Last week, we showed you a preview of Kim and Khloe ganging up on Kourtney after stalking and spying on her, crossing so many boundaries.

Now, we've seen the context. Kourtney was upset at the violation, and Kim's response was that Kourt should be fired from their family's show.

As you can see early on in this Keeping Up With The Kardashians clip, Khloe spied a hickey on Kourtney's neck.

When Khloe tried to extract answers from her, Kourtney -- though clearly blushing -- pleaded for her to "just let me live."

Obviously, Khloe and Kim weren't about to let things go that easily.

If Kourt wasn't going to tell them what she's up to, Khloe and Kim resolved to play amateur detective and find out for themselves.

For her part, Kourtney told her sisters to not "worry about it," because it was her business.

"My sisters are pretty nosey when it comes to anything in my life," the eldest complained to the konfessional kamera.

She continued: "And I try to keep certain things private."

"I don't like to share about, you know, dating," Kourtney noted. That's fair enough.

"Kourtney having a hickey is like, wild to me," Kim admitted to the camera.

And it's not just because she's a 40-year-old woman and not, you know, a 15-year-old high school student.

"I had no idea she was even hooking up with someone," Kim acknowledges.

It looks like Kourt and her alleged mystery someone have been having a good time.

"Wait, she's in her Astin Martin," Khloe points out as she and Kim watch Kourtney pull out of the driveway.

Even those of us who know absolutely nothing about cars know that these are expensive and associated with James Bond.

Khloe excitedly exclaims: "That's the ho-mobile!"

Clearly, if they see Kourtney driving that particular vehicle, they expect that she's ready to bone.

"I kind of feel like an a--hole following Kourtney," Kim admits to the confessional camera.

"But early on we all made a pact to share our lives," she reasons. "That's our job"

"Kourt spends a lot of time off camera and won't talk about her relationship," Kim complains.

She continues: "But you'll see paparazzi photos of her and her guy."

Kim and Khloe tracked Kourtney to what they perceived to be a random house.

They snuck around to the back, which sounds like trespassing, and also "armed" themselves with someone else's outdoor stuff?

Like ... following Kourtney to snoop into her business is not the only boundary that they crossed.

Obviously, Kourtney came out and was pissed that they were stalking her, but Kourt's angry reaction just made the sisters more frustrated.

Kim consulted a fan report that concluded that Kourtney hides more of her personal life than Kim or Khloe.

"I'm not surprised that the report says that people don't feel like they know the real Kourtney," Khloe admits.

She explains: "'cause sometimes I don't think Kim and I know the real Kourtney."

Kim went so far as to call Kourtney and threaten her with firing for keeping things private.

"We have a proposal for you," Kim threatens over FaceTime. "It starts with an f and ends with a d."

Kourtney hit back while speaking to the camera: "If Kim thinks she has the power to fire me from our family show? It's just crazy."

"It's just sometimes we need a break and I don't want to film with Kim," she explains.

They had a family meeting on their huge comfy "couch" made up of multiple beds lined up.

(Side note: they are always so fully dressed for these talks and it's so weird; they're even wearing shoes indoors! What is this, the Purge?)

Kim tries to pressure Kris to pressure Kourtney to air her sex life with the world.

In the mean time, Kourtney insists that she does not have a boyfriend and is not dating.
