The infiltration

[The First One]

A fit but tiny assassin/spy covertly infiltrates a compound dedicated to making super soldiers, and to keep the compound used for it from the enemy takes it all herself, causing her to grow from about 4'10 to about 10-15 feet tall and bulging all over with muscles hard enough to be bulletproof.  She smashes her way out of the facility


The compound is powerful enough in small doses that it needs to be heavily diluted for the drinker to be small enough to function.

"Super soldiers?" The 4'9 brunette with the figure of a ballerina repeated.  "Yes," said her handler, "Doctor Cren is producing a drug that can permanently induce massive increases in size and strength with a single dose.  Intel suggests tissue density also increases enough to repel bullets.  We need you to infiltrate the doctor's compound and dispose of his work by any means necessary."

The facility wasn't as heavily guarded as many that Tanya had infiltrated, at least going by the intel she was given going in.  Probably due to the enemy not realizing anyone else knew about it yet.  Tanya was airdropped from a stealth jet into a forest about a mile and a half east of the compound, her fit body allowing her to run the rest of the way there without any trouble.  The small base was surrounded by an electric fence, but the building itself was tall enough for Tanya's grappling hook to carry her up over the fence to the roof.  Surveying the rest of the area through her binoculars, she could see that her handlers had been right.  A group of eight men were guarding the front gate.  The smallest was about seven feet tall and had to weigh at least half a ton of massive muscle, while the tallest beat him by six inches and was at least half again his weight.  All eight wore what must have been custom-made shirts and pants that hid pretty much nothing.  She licked her lips at the massive bulges straining their pants before she remembered why she was there.  She unscrewed a vent grate just below the roof, and slipped inside. 

The hallways were unsurprisingly wider than in most buildings, with higher ceilings.  Peering through the grates, Tanya could see normal-sized guards patrolling the complex.  Creeping through the vents, she eventually came upon her target.  A massive, vault-like metal door with what looked like a keycard system.  She kept searching, until she came across a bathroom.  She grinned as she saw a guard doing his business just below the grate she was looking through.  It would be almost too easy.  She pushed against the grate until it fell into the stall, and as the man-tall and muscular, but still clearly unenhanced-looked up at the disturbance, she firmly gripped his windpipe with both hands.  For the next minute or two, the guard vainly gasped for breath, before finally collapsing.  Tanya dropped into the floor in the stall, and found his keycard after a few seconds searching through his pockets.

The hall outside the lab was clear when Tanya got back.  Emerging from the vents, she scanned the stolen card, and the door slowly rumbled open.  The room inside was full of storage tanks that reached almost to the ceiling, connected by a network of pipes.  Where all the pipes merged, the single pipe into which they combined dangled down from the ceiling to a workstation, at which sat a man she recognized from the briefing.  Doctor Phineas Cren was a few inches taller than her and about her age, but skin and bones compared to her tightly muscular frame.  Before he knew what was happening, the agent had him in a headlock.  "Don't make a sound.  You do, and you die before anyone can get here to help.  I'm going to ask you some questions.  You're going to answer, and if I dislike your answers..." "Okay, okay, stop, please, I'll tell you everything!  Just let go!"  She did, and the doctor pressed a button at his workstation, closing the door behind her.  Tanya, pointing a handgun at him now, was surprised he didn't produce one of his own.  "If you sound an alarm, you die.  Got it?"  "Yes, yes.  Don't worry, I'm honestly kind of glad you're here."  "Why?" He blushed.  "Well, you've probably seen the effects of my serum already.  The truth is, I brought it to the army in hopes that they would let me test it on women.  I..." his blush deepened, "Women with great strength and big muscles have always excited me, but my superiors insisted on only using men.  If you get me out of here, I'm willing to defect.  I'll tell you people everything, I'll work for you, as long as I get a say in who gets it." 

At that point an alarm started ringing.  Tanya cursed.  Someone must have found the guard she killed on her way in.  "They must know you're here.  It's too late."  "Maybe not.  Is that," she gestured at the small beaker on the table Cren had been working at when she entered the room, "ready?"  "Almost."  "Almost?" "Even that small an amount has to be heavily diluted.  If you drank it as is, you'd grow too big to function in day-to-day society."  Tanya grinned.  "Well, there's something you should know about me; I always wanted to be as huge and strong as I could be.  Until now that wasn't very big by comparison, but..." Cren grinned back.  "I almost hoped you would say that." 

Without further ado, Tanya gulped down the serum.  She screamed as a searing burning spread throughout her body.  Amid the pain, she was peripherally aware of her catsuit tightening, then starting to rip, of her feet sliding across the floor as they expanded, of her hair growing down her back, of her voice growing louder and deeper, until finally the pain stopped. She had to bend her head down slightly to fit under the ceiling.  She was naked, and could feel her pussy dripping, and a clit longer and thicker than her legs used to be throbbing with arousal.  Her biceps had to be several feet around, bigger around than the massive chemical tanks, her pecs even bigger even though her breasts had melted away as she grew, and her legs were touching until she stood bow legged, which left her head still a hairs' breadth from the ceiling of the huge room.  "Damn," she rumbled, her voice much louder than before and far deeper than any man's voice she had ever heard, "How big am I?"  "Hard to say exactly," Cren, who now barely came up to her knee, replied, "But judging by the size of the room, over twenty feet tall, and half again as wide.  I'm not sure how much you weigh, but probably several tons at least."  Both of them stood there in silence for a moment before realizing they could hear the guards approaching.  "Wait here.  I'll come back for you when I'm done." 

The battle that followed when Tanya effortlessly tore through the doors was incredibly one-sided.  Tanya had become bulletproof, and even explosives and the male super soldiers were unable to even scratch her.  The hulking agent demolished most of the base, alternating between actively fighting the security forces and masturbating to her own power and size, still doing massive amounts of damage just from writhing in pleasure.  At one point she crushed a man in her vagina while using him as an improvised dildo.  By the time her assailants were all dead, the complex was destroyed, Cren having left as Tanya was working.  "Do you have some way we could contact my handlers?" The newly-grown giantess asked.  "I might need some practice to use any com equipment without breaking it now."
