She tests out draining her implants.

Samus looked down at herself. While her growth was slow, she was noticeably larger than when she had left the upgrade room. She figured now was as good a time as any to test out her nipple upgrade.

Searching through a pile of cables, she found one that looked almost made for her. It was thick, almost two inches in diameter, with one end capped by a plug designed to insert into the power box. The other end split into two cables, with each leading to a large cup. The cable looked eerily similar to milking equipment, which did nothing to diminish Samus's previous self-comparison to a cow.

She walked over to the power box and inserted the cable. A little green light lit up to affirm the plug was properly in and secure. Samus pulled her suit outwards and off her breasts, exposing what little of them had remained covered. She lifted up the cup ends and placed them over her hardened nipples. They clamped down, causing her to nearly orgasm from the sudden, hard nipple compression. Her mind swirled with a mix of fear and excitement. Would this be painful? Would it be pleasurable? How would it feel to have her breasts shrink? Would her stretched skin be fine?

She had to do this eventually, though, and it was better to first try it out sooner than later. She placed a finger on the activation switch, steadied herself, then flipped it on. The box hummed to life, and it immediately began sucking the stored energy out of her implants. Samus cried out in a long, loud moan. The feeling was intense, like both nipples were cumming as hard as possible. It was hard to describe. She could feel something coming out, but it was something without mass or substance.

Pulses of light ran through the cables as the power flowed through them and into the storage silos. Her breasts gradually deflated as the machine drained them. Samus could hardly notice, though, as she was too busy cumming her brains out to really think of anything else. Two seconds in she had collapsed to the floor, arching her back up as she squeezed and kneaded her tits. A puddle grew underneath her as she let out a constant stream of fluid. She writhed on the metal ground, moaning and screaming, almost unable to handle the sensation.

In only half a minute, her implants were emptied, and the machine came to a stop. Samus lay there for a while, just breathing, needing to rest after that. Her body sat in a puddle of her own feminine juices, but she couldn't spend the effort to care. She pulled the clamps off her nipples (almost cumming again) and checked out her tits. They were about the same size as when she had just installed the implants. At least she confirmed the process worked.

A little robot wheeled in, carrying a clear, large bottle of water. "I thought you might need this. It is important to your health that you stay hydrated, especially after expelling so much liquid," said the AI, rather bluntly. The robot wheeled up close to Samus, and she silently grabbed the bottle and started chugging, suddenly aware of how thirsty she was. She was also suddenly aware she could feel her boobs expand ever so slightly faster once the little robot got close, due to the electrical workings inside it.

"I can see the extraction upgrade was a success," continued the computer. "That is good. As long as you stay within short distance of a suitable machine, remaining mobile should not be an issue."

Samus wondered if she should even worry about that. If she was going to be stuck here, anyway, and the computer could clearly take care of her basic needs, why bother keeping herself mobile? It seemed like unnecessary work, plus she didn't know if she could handle experiencing intense orgasm every few hours or so. Not to mention, a part of herself wanted to see what being truly huge would be like.

A loud boom in the distance broke the peace, and the whole room slightly shook. Samus was immediately at attention. She knew trouble when she heard it.
