Demonseed Prison ~Prison of Enticement~

A prison simulation game of ejaculation endurance, with 70 base HCG images and over 50 H scenes.

A male-submissive (M) game about friendship shattered by sex, seduction and malice — and choices that stain your own hands with evil.

Story

Ally nation Sakirufia versus enemy nation Elimine. Their long war has advanced with the Sakirufian army in the ascendancy, and the fighting is finally entering its endgame.

Then the Elimine army launches a surprise assault on Northern Area Command — the site of a front-reorganization conference laying the groundwork for a ceasefire. The eight officer candidates, the next generation of Sakirufia’s leadership, gathered there are taken prisoner.

But Elimine is no monolith either. Though its will to fight is not yet broken, a movement has begun searching for a ceasefire to end the drawn-out war.

“If we keep eight enemy officer candidates in custody while ceasefire talks are underway, it could jeopardize the negotiations themselves.” Acting on the judgment of Elimine’s Minister of Military Affairs, the two nations’ diplomatic and military authorities open talks.

The final accord: 72 hours from now, the eight prisoners will be handed back to Sakirufia at a designated point on the border. A provisional transfer agreement. All that remains is to wait out 72 hours — but the prison holding them is not lenient enough to make that so simple.

The wardens cast a forbidden curse on the captured candidates: the Curse of the Sexual Slave. It blends your soul into your semen — once you ejaculate of your own will, even once, you can no longer defy the partner you lusted for. Yet because that power is so immense, one absolute condition exists: it never happens unless you yourself, from the bottom of your heart, want to ejaculate. Force alone can never make it happen.

So the wardens seduce, corner and inflame the young men, bending their own wills toward degradation. Their goal is singular: make the next generation of Sakirufia’s leadership utterly obedient, and wring out their military secrets.

Endure until liberation, 72 hours later? Uncover the information hidden in the prison and expose the enemy nation’s designs? Or yield to the temptation and choose corruption with your own hands?

A simulation game of seduction and ruin, set in a prison steeped in malice, lewdness, temptation and corruption.

Characters

Nate Guardred

The protagonist. One of the officer candidates of the Empire of Sakirufia, and the leader who holds the eight together. Refusing to yield to temptation, he endures the lewd prison life, determined to bring his comrades back home with him to the very end.

Prison Warden Dahlia Berry

Warden of the prison where Nate is held, and head of the guards. The ends justify any means for her: she will submit to any act and can play whatever personality the moment demands. A cunning woman who uses that to throw the protagonist into confusion while corrupting the other candidates as well.

Deputy Head Guard Vanessa Rain

Dahlia’s right hand, entrusted with all personnel matters inside the prison. She has felled countless men with her huge breasts, and schemes to expose any breast-lover among the candidates and drive him to ruin. Her boyish, domineering personality and powerful physique overwhelm the candidates — she is usually the one to initiate the seduction.
