From what I understand about Gwendy's farm from the wiki and walkthrough, Gwendy's relation should become submissive at some point (if you win enough) and open up an avenue with the anal beads. However, I have gone at it for quite a bit and... it doesn't seem it's going anywhere. Also, supposedly there's one of the scenes (pre-market) that involves the horse guy. However, I have yet to see anything beyond milking with Gwendy or feeding the cattle with the sheep... are these things not yet implemented?
