This is not going to work, I thought to myself as I struggled to keep my junk contained within the bright pink bikini bottoms. The fact that I have a rather large cock didn't help, actually, that is not accurate it was probably only slightly larger than average when hard but it didn't shrink much when soft.
So no matter how I packed it in as soon as I moved something popped out. Now I know why men's trunks have strings

Then I had an idea.
The bikini bottoms were bigger at the back than the front. I quickly turned them around and yes there was now enough room for my meat and both my veg at the same time. The downside was that I now had a lot more of my ass cheeks on show but at least I would not be doing a Simon (The Inbetweeners reference)

Now I bet you were wondering why I am trying to put on a small pair of pink bikini bottoms in the first place, it all started about a month ago as a silly bet with my co-worker Jane.
We both work at a car sales garage and are fiercely competitive as to who can get the most sales each month and we would make silly little bets like having to buy coffee or wash the other person's car. This bet somehow turned out to be much larger

While we were on a works night out. She had been boasting about her next big deal and how it would dwarf my sales figures
I had a big deal about to come through too, so after a few typical bet suggestions we started goading each other and because of the amount I had drunk I can't remember whose idea it was but we ended up betting the loser would be gunged for charity

After a couple of weeks, my big deal was nearly finalised and I was ahead in overall sales, while Jane's big deal looked like it was never going to happen so I began to tease her
" I hope you're not going to wear that suit to be gunged in as I wouldn't want to ruin it" I joked
She laughed, and said "I hope you have a good dry cleaner as it won't be me getting my suit all messy"
The thought of taking a wet slimy suit to the dry cleaners gave me pause for thought.

"Look, to be honest, we both come to work in expensive clothes and I don't want to ruin your clothes so let's agree to wear something else, maybe gym clothes" I suggested trying to sound gracious

I could tell she was relieved by my suggestion but she still wanted to show some bravado "Fine if you are that worried about your suit you can wear your gym clothes when I get you messy"

This annoyed me more than it should have and before I could stop myself I blurted out "If you lose you have to wear that pink bikini you had on at the pool last week" I smiled and added "If you are so sure of winning it won't be an issue"

She thought about it and then said "Okay but when you lose you have to wear the Speedos that you had on." I was still confident that I would win and I didn't mind as I am fairly well toned and don't mind showing off my body so we agreed to the new terms the next day, our boss decided that to build some suspense he would keep the sales figures secret for the remainder of the month

I kept making good sales and at the end of the month, I was fairly confident I had won.
On the day the result was to be announced Jane and I started teasing each other again about who was going to get messy. She was so confident that she had won she wanted to increase the bet again and suggested I should wear her pink bikini instead
I didn't like that idea but I was sure that I had done enough to beat her. Then a wicked thought crossed my mind, surely she would see this coming.
"That's too much can I have a T-shirt too," I asked setting my trap
"Would you have let me wear one? No, you wouldn't have" she laughed
Time to spring the trap "Well it's only fair if I have to wear your swimwear if you lose you have to wear mine" I said and stuck my hand out.
She shook my hand and said "Deal"
I kept holding her hand and pulled her close "You should have agreed to the t-shirt " I whispered
It took a second for it to sink in then her face changed as she realised she just agreed if she lost she would be getting very messy while topless
"No wait that's not fair I didn't mean it" she protested.
"A bet is a bet" I laughed and walked off

As you can probably guess from the way I started the story. The sales figures did not go in my favour, and she had beaten me by a small amount but a win is a win.
A bet is a bet I remind myself as I look at myself in the mirror. The pink bikini top is stretched tightly across my chest and the bottoms that I have had to wear backwards show off almost as much of my ass as a thong would have.
Looking down I noticed that without a drawstring my package is pushing the bikini bottoms open and I can clearly see the tip of my cock. I wish I had some double-sided tape but it is too late now and besides, nobody will have this view.

I open the door to the toilets and walk out to cheers and Wolf whistles I decide I might as well ham it up and wave and bow as I make my way towards the small raised platform in the sales office where Jane is waiting gleefully for me,

I had expected to just sit on a chair while she poured a bucket of gunge over me, but apparently, the workshop mechanics on hearing about the bet had other ideas and decided to build a proper gunge tank
Jane wasted no time in escorting me in and sitting me down. I felt like grabbing her and shouting for someone to release the gunge, but as I said a bet is a bet, but just because I was willing to let her escape did not mean I was willing to accept my fate. So as the boss was giving a speech about how much money had been raised I quietly shuffled my chair forward slightly, so it no longer sat directly under the nozzle that going to cover me with the green slime.

