What an interesting night!!!

Well it was a pretty interesting night I (38)got home my wife (39) was in the kitchen washing dishes so I walked up and hugged her from the back making sure my dick slid right between her ass then kissed her cheek and asked her how her day was she said good we talked for a bit while I just sat there rubbing her ass while moving her back and forth I slowly got down and just shoved my face in her ass right about then my oldest(19m) comes around the corner. She kind of pushed her butt back telling me to get up so I kissed it and got back up when I did I asked him how his day was. Now I should say this is not the first or even 10th time he has seen this so it was pretty normal. While im talking to him I have my dick pushed against her ass and my hands caressing her pushing up her pajama shorts so he can see her ass and panties. I got so hard my wife could feel me getting bigger and harder. After we talked he walked out and I moved since I had to wait for him to leave since I was rock hard but before I did I told her how much I couldn't wait to have fun tonight. Not much happened after that until we got ready for bed my wife asked if I still wanted to have some fun and she said ok well get up and close the door I said what if we leave it open she was very against it but after a couple min she compromised and we left it cracked about 6 inches. Which is all I really wanted that way if he wanted to look he could see . So she laid on her stomach and asked me to scratch her back first so I did then started to.kissing her back before I made my way down started kissing her ass and shoving my face in it. It was perfect cause when she got on all fours to ride my face she was positioned right at the door. I sat down there and ate her out from.the back for a while before she rode my face and came all over it. She usually makes me stay and lick it all up until she wants me to get up so I stayed down for about another 5 min just cleaning and smelling her then she finally let me get up I asked her if she still want me to tuck her and she said yes but hurry up and I said ok got up and slid in while she was still on all fours I started slow at first but she told me to go faster and harder so I did after about 30 seconds im fucking her as hard as I can she is moaning very loud at this point I hear something in the hallway I dont think she heard cause she didn't react at all but I knew what it was and instantly came. After a few more pumps I pulled out she laid down and spread her legs and told me to clean up my mess so I licked her clean then went and cleaned myself up. Now idk how much was seen or heard but I can only imagine im hoping he will bring it up next time we are alone but who knows. I will keep yall updated if anything else happens but im pretty sure we are making progress!!!
