In first place, we have succubified Ranma learning how to properly care for her body (plus a sort of follow up.)
Behind that we've got slightly put out naga Ranma, a little frustrated at her perpetually lost lover boy, and finally in third place we have a petite futa-mousegirl screwing a busty cowgirl, which seems maybe a little on the nose?
I'll be finishing up the first place fairly soon, hopefully. Cheers!