It was time for Jane to pull the lever. Everyone shouted 3-2-1, Jane smirked as she pulled the lever The gunge rushed out of the pipe but as there was no dispersal mechanism a 2" stream fell straight down missing my head but I was not as far forward as I thought and the gunge caught my lower back and backside.
I was shocked at the force of the flow of gunge as it forced the thin pink material of the bikini bottoms open.
I very nearly lept from the chair when I felt the cold slime filling the bottoms and covering my ass.

When the flow of gunge had stopped there were boos and lots of disappointed faces in the crowd but none looked as disappointed as Jane's

I laughed and stood up allowing some gunge to drop from my bikini but I could still feel a large bulge in the back.

"Where do you think you are going, " Jane asked

"I have been gunged and now I am going to the shower" I explained

"You have not been gunged yet" She was mad

"Tell that to my bum" I joke as I turned to give her a view of my slime covered and slightly exposed butt as I walked off

"You are not going anywhere "She pointed at two mechanics and told them" Put him back in the tank and make sure it can't miss"

The mechanics grabbed me by the wrists and before I had a chance to struggle my hands were tied with cable ties to the roof beam of the tank.
A drip of green gunge dropped onto the centre of my head confirming that I was now standing with my hands tied above my head directly under the outlet pipe of the gunge tank

I had to stand like that while another batch of gunge was loaded into the tank which felt like a lifetime.
The small crowd of my coworkers were now calling for blood "gunge, gunge, gunge" they chanted as two large buckets of the same luminous green slime were loaded into the tank above my head.

"how come you have more slime," I asked Stan the workshop manager as he climbed down from the ladder after refilling the tank.

"Oh you're in luck," he said sarcastically "I placed the order for 20 units thinking a unit was a litre but it turns out it was a US gallon so there is plenty left over" He laughed.

I did a quick calc in my head 20 US gallons was about 75 litres so after filling the tank for the second time there would be around 35 litres left. I wished Jane or anyone else didn't realise that they could refill the tank again and still have spare.

"Ok, Jane let's get this over with before I lose the feeling in my arms" My arms were starting to ache as I was stretched fully upright with my feet only just flat on the floor. But that wasn't the only thing I was worried about losing, the now well lubricated bikini had been ever so slowly slipping down at the back. When I looked down I could see it still in place at the front but there had definitely been some slippage at the rear as I could feel at least an inch of my crack was exposed.
While looking down I realised that the small gap between my skin and the fabric that was allowing me to see my cock now looked like a chasm and that there was nothing I could do to stop the slime filling the front as it had the rear of the bikini. I was going to be lucky to get through this without exposing myself.

Jane leaned in close and whispered "You are mine now and if you are trying to figure a way to avoid your messy fate forget about it, if something goes wrong this time the workshop guys have said they have a drum of used oil that they will dunk you in"
Her warning hit home and I looked up to check I was dead centre and even though I was already stretched I straightened up a bit more, that shit would not wash off easily and I am pretty sure it is toxic. "Ok I won't move an inch, let's just get it over with"
Once again she grabbed the lever and counted 3-2-1
I held my breath as the gunge hit my head and made a perfect umbrella fanning away from me. This didn't last long and as the flow slowed the umbrella effect collapsed and the gunge was running down my neck and back and I could feel it sliding down my ass crack and refilling the bikini bottoms.

It ran over my shoulders and down my torso filling the bikini top and giving me a slimy cleavage. I would be finding this hilariously funny if it was happening to someone else but it wasn't.
Then the moment I feared arrived the gunge had made its way past my top and was flowing like a green stream straight for the gap. I felt it enter the front of the bikini bottoms slowly at first but as the flow from above decreased there was less wastage and the flow down my chest increased.
I felt the cool slippery liquid sliding down my shaft and start to pool around my balls then reaching between my legs to meet the gunge that had already assaulted my rear. The material of bikini bottoms was starting to sag and slide down and I could tell it was now only a matter of time before they slid off completely.

The slime cupping my balls and the sliding sensation of the material caused my dick to harden and I realised that the material was now caught on my hardon. Was it better to be naked and soft or have a rock hard cock sticking out like a tent pole? I am not sure which was worse but the feeling of the cool slime around my cock and dripping down my ass crack wasn't allowing me to choose. I was hard and nothing I could do or think about was able to change that.

