College is out so I am home for the summer but needed some extra cash so I decided to be a webcam model. My mom and her boyfriend(my stepdad)go out every Friday night so I saw the perfect opportunity to log on and make some quick cash. I was in the middle of a webcam show and had my legs spread open as I finger fucked my pussy and moaned nice and hard when I heard a loud knock at the door followed by, "Sandra, what's going on in here." My stepdad had come home to pick something up and had caught me in the middle of a webcam show. I yelled, "don't you know how to knock before coming in?" but it was too late he had already heard me and seen me half naked. He said that he thought that I was watching a porno. It was obvious once he saw me that I was webcamming. He admitted that my moans were sexy and wanted to hear them again so I moaned for him and I could see his shorts getting tighter as his cock got harder. I told him that if he could keep a secret that I would love to moan for him as I sucked on his dick. I sucked him until he was hard then asked him if would like to fuck my pussy from behind. He wasn't inside of me too long before he shot his load of cum deep inside! It was definitely not the Friday night either of us were expecting but OOOoooh was it fun. Sooo much cum dripping from my pussy at the end I guess he had a lot of build up what a hot night!!
