One day, a senior couple and a junior couple from the same company decided to have a home party together during a long holiday. The senior proposed to the junior that they exchange wives. 'Let me see your wife being embraced by another man...' Watching an important partner being fucked evokes complex emotions, while one also gets excited inserting his erect penis into someone else's wife. She loves it when he ejaculates inside her, so he sprays his semen into the vagina of another man's wife, even going as far as a four-way. The two couples indulge in a four-day affair of being cheated on and cheating.
