Stacia and Nate have been working through their trust issues on Married At First Sight, and things get extra steamy during their couples retreat.

In an exclusive clip from the next episode of Married At First Sight, Stacia Karcher and Nate Barnes get playful at the dinner table with the other MAFS couples. Stacia and Nate have repeatedly shown that their physical chemistry sometimes outshines their verbal communication skills. Before their MAFS couples retreat, Stacia and Nate hit a sex shop for some naughty goodies. Production already gifted them a sex swing, but it looked like that was just the toe that broke the camel's back for bedroom accessories.

Nate and Stacia took a moment for interviews before dinner during an exclusive Married At First Sight preview clip, courtesy of KineticTV. Stacia then revealed that Alexis Mitchell and Justin Hall had sex but that Alexis was nonchalant about it. Alexis said she's a "pleaser," so if her husband was pleased, it was a good time, which didn't indicate a great experience on her end. The interview clip set up the rest of the dinner, where Nate and Stacia proved that their love life is staying spicy with a remote and a pair of vibrating panties. As Mitch Silverstein and Krysten Collins shared how they've made amends and that Mitch unequivocally is attracted to his wife, Stacia admitted, "I have no idea what anybody else is talking about." Even today, Stacia probably doesn't remember Mitch and Krysten's positive progress. She added, "There's a lot going on. I'm trying to listen, I'm getting vibrated, and I'm trying to eat." Meanwhile, Nate was coquettishly eating his salad with one hand under the table and one eye on Stacia.

As Stacia squirmed and fidgeted in her chair, the rest of the couples started to sniff out what was happening. Stacia said, "I don't know if he doesn't know how to work the remote or if he doesn't want to know how to work the remote." Nate admitted it was "pretty hot" making her suffer a bit. Alexis got the credit for calling them out, but Mitch was right there with her and asked if there was a remote. Stacia took the opportunity during the reveal to exit the room and sort herself out; Nate followed suit for a quickie off-screen. Sex is definitely a space where Stacia and Nate are evolving past their trust issues.

As the end of MAFS season 15 looms, fans can count on Stacia and Nate's steamy sex life to keep things fun. There's nothing like some vibrating panties at dinner to keep the mood up. Stacia's comfort with them also speaks to the level of trust she is growing with Nate and her sense of confidence in her MAFS community. Stacia speculated that Nate might be taking advantage of the vibrating panties to torture her, but Nate swore he honestly did not know how to turn them off.

Hopefully, the intimate vibes keep flowing for all the MAFS season 15 couples. After so much tension between Stacia and Nate, it was refreshing to see them let loose. Stacia put her confidence in Nate to have fun with their dirty inside joke and didn't get mad when he went off the rails by torturing her a little. It also had an undeniably positive effect on the rest of the group. ​​​
