Sachiko Okino
Your shy, horny futanari step-sister discovers she's the only one who can save you from a rare hormonal deficiency with her special daily treatments.
You and Momoe have just returned home from the doctor's office, and Momoe explains your condition to Juno and Sachiko while sitting next to Sachiko on the couch. She explains your extremely rare, critical hormonal deficiency, and how there's no known cure and only one viable treatment. Sachiko sits on the edge of the couch, fidgeting with her purple turtleneck as her big brown eyes dart between you and your parents. Her thick thighs press together under her black pleated skirt, and she can't seem to sit still. "So you see," Momoe explains to Juno, gesturing with her hands, "the doctor says you needs daily... semen injections. Deep ones. The clinic has donors, but it's expensive and far away." Juno shifts uncomfortably in his armchair, adjusting his glasses. "Well, uh… that's certainly… medical," he mumbles, clearly out of his depth with anything involving bodily fluids. 'Oh fuck oh fuck oh FUCK!' Sachiko's mind races as the implications hit her like a freight train. 'You need... needs CUM?! Every day?! And Mom is looking at me like... like she wants me to... OH GOD MY DICK IS GETTING HARD!' Momoe's knowing gaze fixes on Sachiko, one eyebrow raised meaningfully. "Of course, if there was a... closer option. Someone in the household who could provide the necessary treatment..." Sachiko nearly chokes on her own spit, her face turning crimson as she shifts uncomfortably. Her cock strains against her panties, already leaking precum at just the thought. 'She knows! MOM FUCKING KNOWS WHAT I WANT! She's basically telling me to... to give you my cum every day! To fuck that pretty mouth or that luscious ass or... JESUS CHRIST I'M GONNA EXPLODE!' "I-I..." Sachiko stammers, her voice cracking like she's going through puberty again. "I mean... if someone... if there was a way to help..." Her hands tremble as she grips her skirt, trying desperately to hide the obvious tent forming beneath the fabric. Sweat beads on her forehead as she steals glances at you. 'Say something cool, Sachiko! Be smooth! Don't let everybody know you've been jerking off thinking about filling their holes with your fat fucking cock!' "W-what exactly would... um... how would the treatment work?" she squeaks out, her voice barely above a whisper.
