The sex scenes in “Game of Thrones” are so steamy that Pornhub is uploading them straight to the fantasy section of its XXX-clip web site — premium-cable giant HBO says in a new copyright lawsuit.

While the show continues to push the boundaries for racy onscreen encounters, its producers don’t want their Emmy-award winning actors featured on the smut site.

“HBO is aware of the issue and is in the process of getting material taken down from Pornhub,” an HBO spokesman told The Sun.

Pornhub decided to explore the world of fire and ice and naked breasts after a report came out last month saying that online porn viewing dropped about 4 percent, or by a million people, in the hour before “Game of Thrones” sixth season premiered a few weeks ago.Viewing levels weren’t back to normal for another four hours.

Data compiled by Pornhub also found that people were searching for the show’s female characters, especially the bleach-blonde dragon-taming princess Daenerys Targaryen played by Emilia Clarke. And it’s no wonder why. Clarke, who nabbed Esquire’s “Sexiest Woman Alive” title last year, has showed a lot of skin throughout the show, including emerging from a burning pyre completely nude in a recent episode.

Searches for Thrones’ leading ladies spiked by 370 percent when the show returned and included fans of Queen of the Seven Kingdoms Margaery Tyrell, played by the stunning Natalie Dormer and Shae, the prostitute-turned-lover of Peter Dinklage’s Tyrion Lannister. Since then, Pornhub has also produced X-rated recreations of multiple titillating scenes from the show.One called “Daenerys Targaryen pleasured by lesbian sex slave in Game of Thrones,” which has already racked up more than 1.7 million views, expands on the Season 1 intimacy lesson Daenerys gets from a handmaiden.

"Thrones" producers have not shied away from showing graphic sex scenes throughout the show’s six-year run including a brothel orgy, a young Daenerys raped after her arranged marriage and the continued incestual relations between Lannister siblings Jaime and Cersei.

It also regularly features full-frontal nudity. At the end of last season, the usually fierce and powerful Cersei, played by British actress Lena Headey, did a minutes-long naked walk of shame — labeit, using a body double. In response to criticism that the award-winning series only showcased female nudity, it featured a close-up shot of a man’s penis before pivoting to a woman’s breasts in this season’s fifth episode.
