The Milk Competition - A Best Friend's Secret Seed

Rachel would do anything for her dream career, even sign up for a high-stakes science experiment. But the transformation went further than she imagined. Now, she's a massive Hucow with a problem: her swollen, heavy breasts have been bone-dry for a week. With the final weigh-in approaching and a life-changing job offer on the line, Rachel is desperate. The girl who produces the most milk wins it all, but Rachel's "machinery" won't start without a specific catalyst.
Desperate, she calls Kyle-her best friend, her confidant, and now, her last resort. Rachel knows that to jumpstart her system, she needs more than just medicine; she needs the one thing only Kyle can provide. When she asks him to fill her with his hot seed to trigger her production, the lines of friendship don't just blur-they ignite. Will Kyle's "contribution" be enough to land Rachel the job, or will their scientific collaboration lead to a permanent bond neither of them expected?  Friends to Lovers Desperate Measures Sci-Fi Transformation / Body Mod Breeder / Fertility High Stakes
