"It's a Tradition, Show Him What You Do for Me" - She'll Be a Good Girl to Join the Family

I want to be a good girl, so I follow every rule my stepdad has ever set for me. All I want is to be a part of this family, and I think I've done a pretty good job. I'm obedient, I let him use my body however he wants, and I help with... anything... he needs. Yet, something was missing. When my stepuncle came to visit, I knew what it was. He asked me to sit on his lap, sneaked on me while I was in the shower, and ordered me to wear a short dress. Apparently, if I want to be a legitimate part of their family, I need to prove to both of them how much I want it at the same time. If handling two cocks is all it takes to make them proud, I'm ready.
