We really want to go out and we are all dressed up, but we just need a lift. Oh come on Brother, please?? We will do anything in return, just this one time? "OMG, ewwwwww!!! No, we definitely can't do that! We're your Sisters?? Hmmm, but we really do need you and your car. How about if we compromise and we tell you how to jerk it instead?" We both tease you, flashing our boobs and pussys and giving you LOTS of dirty talk and masturbation instructions. Eventually we end up getting far too into it and we both BEG for your cum all over us. Come for your Sisters ;)
