This is an Italian historical pic, described thoroughly below:
Italy, 1980s-1990s. With his agency Diva Futura, Riccardo Schicchi revolutionizes mass culture by transforming the hippie utopia of free love into a new phenomenon: porn. Under his guidance, “girls next door” like Ilona Staller, Moana Pozzi, Eva Henger and many others suddenly become world-famous divas and enter Italian homes thanks to the boom in private television and VHS video recorders. The expression “pornstar”, coined at the time, marks the beginning of a new era. The media impact is so overwhelming that it leads to the election to Parliament of Ilona Staller, known as “Cicciolina”, the birth of the Partito dell’Amore and the candidacy of Moana Pozzi as mayor of Rome. The adventure of this big “family” – where jealousies, torments and contradictions explode, the effects of which generate an out-of-control situation in the pornography industry – is told through the eyes of Debora, a young secretary of the agency with a mortgage on her shoulders.
Denise Capezza plays Moana Pozzi and does the best nude scene
Lidija Kordic plays Cicciolina (Ilona Staller)
Tesa Litvan plays Eva Henger
Beatrice Puccilli plays a character named Marcellina

Except Pucilli, all with fake tits (plastic surgery or prosthetics)
Finally a history series I’d watch
