My stepsister always walks around the house and tans naked when the parents aren't home and this time I decided to film her ass to show my buddies at the gym. When she caught me spying on her I tried to make it look like an accident, but my hardon totally gave me away. I thought she'd tell on me, but she preferred to just fuck me and share the secret. If only I knew my stepsis was such a slut with a cock-hungry mouth and a tight pussy! Now I know!
