Samus walked awkwardly down the hallway of her ship, her massively inflated body straining at her as her ship began to take off.  In her… Condition, she wouldn't be able to fit in her cockpit, which meant no cryostasis for her, meaning she'd have to wait this trip out the long way. She had managed to take off by voice commands after she got out of the cargo hold, and even getting in through that was a trial, exhausted by her voyage back to her ship. After a quick examination in her medical bay, it looked like her body would return to normal without complications, although it would take some time.

Samus sighed softly as she looked down at her enormously gravid belly, looking like she was carrying a whole family inside her as breasts to match lay upon it. Beside that were her massive hips, and her enormous spherical rear, complete with matching thighs, something she was actually grateful for. Despite the added difficulty in moving, without the added bottom mass, she would have toppled over long ago, and would only have gotten bigger from there. Her zero suit had amazingly managed to keep her completely covered, but it had been stretched to its breaking point, with any more growth spelling doom for it. Seeing herself in the shiny finish of her walls, she admitted that she looked more like a highly fertile mother than a hardened bounty hunter.

She reached her destination, a monitor on a wall giving a view from her cockpit, something that she'd need to be able to see out of her ship. She gave a look over the lonely space station, wondering just what plan had been set in motion there, considering it was marked "HUNTER". After a moment of seeing it,  Samus began to turn away, only to be hit by a massive shockwave of force, almost falling over as her ship rocked. She turned back around to the monitor, and found that all that remained of the station was debris, it having exploded, destroying all evidence and contents.
Opening the door to her room, Samus wished she hadn't been so completely disabled. Her scanner hadn't had enough information to go on with the Metroids that attacked her, or how they managed to do this to her. She moved over to her large bed, giving an appreciative sigh as she lay back on her soft bed, her first respite in her new body. With all the Metroids on the station being destroyed, it also removed any chance of her going back to retrieve one in several weeks, once her body had successfully returned to normal.
Still, she thought, as she sank deeper into her mattress, once she could fit into her suit, she could go out, find some answers, and… Her thoughts trailed off as a familiar feeling of pleasure an paralysis came over her, and her belly began to swell even larger. A screeing sound came from the lone Metroid that had managed to sneak onto her ship, attacking her as she rested.

With her belly growing from triplets at full term, to holding at least quintuplets in scale, the strain on her zero suit was just too much, and it tore completely,  everything from her breasts to her hips just tearing off, leaving, apart from a few shreds of fabric, only her gloves and thigh coverings intact, now looking more like stockings and opera gloves.

Samus's first thought was to panic, although she knew it was harmless once it had inflated her. Her professional mind knew that she now had a specimen to study once she captured it, and went to get off her bed. Except, as she found, she couldn't. Try as she might, the weight of her belly was just too much for her to hold, and she was reduced to lying back, flailing her arms in a poor attempt to catch the Metroid.

"I'm never going to catch you, am I?" Samus sighed at the Metroid. It was fairly humiliating for her, really. She was mostly naked, looking heavily pregnant, amongst other things, and couldn't even leave her bed.
"Well," Samus said aloud to her new companion, floating around her ship, hopefully to be caught by the automated defenses. "I guess I'll just wait then." Exhausted by her trip, her body, and all that it had taken, Samus let herself forget everything, and fell asleep.
