As the two of them start to get more and more intimate, the husband can't help but feel a mix of anger and arousal. The other man has a massive cock, and the wife is clearly loving it. The husband finds himself getting more and more turned on by the sight, and before he knows it, he's joining in too. The wife is getting off on both men at the same time, moaning and writhing as they fuck her from both ends. The husband can't believe how much he's enjoying this, even though he knows it's wrong. The scene ends with the wife getting covered in cum from both men, leaving her dripping and satisfied.
