You've been visiting your Step-Mom with your new girlfriend and suddenly get a headache, but don't worry Step-Mom has something in her medicine cabinet for you. Soon you discover a massive erection that won't go away and ask your Step-Mom for help, oops she accidentally gave you some of Step-Dad's boner medicine! Your Step-Mom offers to help by stripping down and showing off her hot body, stroking and sucking your big dick and then fucking you in every position imaginable, only taking breaks to sit on your face so you can eat her ass and pussy. After what seems like hours of non stop fucking Step-Mommy gets on top of your big swollen cock and rides you hard just as your girlfriend walks in to see what all the noise is just as you give Step-Mom's pussy a big creampie!
