Now both of them have girlfriends, but it seems that their desires only grew stronger, in spite of loving their women. So, what happens when their girlfriends agree to make them indulge in their desires?, and have a relationship only between the limits that desire allows them... This is a bet, to know what is stronger, love or desire? (Source: Queen2408)
