Sophie is a eighteen year old white girl in a long-term relationship. Her Boyfriend is Cory they've recently moved in together. The two now living together are arguing with all of the petty things amplified. The couple enjoy to make up with both having a active sex life.

Now Sophie is missing her own life where she would go to the gym when finished at work. Long days always on her feet being a hair stylist her only way of unwinding is a gym session. The gym sessions keeping her body in great shape Sophie's always receiving compliments. Especially about her Arse with the amount of squats it's big and really firm. Then with Sophie's natural large breasts 36 D cup will also bring so many other compliments.

This was the reason Sophie first met Cory he saw her wearing her gym wear and he was hooked. Now Sophie needed to get it back inside the gym for her Arse that is.

"Look Cory starting tomorrow I will pop into the gym again it will give us a piece of time to ourselves." sophie tells him.

"Come on Sophie that gym is miles away, we won't get any time together." cory then replied worried that his girlfriend is going to leave him.

"No there's a new gym around the corner I can get there in ten minutes Cory."

"Oh yes I know the one around the block called gym fitness Sophie." replied cory it's easy to have his girlfriend close by him.

"Yeah it's just been done up I can go to my salon and pop in for an hour before dinner Cory."

"Yeah I might come with you Sophie."

"No we need time apart Cory stop living in each others pockets." sophie shutting cory right down.

The following day Sophie cuts hair whilst her Cory worked inside a local garage as a mechanic before Cory heading home. Leaving Sophie to enlist in the new gym which is only walking distance from their flat. After work Sophie arrived at the gym and is met by a older black man. He tells Sophie is name is Charles he's thirty eight been a gym instructor since he's twenty. This being his second gym hopefully will be a big hit with the locals. One local he's hoping to be a really big hit was teenage Sophie.

Now Sophie signs up to a trial period then changed into her gym clothing. Tight crop top which emphasizes her large breasts it is the next part of gym gear Charles liked. Her skintight leggings she must do lots of squats to get that big Arse. It's lost inside with her both big cheeks they're not fat cheeks just really firm. She was five foot six blonde hair with piercing blue eyes if it wasn't for that Arse that drew attention it was her looks. Cory isn't aware how really lucky he's with his trophy girlfriend inside his bed.

That night the gym got really busy with all the opening night special offers. But now Charles as only got one new starter on his mind it gets even better watching Sophie squatting. Charles then sees her wipe off sweat from her big breasts. Then gets up to leave after over a hour of her squatting to keep that Arse looking good.

"Going really so soon Sophie, is there any problem?' asks charles he's worried about losing a new client on his first night.

"My boyfriend Cory will be frantic if I stay much longer." laughs sophie.

"Do you jump when he says too Sophie?" asked charles.

"No Charles, but it's easier this way I will be back tomorrow."

"Yes you must keep that Ass looking great Sophie."

"Look you will make me blush, got to get going worked up quite a big sweat earlier Charles." laughs sophie.

"Yes did notice Sophie, why don't you just shower here?"

"Next time Charles, just need to keep my Cory happy."

"Lucky Cory really lucky." charles says has sophie walked away shaking her butt.

Sophie went home showered and couldn't get Charles out of her head. Both of them eating dinner Sophie suggested that they should go to bed. Cory knew exactly what that was for Cory as the best sex he's had since his girlfriend moved in. After making multiple positions over ten minutes of sex they ended up laying down together. Still Sophie hasn't been satisfied but her Cory is completely satisfied and is blown away.

"Wow Sophie you need to go to that gym more often." exclaimed cory.

"Yeah I feel reinvigorated Cory working up a sweat in the gym, so you happy for me to go more often."

'Yeah definitely can go there every night." replied cory.

That was the start of Sophie's regular gym stops before heading home. Always loads of squatting light weights that kept all of her body toned. Especially Sophie's Arse it now seems bigger fuller definitely gets more firmer. This does not go unnoticed by her black gym instructor Charles. He's now really hoping to catch her alone. That night before he could get Sophie all alone by herself she left again. He did take ages as she squats looking at her big butt. He's hoping one day he will end up instructing Sophie one to one after class.

