Kourtney Kardashian is the queen of risqué this week — first she was sucking on Travis Barker’s thumb for the ‘Gram … now she’s openly asking the public about rough sex.

KK posted a very racy pic — a photo of a stock image that captures her lower half of a woman, unbuttoned and fairly exposed near the groin area. A belly button and white panties are exposed, which have “Oui” embroidered right on the front … and in red, no less.

On top of that, there was a question she posed to her followers — “ROUGH SEX: LOVE IT OR LEAVE IT?” So yeah, it seems like she’s answering her own question a bit here. But also, she’s continuing this recent streak of not leaving much to the imagination.

We’re not clutching our pearls here — just noticing a trend carrying over from the weekend. You’ll recall, Kourtney’s BF, Travis Barker, posted a video of her sucking on his thumb … which looked like something else at first glance. Either way, it’s been PDA times 10 lately.

Speaking of being cuddly in public … Kourtney and Travis were doing a lot of that as well over the past few days — this after Kourtney turned 42 and celebrated her birthday. They were spotted out at some beaches in the OC … and on both occasions, getting cozy.

They weren’t shy about it either … with Travis grabbing himself a handful while laying out on the sand, and later posting a pic with Kourtney laying on top of him — derrière in full view.

Don’t get us wrong or anything … it’s good stuff. Maybe too much good stuff, though, at this point.
