Watched by stepsister!As punishment she has to lick my PUSSY

What a slut my stepsister is! For weeks she has been secretly watching me in the washroom and when she is already watching me, she can sometimes taste my PUSSY. I have to admit I find her really cool!! That's why I've wanted for a very long time that she licks my cunt properly! Just thinking about it has always made me wet ;) So I had a good idea after all, don't you think?
