I'm excited to hang with my big step-sister, Lizzy James! I plop on the couch next to her and start chatting away! But...something's weird. Lizzy is sitting kind of funny. And was that a crinkle I just heard? My big step-sister is wearing my diaper! That's mine! She stole it! I can't believe my big step-sister would steal my diaper! I tell her she needs a spanking because she was naughty and that's what happens when I'm naughty. She doesn't think it'll hurt, so she agrees. I tell Lizzy to take off my diaper and get over my lap. Boy, is she surprised at how stingy this spanking actually is! ...

I'm excited to hang with my big step-sister, Lizzy James! I plop on the couch next to her and start chatting away! But...something's weird. Lizzy is sitting kind of funny.

I tell her she needs a spanking because she was naughty and that's what happens when I'm naughty. She doesn't think it'll hurt, so she agrees. I tell Lizzy to take off my diaper and get over my lap. Boy, is she surprised at how stingy this spanking actually is! I make her butt super red while we banter and I tease her for getting spanked by her baby step-sister. But she wants to play baby and wear my diapers so much so I make her put my stolen diaper back on, and I put a pacifier in her mouth. With a freshly padded butt and a paci, my big step-sister climbs over my lap for some humiliating diaper spanks before I send her off to time-out!
