My stepsister is so nerdy, I never thought she would have so many fans. I guess she is hot, so people love watching her masturbate and fuck in front of a camera. Besides, she wears all kinds of sluty outfits. I didn't know nerdy girls could be so bad! I was rock-hard for my stepsister. I tried to resist temptation as much as I could, but then she said she needed to record content for her followers and asked me if I was "too cool" to fuck her. Fuck. Was I? Definitely not when she's wearing those devil horns, tiny skirts, and can fit my entire cock in her mouth.
