Fucking her ex in the other room

I suspected my wife for some time now, we would always fight about her ex chatting with her and flirting with her online. She would always deny it but i saw her chats, i saw him sending her photos of his hard cock and his dirty comments, she would reply with the same dirty messages but would always lie to me about it. For some reason even though we would fight about it i would get turned on and jerked off thinking about thier conversation.
I started watching wife porn when she fell asleep and jerk off right next to her, sometimes i know she would be awake and saw what i was watching and doing. 
Some time after she left her phone on the bed, and i think she did it intentionally for me to find it because she wanted me to read her texts. He was telling her ex she would be awake and look at me watching cuckold and cheating wife porn while i jerked off, they would be making fun off me. She made plans with him for him to come over one night to fuck while i was alseep, she said she would give me something to fall asleep for when he got there.
That night she gave me some sleeping pills and told me she had some work to do and dont want to be disturbed, i pretended to take them and went to sleep. I could see her getting dressed in her slutty panties while i pretended to snore as if i were out cold. I could hear a vehicle pulling up in the driveway and her phone ringing, she was talking right there as she was confident i would be sleeping like a rock, she was telling him i was out cold and to just come into the house, she directed him into the bedroom. She came in and when he saw me they started to laugh, he grabbed her by her ass and started kissing 4d too. I wish so much to see it  but i just sat on the bed and started to rub my cock.naval
They went at it for almost an hour, i kept edging myself as i did not want to cum, the sound of her moaning was too good to burst my cum in just a few minutes but when they were done he left and she came to bed. I should have just cum when i had the chance.
I continued to pretend to be asleep but when it was her turn to fall alseep i just had to release all that cum that was built up inside me.
I did not even need porn that night, i just started to masturbate very rough and hard. Ofcourse she was alseep and saw everything and she also knew i was awake during he fuck, i know this because of thier texts the next day.
