Don't be fooled: March 2008 Penthouse Pet of the Month Bree Olson (above) may look like a normal very cute teenage girl, but she's already demonstrated a very sexual side in numerous porn videos.  If you've seen Bree in action, you know she has a very vocal and enthusiastic onscreen persona.  But this month we can enjoy her slightly softer side, in the sexy photos and videos she's created in partnership with the folks at Penthouse.  Here's a free preview of Bree's centerfold pictorial - with much more to see from that set and several more, including a hot hook-up with February Pet of the Month Cali Taylor.  Much more of Bree coming this month to Penthouse.com.

More Euro-babe goodness in the March issue of Penthouse, this time a sexy photo set featuring beautiful Gina Novak.  If you're a fan of the nude models of eastern Europe, you may know her as Gina, Denisa, Danae, Dana or even Heather Wild.  Whatever name she's going by, she always looks fantastic.

Two girl-girl sequences fill out the March edition, with Sammie and Charmane getting friendly in "Show Girls" and Diana and Marie displaying some affection in "Blonde on Blonde".  Yes, they're both blonde.

Sammie and Charmane can also be found on the cover of the March 2008 Penthouse, kneeling at the feet of brand new 2008 Penthouse Pet of the Year Erica Ellyson.  We have a feeling Erica could get us on our knees, too.
