Kourtney Kardashian chased Scott Disick around the house while wearing a strap-on dildo on the June 2 Season 8 premiere of Keeping Up With the Kardashians.

The June 2 return of Keeping Up With the Kardashians was full of TMI moments. Early in the episode,  Rob Kardashian admitting to having anal sex with two different women, which piqued Scott Disick's interest. The father of two then presumed that Khloe Kardashian and Lamar Odom have "backdoor sex" often and urged a disgusted Kourtney Kardashian to try it. "I'm not a backdoor betty," she told him.

"If I keep knockin', that door's gonna open," Disick said with a smirk.

The father of two didn't give up easily, and he sent his girlfriend a crude joke via text message. "Knock knock, who's there?" he asked Kourtney. "It's my penis knocking on your back door." Khloe then suggested that her sister give Disick a taste of his own medicine by asking him to try it first.

When Kourtney presented the idea to Disick, he dismissed the idea. "This is not a two-way street!" he said. He later relented, telling his partner, "I'm going to call your bluff."

Later in the episode, Kourtney snuck up on her boyfriend -- while wearing a strap-on dildo over her pajamas! She then chased Disick around the house before he agreed to never bother her about trying anal sex again. "I think I may have to become celibate after this," Disick said.

Keeping Up With the Kardashians airs Sundays at 9 p.m. EST on the E! network.
