My Wife and Sister-in-Law Were Trained by a Fitness Trainer to Become Pregnant Breeding Pigs

My Wife and Sister-in-Law Were Trained by a Fitness Trainer to Become Pregnant Breeding Pigs is a 2D kinetic novel for players who want a dark, slow-burn corruption story. The tone stays heavy and explicit throughout, without lighter detours.

Story

The protagonist's wife and her younger sister take jobs at a local gym, where a trainer's influence over them grows. What starts as fitness instruction turns into a steady process of moral corruption that reshapes both women.

Gameplay

The game plays as a kinetic novel, meaning the story moves forward on rails with no branching choices or sandbox exploration. Players read through scenes as the corruption arc progresses, watching the relationships and behavior of the two women change stage by stage.

Features

• Fixed-path narrative focused entirely on one corruption storyline
• 2D character art depicting the story's key stages and outcomes

Notes

This is a linear NTR-focused title with no player agency over outcomes; readers looking for a story where the protagonist keeps control of the relationship should look elsewhere.
