I find my stepsister in my avoidance and I fuck her very hard until I come in her mouth

I look for my stepsister all over the house and I find her in my avoidance and I find her naked waiting for me naked in my room without me realizing it I spy on her and I masturbate seeing her naked in my avoidance without her seeing me and she ends up looking at me and tells me to go on the room so I can fuck her very hard
