I caught my stepsister masturbating in bed and got her on my cellphone. She threatened to call the cops on me for being a creep who spies on his stepsis, but in the end my video arguments appeared more convincing to the point where she agreed to fuck me. Damn, that nice tight pussy was so wet and slurping I could barely hold myself from cumming inside. She loved it too cuz she invited me to do it again and promised to keep it a secret. Agreed!
