Each week we select one of the most popular models on the web to feature as our "Babe of the Week". Whether she's calling herself Nikky Case or Nikki Case or Irena G, this week's BOTW is one of our all-time favorites. Nikky doesn't hesitate to take advantage of her natural beauty, often working without the benefit of make-up - and looking perfect every time. Regardless of nationality or profession, Nikky is one of the most beautiful women on Earth and it's beyond amazing that she chooses to show every inch of her beauty all over the web.

Before we knew her as Nikki we were drooling over stunningly gorgeous "Irena" at one of our favorite Euro-girl sites, TeenDreams. It was pretty obvious from the first nude Irena photo set that she was something seriously special. She's devastatingly hot in everything she does, whether she's getting out of a hot bikini or lounging around naked poolside. We even get to see Irena doing the hardcore lesbian thing with other hot models! Thanks to the fine folks at TeenDreams we can even share a couple of preview videos of Irena getting nude and naughty. But that's just a taste - they have 31 enormous photo sets and 4 full-length movies featuring Irena's perfection. (If, for some strange reason, you don't want to see all the other hot models at TeenDreams, you might want to check out SweetIrena.com, where it's all Irena, all the time - from super-hot solo photos and videos to her most explicit girl/girl material!)

Probably the sexiest thing we've seen starring Nikky is the sexy three-part video called "Pretty Pink" that she did for Penthouse.com. Just Nikki quickly getting out of her little pink outfit and spending the next 15 minutes pleasing herself - and anybody lucky enough to be watching. And it's available in excellent hi-def format! Easy to understand why it's been voted the best solo girl video by Penthouse.com members.

But that's still not enough for true Nikki/Nikky/Irena fans: they absolutely MUST also take a peek inside Met-Art.com, where it's Nikky Case nude in a luxurious bed, Nikky Case doing a retro '60's nude photo set, Nikky Case naked on an enormous tractor...well, you got the idea. Lots more Nikky at Met-Art.

Still want more? Okay one more: The folks at Teenrotica.com specialize in very sexy photos and videos starring young ladies from Europe. They have some excellent photos of Nikky showing off her lovely pink bits.
