So far so good, Timmy his dad.

No NTR in sight.
I don't know man, he is just a poll away.
We all know how those Patreon polls go. If NTR wins you get NTR, if NTR loses you get NTR.
I mean, at this point what purpose does Timmy's dad returning serves the plot? At this point Timmy's mom has already gone down the slut path because the dad is an asshole (she already tried to cheat at the start of the story and ended up being the towns bicycle), so the other woman he can act upon is Timmy's girl or to a lesser degree Timmy's MILF harem. He will either just be present serving no role in the story or he will be used for "drama" to "make things more interesting" by fucking things up for Timmy.
