There is only one girl, and she is obviously a pro, and Bob obviously is not. The beginning is long and boring. Once they get back to Bob's it gets better (barely). Bob practically blows his load before she gets his pants off. Should have been called Tubby-Gump. This is good for a laugh, but not something you want to stroke to.
This was just an unimpressive collection of scenes that appeared to be thrown together from other films. Most of the women were unshaved, and unattractive. Might be good for one jerk, but that's all. Plenty of better movies out there.
None of the Euro girls were all that attractive. Sex scenes were oddly cut. On minute the guys are getting blowjobs, and the next, it cuts back to them taking their clothes off. Poor editing. First scene ends with the girl pissing on the ground.
