My wife has a dress that comes with an invitation. 

It’s black and slutty, and every time she puts it on, I know the rule: I can fuck her wherever and whenever I like. It’s a game that has led to delicious dinner dates, engaging movie-going experiences, and occasional fun walks in the park. 

Last Friday she wore it to a party. 

An old friend invited us to their place as a post new years celebration, so we could all enjoy ourselves after everything else in the city calmed down. We dressed up, me in a suit and her in that gorgeous dress, and the rest of the guests took the opportunity to do the same. 

Everyone looked beautiful when we walked in. 

My mind, however, was stuck on the dress. Kelly’s ass looked incredibly in it, and it was hard not to imagine all the times I had taken advantage of our rule. As we mingled, I couldn’t keep thinking about lifting that tight black dress, bending her over a sink or a table, and fucking her for all I was worth. 

Some time, maybe a few hours into the party, I lost her. We often separate at events like that, and it’s not unusual for us to wave at each other from across the room as we talk to separate friends and enjoy ourselves. 

But as I sipped a glass of champagne, I realized I hadn’t seen her in close to a half hour. 

I looked out on the balcony, but she wasn’t there. I checked the downstairs bathroom, but no luck there either. Had she somehow wandered upstairs? 

The lights were low on the second floor of their massive duplex apartment, and as far as I could tell, it was devoid of party-goers. I peered into the office and the upstairs bathroom before I finally cracked the door to the main bedroom. 

I could make out a form on the bed in the dim light. Slightly concerned that Kelly had drunk herself to sleep, I entered as quietly as possible. Sure enough, my wife was lying on her back on their giant king-sized bed. 

She was not, however, asleep. And more to the point, her dress was hiked up around her waist, and even in the darkness, I could tell her lipstick was smudged.

“Kelly?” I said as I approached. “What the hell is going on? Are you okay? Did something happen?”

She reached a hand up and pulled me into a sticky kiss before saying a word. 

“I’ve been a bad girl,” she said, finally letting me go.

“What does that mean?” I asked, struggling to believe what I was seeing.

“It’s the dress’s fault! I’m always horny when I wear this dress.”

“Well, I was planning on finding you and dragging you into a bathroom sometime tonight.”

“Someone beat you to it,” she said as she pulled me over her. I rolled next to her, my thoughts swirling as my cock grew hard. Was she kidding? It was not a funny joke.

“I thought the dress was for me,” I said, reaching between her legs.

Kelly swatted my hand away and then rolled over to straddle me. She pulled the straps of her dress down, exposing her perfect breasts, and her smile was dangerous. 

“Don’t be silly,” she said as she undid my suit pants. “The dress isn’t about you. It’s about me.”

“I don’t understand,” I said as she moved higher up my body. I could tell she had neglected to put on panties, but that was most often the case when she wore “the dress.” Easy access was paramount.

“When I wear the dress, it means I’m fuckable,” she whispered as her thighs closed around my head. “It means I won’t say no. To anyone.”

And then, as she lowered herself down, her pussy now inches from my face, I felt something drip onto my face. 

“And tonight, it just happened to be your friend Peter who took advantage of it.”

Before I could say a word, my wife sat on my face as I ate her cum-soaked pussy for all I was worth. She reached behind her with one hand to stroke my hard cock as she rode me, and I couldn’t help myself. 

“Feel how hard you are,” she moaned as she fucked herself on my mouth. “Almost as hard as Peter was when he followed me up here, pushed me onto the bed, and fucked me like a filthy little whore.”

“He didn’t,” I moaned, even though it was obvious she had. “Please tell me you didn’t.”

“He fucked me so hard,” she moaned as I tasted both their cum at the same time. “And you have ever been so turned on. He was so good, baby. His cock was so thick, and he was so strong and demanding. He never even said a word; he just threw me down, lifted my dress, and fucked me.”

I ate her with a vengeance as I listened to every word from her mouth. With her ass in both hands, I pushed my tongue inside her as I realized I was licking her where she had just been fucked. 

By one of my best friends. 

By a best friend who I might have gotten drunk with recently. An old friend, who I might have let slip that my wife has a “fuck me anytime” dress. 

As a hint of anger and guilt filled me, I tossed my wife to her back. I was in her in seconds, and even after my mouth, her pussy was soaking wet and full of another man’s cum.

“You are such a filthy slut,” I told her as I pounded into her. “Such a dirty girl letting my friend fuck you.”

Kelly moaned and wrapped her legs around me, but the smile never left her face. And as I fucked her harder and faster, she held me tightly and wouldn’t let go. 

“Maybe, if you didn’t want your friend to fuck me, you shouldn’t have told him about the dress.”

And then I was done, coming so hard I couldn’t see as I realized it was all my fault. Kelly clenched around me and started to come, and I couldn’t shake her words. 

“He made me come so hard,” she teased into my ear. “Right here, just like this. He fucked me with his thick cock, and came so deep inside me. Just like you wanted.”

“No!” I cried out as I collapsed against her, realizing that somewhere in the middle of her words lay a hint of truth. 

She kissed me and held me as I covered her body with mine. 

“You fucked me so much harder,” she sighed as I closed my eyes. “So much harder than normal.”

And just as I started to admit and accept that I had been the master of my fate, I heard the sounds of someone clapping their hands quietly behind me. 

“You get up to use the restroom for just a minute….”

Peter stood in the doorway to the bathroom with a smile on his face. He was fully dressed, but his hard cock stood at attention through the fly of his suit. His expression clearly showed that he had been watching and thoroughly enjoying himself. 

“Get over here,” Kelly said as I struggled to figure out what was happening and what I had done. “I told you he’d love it.”

And as she looked up into my best friend’s eyes, she reached up, wrapped her hand around his cock, and guided him to her mouth. I watched her lick him up and down before taking his considerable length down her throat with an expert touch. 

Still buried inside her, my cock twitched back to life instantly. And as I started to fuck my wife again, this time as she blew my best friend, I thought I heard a muffled laugh escape her busy lips. 

That fucking dress was going to ruin me. 

But until then….
