"Hm, I see..."
	A figure in a white lab coat peered over a culture sample, gazing through a microscope. Most called her Mercy, though she was once better known as Angela Ziegler, and she had been asked to study something, a small sample of material left behind at a crime scene. Normally Angela would turn down such a request, but the assassin's work had upset the entire city, the slow progress the doctor had made with humanitarian aid quickly undone. It was a miracle that they had even found where the sniper had hid themselves, but a nearby woman's scream of some sort alerted the victim's entourage, leading them to the hiding place of the assassin.
	A tinge of sadness, and even guilt, wormed its way inside of Angela's heart, her mind filling with the hypothetical. What if she was there, would she have been able to save the victim? But the doctor brushed those baseless woes from her mind, she was already working in penitence, negative thinking now would only affect her work. Still, Angela wished they had found something else to send her to analyze, whatever this substance the killer left behind was, to say it stunk would be putting it lightly, the heavy stench rising up from the petri dish threatening to suffocate her.
	"There appears to be...activity within the sample. Hinting at a biological function of some sort? Perhaps the perpetrator did not mean to leave this behind?" Next to Angela, a recorder etched her every word onto its tape, its recording to be presented with her findings and gone over afterwords. Deep inside the viscous substance, Mercy could make out numerous shapes swimming about, pushing themselves forward with their tails, the shape of these 'swimmers' were familiar to her but she couldn't quite place them... "Much activity in fact. The sample appears to be supporting life. I will take a closer look."
	Slowly, the doctor raised her eyes from the microscope, stretching her back as she did and stifling an urge to groan. Angela had been at this for hours, taking excessive care to prevent what little sample they had given her from going to waste, perhaps it was time for her to take a break? But as the doctor moved to shut off the recorder, her arm carelessly bumped into the microscope, knocking the entire apparatus onto its side, spilling the petri dish. "Ach, nonono! So careless of me!"
	Immediately Mercy scooped up the thick ivory liquid with her fingers, plopping the substance back into its container with a wet smack. Heavy panting came from the doctor as she watched the sample ooze back into its circular container, only for her to realize she had just let the anomalous material touch her skin. Just as she was about to leap from her seat, a deep pang in the recesses of Angela's mind stalled her. "O-oh? Aaahh!" A sudden gasp broke from the doctor's lips as she felt a small buzz of pleasure echo begin to build inside her. "I-I h-have just made...unintended contact with the material. M-my body seems to be r-reacting!"
	"I-I feel a deep sense of pl-pleasure." Self preservation battled with scientific inquiry as Angela tried to document the effects of her accidental exposure to the material, the buzz of pleasure beginning to build up into a warm haze, the stench of the goop in front of her losing its acrid bite. "M-My sense of smell appears to be d-dulling as well." Faintly, Mercy could feel her heart beating in her chest, feverish blood pumping through her veins, causing a blush to breakout on her face. As the the doctor's breathing began to grow heavy, she felt a twist in her guts. "Mngh... Th-there i-is a s-sudden shift!..."
	Arousal began to build up in Angela, her fingers digging into the edge of her desk as she fought to hold onto her composure. "V-very strong aphrodisiac effects!" Her skin felt blisteringly hot, the doctor feeling as though she may melt from the heat building in her core, beads of sweat breaking out upon her brow. "I-I think I will go p-purge my body nyaaaaaoooow!!" Just as the doctor was about to end her observation, for fear of what may come next, a wave of pleasure shook through her. It felt as though her body were being electrocuted, all of Angela's muscles flexing and spasming as a spontaneous orgasm rocked through her, the sensation almost frying her nerves. Faintly the doctor could feel a wetness growing between her legs, the blush on her cheeks growing deeper as she struggles to quiet her moaning, a desperate prayer in her mind that the currently running recorder allows editing out audio.
	"Th-the aphrodisiac is stronger than previously tho-mnk!" Once again, Angela's words were cut short as a jolt of pleasure shook through her. A wet, sticky slap echoed throughout the room as another wave of ecstasy threatened to drown Angela in its depths, a hefty cock slapping out from her nether's lips. "Wh-what is this!? I-I appear to have grown...a-a man's genitals!" The doctor was shook to her core as she slouched into her seat, eyes locked onto the length now sticking out from between her legs. Hesitantly, a hand moved down and touched the skin of her cock, causing an instant burst of arousal as Angela's fingers grazed her sensitive shaft. "Mnh! I-It's very t-tender!"
	The doctor's skirt grew damp as juices slid down the length of her new dick, a strand of liquid stretching from her fingertip to her new perverse shaft. "I-I can't b-believ-nff!" Plop. Angela's body almost went limp as she was dunked into the depths of pleasure once again, her pussy's lips getting stretched wide as two far too large orbs forced their way out, a loud messy plop getting etched onto the recorder's tape. "Ffffff! M-More changes! V-very overwhelming!" Sweat seemed to pour from Mercy as she was dragged deeper into a spell of arousal, her lower lips slowly sealing themselves around the base of her new cock, erasing any proof of their presence.
	As any evidence of Mercy being a woman disappeared, the doctor's package began to burn and prickle, as though a thousand tiny needles were prodding it. "Aaauu!" This tide of burning pain grew into pleasure as it spread up from Angela's ballsack and began to surround the base of her shaft, where her pussy once was. Digging her nails into the arms of her chair, the doctor's vision swirled as these feelings erupted inside of her, Angela barely able to reorient herself to glance down at her crotch. Looking back up at Mercy was her erect shaft, over a footlong and drooling pre, veins running along it, and at the base of the shaft she saw wiry hair rapidly growing from her skin, the prickling finally making sense. The sweat running down Mercy's body pooled into her new bush, hushing the irritation as her pubic mound grew wet, droplets of the doctor's perspiration draining through her jungle of crotch hair and down her ballsack.
	Every nerve in Mercy's body felt as though it were aflame, her only relief being the copious sweat running down her pale skin, and what cried for attention the most was her throbbing shaft. In her feverish daze of lust Angela lowered a hand to her cock, easily gripping it in her fist, "Mnh! P-Perhaps I need to j-just squeeze it out, m-make it run its c-course!" Mercy lied to herself, that she was doing this to get it over with, but the pleasure she felt when her palm circled around her cock made her almost climax right there, the doctor instinctively slapping her fist down onto the base of her shaft, squeezing it as hard as she could. "Fffffh!" The pale length shuddered in Mercy's grasp as she tried to hold back a climax, trying to quell her throbbing package as it grew taut. "Sh-sho goood..."
	Slowly, the doctor began to jerk her hand up and down her cock, sweat and pre getting slathered over her towering erection, wet slaps filling the room as Mercy leisurely pleasured her length. The room stunk of Angela's sweat and ball-musk as this point, her pubic mound holding onto a load of sweat as though it were a sponge, the weight of her wet bush coaxing the doctor into running her fingers through the mess of wairy hair. As Mercy ran her fingers through her crotch's forest-like hair, it felt as though her package had suddenly been pricked by the same needles as before, though this time Mercy knew what to expect, and a perverse eagerness grew inside her. Just like her crotch before, Mercy grit her teeth as the crease of her sack began to grow hairy and warm, her wiry pubic hair spreading down and lining her package with a luxurious tuft of pubic hair, sweat already dripping down it and making it grow wet. "Auh~, such a nice little f-forest I'm growing~..."
