This trope applies to couples where both the man and the woman experience enjoyment from the wife having sex with other men. In this trope male partners enjoy seeing their wife being brought to pleasure by other men. There may be cheating roleplay, but these couples are fully secure in their relationship and their love and they both enjoy and get off on the pleasure of the woman. The men want to watch their women get fucked by different dicks and the women want to indulge their male partner's fetish by exploring their own sexually.
