Any title that plays off semen gets props for making us laugh. Unfortunately, there's not much else going on here to get viewers' mouths moving, as a bunch of Czech fellas aboard a riverboat engage in some standard sex. These five scenes (four in truth, as the first ends in the middle of nothing) are hard to distinguish from each other, and it doesn't help that a lot of the sex isn't even visible through questionable camerawork (watch for the opening blowjob in the third sequence and you'll understand. What? You can't see it? Exactly...). Shiver our timbers and blow us down... these seamen need some help.
