Gareth was in his late twenties and noticed he'd started to pile on the pounds recently. Unfortunately, he loved good food too much to trade it in for rabbit fare so that only left only one realistic option, exercise. He asked around at work and a couple of colleagues pointed him in the direction of a new gym situated at the edge of town. And it was at the gym that he first encountered Carly.

Carly was one of the instructors and an incredibly figure of a woman. Although only of average height she towered head and shoulders above other women Gareth knew in terms of sex appeal. She was in her early twenties, had shoulder length blonde hair and a figure that was seemingly made for the tight vibrant pink sleeveless unitard she wore whilst working out. Gareth was more than a little smitten with the instructor and looked forward to his sessions with her.

As Gareth became a regular at the gym, he gradually got to know Carly. She turned out to be very friendly and had a wicked sense of humour. He also discovered she wasn't above flirting with her clients to encouraged them to perform "just a couple more" exercises; something that he had experienced on more than one occasion.

Gareth arrived at the gym and made his way to the changing room to store his bag in a locker. He entered the gym proper to the accompaniment of a nineties power ballad which was blaring out of the personal address system. After some stretching exercises to warm up his muscles Gareth grabbed a couple of dumbbells and began his weight training.

He was sweating heavily as he reached twenty repetitions which of course was when Carly entered the room and spotted him. She sauntered sexily over towards him just as he was about to put the weights down and make for the showers.

"Come on Gareth, just a couple more" she said.

Somewhat reluctantly Gareth kept hold of the dumbbells and did another couple of lifts. Carly didn't look too impressed with his efforts, so he did a couple more before she gave him a big smile and a friendly pat on the shoulder. Then she disappeared off to motivate some other poor soul. Gareth took his chance to escape before Carly returned and made him do any further exercises.

Gareth quickly showered and put on a fresh set of clothes. He then made is way out of the gym and put his bag into the boot of his car before driving off towards the town centre to do a spot of shopping. As it was a midweek morning the town centre wasn't too busy, and he was easily able to park and get his shopping done in almost no time whatsoever.

So, as he had plenty of time on his hands and had done those extra exercises for Carly, he decided to pop into one of the local cafes and treat himself to something naughty; which turned out to be a large cappuccino with a dusting of chocolate powder on top accompanied by a generous slice of key lime pie. Gareth took his prizes over to one of the corner tables and sat down.

He took a sip of the hot coffee before turning his attention to the pie. Using a fork, he broke off the tip of the dessert and brought the morsel up into his waiting mouth. It tasted absolutely divine and so he began to break off and eat more of the pie. In fact, he had almost finished it when he became aware of someone standing beside him.

Glancing up Gareth discovered an incredibly beautiful young woman dressed in leggings and a vest top looking down at him with a coffee in hand. It was Carly. He felt himself begin to blush, although whether it was simply due to the presence of the woman of his dreams or the guilt over her discovering him stuffing his face with pie, he was unsure.

"May I?" Carly enquired indicating the chair opposite Gareth.

Not wanting to speak with a mouthful of dessert, Gareth indicated for Carly to sit down. As she did so he put down the fork he'd been using and tried to surreptitiously move the plate with the remaining pie to one side so it wasn't quite so obvious. But it was clear that Carly had already seen it and chuckled at his attempt to hide it.

"Aren't you trying to lose weight?" she asked.

"Well I… fancy a bite?" Gareth responded pushing the dessert towards her.

Carly picked up the fork Gareth had been using and used it to break off about a third of the remaining pie before popping it into her mouth. She let out a groan of pleasure as she ate the dessert fervently.

"This is so good," she said, "just a couple more."

And with that Carly ate the remainder of the key lime pie in two quick bites much to Gareth's amazement. She then returned the fork to the now empty plate and smiled guiltily up at him.

"Well that's one way to cut down on my calories!" Gareth stated.

"Oh, I'm sure I can think of something better" Carly replied cryptically.

Gareth had almost forgotten Carly's words days later when he returned for another session at the gym. But the huge grin the receptionist gave him and the sniggers from a passing couple of fellow clients made him realise that something was up. As he made his way down the corridor to the changing rooms, he noticed a small crowd of people standing around the noticeboard. They turned to greet him with cheers and laughter as he approached them.

On the noticeboard was a colourful poster announcing a bet between him and Carly. It challenged him to lose half a stone in six weeks. Should he fail he would receive a forfeit in the form of a pie in the face from Carly. However, if he succeeded it would be him pieing her instead. Gareth had just finished reading the poster as Carly walked up behind him.

"Told you I could think of something better" Carly stated.

