My dirty little ex

I worked at a factory where I met my girlfriend. She was hot and sexy and petite. We got together and ended up in a relationship ,we fucked at worked at lunchtime when the bosses had gone out and she regularly sucked on my cock and swallowed my spunk. We had been dating about 2 years when this new bloke started at our place. He instantly started to chat my girlfriend up which he knew. She would tell me on a night that he would try and get her in the corridor and press up against her with his big dick. I was jealous of him and hated him. So cocky and full of himself. I love my girlfriend and one day we had an argument over nothing but it was so heated that we exchanged words we didnt really mean. She told me to get out and go live with my parents for a few days while we sorted things out. This was on the wednesday. On Friday I rang her and said I was sorry and can we get back,she said "look,not tonight im out with a few friends can we talk tomorrow?" I said "ok,i'll ring after dinner ok" and with that I hung up. I kept thinking about my girlfriend and i knew she had been with guys when she had split up with other ex's for a few days ,and this got to me. My mind was wondering..I was pacing and I couldn't eat. I got my coat and drove around town to see her...I couldnt find her at all, I drove to her house but no lights was on. I texted her while waiting across the road from hers and I got nothing in reply.I waited for about 30 minutes as she didn't stay out long anyway and I knew she would be back home anytime now. Then I saw a couple walking up the road but all I could see was shapes. It was dark but it looked like my girlfriend. She is petite and she was the size really,Im thinking "no,It cant be. She is with another man" Then as she walked underneath the street light I could see it was her and she was with this guy from work,my heart started racing and my anger was now building up..They stopped outside her gate and chatted for about 5 minutes and then her kissed her but she didnt pull away,oh no ,she got right into it and was kissing him so hard..Then just as I got out of the car she grabbed his hand and took him into her house. I ran across the road and as i was walking down the path I noticed the kitchen light come on at the side,so i walked slowly and quietly down the path to this window and see what was going on. As i approached the window I saw her face first and noticed she had her eyes closed and her hair was moving back and forth then as i got closer this guy had her bent over the kitchen table fucking her hard,I was very angry and wanted to smash the window but I got really horny and my cock grew hard..I was feeling my cock through my jeans he grabbed her and turned her around and sat her on the table,his cock was bigger than mind ,I was so jealous..i undid my jeans and got my cock out and started to wank really hard to my slut girlfriend enjoying this man I hated and she knew I hated him...I shot my load all over the wall. My emotions were changing all the time from pleasure to agony and pain..jealousy and hatred. I soon got back in my car with my heart broken and went home to sob over this dirty little slut of mine but I couldnt help feeling horny and again i ended up wanking. The next day she rang to say sorry but it was over,I tried everything to get back with her but i knew it was over. we all ended up getting laid off over the next few weeks so I text her to find out what was happening. She told me everything that night they met for dinner and had sex at her house. I was gutted and she didnt know i watched them. We met up in my car and chatted and ended up fucking but we it was just friends and now she is seeing another guy.gutted.
