My stepsister joins me for a steamy porn session with a surprising twist!

I was watching some hot porn when my stepsister walked in, surprising me. She didn\'t seem to mind and actually joined in, getting turned on by what we were watching. Things got wild as she gave me a blowjob and then we had sex. It was intense, with her moaning loudly as I fucked her hard. But the unexpected twist? She faked it.
