Go for the 45 year old. It is tiresome to always be reading descriptions of long, lithe, nubile bottoms with little jiggle. Mature bodies with Rubenesque qualities paint more vivid images. and in writing, isn't it all about the pictures the readers can imagine.
Hahaha. If you've read any of my stories, then you already know that all my spankees have generous, chubby bottoms, regardless of age.
That said, the older woman has already won the vote.
