Brother spies on his sister's slumber party from on top of a roof and gets caught

[DaddyNeedsDaughter73]

I don't really recall much more than what i posted in the thread title. other than Sis is having a slumber party and Bro crawls out of his window and on to the roof to watch what they are up to. He gets caught by another female and then they both proceed to watch.

I seem to recall that there was only one chapter available at the time (must be well over a year ago now) and sadly I wasn't logged in to my account when reading it to bookmark it.

Is anyone able to point me in the right direction?

Thanks in advance.
