Regina is the first victim

Regina and Sophia wriggled and squirmed against the rope restraints, eyes widening in terror as 2 huge, pink cocks burst through the transformed Mark's pants, tearing away the fabric covering his crotch as easily as tearing through paper. The tape muffled their yells of "Get away from me!" and "Stop!" as precum started to leak from both cocks, a surefire sign of horniness.

The girls tried to run (or more appropriately for their situation, hop) away, but their attempt at escape only resulted in them falling face first on the ground, groaning as their asses stuck up in the air, the round and succulent cheeks pushing against the tight skirts they wore as the more they struggled, the more their butts swayed to and fro in the air.

This sight acted as a siren's call to the lizard... Snake? Lizard-snake? Lizardman Mark, who's slit pupils eyed them up, desire present in those cold dark eyes. Encouraged by the seductive sight, he pounced on Regina, who let out a squeal of horror as the blonde was pinned under her transformed assistant, feeling the warmth and pulsing of both cocks on her bare exposed legs while her brunette other assistant could only squirm and watch helplessly.

Rolling Regina over on her back, the lizardman was oblivious to her muffled pleas of "Please, Mark! I know you're still in there somewhere! Stop!" as he tore the lab coat and skirt covering the goods, exposing Regina's plump bare ass and fat thighs.

Sophia clenched her eyes shut, knowing what would come next. The thin layer of black panties covering Regina's privates from the world was torn away in an instant, her stifled cries getting louder as the mindless lizardman plans to indulge in the most primal pleasure every animal seeks.

Unwilling to wait any further, as evidenced from the gooey leaking precum flowing down both cocks and connected to Regina's thighs by a thick string, the liazrdman placed both hands on her back, pressing her down as she struggled in vain, before roughly pushing both cocks into Regina's pussy.

Regina grit her teeth, fighting back the instinct to faint as her pussy gaped from the **** and size of both cocks combined, it's walls stretching to their limit as the brutish members are **** into her tight hole. She didn't expect her first time to be like this!

Sophia tried to block out Regina's moans and the animalistic panting of lizardman Mark. This is horrible, but this is her chance! With Mark distracted, she could slowly inch her way to a exit or phone, getting a chance to free herself and alert someone! It posed a risk, she admitted, of dire consequences if the lizardman notices her attempting to escape. Still, she should try!

With the lizardman pushing her boss down and ravaging her, Sophia started to shift her body away slowly.

Slowly, slowly, inch by inch... Her heart pounded fast with nervousness as she inched away from the scene towards a nearby door, metaphorical fingers tightly crossed that her transformed coworker would be too distracted to notice...
