Water Rats(2008)

A voyage at sea can splash it and squirt it all over you. Andreas wants to take a hot excursion on Berlin's waterways with some of his mates. Felix unfortunately isn't sea worthy because he's tied up and home, where a sailor's big fat rope needs his attention. Meanwhile on board everyone's got their treasures off, having a good time in the bunks. On deck those masts are being given a good scrub and the only thing that is going to cool these hot pistons down is a dive into the lake. After all this hot summer action, Andreas isn't allowed to take a break. He has to deal with a cheeky nocturnal burglar and give him a good hammering. Then the only thing that's going to be stolen here is sperm and plenty of it.
