Klaus Hobby is clear: Sex! As a single man in his prime, he enjoys it in all variations, as extremes play a major role in his life - including special practices! It's a good thing he encounters some real pleasure-seekers who are happy to help him explore his deepest fantasies: Whether it's anal sex, spicy toys, oral sex, swinger club excesses, or hot games with three, four, or five people, he enjoys sex in every "forbidden" form imaginable. It doesn't get much dirtier than this!.
