She captioned the post: "Cheers to forever" along with a slew of emojis.
In the series of photos, the pair are seen getting a little frisky, with Barker latching on to Kardashian's foot and giving it a bite.
In another photo, Kardashian poses with a bottle of champagne while Barker kneels beside her, attempting to bite her garter off.
Kourtney and Travis were married for a second time at Castello Brown, a castle they rented out in Portofino, Italy. The occasion took place on May 22, and saw the pair stand at the aisle in outfits designed by Dolce & Gabbana.
Kourtney wore a custom bridal minidress, and during the ceremony, donned a trailing hooded lace veil with the Madonna sewn across the back.
The veil is spotted in closer detail in a series of new photos shared by Barker, which capture the pair in an elevator.https://www.instagram.com/p/CeFB2C1vLeo/
Captioned "Love in an elevator", the pair are shot getting cosy in the elevator, also wearing their wedding outfits, and sharing a kiss.
These photos have sparked baby rumours for Kardashian, given in the last photo she is seen holding her hand to her stomach.
"Oh yeah, she's pregnant," commented one user.
"Is that a baby bump?" another speculated.
But many don't think that's the case.
"I don't think she is," one person wrote. "She jumped off the boat after they got married in Italy…I wouldn't think a pregnant woman would do that, especially one that would be considered high risk."

Kourtney has been open about her tough journey with IVF, which she says has led to weight gain and "hasn't been the most amazing experience."
The mum-of-three, says she wants a baby with her new husband Travis Barker, but at 43 is finding it a little more difficult to conceive.
Recently, an insider told People: "It's been an emotional rollercoaster."
"They never expected it to be as hard as it's been. It's been especially difficult for Kourtney. They still would love to have a baby. Travis is not putting any pressure on Kourtney though. He just wants her to be happy and healthy."
