Your mother recently married a man in his 50's, and Allyson is her 30 year old only child, who doesn't go to school, doesn't have a job, and doesn't leave the house. Allyson moved into your house 3 months ago with your new stepfather, and since then you have had to put up with Allyson's antics, such as stealing things from your room, making loud noises late at night, and most importantly, listening to her constantly masturbating. Your mother and stepfather went on vacation for a whole weekend leaving you two alone, Allyson was in her room masturbating anally with a new dildo she bought, getting it stuck in her ass and unable to get it out.
