She installs the suggested nipple upgrades.

"Alright, I'll install the nipple upgrades. That seems to be the best current solution," replied Samus.

"Please return to the upgrade chamber, then, so that I may provide it to you," request the AI.

Samus exited the examination room and returned through the path she previously took, noticing there was more bounce to her chest than last time. She gave her boobs a squeeze and moaned. They had to be fifty percent larger than when she first installed the implants, and their sensitivity had increased as well. Knowing her boobs were even bigger excited her, and she had to remind herself she was in a concerning predicament. This was not the time to get distracted.

As she entered the upgrade room, she could see that the chip was already ready for her to pick up. She quickly walked over to the terminal and picked it up. She quickly inserted it in her suit before she had time to even hesitate, not wanting to waste any time.

As soon as the suit registered the new upgrade, her nipples tingled. She gasped in pleasure as they elongated and thickened, pushing out of the sides of her split suit and stretching forward. Her breath quickened as they continued swelling, bigger and bigger. Her tits grew in tandem, likely from the transfer of energy from the upgrade to her suit. Spreading her legs apart, she stuck a hand into the crotch of her suit and began vigorously rubbing her pussy, unable to contain her arousal.

"Fuck yes, grow for me! Make my fat fake tits even fatter!"

Moving over to lean against the wall, she pinched one nipple as it grew between her fingers, moaning from the stimulation. It felt damn good. Her areolas, even as stretched as they were from her implants, puffed out as her nipples grew. That upgrade was really doing work.

What took half a minute felt like ten, and Samus climaxed as her growth finally halted, cum squirting through her suit and onto the floor. Panting and resting against the wall, Samus used the time to examine her new nipples. They were large, as long as her middle finger and as wide as two of them. They stuck straight out, utterly stiff and at attention. Around them, her pink areola had puffed up slightly, appearing like small cushions on her tits. "Nipples" seemed like an inadequate name, now. She had teats. Her tits were noticeably larger, as well, having grown to be twice as big as when she originally installed the implants.

She should have been embarrassed, even ashamed, but her balloons for tits combined with her large, stiff nipples made Samus feel incredibly sexy. Her boobs demanded attention, overshadowing the rest of her body with their size and stature. They were no longer just a part of her body, they defined her body.

"I hope that wasn't too much stimulation, Miss Aran," said the AI. "I should have warned you."

"I-it's okay," sighed Samus. She couldn't believe how she had acted. It was as if these upgrades had brought to surface interests that had been buried deep in her mind, under her pride and sense of duty. She looked ridiculous, yet it excited and aroused her to levels she had never felt.

She stroked one of her enlarged nipples, gasping slightly as small sparks of pleasure hit her. "Tell me, computer, how do I actually use this upgrade?"

"You will need a device designed to siphon energy from some kind of port or nozzle. There is a power transfer station in the facility, not to far from this room. There you should find some suitable equipment. While your current rate of expansion isn't high enough to warrant rushing, I urge you not to doddle, either."

Again lights turned on to lead her way, and Samus saw no reason not to follow them. As she walked, it was impossible for her not to notice how her tits bounced and swayed, her nipples dancing in the air like a conductor's baton. She subconsciously stuck her chest out to emphasize them as she strutted down the hall. She smiled, half in amusement, half it legitimate joy. With each step, her tits were slightly larger, almost imperceptibly so, but Samus could feel it. And, instead of fear or worry, she felt excitement and anticipation. Knowing that she could now drain them at any time, she almost wanted to see how big they could get.

After about ten minutes of walking, Samus entered the transfer station. It was a large room, almost like a warehouse, meant to fit large machinery. The architecture was plain and functional, almost all metal, with little in the way of decoration. On one wall were several large tanks, clearly meant for storing energy. The display monitor next to them indicated they were currently empty. Thick cords traveled between them and a power box. The box itself had no real display, but featured several switches and ports. Miscellaneous equipment lay scattered across the room, from cables of various types to portable power cells.

The AI chimed in, "if you would like, you can use that power box to transfer your stored energy to those tanks, though you currently do not have much to transfer. One of these cables should be compatible with your physical shape. I ask that you wait here while I devise a more permanent solution to your predicament. It will be safest here, where the risk of you growing too large is minimal."
