‘Summer House’ star Kory Keefer bites girlfriend Sam Feher’s thong-clad booty

Summer should be … juicy?

“Summer House” guest star Kory Keefer playfully bit his girlfriend Sam Feher’s butt in a behind-the-scenes video she posted on Instagram Monday.

The couple matched in risqué caveman outfits at the cast’s jungle-themed Labor Day party as Keefer lifted up Feher’s brown mini skirt and put his mouth on her right cheek.

Feher seemed to enjoy the playful display of affection, as she held her arm on Keefer’s back while he smiled and laughed afterward.

“???? #summerhouse season finale tonight at 9 PM ET on @bravotv,” Feher, 25, captioned the post.

Keefer, 32, commented, “That was my only meal for the day.”

The influencer posted another series of PDA-packed photos that included her and the gym owner touching tongues as well as a video of her straddling him while making out by a pool before he pushed them both in.

Both Feher and Keefer have spoken candidly about their sex lives, having immediately bonded over their love of biting and spitting into their significant others’ mouths.

The “Winter House” star even recently divulged on Page Six’s “Virtual Reali-Tea” podcast that the first time they had sex was on a beach in Montauk last summer.

“It was kinda weirdly romantic,” he gushed. “It was such a good vibe. It’s funny, so we hooked up … our first time, like, officially sealing the deal, was on the beach.”

Keefer added that even nine months later, the “sexual tension is 100 percent there.”

“It just kind of was like, ‘OK, we are romantically compatible.’ Because sometimes, too, like, she said, ‘You can get the ick after you hook up,’” he said. “And you’re like, ‘Ooh, that wasn’t what I liked or was kind of weird.’ That 100 percent was not the case.”

Feher confirmed to Page Six exclusively last month that she and Keefer made their relationship official after meeting on “Summer House.”

“Kory’s my boyfriend!” she eagerly spilled on April 4. “That is so weird. I haven’t had a boyfriend in so long!”

The entrepreneur teased at the time that fans would be able to watch the pair’s “love story” unfold at the end of the reality show’s currently airing seventh season.

“I don’t want to get emotional, but it’s very special to find someone who means so much to you and then get to relive that experience all the time,” she told us.

“Summer House” airs Mondays at 9 p.m. ET on Bravo.
