Letting my step-brother fuck my thighs so I can borrow his car

Description: My step-brother just got a really nice bmw and he never lets me borrow it. tonight i wanted to go out with my friends and knew he had a date. obviously the only reason my scum bag step-brother would take a girl out is to try and fuck her so i come up with a plan. i know he has a thing for thick thighs, so i wear my tightest booty shorts and go into his room to ask him about borrowing his car. he obviously is going to refuse right away, so i jump on him and grind on him until his dick is hard. after that i give him my pitch, he can fuck my thighs, if i can borrow his car. he caves and cums all over my thighs.
