Travis Scott's been smashing (and possibly using) Kylie Jenner for a bit now.

But did you remember he also used to have a thing with her older sister Kendall?

Well, he did. And, apparently, he's been comparing how the sisters are in bed.

"He’s been boasting that Kylie’s way better in bed than Kendall and has more to play with," an insider told OK. "But Kendall’s got more personality.”

That same source also told the gossip rag that Scott's real intention is “trading up” to Kourtney Kardashian because his goal is to go through the entire extended Kardashian family.

Now Kourtney would be an impressive get for LaFlame, as the oldest Kardashian isn't traditionally as Hip Hop friendly as her younger sisters.
