Tipster Sam informed me of two recently released scenes by Corbin Fisher that showed poop.
The first one was with Jacob and Kyle that can be seen at the start of 18:33 minutes when Jacob pulled his cock to show his cum. This was already reported by SUGP.
The other one was the bi scene of Jasper & Marc where the poop can be seen at the start 16:14 minutes.
They even changed position while the poop was dangling on Jasper's cock.
