She caught her step-brother spying on her in the bathroom, she turned around and caught him jerking off. Surprised to see how big he was, and how turned on he got she decided he deserved to cum. She drops to her knees and starts blowing him, and the amount of pre-cum amazes and excites her. She then proceeds to stroke his hard cock and can't resist climbing on top and sliding her tight pussy down on his throbbing shaft. He then flips her over and pounds her pussy until he unloads his hot seed inside her. They now have a dirty secret.
