Bride-in-law, perverted wife from the countryside x plump, voluptuous wife from the city

"I want to see my wife being embraced by others." We are planning a filming where two wives of different residences and ages who share the same desire, exchange wives and spend the day. Each wife is confused, but the husband agrees to a one-day contract with the man he doesn't know about when he persuades him. The two wives, who joined in the hopes of fulfilling their beloved husband's wishes, reveal their desires by being caressed differently to the man's husband who is dating for the first time.
