I forgot about Banana's anthro cow transformation sequence fits the theme here. Not sure which one has the curse but after a nice date on time their true love's first kiss kicks it off.

Wish I can see the fate of that couple now, but I guess I have to pay for
that and I don't have any money.
Two explorer stories one with explicit sex and the other has tame macro TF.
First one is a couple of archaeologists went to investigate a lost civilization in Australia and find ancient eggs. The woman is affected by the egg and gets turned into an anthro kangaroo while admitting her love for her partner.

Second one is about the same but the trigger is a rubber rose petal that transforms the woman into a giant anthro rubber skunk (with a long flexible tail which is also my kind of thing) and the partners both fell for each other after the change.
