The seat belt warning chimed as we pulled away from Mia and Chris's house. My wife Alexa always waited until we were out on the road to buckle up, which always bugged me, and she knew it. I felt her intentionally letting it beep, with extra hostility in the air between us.

She fully admits that she was a huge nerd in high school and most of college, she spent most her time with her face buried in books and never had a boyfriend. And, looking back at her old pictures she wasn't doing herself any favors. And, no she wasn't one of those cute nerdy girls, she was like the red headed version of the "Ermahgerd" meme girl.

Alexa had only had sex with me and I had only been with my prom date and one girl in college, neither relationship lasted very long. The funny thing is, they were both virgins when we hooked up, so I didn't have any experience with someone who had other partners. It was while dating Alexa I realized how fake porn was and became convinced most women only have clitoral orgasms.

We'd been together almost five years and married for four, and while most of those were good, it seemed like we had hit a rut. About nine months ago, in a moment of vulnerability, she shared that she wished she had experimented more before we married. It wasn't that she didn't love me or still wanted to be married; she just felt like she missed out on being young and single.

We tried to spice things up a bit by watching some spicy videos together, and she even bought a dildo to add to the small bullet vibe she had purchased a couple of years ago. Honestly, it always made me feel uneasy using the dildo on her, it seemed like a glaring reminder I came too soon.

None of that seemed enough to keep the excitement going, and for the past couple of months, we rarely had sex. More times than not Alexa would say she was too tired, or just say she was fine and didn't need anything then give me a handjob. As soon as I came she'd ask me to use the dildo on her, saying she changed her mind. Even then she needed both the dildo and vibe on her clit to make her cum. I loved her and found her lustfully hot and wanted to make things right, I just didn't know how.

At 5'6", she's a perfectly average height, and her long red hair is striking against her cotton-white skin. Her cheekbones, long neck, feminine frame, and tight tummy were the result of intense discipline at the gym and great sacrifice in the kitchen. She'd lost nearly 30 pounds in the past year, and while she's always been cute, now she was gorgeous with a strong jawline, firm legs, and perfectly perky B-cup breasts.

I had always been the more fit one between us, and it didn't bother me that she was a little heavy. I am 5'7 and weigh about 170 pounds, with broad shoulders, a 34-inch waist, a beard, and thick dark hair I keep trimmed with a fade.

After backing out of the driveway she put the car in drive and made it halfway down the street before she finally buckled her seat belt, and with a clear firm voice, she let me have it. "I can't believe you just did that!" She gritted through her teeth, "You didn't even ask me." She fumed.

I was completely caught off guard, "Jesus," I sniffed, "I thought that's what you wanted." I pleaded.

"Well, that's not the point... what I wanted was for us to talk about it, and you never did, and then you just made the decision for both of us." She fumed, her body was tense and her voice was stern.

I sat there wondering what I could do to make it right, thinking about what she was saying. "Look, I'll text Chris and tell'em we changed our mind. I am sure he'll understand," I pulled my phone out of my pocket.

"God no!" She grabbed my phone. "I think I'd literally die from embarrassment. You made the choice, now we have to live with it." Her voice quivered as she confronted me, scolding me like a child.

Last week Mia and Chris had been over to our house, like they had dozens of times before. We've been friends for over three years now. Alexa and Mia teach at the same school, and Chris and I have a lot in common, though they live farther out we still get together often.

The girls had spent some time together in the kitchen while Chris and I watched the game. After they left Alexa filled me in on something they had talked about. Mia and Chris were interested in taking our relationship further and invited us to spend a night with them swapping partners. They had told us months ago they were swingers and just knowing that about them set a fire inside my wife that couldn't be ignored.

The way Alexa brought it up, and knowing how she had been feeling, made it seem like she wanted to do it. Mia was a sexy Hispanic woman, about 5'4 with dark hair and complexion and noticeably large breasts, and a thick ass. Both Mia and Alexa dressed conservatively at school, so at home they both drifted toward more sensual outfits. Mia frequently wore yoga pants that seemed almost painted on, accentuating her thick butt and highlighting her thin waist. I had certainly fantasized about her, plus it had been a while since Alexa and I had been intimate, so maybe this was just what we needed.

