"I had done solo for a couple of years, and I decided 'Why not?' I'm already in the industry. If I'm going to do it, I might as well do it all the way," Hilton told XBIZ.
Shooting the scene was different from her usual solo work, Hilton said.
"It was different, because it wasn't just about me. It wasn't just posing. It was harder and more work than I thought it would be. But I had a blast.
"It was easier than a regular photo shoot. A regular photo shoot, I've been on set for 12 hours. It's actually cool to get right in and get right out."
The scene was shot in a gym setting, and involved "really heavy sex," Hilton said.
Hilton also said that she will do more b/g scenes. "I'm not sure when or for who yet, but I'm definitely leaning on doing more — probably within the next couple months."
Previews of the scene are now available to subscribers on the Brazzers website Real Wife Stories.
