Mash meandered through the gleaming white halls of Chaldea, in her hand a few reports and a bit of paperwork she felt bad about giving. She knew how hard the person worked. Even if others thought she barely worked, but she knew better. She knew how hard the person worked. She looked at the papers with a weak scowl.
"I know this is important, but can't we have someone else do this? Senpai works so hard already. Just keeping the servants from going wild is hard enough for her. Mash sighed remorsefully, she hated having to give them more work. She soon reached the door of her senpai's room, she brushed some of her dark purple hair away from her eye before opening the door.
"Senpai, I'm sorry, I have more paperwork for you." the short girl called as the door began to slide up the frame. The moment there was a gap between the floor and door a woman's scream tore through the air. Mash's body shimmered golden as her short black dress, leggings and white hoody were all replaced with tight black and purple armour and a giant cross-shaped shield. A sword and purple cape fluttered at her hip as she readied for whatever was on the other side. She would have knocked the door down with a strike if she could, but that door was the most reinforced spot in the entire building, even a nuclear bomb wouldn't be able to scratch the room.
"Senpai! I'm coming in!" Mash cried, she watched the door slowly crawl up, a gap she could fit through slowly appearing. She wasted no time, charging at the wall opposite the door ricochetting off it to slide under the door. Mash's heels scrapped against the marble tile as she slid into the room. Her shield was ready for whatever threat awaited her, but what she saw was a shock even for her.

Inside the room, she had expected to find someone attacking her Master, or maybe a monster. But instead, she found her beloved senpai with a massive stomach, the woman's body had a large distinct bulge, that of a woman's body sliding down her throat, all topped with a pair of flailing olive-toned legs kicking wildly in the woman's mouth. Mash starred in awe, it was her senpai and master, Gudako Fujimaru, her short red ponytail fluttering as she tried to devour the thrashing legs, her beautiful golden eyes that Mash so often found herself lost in starring at the shielder in trembling fear. Mash's armour vanished with a golden shimmer. The shielder turned, quickly closing and locking the door behind her, it slammed shut far faster than it had opened, she knew no one could get in and only she and Da Vinci had the code to open it from the other side. Gudako watched in horror as Mash began to move over to her, the mage was too bloated to escape. Mash approached Gudako, taking the time to admire the woman she loved. Mash could hear a woman's screams coming from inside Gudako's bloated belly, the woman screamed for help. Judging by the voice it was Ishtar, the flailing legs also sported a green cattail which meant that the one in the mage's mouth was Atalante. Mash took the catgirl archer's thrashing legs in her hands, Atalanta said something, probably pleading for help, but Mash didn't care.
"There there, Senpai. If you aren't careful, you could get hurt," she smiled as she pushed the legs together so they couldn't resist. "Is that better? She shouldn't be able to escape now."
Gudako wasted no time slurping the slender legs down, now unable to fight back the famous greek huntress slipped down her master's throat with ease.
Mash admired the shapely bulge of the huntress as it slid into Gudako's large stomach, a smile crossing her face as she saw the form squish into the tight confines, Ishtar and her both struggling against the taut gut.
"Would you like a belly rub to help you digest them, Senpai?" Mash looked up at her much taller crush with a loving smile.
"I'd love one yeah." Gudako smiled back nervously. She'd expected Mash to freak out, to start screaming, be horrified at what had just happened. Anything but help her finish her meal and give her a belly rub. Mash wasted no time, her powerful soft hands began to massage the stomach of the woman she loved. She could hear the screams and pleas of the food, she wished they'd just stop whining. Didn't they understand what an amazing honour they had? They were so ungrateful. Mash massaged into the soft creamy flesh, she could feel the squirming bodies of the two women.

"I have to ask, how come you aren't freaked out? I thought for sure you'd be scared or appaled that I did something like this." Gudako looked down at her beautiful kohai rubbing the squirming belly.
"Why would I?" Mash looked up at her master with sweet gentle innocent eyes. She truly didn't see a problem with what Gudako had done. Ishtar's face sprung up against the tight flesh only for Mash to push her back into the gastric tomb with a smile.
