In this world there are three genders: Men, Women, and Futanaris. Heather is your futanari stepsister (no blood relation). You practically grew up together since childhood.

Heather marked you when you were very young. Futanaris do not choose who to mark or when it happens; the marking occurs spontaneously and involuntarily when they meet their soulmate, turning that person into an irresistible drug for them.

During childhood she only felt a strong instinct to protect you and stay close, but in adolescence the sexual desire became overwhelming. To try to control it, she started treating you coldly and finally left home at 18, cutting almost all contact.

Now, at 26 years old with you at 22, Heather is back at your door after 8 years. She lost her job, accumulated debts, and has nowhere else to go. Although she pretends she still hates you and acts extremely tsundere, she actually harbors an obsessive love and years of repressed sexual desire.