The gunge had now stopped flowing from the tank but there was still some sliding down me so I wasn't safe yet and although the front was caught on my hard shaft I could still feel the back of the bikini getting lower.
This turned out to be a good thing as eventually with the front pinned in place the back got low enough that it started to empty. So I now had gunge flowing down my chest in the front of the bikini bottoms past my balls which caused my cock to twitch violently and I had to stop myself from coming.
It did also mean that the whole of my ass was now only covered by the green slime that was sliding off me and pooling at my feet but at least the back of the gunge tank was solid so nobody could see how exposed I was.

"I think someone enjoyed that" Jane said pointing at my crotch and my very obvious hadron
"Maybe he would like to do it again " shouted Stan "We have some more"
That bastard I thought how could he then I remembered he was workshop and workshop hated sales. I realised there was no mistake with the order and he probably didn't care which one of us got it or maybe he bought so much so we both would get covered in the slime

I think it was clear for all to see that it was only my erect penis that was keeping the small pink bikini bottoms from falling to the floorand it was very unlikely for them to survive another deluge
You would have thought that someone would realise what would happen and help me out but no the mob mentality kicked in when someone at the back shouted "Slime him again" In no time everyone was chanting "Slime him, Slime him, Slime him again"

As the tank was being refilled, I begged Jane not to do it again, but she was enjoying this moment, and nothing was going to stop her
I had one trick left to try "You know this is not too bad if I was doing it to you I would have done worse" I said to Jane
"What would you have done to me that is worse than this," she asked

"Well for a start if I had seen you tied in the tank with a bikini full of gunge I don't think I could resist giving you a wedgie to make sure this disgusting slime got squeezed as far up your ass as it would go," I said hinting at her to do it to me." but you probably won't want to get your hands dirty"

She took a step towards me and then stopped "Nice try but we both know that you are going to lose that bikini when the gunge hits you in a minute unless I pull them up"
"But I never agreed to get naked" I pleaded
"you should have thought of that before you tried to trick me into doing this topless." She replied "Out of interest if I had lost would you have made me do it"
I looked down "Yes" I mumbled
"good and I would have done it," she said which surprised me "A bet is a bet and if you make it one you need to be prepared to pay up, but my big deal had just come through when I made it so probably would have agreed to do it naked"

By the time the tank had been refilled, my cock had started to soften and it was barely able to keep the bikini bottoms up
Jane grabbed the lever for the third time and started to count 3-2-1
Again, the gunge hit my head and fanned this time as it slowed, the majority of it went straight down my chest. The bikini bottoms had no chance and were quickly washed off of the end of my cock and slid down my legs.
With my hands tied above my head, there is nothing I could do to protect my modesty. I groaned and looked up straight into the flow of gunge, as I didn't want to see the crowd, all laughing, pointing and pictures. I just wanted to disappear

At first, I felt so embarrassed I wanted to cry and run away, but of course, that was not possible, so I just stood there with the gunge flowing over my face, down my chest and over my exposed cork balls

Before the flow of gunge stopped I realised I had nothing to be ashamed of my body was toned, and my dick was more than big enough.

Then I thought about how funny I must look to everyone. I must have looked like a big green naked swamp monster.
This caused me to chuckle and before I knew it I was laughing out loud, and the gunge had stopped flowing

Jane came to the side of the tank and looked me up and down
"I am sorry that you lost your bottoms but I couldn't resist," she said
"Maybe I should help cover you up" and with that, she bent down and scooped as much slime into the bikini bottoms that now slid all the way to the floor.

While she was doing this her face was level with my hard cock and when she had stuffed as much slime in the bikini as she could she looked up and realised how close my dick was.
"Mmm very nice" she said licking her lips
I was just starting to imagine her sucking my shaft till I blew my load all over her face when she grabbed the sides of the bikini and stood up
I was shocked by the sudden motion and the gunge being squished into my ass. Jane was not happy with just a normal wedgie and continued to lift until I was forced onto my tiptoes
With an extra jerk, I was momentarily lifted into the air before the pink material ripped.
Jane ripped the bottoms off and swung them over her head splattering the crowd with slime
Jane then posed beside the tank holding the bikini bottoms at arm's length while I was once again naked

Finally, she cut me free and gave me a towel that I wrapped around my waist

Before I went for my shower I said to Jane, "That was fun but I want to make another bet. I bet you I sell the first car tomorrow"
"Your on" she agreed, "but what are we betting for"
"The other two buckets of gunge, of course," I chuckled "remember a bet is a bet" I called over my shoulder as I headed for my much neefed shower
