The rat in the labcoat carefully applied his goggles, covering up his cobalt eyes. He turned towards his test subject, smiling toothily. "Thank you again for applying to volunteer in my fertility experiments."

Circ was strapped in place, standing. Each of the brown housecat's toned arms was held snugly by restraints that came down on rigid rods from the ceiling, padded with black silicone. Similar cuffs were on his ankles, and a metallic ring attached to the platform behind him held his waist in place. Despite the rigid system in place, it was surprisingly comfortable, even if it kept his shirt taut across his defined chest. However, a strange ring was held in place by several poles, placed right at groin level, wires and cables wrapping around the support rods to unseen machinery elsewhere in the lab.

In addition to his light brown fur, his hair was fairly messy and a shade darker, matching the goatee tuft of fluff on his chin. "Sure doc... what does... uh... this experiment do?" The cat asked, looking between the various banks of electronics and the scientist still grinning at him.

"Why, I'm glad you asked!" The Doctor walked over to a whiteboard that was placed near a wall. He rolled the whole thing out directly in front of his test subject and suddenly flipped it over, taking the feline's view from a number of incomprehensible calculations to a very simple diagram. A crude figure, not much more than a stick figure, really, was shown in the restraints that Circ stood in at that very moment. There was a large arrow pointing from that image to the same figure, but with one major difference. A slightly better drawn image of an immense phallus and enormous balls had been superimposed over where the ring had been in the previous diagram. "With this device, I intend to increase your fertility and reproductive mass one hundred-fold, at the very least."

As just what he was looking at hit him, Circ grinned. "Then let's fucking go!" The cat jittered in place, confusion replaced with excitement... he was already tenting out his jeans.

"Ah, so we should get started!" The rat snicker-squeaked, wheeling the whiteboard away. He walked to the far side of the lab, a good fifteen feet away. There was a half-wall with a viewing window in it nearby, and a panel with three old fashioned blade switches. Grasping the handle of the first, the Doctor turned to look at the cat. "Systems engage." He threw the switch. From various devices around the room, the tall antennae rising out of them abruptly sparked, the bolt of St. Elmo's Fire dancing up until the angle of the electrodes made the current lose contact, instantly resuming back at the bottom of the array.

Circ fidgeted a little bit... he could feel his fur starting to stand up as the devices charged the air around him.

"Capacitors charging..." The labcoat bedecked rodent threw the second of the three switches. Large wooden disks with inset metal electrodes in them began to spin with no sign of a motor, electric charges jumping between the inset paddles and the base as they sped up into a blur. The Doctor set his gloved paw on the third blade switch, looking to the cat. He held there for a long moment as the tension built. "And release charge!" He threw the switch and immediately dove behind the half-wall. His goggle-bedecked visage appeared in the glass window a mere moment later.

The cat had no chance to worry about this reaction. An intensely pleasurable tingle surged within his groin, from his pelvic floor to where his maleness was straining his underwear and fly. The tented fabric visibly went under more strain, before the teeth of his fly's zipper failed. An ample mass of a bulge pushed the denim apart, still restrained by the taut material of Circ's underwear. He looked down, panting... that was his cock at full erection.... Plus some orbs far more ample than he was used to.

Fabric creaked and snapped, sending the brown-furred scrotum jostling forward and his pink shaft unfurling. The cat's assessment had been incorrect. It was nowhere near erect, and in fact had been bent over itself. Circ stared as his loins continued to swell and expand, his eyes noticeably going hazy as pleasure overtook his thoughts. His chest heaved against his shirt as his excited grin turned into a dreamier smile, muscles in his face relaxing. "Oh, Doc... this is... aunghnnngh...."

Still not at full erection, the shaft pushed outward foot by foot, its weight fighting its stiffness as it sought to rise up from leaning against the cat's fat balls. Said testes suddenly draped down onto the small platform that the largest of the supports for the ring at his groin was protruding from. The stretching scrotum was resting on the underside of that ring, in fact, while the top of his pink, throbbing maleness pressed against the inside of it there. It already had grown beyond hope of touching fingers together using both hands to grasp the rod, and yet it kept going.

Over the hum and constant zapping sounds of all the electronics working, a wet churning sound filled the laboratory. The origin was obvious as the housecat's testes continued to swell to yoga-ball scale. At the same time, slick clear pre began to constantly trickle from the tip of the finally horizontal rod, sending the fragrant fluid splashing down nearly three feet in front of his nuts. As the penis' girth increased, the tension with the ring did as well, causing Circ to squirm, tugging at his bonds. It was hard to tell if it was out of discomfort or an intense desire to touch himself, however.

Then, the brown-furred sac contracted so suddenly it caused a vibration in the floor felt all the way behind the protective barrier. Circ's eyes rolled back into his head as the underside of his shaft swelled, the channel there inflating with the sheer pressure of his oncoming release. The ring sharply snapped off of the giant equipment, clattering as broken shards all around as the first shot lanced forth from the cat.

The Doctor let out a squeak as the shot struck the switch panel, denting the metal and splattering out, getting some on his labcoat. The next shot went wide with the massive cock's bucking, striking the barrier hard enough to crack the bulletproof glass. The rat ducked back further into the corner as the barrage of semen continued, the sounds of metal casings getting crushed and impaled with high pressure seed filling the lab.

And at the center of it all, Circ had the biggest shit-eating grin on his face, oblivious to the destruction his new maleness wrought upon his benefactor's research.
