Stepmother Effect is a sissification porn game with real pics and video, written by K17.
You play as a young man living under the same roof as your dominant stepmom - while battling a secret porn addiction. But she has plans of her own.
Multiple paths can lead to submission, transformation, or something even more daring. The question is... will you fight it, or embrace the change?
