So I searched this artist and every single work of his is about little sisters in law.

@岬ちゃん, 義妹 means stepsister

It's not all stepsisters. Many of his works also feature blood-related sisters too; a real incest, not the 'fake' incest as in with stepsisters or in laws like the so-called incest in American porn. If you haven't seen those then you haven't seen all of his works.
