My slutty baby sitter

Your baby sitter just put the rug rats to bed and she decided to relax on your bed when you find her there. She really needs this job and she will do anything to keep it. You do not have the heart to fire her, so you decide that a little play time will be acceptable. She lowers her top and you see her small titties. They are barely A cups. Next she takes off her shorts and you see she wears no panties. You worry about her age, but she is finally 18 years old. Mikayla also knows how to keep a secret, so you take out your step-daddy cock and start jerking off. Her pussy is tiny and tight and your dick grows as she fingers herself right there on your bed. You fuck your wife in this bed, and it seems wrong and dirty to be doing this now, but you cannot stop yourself. It gets ever worse when she asks to touch your cock. You move closer and her small hand grabs hold and starts jerking you off. She loves your big cock. It surprises you when she calls you "step-daddy," but you love it.
