You drink it all

You start to suck on your bottle full of cum, loving its warm salty taste. Your "mommy" looks proud and starts to finger herself while watching you. Once you are done, she decides to let you sit and play for a bit with your toys.

You realize you need to go to the toilet. Staying in your role, you decide to just piss and shit right in your diaper. As you go, you can feel your diaper fill up and get very warm. You can start to smell it all.

She suddenly asks, "Did baby Billy have an accident?"