The idea didn't take me by surprise. We'd all been flirtatious with each other and increasingly so after finding out about their lifestyle. The night seemed particularly charged with sexual tension, so, when Chris asked if we had made a decision I just said, "yes."

"I am sorry, Babe... I just thought you wanted to do this."

"Well... yeah, I guess I do, I just thought we would have talked about it first. I mean this is a pretty big deal, don't you think?"

"Of course it is," I agreed.

Alexa exhaled sharply, "Look, you and Chris and Mia have all been with other people, but for me... you're the only one I've ever been with, this is all so new to me."

"But... I don't want you to regret not doing this and then resenting me for getting in the way. I just want you to be happy again." I sighed with vulnerability.

"What? What does that mean?" Alexa snapped.

"I know you love me, but, it's obvious you aren't happy, and I am not even sure why. But if this will help you feel... I don't know...desired, or sexy, and happy again, I am all for it." I let that sink in for a second,

"That and Mia's pretty hot," I chuckled, breaking the tension.

"Oh shut it!" She playfully snapped. "But seriously, you're a little drunk and a LOT horny and may not be thinking clearly. I know we've been busy and it's been a few weeks since we've had sex, I am just afraid once we get home we're going to fool around and once you've cum you're going to regret this and want to back out."

"Why would I be the one to back out?"

"This is what I mean, you haven't thought this through. Are you telling me you won't feel even a little jealous watching me with Chris?" She asked as she continued to drive.

"Honestly Dan, take a second and think about what that's going to be like in real life, not like in some porn you've watched, but to see Chris's hands all over my naked body, to see him kiss me, and to watch as I take his big cock in my mouth, and finally as he slides his big dick inside your wife." She huffed, turning herself on as she talked.

"Fuck Baby, that's hot!" I reached over and groped her breast.

"You don't think you'll be even a little... embarrassed?"

"Embarrassed? Of what?"

"God, you're going to make me say it aren't you?" She sighed. "Babe, you're kinda small."

There it was. The truth neither of us had wanted to say aloud. The elephant in the room--or, more accurately, the mouse between my legs. I had always feared what she was saying was true. I'd hoped that maybe compared to real life guys I wasn't far from average, or more accurately I was hoping the difference in size wouldn't matter. After all most people couldn't tell the difference between 4 and 5 inches.

At the same time, I'd seen the way Alexa looked at Chris sometimes, her gaze lingering just a little too long at the sizable bulge in his pants. The way she'd touch him, like it was taking all her effort to not sink her hand between his legs. But I wasn't ready to concede quite yet, I didn't want to go down without a fight.

I knew she was right, but I acted indignant, "I am pretty average and odds are Chris is too, you know that the connection between height and penis size is a myth right?" Chris is lean and tall, standing at 6'4 with long lean muscles like a basketball player. I was hoping he was shower and didn't get much larger erect.

"God, Babe you are not average! Mia and I have been talking about you for awhile now, we share information. She helped me understand that you're." She paused, and changed her tactic. "Dan, that dildo I got," Her voice calm and her words slow and drawn out. "That one's on the top end of average. It's 6 and a half inches long and 5 inches around, and it feels a lot bigger than you."

"No, the average is like 5 and a half inches," I corrected. "You know those guys in porn are abnormally huge, plus the girls are tiny with little hands." The more porn we watched together the more she was becoming sensual, more curious, and frequently pointed out size differences, sometimes pointing out large breasts or big asses, but mostly focussing on dick sizes. She seemed to get turned on the most by large dicks, and the more she did it, the more I loved it and looked for big cock porn. But, I also assumed it was like me getting excited by larger breasts - sure I liked watching them, but I was equally satisfied with Alexa's handful.

"Okay, let's say you're right. That's still a full inch and a half longer than you." Alexa shared as she pulled up at the red light. About a year ago we had been fooling around and Alexa pulled out a tape measure and said she wanted to measure me. I thought it was pretty hot at the time, she worked me with her mouth until I was fully erect and then placed the tape down my penis, she even pushed it into me pretty hard, we both looked down and saw the reading, 4 inches long, a little less not pushed in so hard.

