Fucking stepsis on a rebound

My stepsister is very upset, sexually frustrated and on a rebound after her boyfriend broke up with her, and being a good stepbrother I give her a helping... oh, well, a helping fuck. We've had this one time before when she gave me a handjob, and now we finally went all the way from some nasty deepthroating coming my way to me fucking her brains out and cumming right in her greedy mouth. And I'm living under one roof with this slut… wow!
