Watch the brutal moment MAFS Australia bride slams sex with groom – and he looks gutted

A MAFS bride slammed sex with her groom in a brutal moment on the show, leaving him to look gutted.

Sierah and Billy’s marriage is beginning to fall apart on the show, and in a shock move the bride appeared to take aim at their sex life on Monday night’s episode.

Discussing her and Billy's night of intimacy, Sierah said: “It felt like a drunken fumble.

“I like Billy but I feel my feelings are fleeting.”

But Billy admitted: “I felt like we were connecting.”;

It was clear for both the viewers and experts to see that Sierah and Billy had different views of how their night of passion had gone.

Meanwhile, in another blow to the relationship, at the end of Thursday night's episode – Sierah and Adrian appeared to be discreetly playing footsie under the table.

While discussing the lack of connection she felt for Billy, Sierah revealed that she ended up confiding in Adrian off screen.

Billy felt betrayed because he had opened up to Sierah with an emotional letter about feeling rejected by his father, while she chose to open up to someone else.

Adrian also confirmed that he opened up to Sierah, leaving his wife totally confused that he would share his past with another bride.

During their chat with the experts, Sierah admitted she wanted more “physical touch”, while Billy wanted an emotional bond.

After finding out that Sierah had confided in Adrian, Billy was left hurt.

Sierah told the experts: “I don't want Billy to think I'm damaged goods,” as she broke down in tears.

On last week's Dinner Party, Sierah, who is married to Billy Belcher, was sat beside Adrian, who is married to Awhina Rutene.

After Adrian and Awhina had a row at the dinner table over how she has a child but feels he is reluctant to accept that she is a mother, Adrian turned his attention to another wife.

Following Adrian and Awhina's quarrel, he could be seen smirking after speaking to Sierah, who had leaned in for a chat.

Sierah then moved her foot towards Adrian's foot, with them playing footsie in a discreet way beneath the table where everyone was eating dinner.

Adrian quickly covered his face with his hand, seemingly rather flustered by their physical exchange.
