AceShowbiz - Kourtney Kardashian has been enjoying her vacation in Italy with Younes Bendjima since last week. The mother of three showed off her amazing figure in a sexy one-piece swimsuit while soaking up the sun and relaxing on a private yacht on Tuesday, July 3.

The "Keeping Up with the Kardashians" star teamed her look with a wide-brimmed Panama hat and a pair of sunglasses as she flaunted a huge amount of her sideboob. She had her black tresses in a sleek ponytail. Meanwhile, 25-year-old Younes was seen topless while donning patterned shorts.

Joining the lovers at that time were Kourtney's three children, Mason, Penelope and Reign. She was seen goofing around with her eldest son before heading down to the ocean to enjoy a dip in the crystal-clear water. Another photo saw the socialite looking out into the sea with five-year-old Penelope, who rocked a green one-piece bathing suit.

Even though paparazzi photos from her yacht date have already circulated online, it doesn't stop Kourtney from posting the pics herself. She took to Instagram to share a couple of pictures with her model beau aboard the yacht. "Ride with U," she captioned the pics which featured her posing with binoculars.

The sexy swimsuit was one of the stylist ensembles that Kourtney has rocked throughout her Italian vacation with Younes. She previously risked nip slip in white off-the-shoulder mini dress which paired with tiny white-framed sunglasses and simple white slides. She didn't seem to be flustered as she held the dress to prevent it from exposing her privates. Kourtney also went daring in a Jacquemus dress with a fringe skirt and strappy heels.

Kourtney and Younes began their romantic vacation by visiting Rome, where they went sight-seeing as well as enjoyed dinner and coffee dates. An onlooker reported that the pair looked happy, smiling and laughing during their stroll in the city.
