Potm. Now We Know Why. Yes, it is really Lanni Barbie, Penthouse Pet of the Month! Here she is getting a pounding and loving it. This girl is one of the truly hottest girls out there...one of only 12 girls a year to be called POTM! She fucks and sucks like a banshee too! And that pussy is as good as it looks and tastes. My question is where the fuck do I go from here. Once you've fucked the snot out of a POTM what do you do now?
