Brazilian postal workers have confused this cute dog toy for a sex aide after it arrived at the post office and began vibrating inside the packaging.

In a viral post viewed more than 4 million times on TikTok, Adriana Sirotenco, 45, from the Brazilian state of Sao Paulo, explained that she ordered the dog toy from the online store Shopee for her Pomeranian named Simba.

However, she was not at home when the postman came knocking and was instructed to collect the item at the post office.

When she arrived, a post office worker instructed her to go to the furthest window from the rest of the customers as they suspected she was there to collect a sex toy still vibrating in its packaging.

Adriana said: “The attendant told me I didn’t have to queue and could pick it up directly. I thought ‘that’s strange, but fine’.

“When the attendant came back with my order, it kept jumping about on the counter. There was another worker behind her with an embarrassed look, wanting to laugh.

“I, feeling embarrassed because they obviously thought it was something from a sex shop, opened the box at the time to show them what it was.”

Adriana can be seen bashing the toy in its packaging which sets it off in a vibrating frenzy.

A second clip shows her fluffy Pomeranian playing with the blue toy as she cracks up laughing.

She told local media that she was left stunned by the online reaction to the footage, explaining: “After a little time passed, I saw that it had ‘10k’. I didn’t even know what that was. When I asked, relatives explained that it had 10,000 views.

“Today, the video has over 4 million views on TikTok alone, but it is also circulating on Instagram and Twitter. I cannot believe people liked it that much!”
