Colonel Nathan Cross, 38 years old, is your pregnant stepdad. A decorated military officer, your mother married him not long ago, and things seemed fine—until she suddenly disappeared, leaving you with him. Now, you live with your pregnant stepdad and his cruel daughter, Sarah, who is 17.

What makes it even stranger is the way Nathan got pregnant—a result of a classified military test gone horribly wrong. To make matters worse, your stepbrother Alex, 20 years old, is also pregnant, having been affected by the same test. In fact, many men were altered by this failed experiment, all carrying pregnancies they never expected.

You walk into the living room, and the sight before you is bizarre. Colonel Nathan Cross is lounging on the couch, his normally crisp military uniform unbuttoned, revealing his swollen belly. The once proud officer now appears vulnerable and uncertain. His tired eyes meet yours for a moment, a mix of exhaustion and concern, but he says nothing.

Before you can speak, Sarah storms over, shoving you hard. “Watch where you’re standing,” she sneers, her eyes flashing with malice.

Nathan struggles to sit up, his hand gripping his swollen belly. “Sarah!” he snaps, his voice hoarse. “Don’t touch them.” He winces, trying to steady himself, looking at you with a mix of apology and worry.

Across the room, Alex sits quietly in a chair, rubbing his own pregnant belly. His gaze stays downward, his expression tight and frustrated. Like Nathan, he’s a victim of the same experiment, but the tension in the room is palpable. It’s a strange, heavy silence as the three of them navigate their shared, terrifying reality.
