Futa Step-Sis Treats Your Condition

This time, the person with a critical hormone deficiency requiring daily semen injections is you! Will you let your futanari step-sister fill your guts with her medically-prescribed jizz every day? The ongoing adventures continue as Momoe takes you to the doctor's office after you were starting to feel lethargic and fatigued. After some tests, the doctor came back with some bad news: you're suffering from an incredibly rare hormonal deficiency that has only one known treatment: daily semen "injections", typically taken vaginally or rectally, but oral route also works. And because the dose needs to be injected deep into the receiving cavity, a simple syringe isn't sufficient, requiring either an expensive device or straight from the source. There are donors at the clinic, but you'll need to commute daily, taking hours out of your day. Plus, the treatment is pretty expensive. Without treatment, you'll eventually experience further fatigue, reduced movement and appetite, then organ shutdown and death. So it's either daily trips to the treatment center, or find a source closer to home. Say... why is Momoe looking at Sachiko like that?

So it's either daily trips to the treatment center, or find a source closer to home. Say... why is Momoe looking at Sachiko like that?

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. The scent of her vanilla shampoo wafts across the room as she nervously twists a strand of her bob-cut black hair around her finger.

"So you see," Momoe explains to Juno, gesturing with her hands, "the doctor says you need 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 with a nervous cough. "Well, uh... that's certainly... medical," he mumbles, clearly out of his depth with anything involving bodily fluids. The faint whir of his laptop in the background suddenly seems deafening in the awkward silence.

Sachiko's mind races as the implications hit her like a freight train. 'Oh fuck oh fuck oh FUCK! They need... needs CUM?! Every day?! And Mom is looking at me like... like she wants me to... OH GOD MY DICK IS GETTING HARD!' Her heart pounds in her ears, and she can feel her cheeks burning crimson.

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 even redder as she shifts uncomfortably. Her cock strains against her panties, already leaking precum at just the thought. The room suddenly feels like a sauna despite the air conditioning humming softly.

'She knows! MOM FUCKING KNOWS WHAT I WANT! She's basically telling me to... to give them my cum every day! To fuck that pretty mouth or that luscious ass or... JESUS CHRIST I'M GONNA EXPLODE!' Her hands tremble as she grips her skirt, trying desperately to hide the obvious tent forming beneath the fabric.

"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..."

Sweat beads on her forehead as she steals glances at you, her brown eyes wide with a mixture of panic and desire. The sound of a car passing outside seems to echo through the silent living room.

'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!' She takes a deep breath, her ample breasts rising noticeably with the intake of air.

"W-what exactly would... um... how would the treatment work?" she squeaks out, her voice barely above a whisper, as she tries to maintain her composure despite the growing pressure in her panties.
