Erin's Fitness Transformation

All was forgotten though when Kris slid a few fingers into her quim as he filled her arsehole with his cock.

"James mate," Kris said, "If I could lick her cunt I would, but I can't, so be a gentleman and lick this fine lady's cunt while I fuck her in the arse."

"It would be my pleasure!" James responded and leant forward between Erin's legs.

The moment his tongue touched her clit Erin came again.

"Fuuuuuuucccccckkkkk!!!!" she screamed.

"Told you your head would spin thanks to the special class, didn't I?" said Eve.

"And how!" Erin looked over and saw that her friend was being fucked by both Markus and the last of the trainers.

Eve had Markus' cock embedded in her arse, while the other guy was ploughing her cunt.

"Wow!" said Erin. "That looks like fun."

"Christ Erin!" exclaimed James. "What happened to the timid woman who walked into this room only half an hour ago?"

"You flicked a switch," replied Erin. "Being here, with all you guys, you've made my wild side come out."

"Well I'm very glad we managed that."

"Enough talk though, I want to feel two cocks inside me!"

"No trouble. I think it must be Paul and John's turn now."

"Hell yeah!" exclaimed the two men whose shafts were in Erin's hands.

Kris pulled his rod from Erin's tight hole with a bit of a pop and she stood on slightly shaky legs. Paul sat next to her and she made to straddle him.

"Face me Erin, I want to suck on those beautiful tits."

With her face to him she lowered herself onto his nice fat erection, sighing as it split her open. As she bottomed out Paul latched his mouth onto her left tit and she felt John spreading her arse cheeks wide.

"Mmmmm, Paul that's nice. Come on John, stick that thing in there so the two of you can fuck me."

Seconds later she felt John's cockhead piercing her sphincter.

"Oh my fucking GOD! That feels so good, I'm so full! A cock in my pussy and one in my arse! I need to do this more often!!! Come on guys, fuck me hard!"

The two men quickly got into a rhythm and began pounding Erin's holes hard. Her moans were getting louder until James cut them off by pushing his shaft between her lips. She swallowed well over half in one go and began to swirl her tongue around it before allowing him to withdraw. On the second go she took two thirds of his long cock into her mouth.

"You're one talented slut you know Erin, you're going to make me cum already!"

He thrust a third and then a fourth time into her warm mouth before he felt his cum making its way from his balls. James held the tip of his dick in her mouth as the first spurts shot from the end, pumping his juice into her welcoming mouth before pulling out and firing the rest of his load over her pretty face.

"Fuck yeah," James hollered out as he splattered her face with his man jam. "Eve, thanks for bringing her here."

Eve couldn't answer because now she had Kris' cock in her mouth and was airtight.

James took the back of Erin's head and pumped his cock a few times into her mouth as he came down from his high. He scooped up a dribble of cum off her her face with his knob and fed it to her.

Erin had swallowed the load whole, something that she never did at home, or had ever done before. This was certainly a night of firsts for her.

James rested back and watched Erin as Paul and John pounded her two holes with a desire unwritten.

He took in Eve being filled with cock and realised that for Erin to be truly one of the team, Markus and Tom, the final trainer, would have to fuck Erin too.

"Tommo, Markus!" he called out, "You're going to have to have a piece of this, so save yourselves."

"Hell yeah," Tom called out with a look of pure glee. "I want her arse."

"Oh god," moaned Erin, "More cock?"

Eve popped Kris' cock out of her mouth and smiled at her new apprentice.

"Of course you are, slut," she said, "And you've got one or two more things to do tonight as well."

Erin couldn't imagine what Eve could be thinking about. She'd been fucked by three men all at the one time, had swallowed a load of cum and had taken two cocks up her arse already, there was little more that she could even comprehend.

Markus whipped his cock out of Eve's arse allowing his stunning blonde girlfriend to rise unsteadily off Tom, who subsequently rolled over and stood up.

Markus whispered something to Eve who just nodded and smiled before moving over behind Paul who was pounding Erin's arse.

Markus wrapped a towel around his waist and stepped out of the spa and the rush of cold air brought Erin's attention.

"Where?" she managed to say before Kris plugged her mouth with his prick.

Erin began tonguing and rubbing Paul's and John's balls as they fucked the young nymphette, and it was John who exploded first.

"Fuck, fuck, fuck," he softly said as his ball bag shrunk and his jizm shot into her.

