2T4U/Aaron/Check on your baby sister Tiffany
From Create Your Own Story
Well, you could go see if maybe Tiffany might want to see this thing your penis can do now. You don't know how Missy might react to seeing you with your pants down, and you can't tell your mom or any of your older siblings, they might get you in trouble. Sometimes Tiffany still takes her pants off in the house though. Well, not any time recently, but it wasn't that long ago she used to do that. Suddenly, as you think about your little baby sister without her pants and pull-up diapers on, it makes your peepee get hard again.
'Oh no, why is it doing this?' You wonder, but this time it seems to feel even better than before, and somehow it seems to feel really good when you think of seeing Tiffany's bare privates.
