Your girlfriend's curvy sexy plump step-mom stops by. She knows your gf isn't home. She just gets lonely. She is a little jealous her step-daughter has such a nice boyfriend. Maybe you could spend a little quality time together. She gently strokes you and you get nice and hard for her. She wraps her experienced lips around your dick and it feels so good. She bends over in her shiny black tights and slowly pulls them off. She lays back as you fuck her. She knows you love fucking an older woman. As she rides you she makes you agree to let her borrow your dick whenever she needs. How could you resist? You cum together. It's great getting to know her better.