Gareth stared at Carly in disbelief. Then before he could say or do anything, she bundled him into the gym where a set of scales had been set up. One of the other instructors recorded Gareth's current weight as the small crowd of clients watched on. Just as Gareth stepped off the scales, Carly mimed thrusting something into his face which provoked a round of laughter.

Still somewhat mentally off balance from Carly's challenge, Gareth wasn't quite sure what to do. He certainly didn't want to be humiliated with a pie in the face from her but at the same time backing down could be equally embarrassing with everyone thinking him a loser. That just left one alternative: lose the weight, win the bet and humiliate Carly.

Gareth immediately put thought into action as he did a quick series of warm ups exercises before heading over to the weight benches. Ten minutes later he was covered in sweat and both his arms were aching as Carly wandered by. She didn't utter her usual four words of encouragement, but Gareth did a couple of extra lifts anyway.

Gareth felt pretty confident as he walked into the gym on the day of his final weigh-in with his kit bag in hand. Over the past six weeks he'd stepped up his exercise routine and even gone as far as improving his diet. Yes, he'd been initially tempted by the displays of cream pastries in the local cafes but had managed to resist, mostly by picturing Carly grabbing the dessert in question and smashing it into his face.

However, as the weeks passed, he'd grown less and less afraid of Carly pieing him and more and more excited by the prospect of him pieing her. And he wasn't alone in looking forward to Carly's humiliation as many other clients at the gym, and even a couple of the instructors, would give him words of encouragement and advice to support him in losing the weight.

As Gareth approached the crowd of staff and clients waiting by the scales, he put down his bag and looked around for Carly. She wasn't hard to find dressed as she was in her usual figure-hugging sleeveless pink unitard. She gave Gareth a friendly wink as their eyes met. Then one of her fellow instructors stepped forward.

"I think we all know why we're here so let's get on with the weigh-in" the instruct said.

Gareth stepped on to the scales as everyone watched. He'd actually weighed himself yesterday so knew he'd made his target weight, but it was good to get confirmation, especially as the instructor announced that he'd lost ten pounds which was one more than he'd thought he had.

There was a round of applause for his achievement and many people stepped forward to congratulate him. It was during this time that he briefly lost sight of Carly and did wonder if she'd made a run for it. But as the crowd stepped back, he could see her standing to one side. She'd pulled back her blonde hair and tied it into a ponytail and was also wearing a baggy t-shirt over her unitard which he was slightly disappointed by.

One of the staffs put down a sheet of clear polythene sheeting on the floor whilst another placed a cheap looking plastic chair on in. Then all eyes turned to Carly. One of the male instructors lead her over to the chair and insisted she remove her t-shirt. She tried to object but both clients and staff started chanting "off, off" so she reluctantly took it off before ditto g down on the chair.

Gareth made his way over to beside Carly where he was joined by the receptionist who was carrying some messy ingredients. She handed him a large sponge flan case which she'd previously removed from its packaging. Then whilst he held out the flan case level towards her, the receptionist opened a carton of cold custard and poured it in.

There was laughter from the audience and Gareth thought he heard a gulp from Carly as the receptionist discarded the empty cartoon and took out a can of squirty cream. She then proceeded to cover all the custard with a thick layer of whipped cream before stepping back. Gareth took a firm hold of the flan case and asked for a five count as he noticed some people getting out their phones.

"Five... four.. three... two... one!" the audience called out.

Carly glanced up at Gareth as he took the custard and cream creation and thrust it into her face. The cream splattered all over her and the custard ran down her face and over her chest. With just one pie Gareth had reduced the beautiful gym instructor to a complete mess and he wasn't finished yet.

Striding over to his bag he reached in and removed a large cardboard box. Then opening the box, he took out two carefully stacked key lime pies and made his way back over to Carly. By this time Carly had cleared some of the cream and custard from her face and looked at Gareth as if she was about to question his intent.

"Just a couple more" Gareth explained.

Everyone burst out laughing, even Carly had to laugh as her own words came back to haunt her. Then once a modicum of order had returned to the room and it was clear that Carly wasn't about to object to her further humiliation, Gareth took the first pie and ground it slowly into her face. As the remnants of first pie fell to the floor Gareth took the second pie and smeared it up across her face before depositing the pastry case on top of her head.

As those watching laughed, cheered and took photos and videos with their phones Carly slowly stood up. She wiped the lime filling and cream from out of her eyes and turned her gaze upon Gareth. Then without warning she jumped him; giving him a great big hug, kissing him on the cheek and getting him more than a little messy in the process.

And then it was pretty much over. Carly heading off probably to get herself cleaned up whilst Gareth stayed for a few moments to bask in his success before picking up his bag and making his way to the showers.

The End.
