Seeking story Man/wife/bull(s)/peeping D*ught*r

I remember reading a story a long time ago where the cuck had(i think) arranged a breeding paty with his sl*twife..

Their D*ught*r somehow came home and was watching the acton through a partially open door...

then the enevitable happened...

Unfortunately I never read the end as I was disturbed from my reading.

I know it isn't much to go on, but if anyone has any ideas, I'd like to try find it again.

BTW I'm almost certain it was on either ASSTR or Darkwanderer.

Thanks for looking
