About this game

The developer's description, from the game's Steam store page.

Ashe is a 20-year-old futanari who is plagued by insecurities and anxiety. Constantly overthinking everything, she spends most of her life in her room, secluded from the world. She has never had a relationship, her work as a delivery girl is boring at best, and her ambitions are non-existent.

But things are about to change when her former closest confidante finally returns. And when someone discovers her biggest secret, Ashe's life is irrevocably turned upside down...

Eruption Imminent is set in a modern, alternate world where men don't exist. In this sapphic paradise some women have female genitalia, and some have male genitalia. And then there are the rare "duplo futanari", which have both. These "duplos" have a rather bad reputation, describing them as lustful sexual deviants. This in turn has led to many duplos hiding their identities, including our protagonist Ashe.

The narrative is presented as a choice-driven visual novel that lets you make decisions during key points in the story. Lead the protagonist down three distinct paths, which unlock exclusive dialog options, romantic partners and sex scenes. Each path slowly pushes Ashe's personality in a certain direction, which will change how she will think and react to the situations she finds herself in.

The vast majority of sexual content and all relationship paths are optional, giving you the power to decide which threads you'd like to explore further.

Relationship paths are neither exclusive to each other, nor are they treated as isolated story lines. Instead you'll see relationships intermingle with each other, reacting to your choices, and occasionally unlocking additional options for scenes or story threads.

Set in an all-women's world, romantic options and sex scenes are exclusively sapphic. The protagonist is a futanari who can engage in a wide variety of lesbian sexual content with women or other futanari.

Depending on your choices, Ashe can take a more dominant or submissive role. There is optional content that explores the themes of group sex, sharing, cuckolding, and a variety of other kinks.