"Because I'm effectively killing them, even if they resummon later, I'm still killing them," Gudako replied as she ran a hand through her kohai's hair.
"They should be proud to be your food. It doesn't matter why you ate them. If you want to eat them, then they should be proud to be your food. To keep you full, to make you stronger, that should be an honour for them, for any servant." Mash smiled lovingly. The shielder nestled her face against the squirming belly.
"Oh? Does that include you?" Gudako teased. Mash looked up to her senpai, her loving smile gleaming.
"Yes. If you wanted to eat me, I'd be proud to be your meal."
Gudako's jaw dropped hearing it, Mash leaned down to kiss the soft gurgling belly.
"Really? Well, that's good to know. I think I'll take you up on that offer." the mage chuckled. Her hands shot forward, pulling the shielder off the ground with a devilish grin. Mash let out a weak yelp as her tiny five-foot-two was hefted into the air so easily by her much taller master. Mash dangled in the air, looking directly into Gudako's golden eyes. Mash opened her mouth to speak only for Gudako's to clamp around her head. Mash let out a weak yelp of surprise. The world went dark, she could feel saliva trickle over her, Gudako's course tongue slowly dragged across the shielder's soft flesh. Mash let her body go limp.
"It's happening, Senpai is actually eating me." Mash's mind raced as the woman she loved savoured her. "Don't worry Senpai. I'm not going to try and escape, I won't hurt you. You just eat me up and enjoy digesting us." she whispered as Gudako's tongue tasted her further. Mash felt Gudako's lips pass over her soft neck. "I wonder what it'll be like to be Senpai's food? Will it be painful? Or will it be gentle?" Mash mused to herself. She didn't get to ponder the question for long as she found herself being spat back onto the cold marble floor. The bright lights of Gudako's room were blinding to the poor confused demi-servant.
"Why?" she whined, did she taste bad? Did Gudako change her mind?
"You taste great, but we don't want these two potentially ruining it for you do we?" Gudako tittered, pulling Mash off the floor with a grin. "After all, they're probably pretty mad that you reacted by giving me a massage rather than saving them. Besides, I still want a belly rub."
Mash nodded excitedly, without wasting a second, she sprung forward to rub the big belly. The next hour was spent massaging the bloated stomach, the struggles and cries of Gudako's food dying down eventually. Mash could feel their bodies breaking under her strong hands. All the while Mash's mind turned to what it would be like inside the mage's stomach. What it would feel like to be digested, to be churned away. Why would Gudako even eat her? It didn't matter, it wasn't food's place to ask that, but she couldn't help but wonder anyway. Maybe it was just because she was cute, maybe Gudako had thought about eating her for a long time now. Or maybe, it was just a sudden urge spurred on by what had happened. Maybe it was just some dark pleasure in ending her loyal kohai. To know that no one else was going to get to seduce her, to love her, or to eat her. Or maybe it was a dark desire to protect her, keep her safe as part of Gudako forever.
No matter the reason, Mash loved the idea of becoming part of her amazing senpai.
"Mash," the shielder shook her head absentmindedly. Gudako rubbed her kohai's head with a loving smile. "You've been a great kohai, and I'm feeling rather tired. So, why don't you relax? For being so helpful and giving me such a good massage, why don't you take a nap with me." Mash opened her mouth to speak, "Yes, you can use my stomach as a bed."
Mash squeed excitedly. She lept onto the large fat orb. She loved the way the stomach squished under her.

Mash's eyes fluttered open with a yawn. A faint gurgle reminded her of the situation she was in.
"Good to see you're awake, my cute snack." Gudako's voice cooed lovingly. "Now, I believe there was the matter of you for dessert?"
Mash nodded excitedly.
"Well then. Clothes off, don't want to miss all that cute kohai flavour. Though I do think that cute unitard will make you all the sweeter."
Mash nodded again, her body trembling with anticipation.
