THIS is the comical moment when two skinny dippers receive quite a surprise after leaping into what they thought was a “private pool” – only to realize they aren’t by themselves.

Karina Horton, 24, and her friend Bella, 20, stripped off for a dip after treating themselves to a villa stay during their travels.

They were travelling around Bali, Indonesia, but decided they needed a touch of luxury along the way – so booked this modern, white-walled haven.

Upon arrival at 6am, the women immediately ditched their clothes and threw themselves into the water to cool off.

Believing themselves completely alone, the pair were stunned when a man emerged from his room to see what was going on.

The villa turned out not to be private at all.

Amusing footage shows the women splashing and swimming in the rectangular pool, making the most of their retreat.

Suddenly, Bella spots the onlooker off camera and shrieks to alert Karina.

The pair sheepishly wave at their unexpected guest as he hangs around to make small talk.

A male voice can be heard saying: “You woke me up, where are you from?”

They answer “Australia”, before waiting for him to leave.

They climb out of the water after he has retreated and hastily pull on their towels.

The travellers shared their hilarious slip-up on TikTok, where the video has amassed 20million views.

Karina said: “We were expecting a private villa, not a shared one.

“We wanted a swim in the pool after a hot travel day.

“Then we jumped in, and a man came out of his room.

“We were shocked and surprised, but we then looked online and realised it wasn’t advertised as shared or private.”

The clip is captioned: “POV: we thought we booked a private villa but when we arrived at 6am we soon realised…”

Karina also shared some advice for her followers: “Pro tip: check your villa is shared or private.”

Karina, a photographer, and Bella, a business owner, from Australia, added: “We are young and adapted to the setting fast for our safety.

“But to other travellers, check the room option photos and details.

“Not just the overall accommodation, as you never know what room you could get.”

The clip has gathered 1.7 million likes and over 700 comments from users on TikTok.

Kennedy added: “Skinny dipping as soon as you get there is crazy.”

The pair were travelling in Bali, Indonesia.
