So he layed there on our wedding bed, spread eagle, just as so many times before. I really learned to love making him helpless like that, mostly tied to our bed, sometimes chair. In times I really consider buying an Andrew's cross, too. But no basement so it would appear stupid in any part of our house. Gagged with my panties, and horny as hell. Trembling. He knows I'd never hurt him badly, but I do leave marks and bruises with my nails, crop, heels...
He's wearing only his chastity device, silicone birdlocked this time, one out of 7 I have. I have time, he is nervous, excited, in anticipation what's coming next.
Earlier that day, he was a good boy as usual; finished all his chores, gave me two orgasms with his mouth, obeyed everything. Cant remember last time he disobeyed, contradicted or acted in a similar way. He is fully submissive to me, though I remember times he was only kinky. But I dont abuse that power. And it took real effort and training to get to the point at which we are now. He endures and accepts everything, I dont abuse that power. I always was a bit of bizzarre chick, but never sadistic. Now, I love sadism up to certain level, makes me feel powerful and horny too. He loves that I love it, makes him crazy when he sees how horny it makes me. If I beat him, he gets hard. If I kick his balls, he gets hard. If I slap his face more then once, he gets hard. When I spank his ass, he gets hard. And he loves me, adores me, worships me. Totally.
If he licks my feet, he cums providing he is horny enough. If I caress his cock and balls long enough, he cums ruined. If I fuck his ass properly.
So he layed there on our wedding bed, spread eagle, just as so many times before. And I can choose what to do to him. I know he will endure and like, whatever I choose.
I get the key and remove his cock cage. Instantly it went up, hard as rock. His balls swollen, he hasn't cum in days but had to endure lots of teasing. I know that if I let him cum, it will be a geyser or cum. Unless I decide to ruin it.
Slowly, I start to caress his balls and his cock. I need to find proper pace and pressure, as I dont want him to cum too soon. Not before I fuck with his mind enough.
Wanna cum? He nods with his head. I take my panties out of his mouth, he releases a slight sigh. Not yet. I continue my work. He is in a deep subspace, hell he's been in it for months. I know he cant say no.
I think you want to be my cuckold, dont you? Cuckolds eat sperm, you know that don't you? He does not reply since those are not actually questions. Want to see me fuck a big cock of a young stud? Fit stud, six packs and all, right? He is so close so I stop. Cuckolds get only ruined orgasms, you know that? I whisper leaning closer to his head. Yeah you do. And they are chaste all the time as a sign of sacrifice and devotion. He just might cum on his own, without my help if I continue like this. I am gonna get me a boyfriend so I can fuck whenever I want. A steady one. Perhaps I'll cheat on him too, but not with you. Unless pussy-eating is cheating. That is your job. To eat my pussy, my ass, to worship my feet. Yes, that is how it's gonna be. You will be my cuckold. I grab his balls in my left hand, his cock in my right, I squeeze those balls and start jerking him off. I raise my voice ISN'T THAT HOW IS GONNA BE? YOU WANT IT DON'T YOU? SAY IT! 
He cums really hard, his cum covers his bellly, his chest, a little on his face. Yes, he whispers. I feed him a little cum from my fingers, then I wipe him clean with a towel. His cock goes soft, flaccid. I take the chastity cage, on of many, and I lock my property back safely. I untie him, and lay on top of him. We kiss, we hug, we cuddle. I love you. I love you more.

Point being...I was never a slut, never a cheater. Never even thought about it. But, as the time went by, I gave it some thought. Not really to cheating, cuckolding, although it is not really cheating if it is consensual.
But I did accept inequality in our relationship, and pronounced it semi open. Simply because, why say no to opportunity? It does not mean I will ever actually do it, be with another man or woman. It just means I can and he cannot. And it is a turn on, a real intense one. Knowing I can anytime I want, and he cannot. Nothing wrong with being turned on, right?
