Step Moms Private Pleasure Interrupted

I've got the house to myself finally, and even though there's some housework that needs to be done, I decide I really need a little "me" time! I really start getting turned on, rubbing my pussy and stripping off my clothes. My pussy is getting so wet! Then I roll over and you, my stepson, are standing right there! WTF! I'm embarrassed and tell you to leave but the next thing I know I'm agreeing to let you stick your cock in me. But, just the tip, OK?
