Professor Marston & the Wonder Women (2017)

The origin story of not Wonder Woman, but the Wonder Woman comics themselves, Professor Marston and the Wonder Women tells the tale of the brilliant psychologist behind the lie detector and the DISC assessment - and essentially, the Wonder Woman comic creator's polyamorous life. Marston (Luke Evans) taught at Harvard alongside his brilliant wife Elizabeth (Rebecca Hall) and hired student Olive Byrne (Bella Heathcote) as their research assistant. The three began a permanent polyamorous relationship when the lie detector determined that they were all in love with each other. From it was born the Wonder Woman comics, based on the DISC research and Marston's experience with the powerful women he loved - along with  a touch of sadomasochism, and of course, a little lesbianism. We see plenty of incredibly hot sex scenes from these three, including a threesome on stage and some roleplay that shows off Luke Evans' right rump!
