There was only one lit light bulb, a table and a bottle of some kind on the table in the room. Jill eyed the bottle down the barrel of her gun as if it could come to life and attack her itself. In her experience, it didn't seem too far-fetched.
Jill scanned the room, not daring to set one foot in until she knew she was clear. There were no cameras in the room, and definitely no people. There was a strong chance that what lay on the table was the HC virus she'd been sent to retrieve, but this was too convenient to be anything but a trap. Still, Jill knew she had to hurry; the sooner she was out of the building, virus or no, the better. She slowly stepped into the room, and quickly felt the walls with her free hand for any hidden panels or objects. Once Jill was fairly sure she was alone and not being watched, she finally, carefully, made her way towards the object on the table.
It looked like a vial without a needle in some sort of case mechanism. Jill pulled out her knife and gingerly lifted the vial a little to make sure it wasn't booby-trapped. Nothing happened. Jill was satisfied for the time being; she needed to take this and hurry now. She pulled out small protective case she'd brought for this, and then grabbed the vial.
As soon as she did, however, the vial immediately blasted the room full with a white cloud of gas. Jill caught the brunt of it and started coughing frantically. Thinking quickly, Jill threw the still-hissing vial in the case, tucked it away and bolted out of the open door, wheezing and coughing the whole way out. She staggered down the stairs and towards the exit as she struggled to catch her breath.
By the time Jill opened the door outside, she was finally able to start catching her breath. She stopped for a second, coughed the last of the gas from her lungs, and continued back to where her bike had been stashed away.
"Valentine here, I think I got the sample but it's been compromised. I'm heading to the rendezvous now," she said into her earpiece.
"Understood. See you soon," her contact replied, and they closed the link.
Just as Jill was about a block away from where her motorcycle was, however, she felt a sudden tightness all over her body. She stopped and ducked into an alleyway, worried that maybe she was suffering an effect from the gas. Quickly ruffling through her pockets, Jill pulled out a can of herbal-spray, and sprayed it on herself while inhaling at the same time. This medicine had been designed to combat airborne agents as well as treat physical wounds.
"Ah...!" Jill gasped softly to herself, feeling a stinging sensation within her, namely around her glutes and chest area. She waited a bit after taking the medicine, but the feeling didn't abate. Jill winced as the feeling intensified a bit, then faded, but was replaced by a different kind of tightening sensation... Then Jill's eyes widened and her mouth was open in shock: she could see her breasts slowly filling her shirt out! They were growing!
"Damn it!" Jill cursed under her breath, now trying to run back to her motorbike as discreetly as possible. She needed to get away from this area and get help from the BSAA immediately. As she ran, she groaned inwardly as she realized her pants were tightening around her too, specifically in the seat! Was her ass growing too?!
While making her way back, just one street crossing away, Jill was forced to wait and hide for a bit as a few civilians walked by. While she waited, she looked down to see her breasts slowly pushing out against the fabric of her shirt, and starting to shove the holster straps across Jill's shirt out of the way. The beautiful BSAA agent had always been happy with her bust before, fairly large but not so much people would think her a bimbo, or so large as to get in the way during her missions. They had been a 40 D-cup size the last time she'd checked, but were now gradually making their way through the DD sizes now.
Jill grimaced and blushed in embarrassment, feeling her rear pushing her off against the concrete wall she rested against. She could faintly hear the stretching of fabric from her cargo pants now as her butt blew up behind her like a slowly-inflating balloon. Jill had always had a great ass from all the exercise she'd gotten since S.T.A.R.S and every organization she'd joined since then to fight Umbrella and others like them. Not to mention, it always seemed like whatever calories Jill didn't burn always seemed to cling onto her rear or her breasts. Now it seemed her ass was trying to reach the proportions one would expect to see on a stripper or pornstar.
Once it was clear, Jill jogged over to where her motorcycle was, felt a wave of relief, and mounted the bike and immediately took off towards the rendezvous point. She prayed the BSAA would be able to help, or at the very least begin to understand the HC virus, if that was in fact what she'd been infected with.
While on the bike, Jill could feel her butt filling out the seat beneath her, causing noticeable discomfort. The seat of Jill's panties was becoming too snug for her liking. Not to mention, her boobs were still expanding, filling out the space between her arms and stretching her shirt, bra and harness straps without mercy. As she drove, Jill tried to ignore the sensations until she could get to safety, but her bosom jiggled more and more easily as she went on, bouncing a little more for every little bump on the road. At one point she feared they may bounce so far they'd smack her in her own face. Her forearms brushed them a little more every time she turned, and her ass was getting too big for the seat on her bike.
After a few more minutes of driving, Jill was relieved to see the rendezvous point ahead. Her boobs were so big now they were starting to obscure the dashboard whenever she looked down, and she could feel her panties beginning to slip between her bulging butt cheeks. Jill parked her motorcycle as quick as she could, then awkwardly disembarked. She took a second now that she was away from danger, and peeked down her shirt to see her breasts more clearly.
The enlarged pillows of soft, womanly flesh were stretching the straps on her bra considerably, pouring out of the cups from the top, bottom and sides. Jill guessed they'd gone up to at least 38 DD cups from their starting 40 D size. She glanced around to make sure nobody would see her, and gingerly poked one of her breasts. Jill felt a white-hot surge of arousal shoot from her boob straight to her womanhood, and had to bite her lip to stifle a cry of pleasure. The feeling was so intense, Jill had rarely felt that kind of pleasure before, ever. If she'd squeezed and fondled them both a bit she very well may have came on the spot.
The creaking of her cargo pants brought Jill's attention to her derriere. When she craned her head around to look at it, her eyes widened at how much curvier, fuller and larger it had gotten since the short ride here. Even before growing, her backside had made itself known through bulky cargo pants, but these in particular were almost like khaki jeans with extra pockets. Her prominent posterior had filled what little of the pants' slack remained at its normal size, but now she could see the seams around the seat beginning to visibly strained as all the fabric stretched and stretched. Jill could see her wallet and other items stored in her back pockets in vivid detail, the fabric skin-tight across them and only getting tighter. Which was to say nothing of Jill's panties, which were riding up between her thicc cheeks rather uncomfortably now and were becoming tight all around her waist and hips.
Seeing all this made Jill pick her pace up into a jog. The sooner she could deal with her dilemma and see some friendly faces, the better. Thankfully, the rendezvous point was a safe area, good visibility all around, a small but sturdy temporary supply checkpoint and under BSAA surveillance 24/7, ready to have armed agents arrive within minutes. At least Jill didn't have to worry about pursuers for the time being. She decided to head under the roof of the checkpoint, a small temporary shack-like building made with light but bullet-proof material. Hopefully, her contact would be there waiting for her, or at least find other medical supplies that could help.
[What does Jill find in the building? Keep in mind she's still slowly expanding at the moment!]
