Wife used by businessman.

My wife was told to make sure this guy had a nice evening out, when he dropped her off he came in and told me he was going to use her as he liked, he for*ed himself on her holding her head while he pumped into her mouth. Then he held her arms down spreading her legs and pounded her Pussey telling me all the time how tight she was and how he was going to fill her up with his cum. He insisted I watched closely as he kept prodding her, he said after he certainly got his money's worth ???
And intends to bring a friend next time to spit toast her.
Do I let him ?
Will my wife allow it ? She has not objected to anything as yet ?
She seemed to like being a submissive to his dominant nature and did everything he told her to.
Do I agree ,.. y/n ??
