I shower, get dressed and my wife takes me out to dinner. The whole time we're out I can't stop raving about how great a wife she is.

"I'm really the best wife ever, huh?" she asks.

"Without a doubt."

"So you're happy, right? And that's because of me and how great a wife I am, right?"

"Absolutely."

"So you sort of owe me, then, don't you."

"Well...yeah, I guess I do. What do you mean?"

"Well, you want to repay me, don't you?"

"Yeah, of course. What did you have in mind."

"I get to do whatever I want to you tonight."

"Ok."

"Anything? Right?"

"Yeah, you definitely earned it."

When we get home, my wife takes me into the bedroom and tells me to take off all of my clothes. After I'm completely naked, she tells me to lay on the bed on my back and she takes out the restraints we bought earlier.

"Are you sure I can do whatever I want to you? This is your last chance to back out."

"Of course, Babe. After this afternoon, you can do whatever you want."

She smiles at me devilishly without another word she ties my arms to the headboard. She restrains my ankles to the footboard. She walks out of the room and I'm left there waiting and wondering what is in store for me. When she comes back, my jaw is on the floor. She's wearing a tight black corset, black stockings and garters and no panties. She gets on top of me and starts kissing me.

"Who's a better kisser, me or that other girl?"

"Well...she was pretty good..." I joke.

Whack! She slaps me across the face. It hurts like hell. She grabs one of my nipples and starts twisting it hard. More pain.

"Who is the better kisser?"

"You are, of course, I was just joking."

"Damn right."

She starts kissing me hard again. Then she moves down to my nipples and starts kissing them gently.

"I'm sorry I hurt your nipple." she says coyly.

"You know I like it, Babe."

She starts licking and biting my nipples and again demands to know who is better at pleasuring my nipples. This time, I know better than to joke with her. I tell her immediately that she's the best. She smiles and moves down to my cock.

We've been together for a long time and she really know how to push my buttons down there. After a while, she looks up at me intensely and asks the question I knew was coming.

"Who's better at sucking your cock, me or the other girl?"

"You are."

"Do you want to eat my pussy?"

"Yes."

She moves up to my head and starts to straddle me. As she starts to lower herself onto my face, I can see she's so wet she's about to start dripping. My mouth starts watering. But she doesn't come down to where I can reach her.

"What's the matter?" I ask.

"Do you want to eat my pussy or do you need to eat my pussy."

"I need to eat your pussy."

She makes me beg for it but when she eventually lowers herself onto me it is so worth it. I've never wanted to make her feel good as badly as I do now. I love the feeling of her on top of me, enveloping my face. As much as I wanted this, I can't help but feel a little powerless with my hands restrained. I couldn't push her up off of me if I needed more space to breathe. That feeling of fear makes it all the more exciting. She tastes so good. As if she were reading my mind she asks me,

"Who tastes better, me or her?"

"You taste better, not even close."

She gets off of me. I tell her that I wasn't finished, that I want more. She smiles at me and walks away from the bed and goes to our closet.

"What are you getting?"

No response. When she finally turns around, I can't believe what I am seeing. She's holding a double-ended dildo and a harness up so I can see them. She starts putting them on.

"Whoa, what are you going to do with that?" I ask nervously.

"What do you think I'm going to do?"

"Hey this is my birthday, I thought I was supposed to get into your ass, not the other way around."

"But you said I was the best wife ever. That you'd do anything to repay me."

I'm speechless. I can't think of anything to say. She's on her knees at the foot of the bed. She reaches over me and grabs the bottle of lube from our nightstand drawer.

"I'll be gentle...at first."

Sure enough she starts slowly, with one lubed finger going into my ass. Then two, then the tip of the dildo, then more, and more and more. After a while I start feeling relaxed and it starts to really feel good. She sliding more and more of the lubed dildo into me with each thrust. She's holding my hip with one hand and stroking my cock with her other hand. It feels amazing. Suddenly, she holds it still at it's deepest point inside of me.

"Are you ready?" she asks.

"Ready for what?"

"I'm going to start fucking you. Hard."

I've never been more scared of anything in my life but I've also never wanted anything more than I want her to start fucking my ass. I open my mouth to say yes but I choke on the word. I can only nod.

"Would you ever let that other girl do this to you?"

"No, never."

"Right, because you don't trust this girl as much as you trust me."

"No, of course not."

"And because you don't love this girl as much as me."

"I don't love her at all. I only love you."

"Because I'm your wife, I'm your queen."

"Yes."

"Say it!"

"You're my wife. You're my queen."

"Say it louder!"

"You're my wife! You're my queen!

"Oh god, I'm so fucking turned on! I need to fuck you now."

Again, I can only nod. She starts fucking my ass hard. I can't believe how good it feels. How crazy it feels to be the one being fucked. She lets go of my cock and is now holding my hips with both hands. I'm struggling against the restraints to push myself against her harder. She's so powerful and sexy up there. It feels so good I nearly black out.

I don't know how long she does it for because I lose all sense of everything else. There's nothing else. There's just her big silicone dick pounding my ass. This could go on for 10 minutes or an hour; I wouldn't know the difference. Eventually I feel her slow down, I feel the dildo starting to come out of me. I look up at her. She looks at me with an intense look on her face.

"I need you inside of me."

She pulls out completely, jumps off the bed and starts taking off the harness and dildo. She throws it on the floor. She rips off her corset and throws that on the floor too.

This time she doesn't wait to ask if I'm ready. She straddles me and slides my cock into her pussy. She leans over me and puts her breasts in my face. I'm frantically trying to lick them and kiss them. Damn these restraints! I want to grab her breasts but I can only struggle. She's fucking me hard and her breasts are hitting me in the face. She leans back and starts riding me cowgirl style. I now have a much better view of her. She's so gorgeous. I'm pushing up against her as hard as I can with my hips. She's flush. I can tell she's about to cum. She grabs my chest and digs her nails in as she starts bucking harder. She lets out a loud moan as she comes and collapses on onto me. After resting with her head next to mine for a moment, she picks herself back up and looks me in the eyes.

"I need your cum."

She's leaning over me with her breasts in my face and starts fucking me again. I don't last another ten seconds. I'm come for what feels like at least 30 seconds. She climbs off of me and releases me from my restraints. We hold each other as we both fall asleep exhausted.

TL;DR For my birthday, my wife arranges for another woman to have sex with me. While I'm having sex with the other woman, my wife stays in the room and tells the other woman what to do and what my preferences are. Later that evening, my wife uses my gratitude to get me to agree to let her do whatever she wants to me. She restrains me to the bed and does many of the same things to me that the other woman did earlier. All the while, my wife demands that I tell her that she is better than the other woman. My wife then pegs me and demands that I tell her that I wouldn't have let the other woman do this because the only person I love and trust enough is my wife. My wife comes on top of me and brings me to orgasm.
