I wanted to do the ritual because Dave was always talking about what we wanted to do to girl's bodies, but never actually doing it. He was too shy, too introverted, too much of a loser. Sure, he was two years younger than me, and might come into his own someday, but I was sure that the girl version of Dave would be as sexually precocious as his big sister Sarah had been.
I'm twenty and in college. The guys on campus are immature, so I often found myself getting railed on the beds and couches of much older men in town. Their adorable suburban college town was home to plenty of old bankers and executives who would pay for cars to and from campus, plus a DoorDash delivery from some expensive restaurant.
Dave was in his senior year of high school, and lived with our father. I stayed with them during breaks, and I'm on spring break of sophomore year. Freshman year, I spent spring break on Daytona Beach letting men do shots between my titties or getting fucked on the beach at 4 AM. I even sucked off a cop to get out of a 'lewd acts' ticket.
I saw it among the many horny TikToks I watched. Between girlies dancing and squeezing their tits, guys flashing their bulges, cute dances, vivacious opinions, there was a 'did you know?' video. It asked Sarah if she knew about a magic ritual to turn your brother into a slut. No one had much attention-span anymore, so the video explained it in 16 cuts over ten seconds, with a voiceover. The final images it flashed were of a beautiful, sexy bimbo slut, with big jiggly titties and hips that begged to be separated. The bimbo looked just like the brother from the beginning, only, well bimbofied.
I watched it again and again until I had memorized every step. Fried into my memory, I put my phone down, and recited the steps. I pictured Dave turning into a wet, needy bimbo version of himself. Unconsciously, my hands crept to my wetness. My finger brushed her clit before I realized what I was doing. In an instant, I was plunging my fingers easily in and out of the impossible wetness.
That was last night. Tonight, I still had the panties I came into last night. They had dried fluids on them in a crusty, pale splotch. This was the only item of the ritual. It would realign his gender appropriately, using my genetic makeup. Thinking about it, I kept grinning at Dave, ignoring our daddy, thinking about how this was the last time he would have a dick, or feel it stir when he watched me jiggle my tits playfully. So I smiled, and flirted, thinking of that flesh between his legs which would transform into an even-more-eager pussy, ready for my fingers, my tongue, and the cocks of whichever boys managed to show up first.
