Futa’s World of NTR

Ten years of hiding a chastity belt from her foster family, and the day she starts high school it comes off. She's not interested in easing into anything.

The setup is simple: a futanari protagonist surrounded by classmates who are either already sluts or about to be turned into them, chasing every immoral impulse she's kept locked away for a decade. The plowing starts from day one, and the source is upfront about that being the whole point.

Play is straightforward visual novel territory: read, click through scenes, watch the school around her get progressively less innocent while other people's relationships fall apart in the background. Netorare is baked into the premise rather than bolted on, so expect the cheating and betrayal angle to run parallel to the protagonist's own escapades throughout.
