In this continuation of the "Step-Mom pegs your ass on your birthday" series, it's now your 20th birthday and you've finally conceded that you're gay, you love being fucked in the ass so much. Your step-mom assumes that like the last year, you'll be wanting your ass fucked again as your present. She decides to give this to you, but with one exception. She wants a little something for herself this year. She wants the step-daughter she's always dreamed of. She slides her strap on in and out of your ass as she talks about how she's going to dress you up and treat you like her little sissy bitch.
