Fuck Frenzy

Swanson stared in horror as the intruders were beaten and armlocked into submission.

"Colonel... we don't know what the properties of this... WE HAVE TO GET OUT-"

Seconds later the test subject let loose an almighty howl and flung herself bodily into the observation room. Coated in her own cum and drool, she crashed into a heap of MPs and terrorists, writhing and clutching and pulling and licking and...

... with terrible rapidity, the irises of the MPs begin to redden. Their fending motions began to glaze over and their struggles lessened as their cocks hardened in their pants. One terrorist pulled himself away from the group and shuddered, looking around the room, his face contorted with lust.

Swanson screamed as he fled down the hallway. "IT'S JUMPED GENDERS! SOUND THE ALERT! Sound the... and then began to cough and slumped against the wall.

Back in the chamber, the young blonde Karen struggled out from underneath the goon trying to hold her back in time to see a gang of four men, some MPs, some her friends, furiously fucking the living daylights out of the redhead from the chamber. One was deep in her cunt, another ramming her arsehole incredibly hard, while another two pistoned in and out of her stretched mouth. Something about the whole scenario made her incredibly hot, tapped into some deeply-hidden part of her that had long fantasised about gangbangs and other forbidden sex. Lost for a moment in her thoughts, she barely noticed her former ally, his eyes bright red and his cock protruding from his fly, until he grabbed her roughly from behind.

"Derek! What the fuck are you OOOUUUMMPPPH!" she cried out as he suddenly shoved her mouth onto his massive erection. She began to struggle and even to bite, but within a couple of seconds her tear-filled eyes blinked once, then twice, then again to reveal a red sheen around her irises. Mere moments later she was on all fours, desperately shoving Derek's cock further and further down her throat, her mind filled with nothing but images of sex and cocks and gangfucks and spurting cum and thrashing bodies and sweat and cum and cocks and cum and fucking and...

In the far corner, Deirdre watched the unfolding scene in horror. More au fait with the dangerous possibilities of a viral outbreak than her friend, she beat her assailant's head against a nearby cupboard door and began to edge around the room. To one side her quiet, studious friend Derek began mouth-**** their leader Karen, and her movements gained an urgency born of desperation. Noting that all of the men in the room were occupied, she slid to the door and began to make her escape.

Unfortunately the corridor was already occupied. Dr Swanson stood facing away, frantically masturbating, calling out "AAAH... AAAAAAGGGHH!", his face contorted with horror at his own uncontrollable urges. Caught by surprise, Deirdre was in no position to stop and collided with him. He turned, caught sight of her, and the extra stimulation sent him wildly over the edge. His cum spurted forth in a torrent, catching Deirdre around the nose and eye.
