In the Netherlands, where prostitution is legal, the duo visits Amsterdam's red-light district — touring a sex worker's business and watching a sex show.

Both genders soaking in the same bath? The hosts are in for a surprise when they visit a German spa. They then meet with nudists calling for bodily freedom.

Dominatrixes give the duo an immersive experience in their Berlin BDSM studio, exhibiting the world of domination and submission clients seek as pleasure.

The hosts gear up for a night out in Berlin, the mecca of nightclubs. After a dance, clubbers share their own viewpoints on party culture and sex trends.

The hosts attend a party at Womanizer, a sex toy company — getting rousing device demos and talking with a group of women about female self-pleasure.

The hosts explore polyamory, relationships with more than one partner — diving into two polyamorous relationships, and the unique love that they share.
