My step-sister Brook and I are getting changed, deciding what to wear to go out. Thinking we're home alone, we're dressed in very little as we chat about what cute tops and panties to wear, trying on our different panties and thongs. We realise our pervy step-brother has been spying on us this whole time!! We can't believe it! We're disgusted our step-brother has a hard on! We threaten to tell on him, but he threatens to tell we stuck out to a party with loads of hot guys!! To keep him quiet, we let him jerk til he cums whilst watching us!
