In a flash the 'mouth' had thrown itself up on two of its musculer arms as a shot struck it's center of mass, which would have hit Scar dead between the eyes!
Scar had only a glimps of what happened to the 'mouth' as she bolted behind the solid cover of a plywood car. It's flesh seemed to boil and expand in varius ways but it didn't seem incopasetated. She'd have to clear the house that the shot had been fired from. Come to think about it, it was the house that had been fireing at her when she first entered the area. Guess her grazing shot hadn't done the trick.
Peeking round the corner Scar saw the shimmer of fire as another shot glided over the 'mouth' who managed to drag itself behind cover. Takeing a chance Scar vaulted over the plywood car's hood and into the makeshift garage then into the house!
Once inside her eight arms got to work, each holding their guns to cover a direction, giving her a almost perfect 360 field of fire. Each trigger charging a full shot. Scar was ready, this was the real test of her bright idea, if she got hit now it would all be for nothing.
Slow steps lead her through the house's jumbled interior, more for cover and fun of gun-play then simulation. Rounding one corner she quickly turned her back and fired one of her new guns at the would-be-surprise attacker! Her eye on her back spotting him as he came out from cover and planting the laser dead on his nose!
His gun flew into the air in surprise as the shot also blinded him. Scar watched as the boy's nose broadened and flared turning black and leathery before jutting out with his jaw. It also seemed to swell larger, becoming cartoonishly big on his body. Sticking out of the right side of his head, just before the ear was a had, presumably Scar's grazing shot from earlier soon morphed into a black hoof as his ears extended further up his head and his short black hair grew into a long mane. His eyes grew black and shifted to the sides as the head as brown fur sprouted from his skin finished its shift into a horse's head atop the boys body.
"Horse gun eh?" Scar teases walking closer to her disarmed victim. "Looks like this little doozy replaces a body part with the horses equivalent?" She charged a shot and fired at the boys crotch with a smerk. The beam struck the tip of his his limp cock as he scooted backwards trying to get away. He let out a negh as his flaccid penis quickly shot to erect and beyond like a spring! Swelling and throbbing bigger and bigger. It's bell head blunting into the flat bloom of a horse's cock. The boys nostrils flared and his mouth panted between neghs before reaching to stroke his shaft.
But like a old western film another shot rang out from Scar striking him in the hand. His fingers quickly swelled into hard nubs of muscle, colliding with each other into a thick slab that resembled more of a paw then a hand. The fingers ultimately useless.
"Naughty-naughty!" Scar teased takeing aim at the other hand. "Tell me what your gun does and I'll let u keep your hand!"
The boy neghed and neghed, snorting and shaking his head and long mane.
"Hmm, looks like you can't answer. Guess I'll just test it myself?"
Scar had seen where the gun flew off too and had it in seconds. When she turned the boy had just gotten back on his feet, the thick cock almost bobbing his chin from its awkward curve and length.
Scar fired a full shot at the boy mid-stride! Toppling him to the floor. She watching with curiosity for the change. His first noticeable change was his normal hand, it swelled with thick muscles until it was a perfect copy of the other. Likewise the one hoof that sprouted from his cheek now had a matching twin on the other side of his face.
"That's what you get for shooting at me and my friends!" Scar boasted as the boy awkwardly stumbled back to his feet and out the house.
"Symmetry, that's certainly a different gun. Must have been hard for him to make any progress early in the game, guess he deserves some credit."
Back outside Scar confirmed her suspicions with the 'mouth'. It's body now sported three more musculer arms as well as a matching eye on its other side, the symmetry seemed to start from its large lips.
"Was that horse thing that just ran by your doing?" It asked?
"Not my best work, but then again, I wouldn't want you to think I'm replacing you!" Scar said with a wink before she was suddenly struck by a realization! "Oh my god, you took a bullet for me, literally! And I don't even know your name!"
"You can call me Tera, and it's alright. Fog of war and all that, but I gota say its pretty fun having you around, I'd be happy to tag along longer!"
"Glad to hear because.."
