This is a long one so buckle up. Everything in this is absolutely true, and an accurate retelling of what I experienced two nights ago from writing this story.

So my fiancé (31) and I (26) have been discussing a cuckold lifestyle for some time now. I've known I've had this kink for a few years and I've always fantasized trying it for real rather than just role-playing it or watching porn of it. We had experimented here and there with other people, but the problem was just that I was too good. Everyone we found was lacking in either size, looks, stamina, or any number of the former. I satisfied her too well and no one we found could compare. She cums on my cock almost every time we have sex, and even if she doesn't, she's close enough to finish with a toy within just a few minutes. Now that's not to say I'm amazing or anything. I think I'm above average, but I'm by no means in the top 1% or anything; or even the top 10%.

Eventually, we decide we want to take the next step and find someone a little more permanent. Part of the problem too was that she genuinely just loves me too much to find other men attractive. Sex for her is very intimate, so finding a suitor capable of satisfying her would never be possible through one night stands. To solve this we put out some ads on reddit in our local r4r subreddits looking for someone to be our bull long term, who'd also be our friend; come hang out, play board games, share some drinks, etc. That way she has a chance to actually build a connection with him (of course with considerable ground rules to prevent anything getting too far).

Well we found the perfect guy... he's well over 6' tall, while I'm just under. He's freaken blessed with a huge package. Well over 8 inches and fat too, while I'm just 6. He's handsome, fit, and charismatic.

He comes over to our place and settles down on the couch on the other side of my fiancé while we have a show playing in the background. We start off talking and getting to know each other. However, not even 10 minutes into us talking, he's already feeling her up. I immediately got hard inside my chastity cage watching him take charge like that. She gasped when she felt his cock under his jeans. I could immediately see how turned on and shocked she was. She pulled his cock out and her eyes went wide, taking no time to throw her mouth around it. He grabbed her hair and let her work her magic on him. She grabbed his cock with one hand and tried to deep throat him. Normally she can deepthroat me without issue, and she can only fit a few fingers around my shaft while sucking. With him, however, it was her whole hand and she still couldn't get the rest all the way in. It was insane how big he was. I genuinely didn't think it was possible to be that big. I felt so small compared to him like I'd never felt before.

Before long, she stopped and turned around to look at me. The lust in her eyes was a look I'd never seen before from her. She asked me in almost shameful whisper, "can we move to the bed?" I nodded in approval, knowing no matter what I said, this would be happening anyway. I knew that what would happen next would be irreversible. She'd never be able to see me as good or dominant, or satisfying again in the way she likes. I'd always be compared to him from now on; but I secretly wanted that.

They both moved to the bed and pretty much immediately got to it. He tossed her around onto her stomach, which happened to be her favorite position, and one I'd experienced as not being able to fully hit her good spots in quite the right way, so I'd eventually gave up. Turns out, as I'd soon find out, all it took was a bigger dick. He pushed into her with one slow motion. She was moaning louder than she'd ever moaned with me. Her hands gripped the pillow that her face was buried in. Her ass pushed up against him hungrily. Her body shook as she struggled to take his massive size. As he began to thrust, her toes curled and she lifted her head up to breath through inconsistent and shallow breaths. Occasionally, through whimpering moans, she managed to eke out a squeal of, "he's so much bigger than you. God he's so much fucking bigger. He's so much better. Holy shit he's hitting all the right spots that you don't".

Every word carved into me deep, and painful. But with every cut of her words, my dick throbbed more inside the cage. My heart raced. I was so jealous of him. Not that he was fucking her, because I could fuck her whenever I want, really. I was jealous because I knew I'd never be able to satisfy her like that. I'd never be able to measure up.

Finally, he couldn't hold back. He gave a few more powerful thrusts, and with a loud grunt, he came inside my fiancé. I watched his cock throb and pulsate, imagining that each one shot another stream of his seed inside her. There was no protection since she was on the pill and we told him he could. So with his seed now inside her, her pussy was now his. It'd never be mine again.

Yesterday, she confessed to me that she'd been fantasizing about him all day. She told me she wants to fuck him all the time now and that she'd essentially only want him from now on. I honestly couldn't be a happier cuck, and I'm so ashamed of that. I may be going pussy free a lot more often moving forward and I don't know if I should be excited or afraid. Regardless, I'm nervous, but I got what I wished for so who am I to complain?
