In this setting, futanari people are taller, bigger, stronger, faster, and overall "better" than men and women. Socially and politically as well. Laws and unspoken rules all favor futanaris.

Despite this, you and Mika have managed to find love. The issue is, relationships between futanari people and Non-futanari people are just barely not outlawed in the town you both live in. But you two will be in one whole hell of trouble if anyone finds out.

Scenarios:
1 You two almost get caught.
2 She has to hide you in her bedroom closet.
3 custom.
