The new chapters got a nice story twist. I like that you introduced some adversaries for Innana's crew, that offers the story more possibilites
than being just a TF fest. ( Not that there is something wrong with a traditional, nice TF fest
)
If you want a suggestion for some new forms of TF, i think goats would
fit very nicely. they're pretty traditional, if you want to show some bestial
sexual urges.
Anyway, a nice series. I'm looking forward to the next part.
