Butterfly

By William W. Kelso

Bianca felt the odd feelings return, stronger than before, as she bent over the sink and retched. Ever since she'd spilled that experimental formula in her lap; one that was supposed to extend the life span of rare exotic insects, a debilitating combination of nausea and pleasure had been growing steadily. Pain starting to well in her skull and joints made the blonde grip her temples with both hands as short stubby antennae pushed out from the perfectly tanned skin of her forehead. Her eyes caught sight of this for nary a second before she collapsed onto the tiled floor of the lab's bathroom as a mixture of overwhelming agony and orgasmic pleasure suddenly racked her whole body.

She lay gasping on the floor, writhing feebly, as she became aware of a throbbing pressure building within her sex as her vagina slowly began to dilate; the horrible feeling sickeningly pleasurable, as something began to irresistibly push its way out, forcing her to helplessly spread her legs wide and watch in horror the impossible transformation of her body. Her vagina stretched impossibly as a throbbing abdomen began to slide out in a horrible parody of birth, her vaginal lips fusing with it in the process as agonizing pain and sickening pleasure wracked her body as she orgasmed repeatedly with moans of near delirium. Her legs cracked and altered as did her arms as more joints began forming, and her pain was so great she barely even noticed the second set of limbs pushing from her sides as her screams echoed in the bathroom. With a crackling sound her skin began to tighten around her body as it became hard and shiny...chitin. Crying out for help she found her words garbled as a lengthening tongue slipped down over her hardening breasts and lapped at the moist bathroom floor as she slobbered helplessly, staring at the flopping organ in confusion.

Next her vision faded before exploding into a myriad of kaleidoscope like images as her eyes began to fracture into multi-facets as they became the compound eyes of the insect she was becoming, and as if peering through a fractured mirror she was forced to witness not only her humanity disappearing but her femininity as well as she felt a sudden surge of pleasure and something alien slid from the tip of her now long and alien abdomen, the strange organ slick and wet, throbbing in need. As her nose faded into her changing hardening face she inadvertently brushed her long proboscis-like tongue; as it flailed wildly, against the newly developed male organ protruding from the tip of her pulsating abdomen as it continued to swell. A long moan passed her lips as she found herself holding damp wavy hair aside with her now hard and two clawed 'hand' so she could lick her new alien sex some more, her other changing hand gripping her abdomen to help curl it closer as she shifted for better positioning; her strange new 'legs' skittering on the floor from the pleasure as she bent over, shuddering from the pleasure as she pleasured herself with fellatio. As she moaned in pleasure she failed to notice the changes increasing and speeding up, fueled by her sexual pleasure, not realizing the horrible mistake she was making. Had she resisted her new strange sexual arousal there might have been enough left of her in the morning for her colleagues to realize what had happened, but as her sexual pleasure grew her body began shrinking as wings unfurled and dried on her back, fluttering weakly. But soon all the woman cared about was self pleasure as the pain became something...distant as the change continued to speed up, the intense growing pleasure numbing it as her transformation into an insect rapidly continued. Pulling her lips closer she took in her new strange male member greedily, eagerly sucking and teasing it, wrapping her prehensile proboscis/tongue around it as her concerns faded in a daze of sexual euphoria. Ohhh, it felt so good! She had never experienced such pleasure, and all thoughts of trying to get help faded, but it was far too late for that anyway. There was no going back now, and she could feel her human awareness and memories flickering as new needs and instincts began to flood her mind as her brain became smaller and began to change, but she kept licking and sucking her new sexual organ, her body quivering in ecstasy. She now knew what she was doing was wrong, but couldn't stop as she felt the pleasure building towards a crescendo.

