Stevie can't control it

Stevie locked eyes with the soldier while Brittany turned to walked away.

"Go ahead, Brittany, I'll catch up in a bit."

"Are you sure that's a good idea? I mean, it is pretty dangerous around here with all these sex crazed zombies that CAN'T CONTROL THEMSELVES.", said Brittany, trying to hint to Stevie.... but the words were lost.

Stevie's heavy DD breasts heaved against the flimsy sundress fabric, the milky flesh squeezing out between the overtaxed buttons. Her rock hard nipples began to rip the fabric. His eyes bulged at the sight....

Sliding her hand across the soldiers crotch she felt the bulge pressing against his zipper.

"My, your a big one."

Stevie looked at his name tag. "Private Johnson... how appropriate. "

Grabbing his hand, Stevie led him inside the abandoned store to a changing room. Somehow she kept her dual futa cocks and explosive muscle growth in check, for now. The virus wanted to spread subtly to preserve itself. Any outward show would get Stevie killed.

Everything in the Private's mind told him this was wrong. They had been briefed multiple times about the seductive nature of the infected. But this woman didn't have a cock sticking three feet from her body, so what would be the harm?

Stevie's mind fogged over in arousal, the virus took over her mind on a kind of autopilot. She unbuttoned her top to let the 20 pound mammaries free of their contstrait, but was cautious to keep her surprise concealed under the dress fokds.

Kneeling down in front of Johnson, Stevie undid his belt, button and zipper. Dropping his pants to the floor, his foot long election popped out and hit Stevie in the face.

With one fluid motion Stevie opened up her mouth and engulfed the fleshy monster inch by inch until her nose was pressing against his abs. Staring at the private's eyes, Stevie reached up and stuck a finger his anus, loosening it up for the next show.

The virus engaged the muscles in Stevie's throat and began to massage and suck the length of the member buried deep in her throat.

Stevie's dual cocks began to stir, inflating in diameter and inching out onto the carpet under the unsuspecting victim. She needed a place to stick both of them.

Her prehensile tongue slinked out from her mouth covered in mutagenic saliva. Flicking at Johnson's balls... it extended out reaching his taint. Forming a tip, Stevie's tongue pushed up into the skin and virus began to form a channel into his bowels.

Johnson started to leap back at foreign sensation but Stevie had a firm grip on his cock, he wasnt going anywhere.

Steve looked up again as the saliva forming Johnson's pussy raced thru his body. Breasts shot out from his chest and settled at DD cups to match Stevie's, shredding the uniform top. Blond hair cascaded down his shoulders and the pubic hair at Stevie's face disappeared. Johnson's body transformation was decidedly female, soft and round without the muscle mutation.

No longer needing to hide, Stevie's transformation rocketed out, her muscles shredding the sundress. Stevie's full amazon mass was on display, veins criss crossing her bulky mass of heaving flesh. Her dual cocks rose and struck Johnson in the ass and new pussy, penetrating easily. Her balls swing down between her legs, each the size of a bowling ball.

Still sucking on Johnson's cock, she felt the futa virus lengthen and broaden down into her own stomach.

Grabbing Johnson by the hips, Stevie easily stood, hoisting the transforming futa in mid air, her rippling quads barely straining. Cock firmly embedded in her throat and her own rods deep in the former male, Stevie bucked her hips up and down as precum dripped from the overtaxed orifices.

Coming simultaneously, the new futas sperm filled Stevie's stomach while Stevie filled the ass and pussy of Johnson.

The pair fell to the floor in a pool of white slime. Flashlights and voices echoed at the entrance of the stores. Johnson's company was looking for him. Johnson's cock inflated, smelling the male flesh approaching, in need of a place to plant more seed.
