***************FORREST************

My wife, Amber, enjoys being fucked where I can watch. I think our beginning started differently than most. I didn’t tell her I wanted to watch, and Amber didn’t either.

It happened on our fifth anniversary when we were dancing and drinking at Good Times when a guy named Owen came by and was talking to me while she was in the restroom.

He was telling me that the enjoyment you get from your wife increases dramatically when you see her enjoy dancing with someone else. The someone else being him, Owen.

When Amber came back, I introduced him as a guy I knew. He got her to dance with him, and together, they were spectacular. She loved it, and she showed it, too. Eventually, they were too clingy, and I cut in and danced with her for a while. 

When we were home, I undressed her in the living room, where I made love to her on the sofa. Owen’s prediction was true; the tension between us was epic. I kept thinking about what I’d seen between them on the dance floor. When I came in her, we both erupted. 

When we eventually went to the bedroom, and I was holding her, I said, “That was special, wasn’t it? Um, you sure enjoyed dancing with Owen. Didn't you?”

All I got from Amber was a murmured, “I did, yes.”

We ran into Owen often when we were dancing, and they always got a few dances in. In fact, it was almost like they were fucking on the dance floor. 

She was so different with him. I was getting jealous.

Finally, I commented on it to Amber, “It almost looks like you're fucking out there. I think…” 

Amber interrupted me. “Forrest, there’s a reason for that. It’s because we are. We are fucking. It started, maybe the second time we danced? I’m not sure. I’ve wanted to tell you, but couldn’t.”

I was speechless for a while until Owen walked over and greeted me. “Hi Forrest, how’s it going?” He said with a smile.

Amber interjected, “Owen, I told Forrest about us. Um, I just told him.”

He took Amber’s hand. “Do you want me to stay, Ams? Or what?”

He had a nickname for her, Ams. God Ams? A pet name.

************AMBER************

It just came out; I’d wanted to come clean for weeks, and the opportunity just appeared. Now what? A huge fight, divorce, what? 

How I allow myself to be treated is another thing. Will that make it worse? It’s how I need to be treated, I think.

“Forrest, um, let me think. God, I didn’t…I don’t know; I didn’t think about…”

“He knows now so…” His voice trailed off.

“You know what I told you? I’ve wanted Forrest to know from the beginning.”

He looked at Forrest with a smirk and said, “I got her to meet me after the first time we danced. She said she had a meeting, but she was at my house,” he laughed. “I think you need to see her with me; what do you think, Amber?”

No, Owen, don’t do that, please.

I knew Owen wouldn’t relent; he loved controlling people. He adored humiliating me, especially. I knew I had to say yes.

“Yes, Owen, I know that's what you wanted from the beginning.” I looked at the floor as I said it. 

“Let’s dance one more time, then Forrest can meet us at my place. What do you think?”

Owen gave me his hand to stand, gave me a lover's kiss in front of Forrest, and led me to the floor. He was holding me while we danced, practically fucking me in front of everyone.

Leaving, he was holding me like he owned me, and my husband trailed behind like a whipped puppy that doesn’t know what happened.

***************FORREST***************

I was shocked by what Owen and Amber had said. He started fucking her right after we met him. How did he do that?

I trailed after them, mainly looking at the floor. He’d handed me a card with his address and told me to meet him there. 

They were in the driveway when I drove up. When I got out and approached them, he was opening the door for Amber like a polite boyfriend.

When Amber got out, she was completely naked except for her shoes. He had his arm around her naked shoulder and was holding her tit.

They walked to the front door, and before he opened it, he turned and kissed her while fondling her tits. Even more, she was accepting it, enjoying it. I heard her moaning his name in between, saying, “Yes. Harder Owen.”

When he had the door open, he gestured for me to go first, and I saw her lift her head to kiss him. She walked in and then kneeled in front of him, and I saw her glance at me before saying, “Owen, uh, what…are...”

“You know what’s next; we’re here so you can show him what you’re really like when I fuck you.”

He looked at me and then commanded her, “Tell your husband what you are when you’re here. You can look at him while you’re telling him.” He glanced at me with a satisfied smile and finished saying, “Then get your collar.”

