Other than porn, I was thinking of other magazine titles that could be on the top shelf.
Five I can think of are:
The Chicken owner's magazines, Your Cock, and Cocks Weekly/Monthly
One for Monkey owners with a similar title (this magazine has great articles such how to teach your Monkey obedience by spanking it, and so on).
The Kitten magazine, Pussies Weekly.
And finally, the Bird magazine, Tits Monthly.
This last title has just launched a new book entitled
'Great Tits and where to find them'.
I'll get me coat! (I'm going to look for Tits!).
