Finding out a guy I hated was sleeping with my wife [cheating] [cuckold’s perspective]

There was a guy I couldn't really stand, cocky, arrogant, thought he was better than everyone, typical douche. He was a friend of friends of my wife and I, I didn't really know why they were friends with him but they are. We'd see him at get togethers on the weekend. We'd usually be cordial but it was clear to us we didn't like each other.

It was the asshole guy's best friend's birthday and we had our kids being watched so we could spend a few hours away. It was a large gathering, 20 or so people in a pretty decently big home. Music, food, chatting, and a football game was on. I mingled for a bit but eventually settled down to watch the game. The guy I hated was flirting with my wife, but he flirted with anything with a pulse so it wasn't a surprise. My wife gets flirted with a lot and she didn't seem to handle it differently. I noticed she was on her phone for a bit more one time and I began to wonder, knowing already she had cheated before. She let me know she was going to be leaving for a moment to help a friend that lived nearby but she'll be right back. I let my curiosity get the better of me and I began to look around a bit.

I asked the hosts if I may use the upstairs bathroom with the excuse of the one on the first floor was taken. They were very nice and let me and gave me directions on how to find it. I used this opportunity to snoop around just to see if my wife was there. I was just about to give up when I heard a guy's voice say "oh fuck."

I crept up and put my ear to the door. I could just faintly hear the sound of people whispering in there, not loud enough to make out anything. They were clearly trying to keep quiet but not doing a great job of it. I could faintly pick up what I thought were sounds of making out but over the noise from downstairs it was hard to tell. What I could hear was the metal clinking of a belt being undone and the guy moan, loud enough for me to recognize it as the asshole. I could faintly make out slurping noises as I wondered if it was my wife in there. Those wonders were confirmed when I heard him moan her name. My stomach knotted as I heard that, of all the guys she could have cheated with it's this guy.

After some time of listening to faint sounds of my wife giving this guy head I heard a thud of something falling on the bed. I next heard what sounded like him pulling her panties down. I heard my wife gasp, the bed creak, and stiffled moans next. I could tell they were trying to be quiet but the bed wasn't exactly cooperating. I heard him say "the floor" and them getting off the bed. I only heard the soft sound of their bodies colliding as he humped my wife, along with an occasional muffled moan from her. I was rock hard despite feeling a pit in my stomach. I decided to quietly walk away when it sounded like they were finishing so I wouldn't be caught listening.

She returned back to me like nothing had happened, smiling as usual. As the party wrapped up I shook hands with the guy that just fucked my wife and he had a sly smile that I know knew the reason for. We drove home and she made conversation like usual saying how it was nice, good to see everyone, stuff we still needed to do for the weekend. I just agreed while thinking about what she had done with the guy I can't stand.

When we got home she went immediately to our bedroom and I sat on the couch. After I heard her in the bathroom I decided to go into our room and opened up her hamper in the closet. I dug a bit but eventually found a pair of black panties with cum in them. I examined them and got rock hard. I quickly put them back and she called for me. I went out and she suggested that since the kids aren't back we could have a little fun. I accepted and we started kissing, my mind was focused on what I had overheard earlier. She pulled me on top of her as she fell back on the bed and eventually started pushing my head down. I pushed her skirt up and rubbed her over her panties which were another identical pair. She pushed my head down and I knew what she wanted.

I pulled her panties down and ate her out, knowing the guy I hated had just fucked her and came inside of her. She was very much enjoying it and I decided to tell her that I overheard her. She asked, "what?" And I told her I overheard her at the party. She looked frozen and guilty. I asked if she enjoyed it and she admitted she did. I asked for details and she told me she made out with him, he fingered her, she got on her knees and sucked his cock, he pushed her onto the bed face down, fucked her, and then they finished doing doggy style on the floor. I ate her out the whole time and she admitted he came inside of her. I also found out this had been going on for a while under my nose and they've had sex all around our apartment, our bed, the couch, kitchen, table, shower, everywhere. I made her cum and got her panties with cum in them and she sat me down on our bed, my back resting against the headboard, took my cock out, and climbed over me. She took her panties filled with his cum and moved them close to my face, over my mouth. This was something we have done before that I especially enjoy so it wasn't new. She placed them in my mouth and had me lick some of the cum on them. She wrapped her panties around my stiff cock and pulled it around. She finished me off with her hands with her panties wrapped around my cock as she told me about fooling around with this guy I hated.
