WARNING!!! THIS IS WHY step-BROTHERS AND step-SISTERS SHOULD NEVER WATCH PORN TOGETHER!! MUTUAL MASTURABTION LEADS TO SEXUAL INTERCOURSE... FOLLOWED BY THE step-SISTER'S ASS BEING COVERED IN SPERM!!!! Rosalee and her step-Brother step-son are home alone....watching TV...and there is absolutely nothing on. As they channel surf....they eventually wind up in the PPV area of the guide....and make a startling discovery!! Apparently step-Mom and step-Dad have added the "nudie channel" to the cable package!! The two Siblings start watching the porn together ….and after a few minutes...things get....well…."weird"! Rosalee confesses that, usually when she watches porn.....she masturbates. step-son admits that he usually does too....so the Siblings decide that it would be alright if they both played with themselves while watching. After a few minutes of that...they decide that it wouldn't be "too harmful"....if they reached across...and played with each other!!! So...Rosalee strokes step-son's cock....and step-son plays with Rosalee's pussy...while they continue to watch. Pretty soon....their hormones can't take it anymore...and they agree....to fuck each other silly!!! step-son fucks his older step-Sister hard, until he cums all over her great big ass!! This is why....step-Brothers and step-Sisters should NEVER watch porn together!!!
