Step Mother Knows Best

My step mother is always on my case and thinks she knows it all. She is always telling me what to do and that I am to young to know everything. She saw me masturbating and even told me I wasn't doing it correctly. My step mom showed me how to do it and then we had sex with each other. She sure knows what to do in bed and I came so hard, I didn't even know where I was. Maybe I'll start listening to my step mom.
