cheating! He sends his wife home and fucks me!

I had a party at my house last night and a couple I know stayed the night. In the morning his wife was still asleep, he flirted around with me and said cheekily to me that he could send his wife home and fuck me. I thought crass, but wasn't averse and told him then he should do it, I'll wait in the bedroom. I thought he wasn't coming anymore and the door opened blatantly. I don't know what he told his wife but she was gone and he fucked me.
