The Brit who'd been blushing at Melissa was the first to show some gumption and move towards the rack of weapons. "Alright, looks like Lieutenant Wellbury gets first dibs!" Johnson shouted, quite pleased, as the dark-haired woman quickly grabbed up a whole slew of armaments. A semi-auto sidearm, a magnum revolver, a knife, a shotgun, an assault rifle, even a grenade, all quickly shouldered or stuffed into a holster or pocket somewhere on her uniform. She took care to pull some ballistic glasses over her eyes before grabbing a magazine, loading it into the rifle, taking aim, and positively spraying down Melissa at the other end of the range.
It did about as much as the sidearm - absolutely nothing, bullets being left at her feet without so much as a dent. Undeterred, Wellbury loaded another magazine, this time firing it off as she marched in close to the sergeant. Again, the bullets did nothing, leaving Melissa feeling rather cocky as the gun clicked... which she regretted immediately, as the rifle's butt came swinging across her jaw. It didn't break anything, but it sure as hell hurt, not to mention it threw her off her guard - and that wasn't something that the Brit seemed to have any intent of letting go to waste.
With a bellowing yell she threw the rifle aside, taking out the pistol and emptying the magazine into Melissa's chest as fast as she could manage. It did little harm, but the jiggle effect was noticeable - almost so distracting that Wellbury nearly didn't have time to grab the revolver next, slamming it into Melissa's mouth and sending six high powered cartridges into the woman's throat. The interior latex coating again prevented any harm from occurring, but she couldn't help but notice... the screaming lieutenant's face was flush red with arousal. It didn't take a genius to figure out that she was getting off on this.
That much probably became even more apparent as she used the full force of her body to slam Melissa into the ground, quickly straddling her as she pulled the shotgun off her back. Exactly what she planned to do became instantly apparent as Melissa felt the muzzle slamming deep within her pussy, the black latex quickly wrapping around it and forming an airtight seal. Thus, when she started firing off shell after shell inside Melissa... oh God. Suddenly she was screaming in her own fits arousal, as it felt like she was getting rammed with a force that should have killed her. Instead, the buckshot and sheer pressure of repeated discharges had her writhing in arousal. Within a couple of shells she was convulsing in orgasm; by the time the magazine was finished, she was completely lost in ecstacy.
Wellbury, of course, had one final play. Ripping the shotgun away from the sticky black entrance, she grabbed her grenade, pulled the pin, and kept the lever tightly held down until she was able to stuff it deep inside the sergeat, yanking her hand out quickly so that the latex could completely seal up. She was able to enjoy a few moments of the ribbed surface pressing against her insides before the detonation, and with it, the feeling that her very mind was being blow to bits. She screamed, completely surrendured to this rough, orgasmic joy, the evidence of her excitement coming in the form of fluids squirting out from her that seemed to be a mix of her natural fluids and a liquid, runny form of the latex.
"Now THAT is what I call endurance testing!" Johnson cheerfully commented, turning her attention back towards the other two soldiers. "Now, how about y'all ladies go'n grab some of those fire and melee weapons, and we take a look at how... she..."
The doctor trailed off, looking back awkwardly alongside the other solders as they realized that Melissa and Wellbury were still going at it. The lieutenant had ripped her pants down, stuffing her bare, soaking wet pussy into the sergeant's face. "EAT IT! EAT IT, YOU RUBBERY INHUMAN CUNT!" she screeched, the very proper and upper class accent clashing wildly with her crude, almost caveman-like bellowing. Difficult glances were shared as the trio pondered exactly what they should do... because as much as this was very much not a proper use of military time and resources, they were all enjoying the show.