Then she wrapped it around me and measured again, my girth was also about 4 inches, maybe a little less.

I didn't think much about it at the time, early on in our relationship Alexa spend easily 20 minutes just examining me, pulling, pinching, and rolling my balls in her hands. She was a double major in education and biology, and found a weird sense of delight in trying to understand my anatomy. I am not going to lie, I loved it, I loved having her hands all over me like that.

I knew I wasn't big, but I didn't think I was that much smaller than average real dicks. Even, the handful of times I'd seen other guys naked, it's not like they were erect. Flaccid my dick looked about the same, and I had almost convinced myself that any size difference was a matter of physical perspective, that looking down at your self is always going to give you skewed estimation.

"I don't even know what to say," I confessed. "Is this why you told me you've been regretting not doing more before us?"

"I don't want to hurt you, but that's certainly part of it. The more Mia and I talked, and the more I researched and the more we watched porn, the more my curiosity has grown. But, to be completely honest with you, I just don't feel like you've been as invested in my pleasure as you have your own. Can you think of a single time that you initiated using the dildo on me? What about the vibrator? I can't. I've always had to ask for it, and I don't want you to feel bad, but I have needs too."

"Wait... did you tell Mia I have a small penis?" My breathing increased as my face burned with humiliation. Why was this turning me on so much?

"I didn't just blurt it out at her in the hallway at school. She was telling me about how sore she was after a long weekend of sex, and I told her I never had that problem. We got to talking and well, she brought it up. She said she just assumed you were a grower by how little you filled out your swimsuit. That's when I told her." She let that sit for what felt like 5 minutes with neither of us saying anything.

"I still enjoy having sex with you." She finally shared breaking the awkward silence. "These are all the types of things we should have talked about, but every time I tried you just shut me down."

"What exactly did you tell her?" My heart was racing and my consonants crisp.

"I told her the truth, you're 4 inches long and 4 inches round." She responded with a cold analytical tone, she had always been a true science nerd. "You know Mia's been with a number of guys. She says her average is probably 6-7 inches."

I could feel the redness in my face and my dick leaking forming a dark wet spot in my pants. "What about Chris, do you know his measurements?"

"Yes. I'll tell you, but you have to promise to do something for me first, and you have to promise not to back out of this."

"Okay."

"You also have to promise that tonight and the rest of the week you will do what I say." She said with a playfully kinky tone. "And, you have to prove to me that you care about my sexual pleasure at least as much as you care about your own."

"Damn, Alexa. I like this side of you." I tugged at my hard dick pressing against my jeans. "I'll do whatever you say."

"I hope so because like it or not we're doing it. You're the one who told them we would join them next week and we're not backing out. Understood?" She barked using her teacher's voice.

"Yes, Mam." I looked around and noticed we weren't heading home. "Where are we going?"

"Just sit tight, you'll see." Minutes later we pulled in front of a run-down shopping strip with a nail salon, check cashing service, and at the end was a brightly lit adult novelty store. "Stay here, I'll be right back."

She hurried inside the novelty store, and my mind raced wondering what she was getting. Maybe a new toy to add to what we already had. Or perhaps a sexy outfit for next week. My dick was throbbing.

Moments later she came out holding a big black bag. She got back in the car and told me not to look inside and that we'd finish this conversation at home, but from the weight of the bag, it seemed like she bought several new things.

Once home Alexa told me to go to our bedroom and get undressed. I stripped down, my dick swollen hard, seconds later she was standing in front of me with the black bag and a cup of ice water. She wrapped her hand around my stiffy giving it a few pumps, then grabbed her 6.5-inch dildo from the drawer and held it against my 4-inch dick.

"See babe, a few inches makes a huge difference," Her eyebrows arched ever so slightly, a knowing smirk playing at the corners of her mouth. She didn't say a word, but the glint in her eyes and the way she tilted her head spoke volumes as if to give me space to realize what she had known all along, my penis was in fact small.

