Sinful Desires

"So I guess we get to work now" reply's Carl walking over to Amanda. Jenifer walks over to Greg "so weres the infected?" Jenifer asks . Greg just stares through the slot "she's.....she's beautiful" he mutters to himself. "Whatever I guess" reply's Jenifer.

She then walks over to Carl and Amanda.

"So this is a DNA sample from zero" says Carl. "Yes.....but it's strange .....when compared to ours...it's very simaler, but hers is slot more.....how to put it.....reseliant then ours" reply's Amanda.

"What's wrong with Greg?" Jenifer asks.

"What you mean he's fine" answers Amanda, not lifting from the microscope.

"Are you sure...he want stop staring through the slot in that door" responds Jenifer.

Amanda just ignores her, as she continues watch these cells from paciant zero, rapidly multiply. Carl watch's as Jenifer goes back over to Greg. As she gets their, she hears a raspy, yet arousing Voice. "Mmmm....open it....then I'll sasshow you a real fuck."

"Of course...give me sex" says Greg.

Confused about what she just heard, Jenifer says loudly "um...he's opening the door now" Amanda jumps out of her chair

"GREG DON'T" she yells, buts it's to late.

Greg unlatches the lock. Jenifer, still looking towards Amanda, hears the door seek open.

The door opens, and out steps this beautiful , crimson skin woman. Who had horns, a tail , and wings with yellow slited eyes.

"Hehehehahaha" laughs Carl , seeing this creature. Amanda turns to him "Carl "

she responds. "Hehehe...and here I thought I was the only one" reply's Carl, shifting forms. His body becomes more muscular, as his skin turns Crimson. His clothes disappears, revealing a massive red cock.

While wings sprout along with a tail.

Horns follow with slited eyes, an onyx lips and claws, much like the females.

Jenifer sees this "what the.....Carl...h....how"

Jenifer mutters in shock .

"Shit it's already spreading" states Amanda, backing towards the exit door.

"Carl sees his sister just standing their.

"Mmmm.....I kinda did want to fuck you sssis" he hisses , stroking his massive shaft. Meanwhile, as promised, the female one has ripped off Greg's pants , and her plump onyx lips slide over his erection.
