It seems that Kylie Jenner would like to surpass Kim Kardashian not just in fashion and selfies. She wants her sex life to be “hotter” than Kanye West and KK’s.

Kylie and his beau, the 25-year-old rapper Tyga, went on a post birthday vacation in Punta Mita, Mexico last August 10, Hollywood Life reported. It seems like the couple’s relationship is steaming up.

A source for the site said that Kylie would want her sex life to be more intense that Kim and Kanye’s passionate relationship would appear cold.

“Kylie’s telling Tyga she wants to get busy with him in more countries than Kim’s had sex with Kanye,” the insider revealed.

They also noted that the couple had “hot and steamy” moments during their beach rendezvous.

“They are really enjoying themselves and it goes without saying, their sex life is amazing,” as we quote.

Should their goal be true, Kylie must work hard to top her sister as Kim reportedly admitted that she and her husband can have sex up to 500 times a day, Hollywood Life noted.

As for her boyfriend, Tyga seems to give full support of his girlfriend’s objective.

“Kylie’s so competitive with Kim, but in this case Tyga likes the competition — for obvious reasons,” according to the insider. Tyga is so supportive he coded their intimate relationship as “the International Sex Tour.”

On the other hand, Kim Kardashian is not yet ready to pass the “sex symbol baton” to her younger sister, according to the site. The 34-year old hot mom seems to be making her own plans to stay as the queen sex symbol.

It was previously reported that Kanye advised Kylie to should create her own identity instead of copying her sister, Kim.

Who do you think would reign as the queen sex symbol between KK and Kylie? Let us know in the comments below.
