He was smaller than me [cucks perspective]

My wife hooked up with a new guy this past weekend. He's a super cool dude, and she was really into him when we met to get to know each other. He got to our house, and she met him at the door. They kissed a little and headed to the sofa, he and I shook hands, and they sat down as my wife started to give him a blowjob. I was sitting in the chair across the room, locked in my chastity cage, getting excited fast like usual. The more I focused on his cock it didn't look much bigger than mine, if at all. As they started fucking, my wife was making him feel like he was a pornstar; keep saying how big he was and making her pussy feel so good. It was definitely entertaining and a great act. They finished up he had a massive cum load in her, and she asked him if it was ok for me to clean them up, he agreed, and I cleaned up my wife first, and when I started on his cock I knew instantly he was much thinner and felt a little smaller than me. I'm just under 4 and a half inches so I'm small, but he had to be less than 4, maybe even close to 3 to 3.5. it felt like I was sucking on one of my fingers or something. We all kind of relaxed for a few minutes, and he cleaned up and left for the evening. When the door shut, my wife looked at me and asked if I had enjoyed the show. I said yeah, but how did I enjoy it? She said she could barely feel him, but she actually picked him for that reason. She wanted to show me that my caged dick was still no good to her. It was super hot and turned me right back on as I started to get hard in my cage again. She told me to go to our room and get ready for some strap-on action, and I'd be wearing the big dildo so she could actually cum. When she got to the room, she was on FaceTime with him and he was thanking her for a good time and said I hope you and your husband enjoyed it. I'm not sure if he or I got the humiliation more.
