Our Good Girls and their Guys get kinky with food and foreplay, find their inner exhibitionist with a private striptease, and explore pain and pleasure with nipple play.

The bedroom experiment continues as three self-confessed good girls and their guys look for creative ways to improve their sex lives. It seems nothing is out of bounds as the couples try various kinky challenges, involving sex toys, role play, blindfolds, bondage and even a full-sized sex swing.

The couples continue to try new things in the bedroom - or rather not, as this week they are challenged to be more creative in their choice of love-making locations. They also use a spinning wheel game to discover new erogenous zones, getting to know each other's bodies in ways they have never done before.

Our good girls and their guys open three kinky boxes containing a remote controlled vibrator, a kinky cleaning kit and everything you need to know about bondage.

The couples attempt to drive each other wild by sharing their most intimate moments with each other. They also use a box full of sex toys to try solo and mutual masturbationand indulge in one of the UK's most popular fetishes - dressing in latex and leather.

The good girls and their guys explore the ins and outs of oral sex, try their hand at making a sex tape and strap in for a little bit of strap on action.
