After hearing an adult man sucking milk from his partner’s breasts, viewers of Breastfeeding My Boyfriend were left “grimacing”.

Last night’s Channel 4 documentary featured Tip, a Korean-born man, and Button, his partner, who now live in the US. They explained how they don’t see adult breastfeeding as a fetish. 

The couple then went on to explain how they sell videos online that show them breastfeeding. 

The horror of Tip’s actions was captured on Button’s sofa. He was ‘latching on’ to Button’s back, while the camera zoomed into and captured every sound he made. 

‘The sucking, squelching sounds are just too much. It’s an actual turn off instead of turn on for me,’ wrote one, while a second penned: ‘I’m grimacing when that s*** starts.’

A third was added: “Oh god.” The noise! The noise !!!’ while a further penned: ‘The sound of a grown man latching on a t** is going to haunt my dreams tonight.’

Another person simply stated that he felt sick !!!’.

The couple shared their video, which they shared on an Internet porn site, to explain how they first discovered that there was an adult breastfeeding community.

The clip has been viewed more than 300,000 times since then. Tip explained that he hoped people would have a wrong impression of it but that people understood what we were trying convey.

Button described the online reaction to their message and said, “People just came out the woodwork.” They were asking for more. It’s not available anywhere.

She continued: “It was really exciting to discover that we weren’t the only ones in this type of relationship.

‘We decided to share our adult nursing relationship because it’s such a big part of our lives… People think it’s a sex life thing, but it’s part of our lives, it’s part of our relationship.’

“The only way to share this with anyone is through a porn website, because it’s not possible to just share it on Facebook.”

Tip explained he was abandoned in a Korean orphanage and wasn't breastfed as a baby, and suggested that may be why he's 'drawn to it so much as an adult now.' Pictured, with Button

Describing how the process makes her feel, Button added: ‘We will always make the time because it is important emotionally and physically to us.’

“It’s like being in a warm bath with a feeling of contentment. I feel closer to him than any other time.

“This is extremely intimate. I feel very protective of him, and he is my most precious possession.  

They were also filmed for their fans and held a question-and-answer session. 

In response to one person who was intrigued about the taste of the milk, Tip explained it’s like ‘cold cereal milk… milk with a little bit of sugar in it.’

He said that he sometimes can taste alcohol after drinking.

Tip continued to explain how he was left in a Korean orphanage. He said that he wasn’t breastfed as an infant, which is probably why he’s so drawn to it as an adult. 

The couple were seen heading home after working a night shift elsewhere.

Walking down the street, Button moaned that her breasts were hurting and told Tip: ‘Baby, I desperately need you to nurse. I’m suffering. Is it true that you don’t want the car to do it?

Tip replied that she would prefer to ‘nurse’ at her home, where he can relax and enjoy the company of his family.
