Note: I do not own the rights to the L word and this is a world where people are hornier and more tolerant of genital differences than our 2000s or even our 2020s.
Shane McCutcheon was a ladies' woman and was an unusually beautiful hairstylist. She loved her life as she enjoyed her job, chatting with her friends at the Planet Cafe, and got to meet many beautiful women, even straight women, in clubs and bars in the evenings who were astounded by her beauty. Shane had a nasty surprise at one party when she drank a spiked drink inadvertently. Alice Pieszecki had done this as a prank for her close friend after a fight and wanted her to experience erections like a guy every time she saw a woman. The drug Alicen had spiked hane was called "phallic", which when taken by a cis woman, would irreversibly turn Shane's clit into a dick and her ovaries into testicles while sealing off her old genitals as if there was never a pussy there.
The next morning, while sleeping in her white boxer briefs topless, Shane discovered things were not quite right. She got up and looked in the mirror and saw a bulge in her underwear that looked "male". She then removed her underwear found a 5 inch dick and two small testicles where her pussy used to be.
Shane wasn't mortified at her new genitals, but intrigued. Shane, of course, had long used a strap-on during sex and told herself "It feels like having a permanent strap on."
