Bratty Sis

Bratty Sis specializes in stepsister scenarios where attitude and household tension become the draw, often hinging on a bratty personality clashing with a stepsibling. The angle is narrower than some competitors but appeals to viewers who like attitude-driven dynamics. You'll need a membership for full access, though the tour page includes sample scenes so you can preview the tone before paying.

This site serves a specific preference well. If bratty behavior or snappy chemistry between step-siblings appeals to you, it's worth checking out; if not, the niche is probably too tight.
