Sticks and Stones etc, etc... It's not something to be so worked up over. And again I wish you success in your endeavor.
I'm not even denying it's existence or the existence of something very similar. Robs descriptions and screenshots are often inconsistent. Nicholas3 For example ends with a 4 minute shower scene of the guy washing off, fully erect with zero mention of that on the videos page.
It just feels extremely unlikely a version with an additional full sex scene with either of those popular MC models would not be the primary version being shared around online.
