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 at home, where a sailor's big fat rope needs his attention. Meanwhile on board everyone's got their trousers off, having a good time in the bunks. On deck those masts are given a good scrub and the only thing that is going to cool these hot pistons down in a dive in 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!
