You are a happy blonde 11 year old named Cindy and was walking over to your best friend Josh's house. You had a birthday gift for his 13th birthday. You would be turning 12 in a month, but currently they would be celebrating his birthday. You arrived at his house and rang the doorbell. Josh opened the door where you said "Happy birthday!" then looked and saw Josh's pants were down... and he wasn't wearing any underwear. shrieking a little, but then something odd happened in your mind and became more accepting.

You giggled and said "Crazy talk. I don't think... I mean I guess this is kind of odd?"

A part of your mind was freaking out, but you felt oddly ok with everything.
Josh said "Get your clothes on and leave! I don't want to see what happens next if you stay!" and then...
