Nier: XXX Super Explicit Stuffing Fantasy (Swipe to second picture for fuller tummy)

A2 had stumbled on this quirk in a data file that became unencrypted in a recent cyber attack. “2B has the ability consume limitless quantities of energy substances. It makes sense considering her capabilities, but what doesn’t make sense is the urge to exploit this newfound feature.” For weeks and weeks all A2 could think about was convincing B2 to find her maximum capacity... and maybe for herself to see how similar their designs might be.

The perfect opportunity had came. B2 was forced to retreat from an overwhelming defeat and was cursing the circumstances. “Damnit! How could I just get depleted like that with so much on the line!”

A2 surprised 2B. “I can help with that.”

“What are you doing here? I should... gah!” A2 struck 2B and she fell unconscious.

When she woke up she was in a lab of sorts, but it was different somehow.

“Ah, my rival is awake at last. How do you like my kitchen?”

“Why do you have me here?”

“Well, I stumbled onto a file that suggests your model has a limitless amount of potential for energy storage. Seeing as you’re depleted, I thought this might be a good time to test your abilities.”

“Why would I ever... what’s this?” 2B was constrained on a wooden chair and by a pair of chains keeping her hands raised over her head.

“Oh don’t worry, this is going to be fun. I thought we’d start with something less substantial. Have you ever had jello?” A2 pointed to a 3-door fridge that was absolutely filled to the brim with colorful cubes and fruit shapes. “Let’s begin.”

2B reluctantly gave in. It seemed like a good way to get her strength back. And if this ability was real, she could use her strength to escape the situation. The first gallon or so was easy, but 2B could start to feel her corset becoming more restrictive. Gallon after gallon continued adding to the pressure under her clothes. A2 noticed something was the matter.

“Are my test subject’s clothes getting uncomfortable? I would think so! After consuming 12 gallons. Let’s take a closer look” 2B’s belly was well confined in her corset, but her thighs were noticeably wider and spilled over close to the seams of her tights and some love handles were pushing out from below the corset. A2 poked and grabbed at the new bits of flesh that were rounding out all over 2B’s body. She felt a rush of excitement that was new to her. Was this arousal?

A2 couldn’t seem to figure out if she was envious of 2B’s quickly changing body. It was her turn to participate in the experiment. A2 walked over to the fridge and grabbed a few gallons for herself. The 2nd and 3rd gallon had put a lot of pressure on her insides and the excitement was still there. She rubbed her, now expanding, belly and could imagine it going further until she couldn’t see her feet anymore. But turning her attention to 2B, A2 felt it would be even more exciting going through this with an unwilling participant. “We’ve barely started.”

This time A2 set up a small pump at the end of a 20 gallon tank which was filled with more jello. Jello was perfect because it took up space in 2B’s stomach, but didn’t have enough calorie energy to activate any latent abilities. She calculated that the pump could force about 1 gallon per minute and then she would give 2B 1 minute to breath.

Within the first ten minutes, 2B’s corset was tearing at the seams and she was moaning with pain. A2 stopped the pump and went to inspect her plumping specimen. She patted 2B’s corset. It was hard as steel with all that tummy contained. She saw a string protruding and thought she would just pull it. With that tiny tug, the string reeled loose and the corset burst off of 2B and her gut lay on her lap. 2B breathed a sigh of relief as her aching stomach had room to breath.

A2 slapped 2B’s belly and felt another rush of arousal. She took a deep breath and planned to leave the pump's nozzle in her own mouth for 3 and half minutes. Her previous fantasy was coming true. She watched in real time as her toes began to fade below her growing stomach. She stood near 2B's belly and rubbed both of their stomachs while she felt the pulse of jello filling every crevice inside her once small frame. 

A2 turned off the pump and rested both her hands on her watermelon sized stomach. She was moaning too, but this wasn't a painful type of moaning. A2 took a closer look at 2B and realized that the jello was still metabolizing in other areas of her body. While 2B's belly was still tight and round, her hips and breasts had begun absorbing the overflow. 

A2 could see some of 2B's breasts starting to fall out of their support and she felt the desire to pull them out and play. If placed in a bread pan, each breast was large enough to easily look like a lump of warm, malleable dough. 2B blushed, "Can we... get back to the experiment so I can get out of here?"

"Of course darling." A2 refilled the tank and started the pump again. 

Over an hour had passed and 2B felt the chair give way below her with a loud crack. Her hips had been spilling over the edges of the seat for at least 30 minutes. She looked like an obese rag-doll with her gorged belly and heaving breasts drooped towards the floor while her hands were still restrained from the ceiling. 

A2 turned the pump off for one minute to take a measurement of how far 2B's belly was from the floor. “13 inches.”

A2 hadn't been eating jello nearly as fast as 2B, but her own body was filling out quite nicely. She adored her love handles and growing breasts. It was time for a decent filling of her own. 

A new recipe was in order. Half jello, half marshmallow fluff. It filled at the same rate as jello, but expanded upon entry. There were more calories than before, but her emotions out-weigher her worries about any of 2B's latent abilities being activated. 

A2 would try the new recipe for herself. Feeling a little envious of 2B's rag-doll position, A2 copied her by getting on her knees and resting her hands on the counter. Her breasts and belly swayed to and fro as she switched on the pump remotely. The familiar pulsation of liquid being forced into her stomach resumed and she felt a tingling between her thighs and she became wet from all the excitement. She didn't want to miss the moment IT happened. Second after second she waited for IT. Every pulse of the substance that went down her throat caused her to sweat. Finally she felt IT. The cool sensation of her expanding belly touching the cold, cement floor. With a few more pumps her belly occupied at least a 7 or 8 inch radius on the floor. 

With that satisfaction, she turned off the pump and got on her feet. A normal human might feel the need to rest, but androids had more durable frames to handle a load like this. Even with her higher strength, it was a weird sensation to feel this much heavier after just a few moments. She saw her reflection and flushed red with excitement. The marshmallow mixture had done a great job. Rather than its previous watermelon shape, her belly had more of a fatty shape to it. A second roll was starting to form above her belly button and her butt and thighs were starting to wrap around each-other. 

A2 turned her attention back to 2B who was still hanging from her, now strained, wrists. A2 almost gasped out loud. 2B's quirk must be way better implemented than her own. She was at least twice the size of A2 still. She was filled with almost as much excitement as she was with marshmallow goo. A2 strapped the nozzle back in to 2B and resumed feeding. 

The marshmallow substance had great effect. She could see on 2B's status monitor that her strength was returning, but the acquired weight seemed to be enough to keep her from activating her powers. 2B's belly was finally touching the floor. She moaned and quivered. 2B’s displeasure had a great effect of A2’s satisfaction. Seeing her immense subject at her current state forced A2 to put a hand down her own panties. Rubbing her belly and her clit at the same time, sensations pulsed through her body that reminded her of when she was hooked up to the pump. The tingling started in her toes and worked up her legs, thighs, and into her groin. Feeling her own plump body, still getting fatter thanks to the residual marshmallow in her stomach, sent her feelings over the top. She shook and moaned as she began her orgasm, never taking her eyes off that fat cow, 2B. The sensation in her groin worked into her stomach and her breasts tingled. The tingling turned into burning sensations as she squirted into her hand and screamed at her climax.

Just as things were getting good, 2B’s chains broke free. A2 was afraid her fun was over, but 2B could barely hold herself up because of her immense, stuffed stomach. A2 walked over to the struggling 2B and rested her belly on 2B's back, adding to the load. "Maybe I went too far sister. I'll take it easier on you tomorrow."
