Assology is not just a philosophy.  Tailonomics isn’t just rhetorical.  Sometimes you have to go out into the field, really take an anthropological approach to the study of assology.  I believe a major shift has occurred, an evolution that may change the landscape of natural tail pieces forever…

After much research, I present, the Muscle Butt!

Crikey!  What a beaut! He-yah we have the great Blac Humpback Tail.  That bikini is holding on for dear life.  Fighting for respectability.  Fighting a losing battle I might add.

There is a little extra heat on that profile shot, but you know Serena is in shape though.  Hell, I’ll say it, I’ll take a little texture for this kind of heat.  I don’t want to ignore that J game taking place up there, but my doctorate is in Assology.

Now there is something no one has ever seen before.  An ass that actually takes on a life of its own.  Here the Muscle Butt actually appears to be attacking its host.

RUN SERENA RUN!  DAT ASS IS RIGHT BEHIND YOU!

Man this is like that scene in Jaws.  Serena looks like she’s really scared too.

If you see a Muscle Butt in the wild, be very careful.  It is an extremely strong and it will put it on you if you try to wrangle it.  Be careful out there.
