Vintag porn: Gym sex
The name of this wonderful The Mans Best Title is "Fickness Center" (many thanks to the GPT friend who let me know) and 'Fickness' can be translated as Fickleness meaning - unstable, unpredictable, or constantly changing in loyalties, affections, or opinions. It implies a capricious nature, often used to describe moody people, shifting weather, or volatile situations - I leave to you to decide how that fits this wonderful bit of 1990s porn set in a gym which starts with a bevy of mostly blond beautiful boys exercising on the machines who are consumed by lustful thoughts, which leads to lustful actions as they strip off their own, and each others, gym gear and get down to pounding on each other using some unorthodox muscles.
It would not surprise me if this film is by Rolf Hammerschmidt - certainly many of the boys who appear in it also appeared in films made by him like 'Internat 1900' parts one and two and his early 'Heisse Auf Eis' or 'Hot On Ice' - his films always featured beautiful (over 18+) boys in films with plenty of sex but also great stories.