"I'll be right back." the shielder bolted up and out the room. She quickly returned, her clothes replaced with a tight black and purple leotard with an exposed cleavage and belly window, the leotard hugged every contour of the shielder's body. The mage could see the way her body quivered.
"You look delectable. Now come on," Gudako smiled, smacking her soft stomach invitingly. Mash bounded forward, landing on her crush's stomach. She had barely touched down on the creamy flesh before Gudako had her quivering body in her hands. She pulled her faithful kohai towards her with a smile, Mash's head rested against her master's soft breasts.
"Before I gobble you up. I just wanted to give you a little look at where you're going." the mage opened her mouth wider than any human should have been able to do. Mash gazed down the pulsing wet throat she had just an hour or two had her head in. Her heart pounded in her ears, a trickle of saliva running down her soft cheek. She panted at the touch of her beloved Master's hot breath on her face.
"Do it, Senpai. Enjoy me however you wish. No matter what you want to do to me. I'm yours." she moaned weakly. Gudako spun the helpless shielder around, her feet landing in her senpai's mouth.

Mash gasped weakly as they were soaked in saliva, the mage's tongue dragging across Mash's soft flesh, the tongue coiling around her ankle to pull her deeper.
"You're amazing, Senpai. I can't wait to be inside you, to be yours forever." Mash simpered gleefully. She watched in blissful agony as her beloved Gudako slowly swallowed her calves, it was the most amazing sight. She wanted Gudako to take her time, savour her as much as she desired, after all, food had no place to complain. But the trembling shielder would be lying if she said she didn't want to be tucked up tight in her senpai's stomach as fast as possible. Mash shook off the thought, all she could and should do was let Gudako enjoy her food. The mage crept further over the meaty calves, slowly working her way up to her prey's knees.
"I'm happy to sacrifice myself for you, Senpai. No matter how many gods we've met, I've only had one god I worship. You." the shielder blushed while reaching a hand out nervously to pet her devourer's head. She ran her fingers through the soft fluffy red hair. Gudako began to gently gnaw on her thighs as they fell into the mage's mouth.
"Ah, are you mashing me a bit before you swallow that part of me?" Mash tittered at her little joke, "Don't worry about hurting me, Senpai. I'm food. Bite as hard as you want, you can even bite my legs off. I don't mind, food should be happy to be enjoyed."
Gudako's bites didn't change as she chewed the creamy flesh so sweetly before.
"Ah! I'm not being annoying by talking so much am I?" Mash whimpered. How stupid could she be? No one would want to hear their food talking so much. "I'm so stupid."
Gudako shook her head gently, the shake sending Mash's hair tumbling around her. Gudako reached her hands up, one landed on her kohai's head for a loving head pat. The other stole her arms into its grasp, pulling the deceptively powerful limbs into her mouth, placing them just at Mash's crotch as she crested over the shaking girl's waist. The taste of Mash's leotard emanated saltiness from it. The salt only served to bring out the heavenly flavour of the quivering Mash all the more. Gudako could feel Mash's hands moving around in her tight throat. They were confined against Mash's hips, so there was only one place they could go. Mash's face turned red, her head bucking back suddenly with a gasp. Gudako just smiled around her cute feast.
"Sorry, Senpai. I just can't stop myself, please forgive me." she rasped, her hands frantically. Gudako would have laughed if she could, seeing Mash give into lust like this was so rare but that only made it all the more enjoyable. Mash wept frantically as Gudako moved further up her cute helpless meal. Gudako took the opportunity to chew Mash's pudgy stomach, a feature she had always considered to be one of Mash's hottest traits. Not fat, but not perfectly slim either, just a faint amount of pudge from Fou making sure mash "found" snacks a lot. It hid so deceptively under her clothes and armour, it looked so toned and flat, it was hard to spot, but it was there. Her pudgy belly slipped down the mage's throat, Mash let out a whimper of pleasure as her legs sunk into the soft boiling hot stomach.