Bobbing her head up and down as she pleasured herself she failed to notice her hair becoming black even as it shortened and became more of a bristly fuzz and spread across her back, her hard shelled body now shiny black with red and gold markings and she was barely three feet tall now, and completely alien looking with little human remaining. Her once full firm breast had shrunk to mere bumps on her thorax, no nipples remaining. Her extra pair of limbs continued to develop; helping her to hold her even larger abdomen in place now as her head rose and fell with slurping sounds, and her arms and legs finished changing into those of a true insect's as her arms became legs as well, hard and shiny, multi-segmented, ending in strange claw like digits. She now had six legs, looking like a vaguely humanoid blend of woman and butterfly, and still she orally pleasured herself, desperate to reach the release she needed so very badly, to cum, even as her mind screamed in terror, her lust agonizing, eyelids and lashes fading from her facial features as she lost more mass, her head changing shape, her mouth changing as palps formed at the corners, her proboscis continuing to lengthen as her antennae became much longer and more feathery, waving back and forth.

"I'm...oh god NO, i'm..i'm...cumming....uggghhh, ugh, ugh, oohhh, aaaHHHUUGGHHH!" where her last human words as her mouth became totally that of an insect, lips forming into a wet round orifice; incapable of speech, now merely a tube from which her proboscis emerged as she kept licking her male organ as it explosively ejaculated, thick gooey cum spurting over her face. Feeling her spine finally dissolve as she orgasmed she fell forward onto to her six legs and pushed her abdomen out behind her shuddering body as her neck sank into her new thorax, her mind silently screaming as she experienced her...his first male orgasm. Hips popped and collapsed as Bianca licked his long tube like proboscis over his face and head cleaning away; and eating, the sweet sticky cum as his palps cleaned his proboscis, the massive ejaculation and ingestion of his own sexual fluids fueling the changes even further as they underwent a new burst of speed. His wings fluttered as thoughts grew dimmer, more distant as his mind faded, his new primitive insect ganglia being unable to maintain such complicated thoughts and memories. Eyes moved to the sides of his head granting better peripheral vision as Bianca grew concerned, he can't stay in here....too bright...no food...and...females...can smell...females...need... find...mate...

'So...hard...think...get...help...human...not...insect...musssst....go...females...mate...' were her last coherent human thoughts as the last features of the woman he once was faded away as his legs moved closer together as his thorax hardened into its new shape and his wings finished forming as intense lust washed over him, he needed find the females he could smell, needed to mate, to spread his genetics. The only difference from a 'normal' butterfly now was his size; he was slowly shrinking, but was still over a foot long. Flapping his large wings he took off and flew out of the bathroom into the lab, he could smell the pheromones of females of his species and was driven to seek them out. Fluttering around the lab he finally spied the large glass case holding several butterflies, and he used his size to lift the lid even as he continued shrinking, wriggling inside, the lid of the cage falling back in place sealing him in as he shrank to less than two inches in size, the transformation finally over. Finding a perfect mate he initiated mating and quickly coupled with her, his body quivering in ecstasy as he mounted the female and pushed his ovipositor into her sex. His last vaguely human thoughts finally faded for good as he ejaculated his mind away forever, wave after wave of intense sexual ecstasy sealing the transformation and making it permanent. She was an insect now, nothing more, right down to his DNA.

Bianca's fellow researcher's were delighted in the morning to find that somehow a male of the very rare species of butterfly on which they had been experimenting had somehow appeared in the cage with the females, and was energetically mating with them. They speculated that a female had undergone a sex change in response to the lack of males, but if this was case why were there now eleven butterflies in the case, instead of only ten?? Then their delight turned to concern as they found their friends scattered clothes in the bathroom, but no sign of her. The police were called, but her disappearance was never solved.

Eventually budget cuts forced the research project to shut down, they had no success in finding a longevity formula for the rare insects, and all the butterflies were released into the wild, there now being several hundred due to the prolific breeding activities of the first male. They did not know that indeed a longevity formula had been discovered, and used once, it was a shame the immortal butterfly could not tell his former colleagues. But then of course he was just an insect, with no memories of ever having been anything else as he started his new life in the wild, a life which would never end.

The End
