‘I want to be more comfortable in my own skin, to live my life to the fullest.’

Standing up against the wall, Danielle says: ‘Just when you’re ready I’ll come to you.’

The voice over says: ‘He arrived as one of the quietest in the group  but now it’s time for Dave to show how far he has come.’

The pair slowly walk towards each other and Dave places his hand on Danielle’s ch3st before pushing her up against the wall.

He pulls her closer and Danielle tells him: ‘Oh yeah!’

She then tells him to put his leg between her legs.

Dave begins kissing Danielle’s neck and as she groans, Emma can’t contain her shock and gasps out loud.

As he stops, Danielle tells him: ‘That’s so good.’

The group cheer for their classmate as he takes his seat.

The voice over says: ‘Some of the others show off their s3xy skills.’

Taylor, Zac and Jason embrace what they are doing, but the voice over adds: ‘But Ben needs a little warming up.’

 As he walks up to Celeste and places his hand on her ch3st, she tells him: ‘Nice and hard.’

He then grabs her waist and she says: ‘Harder.’

Last night saw Zac’s session with Kat come to an abrupt end after making a shock comment on Monday’s episode.

During the penultimate episode of the series, viewers saw virgin Zac say: ‘I want to move forward… I want to touch you and be touched by you.’

However, Kat, the show’s female surrogate partner, was keen to stick to the session’s designated aim, touch, and told him so.

Zac stressed: ‘I came in here confident and excited, and I don’t know if you’re as used to that in this line of work and I don’t know if you find that intimidating.’

After his attempt to take things further, the therapist immediately ended the task and told him to get dressed and leave the session.

As Virgin Island comes to an outrageous end on Tuesday night, it has been revealed that only one of the 12 virgin contestants has lost their virginity.

Accountant Dave was deemed ready by the Virgin Island experts to go all the way on the show, getting it on with his surrogate partner somatic practitioner Kat Slade.