Erin couldn't believe the feeling of his wet, slick cock pressing up against Paul's through the thin membrane between her holes. Her orgasmic flow returned when Paul buried his cock deep in her passage, and grabbing her long damp hair like a rein, he shot his load deep inside her.

"Oh fuck yeah, baby, fuckitty fuck fuck."

Moments later the air hit her again as Markus walked back into the room with a foam mat and lay it on the floor.

As Paul and John slowly finished shaking and cumming, they both peeled themselves off Erin and fell back into the spa.

Gently Eve took Erin by the hand and gathered her in her arms. Without warning Eve kissed Erin on the lips and met no resistance whatsoever, in fact she was met by a darting and exploring tongue and wandering hands.

With the two women putting on a show all of the guys were able to catch their breath slightly. "How did Eve know that Erin would be into this?" Paul asked Markus.

"To be honest mate, she didn't. She just took a punt that somewhere within that somewhat reserved shell there was a tigress waiting to come out. I mean, it seems that sometimes when they were chatting about sex Erin would get really caught up in something before catching herself and stopping, so Eve just thought she'd get us to try pressing a few buttons in a more physical way."

"Well thank fuck she did!" said John. "Erin's one of the best fucks I've had in a long time."

They heard a chorus of moans from the girls and saw that Erin now had one of Eve's firm tits in her mouth. They were also each probing at the other's sticky cunts with a couple of fingers. The noise grew to a crescendo as both Erin and Eve came hard.

"Come on then Erin," said James, "time for you to give Markus and Tom a demonstration of your skills."

"Hell yeah!" said Tom lying down on the foam mat that had been brought in just before.

"Gladly!" replied Erin walking over to join him. "You were the arse guy right?"

She stood over Tom and he got a great view of her tight arse cheeks descending. Holding his shaft in his fist he guided it into her anal canal.

"Mmm, that's feels so good Tom!"

"Fuck me Erin! You've had two dicks up there already tonight and you're still as tight as hell!"

He supported her weight as she lowered herself down until she bottomed out. Lying back Erin spread her legs wide.

"Come on then Markus, why don't you give me a bit of what Eve's been getting from you."

Markus didn't need asking twice, he knelt between Erin's legs and with one powerful thrust rammed hid rod home hard.

Erin screamed out in pleasure as his fat shaft thudded against her cervix.

"He's good, isn't he?" said Eve as she came over to join the threesome.

Markus and Tom were drilling into her holes, which was driving Erin wild. She was surprised though when Eve manoeuvred herself so her pussy was in front of Erin's face.

"Why don't you put your tongue to good use and clean me out before I get my next dose of cock."

'Yet another first,' thought Erin as she craned her neck up to reach the pink lips above her. She felt Eve's hand on the back of her head, supporting it, and the other woman also crouched lower to allow Erin better access.

Erin eagerly attached Eve's love tunnel, her tongue probing deep into the wet folds.

"Jesus fucking Christ Erin! For a first timer you sure eat pussy well! Oh fuck yeah, that's it, stick your tongue deeper!"

Erin obliged, worming her tongue as deep as she could. Her body was still being pounded by the two guys and caused her nose to press into Eve's clit. Eve let out a cry and her cunt juice squirted all over Erin's face.

"Oh WOW " exclaimed Eve. "Now that was a first for me, squirting like that. Now who's up for filling me up?"

Kris and Paul practically rugby tackled her to the floor in their haste to get a piece of her and within moments she had Kris' shaft in her back passage and Paul's in her juicy cunt.

John had a choice of Eve or Erin for some oral pleasure and it was the brunette Erin whose mouth he filled.

"Full again, Erin," James said as he watched from the benches, slowly stroking his cock back to hardness. "How's that arse feel Tommo? Nice and fucking tight?"

"Fucking magic, mate," Tom cried out, "She's so fucking hot."

With Erin dazed in ecstacy and full of cock, James shuffled through his clothes and pulled out his phone. With a wink to Eve, who'd seen him get it out and turned away from the camera letting her blonde hair obscure her face, he set the camera to silent and began firstly taking some stills, followed shortly after with a video of the group.

With the phone obscured by the towel he walked around them all, particularly Erin as she screamed in orgasmic bliss as the three cocks fucked into her.

James bent down next to Eve and whispered.

"Shall we let him know now?"

Eve looked back over her shoulder at Erin who was being relentlessly fucked by the three studs.

"Send one to my phone, I'll forward it to him," she said.

