「捕まったらあなたを責めます」ついに犯される義理の妹

My stepbrother Isaiah has a big crush on me.

He's always slapping my butt and telling me how hot I am.

I never really thought of him that way, but one day he asked me to do something,

and it actually really turned me on.

I did not expect to feel that way, and I definitely did not expect what happened next.