My face burned as the truth settled in, the heat creeping up from my neck to my ears. She peered into my eyes waiting for me to respond "I...well, maybe it is small," I muttered. The knot in my stomach tightened as Alexa smiled, looking down at my little dick.

"Now, come," She led me to the bathroom and instructed me to turn around and put my hands behind my back. I heard her fumbling with the bag and then felt the cold metal of cuffs clamping down on my wrists.

I turned back around fully naked, with my 4-inch dick throbbing for release. Alexa had a huge smile, and she held a small box in her hands.

"You're so cute," She giggled, teasing the sensitive underside of my dick with her finger. "Are you sure you can handle knowing how big Chris's cock is?"

"Yes, honey. Tell me." I pleaded.

"Not yet." She took the cup and placed it under my dick pushing the cup up over my dick and balls soaking me in the cold water and splashing water on the tile floor. "We have to get rid of that little boner first." She smirked.

"Babe!" I shivered, she submerged my junk for what felt like 3 minutes as my erection deflated and continued to shrink down to almost nothing. She put the cup on the counter, sat down on the edge of the bathtub, and pulled me to her. She dried me off, examining my shriveled dick that was little more than the head covered by some cold tight skin.

"I've never seen it so tiny," She chuckled.

"Now will you tell me?" I must've sounded pathetic.

"Oh, I am not done with you, my little man." She opened the box, Inside was a small cock cage. We had watched a few videos of male chastity, but this one seemed much smaller, just a short metal ring with a tiny metal cap to keep the penis secure.

"You're not seriously going to make me wear a cock cage?" I snorted.

"Hmm, I think it's more like a mouse house than cock cage don't you think?" Her giggle echoing in the tiled bathroom, while holding it up and showing me how small it is. "I told the girl at the store you have a 4 incher, she said this is the smallest they carry in store, anything smaller would have to be specially ordered." She winked, growing more brazen.

"I want to keep you excited, and it's one way you can prove to me you care about my pleasure. So you can either let me lock your tiny penis up, or I'll just do it anyway." The sound of the word tiny sparked my interest and turned me on even more. She had never talked like this before and rarely had used anything other than "thingy" in talking about my penis.

"God, this is so hot baby. Do it." My pulse raced.

"I am glad you like it." She smiled. "But I want you to ask for it, ask me to lock up your little mouse."

"Please, Alexa, will you lock my little mouse in its house?" I squirmed. It took her a few minutes to figure it out but she got it on me and I watched as she slowly compressed my penis down to a small button, then she put the key around her neck on a string.

"I knew you'd be into this." She licked her lips, "Don't think I haven't noticed that every time we watch porn together it suggests cuckold videos. Tell me the truth Baby, do you stroke it to naughty cuck porn when I am not with you?"

"Yes..." I confessed my breathing tight.

"Now, what did you want to know?"

"How big is Chris's cock?" She made me ask again.

"That's right... Well, of course, I haven't seen it yet. But, according to Mia, he's about eight and a half inches long and just over six inches around." She beamed and my heart skipped a beat.

"Holy shit!" I cussed.

"You know what that means? He's literally more than double your length." She laughed.

"Now turn around," I hesitated, and she flicked my balls. "Turn around."

She unlocked the cuffs and told me to take a shower, smacked my butt, and left the room. I did as she said, and as I waited for the water to heat up I played with my caged dick, examining it and looking at myself in the mirror and saw just how small it was. I gave it a few good tugs and realized it wasn't coming off without the key. I got in the shower and washed my hair and body, I kept waiting hoping she'd join me. But then I heard her,

"Come to the bedroom when you're done." I quickly got out and dried off. I opened the bathroom door to find Alexa on the bed wearing a cute but simple pink camisole top with pale blue cotton panties.

"God you're sexy," I panted, straddling her on the bed embracing her and kissing the tops of her soft breasts as I knocked at her entrance with my new metal mouse house.

Alexa was enjoying the attention and pushed my shoulders down her body. "Go down on me," she commanded with a breathy hum of pleasure. She purred, arching her back slightly. "Show me how much you want me. Show me you don't just want to fuck Mia and you're willing to watch as I am pleasured in new ways, by a man with a much larger cock."
