"What was that…?" The Lifeform/Bacteria TF [PART: 1/??]

You had gotten pretty sick recently, even coughing up some weird black substance. You didn't want to go to the doctors, because you were sure it was just the flu, and you HAD been eating a bunch of things with black dye in then, so you were sure you're just a little under the weather.

You had recently run out of medicine for the headache you were also pretty regularly having, so you begrudgingly had to get in your car and began to drive to the local drug store, coughing up a bit of that same gross black shit all over your hand as you drive. But just as you reach for the drink in your cup holder to help with your irritated throat that felt like you had swallowed knives, your car's tire hit a pebble on the road just at the right angle as you wrapped your hands around the drink, and you felt something drop in your stomach. Without even knowing, you felt as if this specific set of events had been too perfect, yet too imperfect, and you barely had another second to realize what was about to happen, before you suddenly fell through your car seat with a cut off yelp. And you swiftly fell through the ground and reality itself, slipping through the atoms as you eventually landed on damp carpet with the wind knocked out of your lungs.

When you eventually got up with a groan, you were met with endless yellowed halls, and the buzz of fluorescent lights above that were already growing insufferable. And just as you thought this day couldn't get why more confusing,as if fate decided, the sickness you thought was merely the flu began to react to your surroundings, and all your symptoms grew worse by tenfold. The pain in your stomach grew worse, so bad you doubled over, your muscles were suddenly sore and aching, and you were coughing up possibly gallons of inky black, coming out in massive bursts.

You kneeled there, coughing up so much of this weird substance as you realized this was much worse than the flu, and then this virus began to work even more of its disgusting magic, and your body began to warp and change: your skin bubbled up and began to grow darker and darker, slick with panicked sweat that swiftly turned into more of that substance. The inky black your were practically vomiting out by this point was slowly slithering up your body, seeping into your clothes and skin, before beginning to transform you further. Your body began to lengthen and grow taller, barely growing and thicker to compensate, except for, weirdly, your hips and thighs. Weird, vine-like tendrils made of that black slimy stuff wrap around your limbs and body, gently massaging and shaping your form even further yet. You just wanted to scream out for help, to anyone that may be nearby, but the pain in your throat had grown even worse, and the substance flooding from your mouth physically kept you from doing so. And just as you thought nothing else would change, panic gripped you even harder as the tendrils slipped below your slowly tearing pants, wrapping around your cock and beginning to massage and squeeze it as well, making it slowly shrink and retreat into your body, eventually replaced by smooth, slick lips that twitch and clench under the touch of the tendrils. The substance had began to congeal as it did its job everywhere else on your body, bunching up and ballooning out on your chest, jiggling and steadily inflating until they were twice the size of your head's original size, before you had begun transforming.

When the transformation had finally slowed to a stop, one last puddle of inky blackness slipping out of your fanged mouth, you could finally scream, but it came out as a bellowing roar, from how messed up your throat had been. The pain had gotten to become too much at this point, and you finally collapsed into unconscious, landing on the even more soaked carpet with a resounding "THUMP!".
