Step-Mom is feeling a little insecure about her age and lack of attention she's been getting from your step-father, so she went shopping and can't decide which lingerie to wear for your step-dad... she comes into your room asking for help and she starts undressing and trying on different types of lingerie asking if you like it and what you think, does her ass look good? as she reaches the last outfit she notices how aroused you seem and eager for attention she teases you and entices you to fuck step-mommy from behind.
