out with deep moans. Akeno forced herself onto Rias slowly moving her milk dripping breasts up towards Rias face. "Akeno…. Please…. Stop…" Rias said trying to break free from her friend's grasp. Her last ditch effort to get away, Rias drove her knees upwards. Akeno mooed in pain as she was thrown backwards.
A magic circle spawned underneath Rias, as well as one under Issei. Akeno started to recover from the attack, as she let out a sluty moo. The room filled with dead silence as the magic circles disappeared, taking Issei and Rias' bartered bodies.
Three days passed before either of the young devils awoke. Having spent so much magical energy, the strain on their life force almost depleted. It was estimated that they would have died within twenty minutes.
Rias' eyes sprung open she quickly tried to jump to her feet, but she was unable to move. Instead, she found herself bound to the medical bed. Her now cow like ears twitched as footsteps came towards her from behind her. A friendly voice broke the silence, "Well it's good see you you awake, and haven't fully become one of those things!" Rias recognized the tone of speech immediately, as Grayfia.
"Where are the members of my house!" Rias says frantically trying to get up. "Issei is fine….. for the rest that went in they didn't make it out," Grayfia says in a tone of sadness. "Something you should know. Your house wasn't the only ones investigating strange magic. There were several, you and Issei are the only ones to come back." Grayfia says closing the door to Rias' room. Rias' eyelids felt heavy, as they tugged down with each passing second.
