Bigger-Than-Ever Rob Kardashian Makes Vile Sexual Request To Mom Kris

Rob Kardashian is officially back on the scene and acting more inappropriately than ever before!

In a new Snapchat posted by sister Kourtney on Monday, the 29-year-old got a little too candid with his momager, Kris Jenner.

"There's something so wrong with my brother, I just want you guys to know that," Kourtney says in the clip, as Rob drives with their mom on speakerphone.

"Hey, Mom," he then hollers with a sneaky smile on his face. "Why don't you shove your d*ck in my mouth?"

"Yeah?" Jenner answers soon after, clearly befuddled by her only son.

Meanwhile, as RadarOnline.com previously reported, the reclusive star and his baby mama, Blac Chyna, have been on the rocks since they started filming Rob & Chyna.

During production for their show, the overweight Kardashian sibling allegedly got a hold of Blac's phone and found proof that she had broken their trust.

Although sources told RadarOnline.com the dustup was all made-for-TV drama, the insider said that now, "Rob insisted to Blac that, from now on, he must always have the password to her phone! In addition, Rob told her that she must hand over all over her passwords, including her email."

Even worse, "He also thinks that Kris should be in control of all of their finances from now on. But that's not a given yet. Blac Chyna obviously agreed to most of his terms," said source, adding, "she will do anything It takes to stay with Rob!"
