Kristen Stewart and Love Lies Bleeding costar Katy O'Brian put on a steamy display in a new photo shoot for the online LGBT magazine, Them, which launched in 2017.

The actresses, whose characters Lou and Jackie fall hard for each other in their sexy new action thriller, which hit theaters earlier this month, looked smitten as they got frisky with one another on a couch in a makeshift music studio in Altadena. 

In one image, the Twilight star, 33, posed on top of the Indianapolis native, 35, while rocking a loose red t-shirt and blue boxers. 

She brought her face right next to O'Brian's as she grazed the bottom of the actress' lips with her fingers. 

Another picture showed them both laying in a bed with several shirtless women and men around them. 

While reflecting on the photo shoot, Stewart raved that she had 'been wanting to do this photo shoot for the last 15 years.' 

While speaking about their recently-released film, O'Brian said what she loves most 'about this movie is that the queerness isn't the conflict.'

'It's the type of film that I, as a queer person, would want to watch — to not have drama around my sexuality, and to just admire these two absolutely wacky individuals,' she explained. 

Stewart proceeded to speak about their love scenes, which she said were aimed to not be 'about [showing] simulated sex on film.'

'I'm so embarrassed by that. I'm so sick of watching it. I'm so sick of doing it,' she noted. 

For her, the actor reflected on preferring the more subtle ways of acting out intimacy. 

'The ways that you let the person you're with either take over or be consumed,' she explained. 'Those were choices, and they were very articulate, yet nonverbal decisions that we made together. And without that dynamic, nobody would have cum.'

She continued: 'Literally, you could almost take the body out of it. You could tell me the right thing, and that's what's going to get me there. Tell me I am something to you. Tell me I can be taller than you, even though I'm 5'5', and you're fucking 5'10', and I'm there.' 

Over the weekend, O'Brian admitted that their 'horny sex scenes' did not 'feel as sexy in the moment' during an interview with People. 

'We're filming in Albuquerque. It's hot, it's in the summer — it's like 112 degrees,' she explained. 'So we feel sweaty and gross, and we just hope that we're not stinky and everything,' adding, 'It doesn't feel as sexy in the moment.' 

And while the coupling may look intimate on screen, in reality the actors were surrounded by crew members. 

'It's just so not glamorous, and it's really not that sexy when you're doing it,' she maintained.

'I mean, first of all, you've got a boom-mic guy that's got his microphone hovering over you while it's all happening.' 

 Director Rose Glass, who joined in the interview, agreed.

'You're usually worrying more about something like the camera falling on the actors and killing them and hoping that doesn't happen, and forgetting the fact that, oh yeah, they're simulating sex.'

And while their actions on the big screen may look spontaneous, each move is choreographed and agreed to before the cameras begin to roll. 

'We stick with the script for those scenes, because with intimate scenes there's massive approvals that go into everything.'

'If anything changes,' she said, 'we have to go back and sign more paperwork. We just had to approve it all ahead of time.' 

Intimacy coordinators Christine McHugh and Rebekah Wiggins made sure privates were protected by using modesty garments during the simulated nude scenes.

Some were similar to the garment John Cena wore when he presented the Best Costume Design award at the Oscars. Others were put together on the set. 

'Our intimacy coordinator wanted to make sure I had lots of layers between me and Kristen, so she would tape down one layer of fabric, especially in our first bedroom scene, where you have to see the side of me, so we can't have underwear on,' she said.

'I think there was another layer, and there was literally a cut-out yoga mat that she put over me, and taped that down,' she added. 

There was one incident in which the sweaty conditions created a mishap in a scene, in which Stewart was supposed to remove O'Brien's pants. 

'It was so hot that every time Kristen would pull the pants off, everything would just pull right off. So finally we're just like, 'Can we just do this with one layer? Do we really need a diaper?' the actress asked. 

For her sex scene with co-star Dave Franco, the intimacy coordinators used a 'deflated yoga ball' as 'a buffer.'

'There was some funny little experimenting with protection,' she said with a laugh, adding, 'It just felt really not sexy and very silly.'

Love Lies Bleeding is in theaters nationwide after opening in a limited release.
