Kross had previously appeared in the February 2006 issue of Penthouse.
"Penthouse was the first magazine I ever shot for," Kross said. "I remember being so nervous and second guessing every pose. Now it's almost as if I become this other person in front of the camera. I feel I really come alive and the photos prove that.
"It is a thrill to be back and to be named Pet of the Month," she said.
Kross can be seen in Adam & Eve Pictures releases "Kayden's Krossfire," "Bree & Kayden" and the upcoming "Kayden Exposed" and "Roller Dollz."
