Just like when her sister Kim Kardashian starred in husband Kanye West's music video in 2013, Kylie Jenner is her rumored boyfriend Tyga's muse in the new music video for his song "Stimulated."

While they have been careful about not displaying too much PDA for the paparazzi, Kylie and Tyga are all over each other in this NSFW video.

As for the song itself, "Stimulated" includes lots of R-rated, NSFW lyrics that appear to be about his relationship with Kylie. In the song, Tyga raps about having sex with a young girl. Kylie just turned 18 earlier this month.

"I'm stimulated / I'm at the bank, I'm penetratin' / I'm puttin'in, I'm penetratin' / I'm gettin' big, she stimulated," Tyga says. "They say she young, I shoulda waited / She a big girl, dog, when she stimulated."

He continues, "F**k what they talkin' about, I do what the f**k I wanna do."

The highly sexual lyrics don't stop there.

"She a big girl, dog / I’m puttin' in, yeah, I'm penetratin' / I'm getting big, yeah, I'm stimulated," raps Tyga. "Might take her home, gonna dinner plate it / I don't heat it up, I don't microwave it / She already hot, she sizzle, baby / No salt-n-pepa, she been the flava / Ima stimulate her."

On the same day as the release of the video, Kylie and Tyga were seen at the 2015 MTV Video Music Awards. They were also later spotted holding hands outside a Republic Records private post-VMAs party.

Over the weekend, ET sat down with Kris Jenner and asked her point blank if her daughter is dating Tyga. The momager played coy, quipping, "What time is it? I think we have to go!"

Regardless of what Kris is willing to admit, Tyga and Kylie are certainly an item in this new music video!