"Is he still outside waiting?" Kris asked.

"Yeah, poor bastard," Paul answered.

"I have an idea," Eve said, "Send it to me and I'll get it sorted."

James swiftly sent an image to Eve, who although was enjoying being double-penetrated, had an important job to do.

Kris and Paul knew that they'd get their fair share of cunt, so a small delay was of no real concern.

"Just keep fucking her," Eve ordered them as she quickly pulled her swimmers back on and wrapped a towel around herself. "I'll be ten, if that."

Apart from the repeated effect of the cool air calming her skin, Erin was immersed in a world of carnal desire. Suddenly she had six guys all rubbing her sweating skin, their fingers tweaking at her nipples, cocks being fed into her mouth, her clit being licked and flicked as orgasm after orgasm rolled into one gigantic wave of bliss.

They guys flipped her onto all fours and took turns in her pussy and arse, either cumming in her mouth, over her face, or shooting an arc across her arse cheeks. As they came the guys would shuffle across the floor and either sit and watch the stayers, or sit back in the spa.

Soon the door opened again and shortly after Erin was being roused out of her torpor by Eve who was sliding underneath Erin's torso, aiming for her well-fucked and cum-filled pussy.

As James fucked Erin's arse, Eve licked her clit and tongued her hole, sending shards of deep pleasure through her.

"Fuck yeah, fuck," James cried out as Eve sucked his ball bag, making him cum once again that evening. He whipped his cock out and fed it directly to Eve who was now enjoying Erin's expert cunt licking.

Eve looked up at the last guy standing behind Erin, waiting for his turn in her arse.

He dropped to his knees, slid his dick into Eve's mouth and dribbled a glob of spit down into Erin's open and well-fucked arse.

With great ease he slid his cock all the way in, soliciting a nice squeal of delight from Erin as her back passage was filled once again.

Eve shuffled out from under Erin and kneeling next to her she lifted Erin's exhausted face and told her to open her eyes.

"Look around you Erin, how many guys can you see."

Erin counted out the three guys on the bench, the one standing and the two in the spa.

Somehow, another guy was now fucking her with a gusto in the arse.

Eve knew that Erin was aware that there was someone new, but really had no idea.

The guy nodded to Eve and smiled at the woman responsible for transitioning the woman he was fucking from being his devoted wife, to being the fuck-slut he'd always really wanted.

"Turn around Erin, look who we have for you."

When Erin saw her smiling husband Steve beaming down at her she squealed. Torn between guilt and ecstasy at having been caught out she could feel an orgasm building, but tried to break away.

Steve's grip on her waist was firm as he made sure his cock remained wedged deep in her arse.

"Oh my God! Steve! No! You weren't meant, I mean, I didn't want to..."

"Babe, babe?" reassured Steve. "Calm down, it's all good, enjoy the ride and in fact, enjoy another cock." He nodded to Kris who within seconds was on his feet and pushing his shaft between Erin's lips.

"You're so fucking hot," said Steve as he drilled his wife "I've known from the first time I spoke to Eve what a fucking hornbag you really were. She told me about the conversations you two had had, and how much you wanted to fuck James. So I told her to make sure you got as much as you wanted. Looks like she did a pretty thorough job!"

He winked at Eve as his orgasm hit and he emptied his sack into his wife's bowels.

Pulling out he walked over to where the other woman was sitting.

"Ok boys, do your best. Let's see how she handles the six of you at the same time, while I get a taste of the lovely Eve here."

As the other guys rushed to surround his wife, Steve sat down next to Eve.

"Guess I owe you 50 bucks then," he said, "I never thought she'd go all the way."

"I told you she had it in her," replied Eve, taking his limp dick in her hand. "She just needed the right setting."

"So it seems. Tell you what, double or quits, if she takes two in the top and three in the bottom, however that may be, all bets are off."

"Mmm, kinky! I wouldn't put it past her the mood she's in, but your on. Either way I'd like to see her try."

Eve walked over and whispered the new stakes into Markus' ear before returning to Steve.

"Now let's see if I can't get some life into this thing so you can fuck me while what's left of your wife's virtue gets totally removed!"

Steve groaned as her warm, soft lips wrapped themselves around his cock and thought back to the first time that Eve and him fucked, some four months earlier with Markus and Tom as back up.

That tryst at Markus and Eve's home led to Steve 'Travelling for work' on many an occasion, but it was Eve who initiated Erin's transformation, a mission to bring her into their sex-filled lifestyle.

