I sear had never meant for any of this to happen. I’m a grad student, biology major. I was an intern to a researcher studying a recently discovered virus that had unusual effects on its host, especially on pheremones. It had currently only been found in female chimpanzees, but there was mostly disregarded conjecture that it could cross species. My job was to take blood samples and run physicals on the specimens.One day i hate to say i wasn’t being as careful as I should have and i pricked myself with a needle from the sharps bag. This is a major no no, and i had to be quarantined for 5 days. nothing happened. I was in the clear, or so i thought.about a week later i woke up feeling incredibly horny, more than i had my entire life. It was weird, but enjoyable. I spent the whole morning jerking off, but i didnt really feel satisfied. weird.i came in to work still semihard. i tried to throw myself in to my work to distract myself, but it was difficult partly because of sex and partly because itwas so damn cold i could feel my nipples getting hard.suddenly i realized how insanely attractve my coworkers were. Katrina my fellow intern had the cutest little ass, perfect for plowing. And the professor. My god you could see the outline of the professors dick right through his slacks. It was then that it dawned on me that i was bisexual. how had i not realized it sooner? 3 months ago it felt like i was oblivious but now it seemed so obvious. i went to a gay bar that night, a little nervous. when i went in it felt like everyone was watching me hungrily. again, weird. I got chatting with a nice young stud named Nick, and soon we were making out in the bathroom. We decided to go back to my place and fool around.He started sucking my dick (which was magical) and i came almost immidiately. “ah” he said. “looks like we got a twink.” i looked down and was shocked to see myself far skinnier than i was used to, and my dick far smaller than i remembered it. It was odd, but what was even stranger was the fact that his dick wasnt in my ass yet. i bent over and let him roughly take my anal virgnity. i came again, and this time i didnt stop. i came in one long continued spasm as i felt gallons of cum leave my body. with every thrust i felt my ass thicken a little more, and with each moan my nipples felt a little harder and my chest a litte more cushioned. my god, i was turning female, and it was fucking spectacular. as my body lost its final mass, i felt something similar to a punch in the gut as my uterus formed. my testicles migrated to their prepubescant locations and i nearly shrieked in pleasure as my penis completely inverted. the last of my pearly white man-cum dribbled out of my pussy and mixed with the slick clear girl-cum that made my new pussy oh so wet.”fuck my pussy baby” i commanded, and Nick, the very gay, very anti-cunt pro-cock man complied with gusto. i came seven times that night before i collapsed in a well-fucked puddle.i woke up being eaten out by a now far twinkier Nick. It was even better than when he sucked my dick. after i came enough (thrice) i decide it was time to return the favor. I started sucking his dick and was immediately rewarded with a bellyfull of delicious salty-sweet cum, with just a hint of pussy. as he came the flavor of pussy soon overwhelmed the cum taste until eventually it was all that left. I lookup and am greeted by two tits and a very confused girl. looks like we were to be patient zeros of a hot new std the likes f which the world has never seen
