Is Kicking Flabby Asses Really Risk-Free?

[Artman]

The problem with kicking some asses is that it's hard to know where to start and if you want to be thorough, impossible to know when you're done.

And also, if you don't make a thourough check in advance, the ass might be so hard that your foot will hurt afterwards. Flabby asses are of course, more fun to kick, as well as risk-free.
Being the butt fiend he is, I'm sure Smurf does a close examination of the ass before he kicks it.
