Taylor Vixen (above) is featured as the 40th Anniversary Penthouse Pet of the Month. Taylor isn't exactly the kind of glamorous babe you might expect for such an "auspicious" occasion, but she does have plenty of natural, girl-next-door charm to share.  You aren't likely to give her the boot for the adding the proverbial crumbs to your bed.  Our one complaint is that the photos of Taylor in the magazine are ridiculously small.  Fortunately, they're all available (with plenty of extras) in much BIGGER size at Penthouse.com.

Also along to celebrate are former Pets Aimee Sweet, Andi Sue Irwin and Julie Strain.  We've never been big fans of Julie, but Aimee and Andi Sue are as gorgeous as ever.  All are in great shape 11-17 years after their first centerfold appearances.

Fans of UK babe Gemma Massey can also celebrate with her hot new photo gallery in this month's Penthouse.  Gemma spent a lot of time on her back for this photoshoot, which is nice.

And it wouldn't be a 21st century issue of Penthouse with some girl-girl goodies.  This month there are two girl-girl pictorials plus a girl-girl-girl extravaganza, including uber-hotties Georgia Jones and Jayme Langford.
