Recently my wife found out about a relationship I had just out of college with a girl I had been dating for a couple of years. We moved in together and lived in an apartment when a young black man moved in a couple of doors down. He and I began hanging out playing ball, having drinks and watching some of his videos. It led to him showing me interracial videos he had taken of himself with other white girls, girlfriends and husbands while they watched. I was blown away. After a few weeks, he suggested that perhaps I would like to have him seduce my girl. I told him she'd never go for that and truly believed it. He had me take home some IR videos that I "accidently" left in the player. It had videos of black men with a young blonde that looked like her. At first she seemed surprised I would watch something like that and a little disinterested but after a while of me bringing them home, I found she had been watching them (they sometimes were not rewound). After a few weeks of watching the videos, Marc (my neighbor) had me bring Lynn down for drinks and then after several rounds say I was going out for more mixer. Instead, I watched by the window outside as Marc seduced my girlfriend. It started with him showing some of the videos of him and another blonde and then he began to kiss her. She at first seemed like she was going to resist but when he placed her hand on his crotch, and she felt his package, she just surrendered. In minutes she was on her knees sucking his cock. That night she came home with a pussy load of cum. That was just the start as little by little she had sex with Marc almost daily. Rarely was she in our apartment when I came home and when I went to his place, she was always either naked or wearing just a shirt with no bottom. He had told her how I had allowed him to fuck her and asked her what kind of man would give his woman away. Over the course of weeks, while she still slept with me, kissed me, and even cuddled with me in bed, she stopped having intercourse or oral sex with me. She still had me go down on her, particularly after a session with Marc. While I didn't want to, it seemed the only way to still have sex with her. It was just a few months after this that Marc began having other buddies over and she was fucked by several black guys. Often with Marc requiring me to video it. The guys taunted me, which was humiliating, particularly when Lynn herself joined in. But I found myself getting so turned on by the sessions as I jacked off watching these black guys fucking my GF. Often the guys would have her look me in the face and tell me she was a Black Cock Slut and a Whore for Black Cock. While Lynn shaved her pussy, I was shocked one night when she came out of the shower sporting a black tattoo in big bold letters that said MARC just over her cunt lips. It should not have surprised me but one night in bed she told me we had grown apart and that she was moving in with Marc. She loved me but she loved him in a different way and that I would always have a place in her heart. It had never occurred to me when it all started it would end with me losing my GF. It was then that Lynn told me after that first night Marc and she were together he would not allow her to fuck me any more. I was not to have my white dick in her pussy nor was she to go down on me or even give me a hand job. Basically it was my dick or his cock and she made that choice after that first time with him. The night she broke the news to me, she said it had been almost five months since we had sex anyway. The real dagger was when she told me she was carrying Marc's baby. That was all about 25 years ago. Since then I married and divorced and recently remarried. The problem is my new wife Tracey recently ran into a girl who knew Lynn and I in college and told her most of what had transpired back then. Up until a few weeks ago, that chapter of my life was a secret and buried deep in my past. Tracey has confronted me and keeps wanting to know more and more. In bed the other night she was asking how I felt watching those black cocks in my girlfriend. I know Tracey has never had interracial sex but I also know she was fairly experienced in sex before we met. I can tell Tracey wants to explore IR sex but I am really scared I might lose her like I lost Lynn. I have to admit I was turned on watching Marc and his friends fucking my girlfriend and I have jacked off hundreds of times thinking about it. The other day I opened the computer browser only to find Tracey had been visiting free IR websites. One she had been visiting linked to this one so I thought I would check it out. There's a part of me that regrets Tracey bumped into my college friend but then again, I have been excited ever since. Hopefully reading some of the stories of other men may help me make up my mind. That is - if Tracey doesn't act on her own.