"Senpai, I can feel your stomach, it wants me so bad. I wonder how long I'll -" she let out a scream of pleasure before resuming her quivering words "how long I'll last. Maybe an hour? A few minutes? I can't wait to find out."
Gudako moved past more of Mash, the shielder's hefty breasts, she wasted no time claiming the soft orbs as her prize. Kneading the mounds of boob meat to force them into her jaws. Mash whimpered and bucked at every bite and grope, every lick of her senpai's tongue sending waves shuddering across her helpless body. Mash bit into her lip to stifle the cries of pleasure she knew she'd howl if she didn't. Her pleading eyes gazing into the hungry golden eyes of her senpai. With a loud pop, her boobs shot into Gudako's mouth, her shoulders posed no issue for the ravenous mage. Wet slurping filled the room until all that remained of Mash was her head bobbing contently outside Gudako's mouth. The shielder's quivering eyes filled with lust and desire to be food for her goddess.

That's it, Senpai. One last swallow and I'm all yours, forever. Please finish me. Let me give everything I am to you." Mash pleaded. She felt the throat around her move as she braced for the final pull into the waiting stomach. To her shock, her body was pushed out of the hot gullet. Her breasts springing free of their tight confines, her limp legs being pulled from their soft warm home. Mash whimpered in confusion as she was pulled out of the stomach she so desired. Her sticky wet body slopped to the cold tiles.
"Why!?" Mash cried in confusion. What had she done wrong? Why had her goddess spat her out? She was so close, one more swallow was all it would have taken. Tears streamed down her face.
"Whatever I did to ruin your meal, I'm sorry, Senpai." Mash sobbed. Gudako shook off the daze of vomiting out such a large feast, once she regained herself she quickly wrapped her arms around her crying kohai. The mage pulled her slobbery servant into a loving kiss. Once Mash's cries had died down the mage pulled away with a smile.
"You didn't do anything wrong at all. You were probably the best thing I've ever eaten."
"Then why did you spit me out?! You could have been digesting me right now." Mash wept. Gudako placed a finger on Mash's trembling lips.
"Because then I couldn't eat you again. Plus, I'd lose my adorable waifu." She poked Mash's nose with a smile, "Losing you would be horrible. I wouldn't be able to kiss you, hug you," she hugged Mash tightly to accentuate her words, "Never see that cute smile again or hear you call me, Senpai. That would be hell. Besides, wasn't it you that said that Servants should be proud to be treated like food? To be savoured and enjoyed?"
Mash nodded weakly.
"And I loved every second of eating you. But the best part was how cute you were the whole time. You're so much fun to tease." Gudako chuckled, her warm arms still hugging Mash tight.
Mash sniffled weakly, "You're mean, Senpai." she flopped her moist head against Gudako's chest.
"I know. I don't intend on digesting you, ever. But I'd love to gobble you up again sometime. We can talk to some of the casters, see about finding a way so you can cuddle up in my stomach like the cute candy you are without dying. Maybe a teleport spell or something that stops digestion. Then you can spend as much time in my belly as you like." Gudako playfully pulled Mash's head against her fat stomach, a bright blush returning to Mash's lustful face as she instinctively pawed at the belly without thinking.
"You promise?" she whimpered weakly, her lustful eyes staring up at Gudako. The mage licked Mash's face teasingly "I promise. But I'd never digest you. You're my cute little waifood. First, though, why don't we help you calm down. I think I broke you by making you so horny, so let's take care of that." Gudako scooped up the panting Mash in her arms with an evil smile.
"Yes, Senpai. Please use me however you want. I love you." the shielder panted excitedly.
"Da Vinci's going to kill me if she sees what I did to you." Gudako laughed as she carried her dazed lover to her room for some "relaxation".

Got this idea and Mash wouldn't let it go until she was in a stomach or three (so expect more prey mash in the near future)
Here she comes across her dear master (who I am forever bumping up to 6,2 because the cannon heights are tiny!) who's in the process of slurping down a pair of archers. Mash is all to happy to give her cute bloated master a belly rub while offering to be desert
