Netflix series with ‘hot sex scenes’ crashes most-watched charts as it’s binged for 56.9 million hours

A raunchy new Netflix series is so gripping that it's got viewers staying up all night to watch.

The 18-episode series caught people's attention not only for its steamy love-making scenes, but for its rollercoaster plot packed with twists and turns.

Having been released on July 30, the show shot to the top of Netflix's global TV charts, racking up 56.9 million hours viewed, according to FlixPatrol.

The story centres on Helena Rivas (Zuria Vega), a woman trapped in an abusive and controlling marriage to wealthy businessman Claudio Martínez (Erik Hayser). In search of escape, she begins a passionate and illicit affair with Iván Díaz (Who Killed Sara? Andrés Baida), a younger man and escort.

Their romance soon turns dangerous as they try to blackmail Claudio using a sex tape in an attempt to free Helena from their loveless marriage.

Only, events spiral out of control, and Helena learns there's much more to her husband than she could have ever dared to imagine.

The series climbing the Netflix charts is Unspeakable Sins. Described as 'top tier' by some fans, it's earned a modest IMDB score of 5.8.

"I was hooked watching it all day and all night," one fan wrote. "I recommend it for people who love suspense. The next thing you know you're not sleeping in the name of watching the show."

A second echoed: "Lots of unexpected twists and turns. Some very tense moments. Strong characters each with their own story and motives so it's definitely not predictable." Another social media user hailed it 'gripping,' saying the show delivers 'exactly what it promises.'

Of course, there's no avoiding the show's lengthy - and sometimes misplaced - sex scenes.

Decider recommends streaming the show if you're in it for the 'sexy stuff,' explaining: "This is the kind of show that you watch if you want to see lots of hot sex scenes, usually cued up with what the subtitles always call 'sultry music,' and see if the good guys... win."

For some, though, these steamy movements proved too much.

One viewer reckoned they were 'poorly placed,' as somebody else slammed it as 'another soft-porn TV series where the story and message get lost within the over-exposed sex scenes'.

Others took it all in good faith, however. "Yeah the shirtless men and sex scenes are a lot for some people, but I found it fun and entertaining," one person said.

All 18 episodes of Unspeakable Sins are streaming now on Netflix.