She looked at me, and I saw she was trembling. “F-Forrest, I’m his C-CUM SLUT. God, Forrest, I’m his cum slut. He can do…hell, he can do anything. I’ll do whatever he says.”

What the hell? I’ve been so careful, afraid to push her. That's not a problem for him. Or her, I guess. A cum slut? I’ve never…

She started to cry as she finished, “Forrest, I need him using me. Owen, he’s trained me to need him. Please understand. Please.”

What's happening to us? She’s so different now; I can’t believe it. I don’t know what’s going on with either Amber or me.

Amber looked at Owen and said, “You want me in my slave collar?” When he nodded, she crawled over to a cabinet, opened a door, and pulled out a black collar with large shiny letters on it that said Cum Slut.

She was holding it in her hands when Owen said, “Amber, ask Forrest to put it on you.” He grinned and added, “I want to watch your husband putting your cum slut collar on.”

She wanted to resist, I could tell, but she ended up holding it to me, saying, “Put my collar on me, Forrest. Now, I’m not hiding it from you. I am Owen’s cum slut. His slave. He’s already made me do things… terrible things I wouldn't believe I could do.”

She looked at me with tears and continued, “I hate it, but I have to do it. I want to do it for him, while I hate it. When you find out, I’m afraid you’ll hate me."

I took the collar from her.

Putting that collar on her makes it real. Why is my cock reacting this way? What has he made her do or done to her? 

Cum slut? I can picture what that means. He makes her beg for his cum. 

“What has he made you do, Amber? God, Amber.”

She was crying, “He’s trained me to ask for him to; Forrest, I have to beg him to come on me. He comes on my, um, tits, and on, I have to call it my cunt. He fucks me, even my ass, like a common slut. He loves treating me like his slut.

“Wait, those times you had to finish projects, that girls’ night out, you came home in the morning—you were with Owen?”

He smirked as he said, "She loves it when I treat her like a slut. That's what you are, aren't you, just another slut to be fucked any way I want."

That’s it. Owen is doing it to Amber. He doesn't respect what she’s doing for him; if she wants to be a slut, she’s my slut. I’ve been so careful to not shock her; hell, that ends here. I’ve never used the words cum, cunt, or even tit.

“Owen, Amber is going home with me—NOW. We’re leaving and going home.” I took her hand, and we left. We left the same way she came in, naked except for her shoes. Well, and her collar. She was trying to protest, saying, “My clothes,” but I ignored her.

I got her in the car and drove off. We got a few blocks, and I pulled over and looked at her. 

“Amber, you’re not to talk to him, see him, or be around him. Do you understand? From now on, you’re going to be MY slut. Mine!”

She was still trying to protest, but I overrode her. “I’ve been too timid with you. You’ve been doing things for that bastard Owen that you should have been doing for me. You think you’re a slut because you do things with him. You're going to do what I tell you to now.”

When we got home, I parked in the drive and, emulating Owen, made her walk to the door naked. Again, except for her collar and shoes. 

She was trembling as we entered, and inside I made her kneel in front of me.

“You’ve been a slut for him; well, now you can be a slut for me, Amber.” I removed my trousers and boxers, standing in front of her. “Now, stroke my cock and make me cum on you.”

She hesitated, reached for my cock, and started stroking it. She was looking up at me while she stroked it. 

I kept picturing her naked, begging for his cum, and I could feel my balls tightening; the picture was so erotic, so arousing. She felt my cock getting ready, and she pulled back, so I had to grasp it and finish with a couple more strokes. When I started to cum, I aimed it at her face and tits.

I heard her gasp, “Forrest, god,” before she ended it with just inarticulate noises.

Now she’s my slut. My slut. I wish I could make her clean my cock. Maybe later.

***************AMBER***************

I leaned forward and put his cock in my mouth and sucked it clean before I used my fingers to collect his cum.

This is so much better, tasting Forrest's cum, not Owen's.

When I licked my fingers, I searched his face, looking for his reaction.

“Are we going to be alright? Forrest?"
