When my ex wife caught and plotted to cuck me

Me and my wife had been married for 8 years when things started to change. One day I was playing golf when I received a work call and they needed info from my work laptop. I called Staci my wife and gave her the password to log in and get me the info. When I arrived home that evening she was a little distant. A week or so went by and we were having sex in missionary and I cummed in her. Normally she would get up and go to the toilet but this time as I rolled over on my back she went to 69 licking my cum covered dick and she put her cum filled pussy on my mouth I tasted my cum as rubbed her pussy on my mouth she stopped sucking me and I could feel her push all of my cum into my mouth. My work laptop is where I watched all of my porn and 2 weeks later I was doing a search and noticed an auto fill for "how to find a bull". I was confused how that got on there so I instantly deleted all searches and history. The next weekend after that Staci said she had made plans for us so don't schedule anything. That next Saturday rolled around and we went to brunch then shopping in the afternoon. Staci had picked up some very nice lingerie and was flirty all day. That evening we arrived back home we had a few drinks and then were kissing when she said let's go to thw bedroom. We went up into the bedroom and was on the bed and she had stripped me down naked she then wanted to tie me up. She used the cuffs for my hands to the headboard and some sex straps for my legs she then licked me and had me rock hard. I then heard something upstairs like someone walking I told it to Staci and she said she would go check. She left the room and I heard her walking above me then I heard more walking and then the bed slamming the wall I yelled to see what was happening then after 10 minutes she walked back into the room covered in sweat. I said what the fuck was that and she walked over and stood over me and pushed cum out of her pussy on my face then bent over to kiss me and mix the cum in my mouth. She then touched my hard cock again and said I knew you would like it. She then told me how she found all my porn and searches on my work laptop and I was going to be a cuck. She then yelled into the other room come on boys. As 2 skinny black guys and 1 young white guy came into the room. The fucked her until she could walk and fed me all the cum out of her.
