Malibu has become Temptation Island ... because we've learned 17-year-old Kendall Jenner and her 15-year-old sister Kylie Jenner have set up a house by the sea -- where clothes are kept to a bare minimum.
Sources close to the Jenner sisters tell us, the Kardashian fam is renting a palatial beach pad primarily for the two girls during the summer months -- and no doubt, the hormones are going nuts.
You'll recall, Kylie is currently dating Will Smith's son Jaden ... and Kendall's obviously got her own endless list of suitors.
But there is a small catch -- we're told one of their parents (either Bruce or Kris) has to be present in the house at all times because the girls are minors ... but as far as parentals go, they're both pretty hands-off.
Bruce has been the one with the assigned duty and that's why he's been living in Malibu lately -- not a bad gig.
