Stepmother masturbates in the car to invite him to fuck

The stepmother asks him to drive her somewhere and the boy is surprised because she sits in the back seat. The woman opens her legs showing that she is not wearing panties and starts touching her pussy. The boy looks all the time at what the stepmother is doing and can't believe it, getting very horny. She shows him how she masturbates and the boy drives straight home, where the woman gives him a spectacular blow job on his big cock and then he fucks her pussy.
