Dr Pershing's first visit.

It had been child's play for Dr Pershing to synthesize more 'medicine' from his sperm, leaving him with several syringes worth that he was now prowling the dark, silent hospital with. He'd taken off his shoes and socks, prowling the deserted hallways on the soft pads growing at the balls of his feet, allowing him to move in near-perfect silence. And his first stop was the room of one Robin Norton, who, after taking a tumble on his farm with his ATV, had severed his spinal cord and was now paralysed from the waist down. Sneaking in, careful to not make a single sound, Dr Pershing pulled out one of the syringes he carried and emptied its contents into the drip attached to Robin Norton's arm. Then the heteromorph doctor left, as silent as he had arrived, off to find another patient in need of his unique treatment.

Robin awoke with a start - and an impressive boner. Which was strange and exhilarating for two reasons: the former because he had an erection at all, the latter because was able to feel the sensations. For the last two weeks, there had been no feeling below his belly button, no matter what the doctors tried, but now, Robin could feel everything. But the fact that he could move his legs again played second fiddle to the insistent throbbing in his loins - two weeks of no sex or even wanking made Robin a horny boy, and since the outlook the doctors had painted for him had been "not using his legs or dick ever again", Robin threw back first the covers and then his hospital gown for some celebratory masturbation. It was, after all, so late at night it was almost early in the morning, and Robin was lucky enough to be alone in his room.

His shaft was so swollen and erect that it looked almost purple, the mere touch of Robin's hand making him groan and throw back his head as he stroked his unnaturally sensitive rod. Waves of pleasure rolled over him with every languid thrust of Robin's hand, and soon, it became apparent that his turgid shaft wasn't the only source of lust on Robin's body anymore. Without his conscious input - higher thinking addled by arousal - Robin brought his left hand up to his pecs where they were hidden under his gown, his palm brushing against an impossibly erect but more importantly sensitive little nub.

"Mnnuooh~..." Robin's jaw went slack as he rubbed his left over the buzzing, throbbing nipple, arching his back in bliss as a first dollop of pre appeared on his glans. "Fuh-fuh--ugh!"

As Robin pumped his shaft and rubbed and squeezed his pec, the latter began to slowly swell, growing soft and pliant - and the former began to dwindle and shrink under his fingers. Robin barely processed, let alone minded this new development, as the sensitivity only rose with each inch he lost, with every bit of girth that disappeared. Deep, shuddering breaths washed over his lips, lips that were themselves plumping up with every passing second, but all Robin cared about was the small breasts inflating on his chest and the cock shrinking between his legs.

"Ahaaahnnh~..." Even Robin's voice was affected as he crooned and moaned, his deep bass turning into a softer, richer timbre that was undeniably feminine. "Oh my... gaawwd~..."

Writhing on the sheets, Robin took a second to pull off his gown, revealing the wobbling orbs expanding on his chest to the cool air. Already they overflowed Robin 's left hand as he groped and caressed them, and the perky mounds showed no sign of slowing their growth. The reverse was true for his twitching rod - it had shrunk so much that Robin barely had anything to tug on by now, but every touch on the dwindling nub made his widening hips roll and gasps of pleasure echo through the room. And finally, with already enormous boobs heaving on his chest, Robin found that he could only rub his palm against the tiny little dicklet pulling inside of him... and that his fingers brushed against a set of wet, swollen lips opening beneath it.

"Haaaaaah!" The sensation of her middle and ring finger penetrating her made Robin sit up straight with a rising gasp, disbelief and arousal warring in the sound. "Ah--ah! Oh fuck!"

Hips working against the movement of her fingers, Robin pinched and pulled her aching nipples, breasts settling high and heavy on her chest, drooping lower under their own weight as they kept swelling. Her ass, too, had begun to expand, much faster than any of Robin's other curves... and into a strange shape. Far from being two fat, jiggly globes, the skin on Robin's behind quickly darkened into a glossy black as it grew into an arachnoid abdomen, eight long, bladelike legs unfolding and raising Robin from the bed even as she kept fingering her sodden cunt, hefting her enormous, soft breasts.

Even her original legs were not spared, skin growing hard, black and glossy, segmented at the joints to allow movement as Robin spread them sideways, her feet diminishing into pointy tips that clicked against each other as Robin's pedipalp legs twitched with lust. Her body now drider-like, with the human half sexually super-charged, Robin intensified the movement of her fingers as they, too, grew chitinous from the middle of the biceps downwards, the spider morph's fingers long and thin with clawlike tips.

"Oh my gh... gh... gaaahahaaawwwd!"

Throwing back her head and howling in bliss, Robin's spider body crashed back down onto the bed, making the frame creak with the impact. Mewling and murmuring, the drider caressed her newfound curves, spreading her squelching pussy open as she rested on the curve of her arachnid abdomen, boobs rising proudly above her. Finally, there were words in her barely coherent babbling:

"I need... someone inside me."
