This Is A True Story And I Don't Know What To Do

My wife and I have been married for 10 years now she's hot as hell cute face small tits thick thighs beautiful calves and a sexy round ass you could eat food from lol. While growing up I thought she was outta my league with a hot body like hers! But here's where things get spicy. My cousin schooled with us as well and let me explain the experience we had together. One day we both felt like we didn't wanna go to school so we stayed at home while alone in the house I went out to smoke some good weed got back and my cousin askes me if I've got any porn? I get out some movies I had hidden from everyone else at home and put it on! While watching the movie he asked me if I would like to wank and he would do the same! Just like every young kid out there am young dum and full of come lmao so I waped out my quit boldly as I believed I had a big cock. 7.5" to be exact but I was a thin guy so my cock was not so thick,where as now its a big 9"after banging my wife for 10 years his gotten some muscles. Back the the story While being hard and so horny I look over to my cousin and there, the most thickest straight(my cock is uncircumcised and a little bent to the left) circumcised cock I've seen boy was it thick his head was so much bigger then mine. We both start beating our meat watching that women get banged in the porno I start to feel my cock build up steam and boom I expoded, shotly after he did too. I got up went to smoke again got back to find the place all cleaned up! He cleaned up my used sperm filled cloth and from then we wanked a few times after. The reason for explaining that is while my wife and I were banging we have dirty talks to build up our sex lust I brought that topic up and what I did with my cousin while we were younger and this blew her top off she got so horny and excited she was coming for no more I started to explain to her how much bigger his cock his that his circumcised and how much bigger his head is and this was making her come super hard. I started to give her details about his big thick cock his not as long as me maybe 6" but the thickness and head size would definitely stretch her well fucked hole! Even to date it will get stretched. I still believe his thicker then me. So I was so horny that we ended up talking more and more every time we had sex and I would fish her out as to why she's getting so horny and she confessed that while we all were in school he flirted with her big time and wanted to get into her pants from the time I was busy wanking and watching porn. He was throwing his bones, she said she didn't know we had big cocks in our pants and she had to move to another town she said while she stayed there she had sex with the boys there and they WERE nothing like mine or what I've explained to her about my cousin cock! She said if she only knew she would have had a gang bang with us along time ago! My heart and feelings are all over the place what did she mean by that statement "if she only knew what we had in our pants she would have fucked us, if we ever asked her she would have skipped school and banged the both of us along time ago) omg what does this mean has anyone been thru something like that I don't know what to do and how to take it from here.
