Into a room where most of the cast is waiting, Babeta introduces Paul with eyes covered.  His friends welcome him with shouts of Happy Birthday.  He pours champagne and is told there is a surprise coming. This turns out to be Michelle, wearing just pink lingerie and carrying a cake. Paul caresses and strips her, licks icing off her nipples. Babeta joins them to make a threesome, still by the door.

Everybody strips and the orgy starts, mostly keeping to separate MMF groups:

Lucas Lucky, Raul Samworth, Samantha Renton

Louis Murray, Mark Woskin, Vanessa Stevenson

Paul Bird, Mark Woskin (briefly), Babeta Benoite   

Dominik Nicholson, Jim Shaw, Michelle Hatchman

The action is more girl-focused than is usual in US Male productions -- the first MM blowjob starts almost 30 minutes in.  On the plus side, the guys are all fit and cute (unlike the cover girl, Samantha, who nobody could call attractive).  But often they all seem to just be going through the motions, depriving the movie of the heat that made BIrth Day Orgy 1 a winner.

The anal action only starts in the last quarter: Raul tops Lucas, Jim uses a dildo on Louis, and Dominik fucks Paul with a black strap-on -- maybe he's too bored to stay hard...
