Anyone who's ever had a spanking with a butt plug inserted can certainly verify that they add a certain dimension to the whole experience.

As a rule, I like to keep at east once butt plug in the house for a variety of reasons. Mine doesn't see too much use these days, but it's still there.

However, were my girl to tell me to stick it up my ass, I'd demonstrate how that butt plug works and exactly what kind of element it adds to a generous spanking.
