The couple doesn't need to pay the rent if they fuck the landlord

The doorbell is ringing. Someone is at the door. The wife opens the door. That's their landlord. They didn't pay the rent. That's the reason he is here. But the wife is very clever. She tries to seduce him so that they don't need to pay the rent. But the landlord gives her a condition. He said that her husband also has to join them as he is bisexual. The wife goes to her husband and told him about the deal. The husband first refuses but the wife managed to convince her husband. Then they had a bisexual threesome. The wife enjoys that the most.