A mission now fully accomplished.

Markus stood back considering the situation in front of him. Steve was enjoying having his cock brought back to life whilst the other five guys were either having their dicks sucked by the now squatting Erin, or were standing around pulling on their cocks.

The spa room wasn't the best venue for a gangbang so he quickly grabbed his gear on and headed out to the main stretching and group class room which was now absent of anybody looking to exercise.

In the store room were piles of rubber mats and rectangular foam blocks used for sitting on or step classes, he wasn't sure which, but for tonight they'd be perfect for his mission, to see Erin with two cocks in her mouth, one in her arse and two in her pussy.

Awkwardly, due to their size, Markus managed to drag the three pieces he collected back to the spa room.

On entering Eve was now being skewered by Steve and Tom whilst Erin was being well fucked in the arse by a rejuvenated Kris.

He placed the large rectangular block in the centre of the room and piled the other two pieces of foam on top.

As much as he didn't want to interrupt the fuck that Erin was enjoying, he had no choice.

"Okay babe," he said as he broke the trance that she was in, "Let's try something new shall we?"

Erin nearly slapped him, not at the suggestion of more fucking, just that everything so far that night had been new.

"Whoever wants to fuck her arse next," he tapped the foam, "Climb aboard."

There was a scramble of male bodies, but it was John who muscled the others out of the way.

Eve, now free of the prods of Steve and Tom, took John in her mouth, sucking his thick cock until it was glistening and hard.

"Now babe, sit on that cock, facing me."

Erin climbed on the block and eased herself down, emitting a light squeal as her arsehole engulfed his thick cock.

Steve couldn't believe the transformation that his wife had undertaken in just a few hours.

Markus surveyed the room of cocks and selected Paul and James for the next part.

"Paul, mate, you're athletic, climb up here and kind of put one foot here," he patted the block next to her waist, "and the same on the other side."

Paul did as best he could and his powerful thighs were up for the job. Squatting back he slid his cock into the delightful Erin as she once more crooned gently in a euphoric splendour.

Eve began massaging their balls as they began pounding into her.

"Tom and Kris, grab a chair each and shove your dicks in her dirty mouth."

Eagerly they climbed up and even more eagerly Erin consumed their hardening cocks. "Eve, get us hard as we take turns fucking that pussy next to Paul's."

Eve dutifully dropped to her knees and with two hands flying, and her mouth in overdrive, she had Markus, James and Steve rock hard and ready to roll.

"She's your wife." Markus said to Steve, "You can have the honours."

The height was perfectly judged by Markus when he constructed the tower of power, and with very little effort, albeit with a gasp of surprise from Erin, he slid his knob-end in next to Paul's, fully stretching and expanding her cunt to an extent that she'd never felt before.

John kept himself still as Paul and Steve tried to fuck her by alternating turns in her cunt, her pussy juices flowed freely and they were enhanced by the cum that was oozing out of the guys' cocks.

Seeing that things were going well at one end, Markus moved up to Erin's head. She had James and Tom's shafts in her hands, while Kris fed his into her willing mouth. Markus nudged Kris to one side and placed his cock head alongside that of the other man. As best she could, Erin wrapped her lips around the two knobs before her. It was a bit of a tight squeeze, so they pulled out and allowed her to orally pleasure them in turn.

Steve was enjoying the strange tightness of his wife's cunt caused by the fact that both John and Paul were penetrating her at the same time. He glanced briefly to one side and saw Eve sat by herself taking the whole thing in, three fingers buried deep in her pussy.

Pulling out of his wife he looked at the four men further up her body.

"I can get more of this slut later, any of you want another go be my guest!"

Tom jumped at the chance and as he began to squeeze his shaft into Erin's already occupied slit Steve walked over to Eve.

"You look a bit lonely there," he said, "and seeing as how my wife is being very well taken care of I thought I'd come and take my pound of flesh from the woman that turned her into a slut."

"Mmm, sounds good to me." Sighed Eve. She added a fourth finger to her wet snatch. "I remember the first time the guys did that to me. I was so full it hurt, but it felt fucking amazing. Erin's taken to it like a natural!"

"On your knees!" commanded Steve.

Eve positioned herself on all fours facing the cluster fuck that was still taking place in the middle of the room. Steve knelt behind her and in one swift movement rammed his cock home in her cunt.
