It was a rainy autumn Saturday, the ideal kind of day for a shopping trip. My wife and I decided to drive into the city for the day and pick up a few things.

We'd been married for a few years, and had been together for a lot longer. We'd met through an online dating app, and had been inseparable ever since.

I'm your typical 30 year old guy, with glasses, short light brown hair, and a slim build but with refined muscle.

My wife is a little younger, a brunette with long shoulder length hair and deep brown eyes. She is the epitome of 'curvy', with what can only be described as enormous breasts, and a firm but round bum.

We make our way into the city, and she drags me around the usual shops. She was looking for a new swim suit, and wanted my opinion.

I helped her pick out a few good options, and she makes her way to the changing room to try them on. I waited outside nearby, hoping she likes one so we can move on and pick up some lunch.

"Pssssst"

I look over, and the door to her changing room is slightly ajar.

"I need your opinion, come and have a look!" she whispers while beckoning me over.

I carefully make my way into the changing room, making sure none of the shop staff see me.

Inside is my stunning wife, wearing a two piece red bikini.

"Well, what do you think of this one?" she asks.

I scan her whole body, taking it all in. Her voluptuous breasts look perfect in the 36F sized red bikini top, showing an avalanche of cleavage. Her thighs looked sublime in the small red bikini bottom that adorned her crotch.

"Wow, you look... incredible". I could barely string my words together.

"Thanks babe, I really love it". She said smiling.

She looked down towards my crotch.

"Well, looks like you REALLY love it!"

I look down, and I had grown a massive boner, that had created a large buldge in my jeans. I had always had a decent sized dick, so it was difficult to hide when I was erect in public.

"I can't help it, just look at you right now!" I told her.

She chuckled to herself. She stepped towards me, and leaned over so that her breasts were touching my face.

"Does this make it better?" she playfully asked.

"No... but I'm not complaining." I replied.

She then reached towards my crotch and started rubbing the head of penis through my jeans. I started to moan in delight.

"Are you sure we should be doing this here?" I asked.

"As long as you quieten down, no one will know" she smirked as she talked.

She then carefully began to unzip my jeans, and slowly pulled out my cock. It was rock hard, and practically throbbing in her hands. She began to caress the head with her fingertips. I started to moan, I just couldn't help it. She quickly wrapped her spare hand around my mouth to muffle any sound. She continued to tease and stroke my cock, while precum began to dribble out onto her hand.

I reached around and unclipped the back of her bikini and it fell to the ground. Her large breasts were now within range of my lips. Her nipples were a light pink, and perfectly in ratio with the size of her bosom. I began to caress them with both my hands, while she continued to stroke my penis. Her nipples hardened, I couldn't resist slipping them in my mouth, and began to suck on them.

I reached down and slipped my fingers under her bikini bottoms. I began to slowly circle her clit, as her vagina gushed onto my fingers. Moans of pleasure escaped her.

All of sudden, there was a knock on the changing room door.

"Is everything ok in there?" a member of staff asked."

"Uhhh, ye I'm fine thanks, quite a bit to try on, will be a little while". My wife quickly improvised.

"OK....let me know if you need any help".

The disturbance hadn't phased me, and I reached down and almost ripped the bikini bottom away from her body. Her lightly trimmed bush was now visible, and she was completely naked, save a necklace that was around her neck.

"I want you now" I whispered in her ear. I bent her over, and slowly penetrated her from behind. My penis glided into her soaking vagina, and she braced herself against the changing room wall as I began to fuck her. I grasped my hand around her mouth to stop her moans from escaping.

There was a small square stool in the corner of the changing room, she beckoned me to take a seat. I sat down, and she climbed on top of me, carefully inserting my penis into her pussy. She began to grind on top of me.

Then, there was another knock on the door, but this time it sounded louder and angrier.

"Listen, people can hear you in there, if you're doing what I think you're doing, you better stop and come out right now!" The changing room attendant shouted.

I gave my wife a mischievous look, and began to fuck her, ensuring my whole shaft was moving in and out of her entire vagina.

"Oh my god, I'm gunna cum" she whispered in my ear.

I clamped my hand around her mouth as she came, muffling any orgasmic noises that may have come out. Her body shook and vibrated as she writhed in extascy. At this moment a wave of pleasure hit me. I quickly sped up my thrusts, and I knew I was about to cum. As I went as deep as I could go, a thick load escaped me, and waves of my cum filled her pussy.

"That's it, I'm unlocking this door right now" a voice from outside exclaimed.

The door clicked and swung open, and the changing room attendant stood there with her jaw to the floor, as she took in the sight of my naked wife on top of me, with my seed slowly dripping out of her pussy.

To sum up, it's safe to say we were never allowed to go into that shop ever again.
