Open House: Maddy watches Nathan kiss Precious

A couple who participated in the Great Sex Experiment almost broke up after trying out threesome for the first time for the hot new show.

Nathan and Mady’s time at Open House almost had a heartbreaking aftermath.

The Channel 4 show gives loving couples the chance to open up their relationship with new sexual experiences and see if relationships can survive having sex with someone else.

Committed couples head to a luxury getaway to discover whether being open and having sex with others can strengthen their relationship.

But Nathan has revealed he can’t handle the idea of ​​a steamy three-way street – and it almost pulls them apart.

But things have changed and since the show ended.

The couple joined an online dating app looking for a third person and said they were “stronger than ever”.

After meeting Precious at a social gathering on the go where the experiment was taking place, they invited her to stay the night in their bedroom.

Nathan is very hopeful, saying: “It will be very good, more women, more pleasure.”

But he doesn’t like the experience.

He felt left out and like a “spare” and when Nathan didn’t want to be involved, Mady told Precious: “It’s a pity we couldn’t go out and let him sleep.”

Nathan told Mady: “You made my first experience so bad. You made me feel like a spare on purpose. You made Mady leave the bedroom crying.

The next morning, things were still so tense between the couple that Mady was in tears again when Nathan told her he didn’t know if the relationship was right for him.

After speaking with Dr. Lori, the relationship expert in the trial, the two agreed to talk more openly about their feelings and make sure everyone felt included.

Mady said: “I felt so bad, we were so focused on my jealousy, how would I think, we didn’t really take the time to think about how you would feel.”

They decide to try out three other people and invite another girl, Grace, to join them for the night.

“This time with more communication, the trio succeeded and Nathan and Mady left the resort feeling ready to go public with their relationship.”

Open House: Great Sex Test airs at 8pm every Friday on channel 4
