Following her ever-long Italian vacation, the 39-year-old mother of three reunited with her sister to have a family Taco Tuesday night. Kourtney took to Instagram Story to share a pic of their kitchen, which was filled with all the taco night necessities.
Khloe, 34, also posted a couple of videos on her page from their dinner date, which included her hugging Mason.
"Hi Mase, what do you like most about Taco Tuesday?" Khloe asks Kourtney's eldest in the first clip. "Nothing. Playing Fortnite," he replies. In another video, Khloe continues to hold Mason while she and Kourtney dance around in the kitchen.
"Are you lost at sea?" Khloe wrote on one of Kourtney's fabulous bikini shots, before adding a second comment. "I come back in town and you leave the next day. Should I catch a hint?"
Kourtney replied to her younger sis, "Be nice or I'm not coming back."
The brunette beauty, however, did return on Monday and spent the day with Khloe and her adorable baby girl, True. She couldn't help but gush over how cute True was, posting an Instagram Story video and captioning it, "I want to suck her cheeks."
