E!’s expectant stars Kendra Wilkinson and Kourtney Kardashian are showing off their bumps together on the latest cover of Us Weekly.

Only E! News was behind the scenes of their cover shoot, where the moms-to-be grubbed on Burger King and dished about their sex drives, breast-feeding and birthing.

“I’ve been hornier!” Kendra told the mag of her sex life with hubby Hank Baskett at their shoot. “We’ll be off-roading, and we’ll go at it in the bushes somewhere! Or we’ll be driving, and he’ll pull over. Quickies are the best! If he lasts any more than a couple of minutes, I’m like, I’m done!”

Both of the former party girls say their men will be in the delivery room when the big moment happens, but they’re not sure if they’ll watch…

“At first he said, ‘I’ll be there next to you but won’t watch.’ But now he says, ‘I want to see the crowning moment.’ I’m like, ‘Will you have sex with me after seeing this?’ ” Kendra told Us.

In case you’re wondering, both ladies hope to deliver their babies naturally and want to breast-feed, despite their implants.

Once the baby is here, Kendra says she’ll have no qualms about taking her little one to visit the Playboy Mansion.

“Hef is a huge part of my life, and I don’t care about any other whore there,” she told the mag in her typical candid manner. “I care about Hef. He’s a good dad, a great person, and I want my child to be around him a little bit.”
