Kim Kardashian, Kanye West get hot and heavy in 'Bound 2' video

If you're wondering what a "lite" Kim Kardashian-Kanye West sex tape would look like, look no further. 

The overly exposed couple cheekily simulate coitus in the rapper's latest music video, "Bound 2," which he debuted Tuesday on "The Ellen DeGeneres Show."

The slimmed-down reality TV star appears in the video not only to show off her enviable post-baby body, but also to straddle her fiance as he rides a bouncing motorcycle. Two more things: She's topless, and she's straddling him from the front as they "ride" against an ever-changing scenic background.

Shouldn't someone be wearing a helmet? Or clothes? 

The 33-year-old mother of his child, North, is silent in the video and appears only to pose, tousle her hair or stare silently at the camera. Soon after the video debuted, the "Keeping Up With the Kardashians" starlet posted the uncensored version of the video on her blog and YouTube page.

While most celebrity couples shy away from PDA, these two are just lapping it up and they seem to favor that particular position ...

The rom-raunch video was directed by Nick Knight and West, the self-proclaimed "creative genius" (but don't ask him to spell it). The rapper told DeGeneres that he doesn't believe his profanity-laced work or video should come off as "dirty." 

"No, I'm not as concerned with the idea of profanity or nudity; it's more the messaging behind it," the 36-year-old said. "[North is] going to be in the real world, so she's going to hear things and see things. I think she's going to be prepared for that."

The "Black Skinhead" rapper also gushed about about his elaborate proposal on Kardashian's 33rd birthday for which he rented out AT&T Park in San Francisco for a private gathering to ask her to marry him.

"I just think Kim is awesome and she just deserved an awesome moment like that," he admitted sweetly.

"She's an important person; when I was at my lowest moments I could get on the phone with her and she would make me feel like, you know, I was here for a reason. And I had something to say and support me through that.

"I mean it's incredible to have a woman like that, that you know is not using you for money, I just have to word it like that because once you become a multimillionaire there's a certain type of woman out there that they go for that and they'll put on the whole act and everything. But to have someone that has their own ....

"Her personality is so calming. And I don't know if that's the way people would describe my personality," the rapper added, alluding to several of his volatile public altercations.

West, who is currently promoting his critically acclaimed "Yeezus" tour, also described the former sex-tape star as his "dream girl."

"People make fun of me for how in love I actually am. And people are just so cool with their approach to things, and also I'm trying to avoid the jump-up-on-the-couch moment," he laughed.

As for ending up with baby North, DeGeneres asked him if she was planned. 

"We were just practicing all the time," he laughed. "And practice makes perfect."
