"I’m Atom and my beautiful hot wife is Bella Rose. This is our unfinished story.

We are currently both 33, I weigh 175lbs I’m 5’10” with about 6”x5.5” below. She is 5’3” 110 with the softest skin you will ever feel. With soft luscious breasts that just fall into a D.
Both of us come from a extremely conservative christian background. Both being raised to see interracial relationships as a bad thing. Bella at the point of us getting married had disappointing sex with a young man and had a black sex friend that lived 4 hours away that lasted around 3 years. She actually left this guy for me and to have a quote “Christian marriage”. Though I always had a gut feeling that she never got over him.

the first year was great. All the honeymoon glow. But after and for about 8 years our sex life was always once a month or maybe on a holiday or birthday. She never initiated or acted sexually attracted. Deep down I always knew why.

Around year 8 we had stop communicating sexually most of our other aspects were not bad I believe we were and have always been very happy with each other just not sexually.
Both of us had gained weight and really stopped caring about our looks.

around that time I started to see if I could help out sex life. And have believed Bella was strongly sexually attracted to black guys and big dicks. I started down the path of lonely watching interracial porn and loved it. It didn’t take my long to cum every time and sometimes even cumming hands free from just watching. I had found something for me!! (Typically all I’m good for is an energized penis, I can keep it up and going for hours, but not for this, I can barely control myself, well I couldn’t control myself.

it took me a few weeks to work in to Bella my likes. She didn’t understand much at all so it took around 18 months just to grasp my kink (telling you guys, she is innocent and pure). Of course I had mostly convinced her my kink was big dicks not interracial or cuckolding. At this point she begrudgingly let me buy a sleeve for my cock that extended it to 8-9”. She would rarely let me use it. But when she did it was something else. You could just see a fire in her eyes wanting to catch a blaze.
After a few months she would be more willing to use it but still always got very quite and ashamed afterwards.

not long afterwards I talked Bella into a bit of chastity and a small amount of humiliation. Made her very uncomfortable but she could literally just from talking about the stuff work herself up to a orgasm.

I finally worked up the courage to just ask her to ******* with a big dick. She thought about it for a second. While all my previous requests for swinging were sharply negated. Most with responses that she just wasn’t interested in sex.

a few weeks go by and I had talked her into role playing her telling me about taking big dicks. It would get her so horny but would always put her in a bad mood after she came.

we fought often over sex for a while. Bella seemed to want vanilla and I wanted kink.

The changes started when I started to include the fact my desires involved her being with a black man. She started role playing more and actually wanting her toy and others. At the point I’d never seen her cum without me going down on her and her using a vibrator. 10yrs….

but she started having these bucking and hot orgasm like never before just by using a toy and talking about big black dicks. But still she would be upset afterwards.

Again we had gained weight and sorta let ourselves go after having *******. Bella started cooking healthier and walking. Soon she was exercising and loosing weight after 10yrs of saying she was fine getting bigger she started a journey that brought her to the healthy time of her life. Same goes for me. At the time I had no idea the motivation.

typically she would still get angry about me asking her to be with another man. We started watching cuckold type porn together. It opened opportunities to tell her what a cuckold was which she did not like much and said was gross.
But it didn’t change how much she was getting off on role playing these things.

One day during a time nothing sexual was happening I had a conversation with her about how much it would mean to me and how I would appreciate her being open minded about cuckolding me. I told her that it would only make me love her more and I would support her decisions and completely submit to her desires. And that it doesn’t make me feel bad but actually good.

from that point on her after orgasm regrets went away. And our sex life went from once a month to we couldn’t stop. 3-4 up to 6-7 times a day besides her time of the month and this lasted for 3-4 month’s . Then I started begging her to just text with someone. Then the sex slowed down. (She’s innocent and was ashamed of her desires). After a few weeks I had texted someone and had them send her a dick pic.
After that she didn’t want to stop texting and the truth began to come out about her desires. Want to hear the truth’s from her? It a cucks dream."
