In her furious attempts to get out, Ashley was soaking herself in Shelard's bile and inadvertently speeding up the already-quickened process. Shepard watched with a mix of guilt, intrigue, and something akin to pleasure as the gunnery chief began to lose her fight, her writhing inside slowing to lazy kicks that resulted in bulges from the outside, and then, eventually, nothing. The shape of Ashley Williams became much less a shape and more a formless blob in the belly of her superior. And even then, it didn't stay for long.
Before her very eyes, Shepard watched, and felt, as her uniform tightened around her body in different regions. Most notably, given their location in reference to her eyes, were her breasts, which had been modest to begin with but now sported a hefty set of knockers rivaling cantaloupes. Similarly, her thighs and ass began to pack on what was left of Ashley Williams that hadn't gone to the commander's forward batteries. After a minute or two, Shepard found that where there had been a massive gut the size of a person, there was hardly a bit of pudge to show for it on her belly. By comparison, however, Shepard decided she almost guaranteed needed a new uniform of more considerable size.
"Thanks, Ash," Shepard sighed, rising to her newfound height and managing to find balance where she really shouldn't have any, "At least you were worth something in the end."
The commander walked over to the door and opened it up, startling a crewman who happened to be walking past. She seemed startled by the pair of bra busters her commander didn't have just hours before.
"M-ma'am!" The crewman said, saluting.
"Carry on, private," Shepard dismissed, and went directly to her quarters, leaving the crewman gawking at the jiggling giant of a woman.
Locking her door, Shepard cupped a breast in each hand and gave them a squeeze. Real as real could be. Ashley was definitely there in every physical sense. If Shelard could do this now without hardly thinking about it... Was it worth doing again?