Sex between the both of Cory and Sophie as never been this good with Sophie now closing her eyes. Sophie's eyes closed up believing the black Gym instructor is the one that is fucking her. This becomes the normal Sophie spending each night at the gym then it's back home for her shower is then sex. This is about to change over the next week her boyfriend is going to spend a night inside a local hotel. He's going to watch a band his friends are going to stay the night inside the hotel that the band is playing at. This left his girlfriend Sophie all alone for the night, this would leave to her sexual awakening.

The night as come for Sophie to be alone and Cory to stay out with friends inside a hotel they would be watching their band. Sophie finished her shift cutting hair and texted Cory telling him to enjoy himself. Then off to the gym for her daily workout Sophie is obsessed in keeping her figure. She also liked the attention from Charles the way he made eye contact also makes her blush. Tonight's less busy than normal with only a few inside their gym. Charles waves over at Sophie which she likes he's then showing someone how to use gym equipment.

Sophie's looking her usual sexy self with her long hair tied inside a high ponytail. A tight bra sports top that pushes up her big large 36 D's a second skin pair of black leggings. They're really great at showing off her gym butt all of those squats have made it firm with large glutes. Charles as always makes sure he took a few seconds to appreciate that fat butt watching her as she squats. Within a few hours it was only Charles with Sophie and a regular married couple in the gym. Charles now as time to approach Sophie as he made some small talk.

"Hi Sophie you not skipping leg day, it's really working."

"Cheeky Charles, you know I don't miss my squats." laughs sophie.

"Yes I can see you don't miss any squats Sophie, you could crush pineapple's with that butt." laughed charles.

"Come on Charles your old enough to be my Dad."

"Do you fancy your Dad, his he fit like me."

"Wow Charles, you really don't half love yourself."

"No I see the way you look at me Sophie, if you and Cory break up you know where I am."

He then helps her with some weights and stood up over her as she lifted up the bar. Sophie got an birds eye view of Charles crotch and sees a definite bulge. It looked way bigger than her boyfriends it makes her pussy wet just imagining how huge it was. While they're both training together the married couple gets up and leaves the gym. Leaving Sophie alone with her black instructor Charles as Sophie does some more squats before surprising Charles.

"Hi Charles would it be okay if I showered here tonight?"

"Well my facilities are not beneath you are they anymore Sophie."

"They're never beneath me Charles just tonight I don't have to rush home."

"How come does your boyfriend trust you now." laugh's charles.

"No he's not home tonight Charles,I am all alone tonight."

"Really Sophie all night alone."

"Yes Charles, he's sleeping at a hotel after watching an band."

Sophie got up goes towards the changing rooms while Charles decided to lock his gym closing up early. Sophie grabbed an towel shampoo then she goes inside the shower. Her clothes come off and then all her underwear as she got into the shower. Soon there's soap covering over her firm teenage body in her eyes with the shower steaming up. Not aware of Charles who's stripped off making his way to the shower. His gym body is of a much younger man all toned and muscular not a man of thirty eight. Standing just over six foot tall with a impressive ten inch black cock that will be a shock to this teenage girl.

Sophie still unaware of someone entering her shower then suddenly a pair of strong hands touch her back. Then is large black hands reach around and cup on her large breasts the hands are black. Soaping the large breasts tweaking both long nipple's as Sophie gasps out. Then another huge gasping whilst she felt Charles huge black cock touching up against her Ass cheeks.

"No this is wrong someone will see us, no Charles this is wrong."

"It's okay the gym is locked up Sophie, it's not wrong we both want this."

Sophie reached back feeling Charles big cock cries out in big shock. Before Sophie started stroking it's length moaning out in total disbelief at it's huge size. It just kept growing with her stroking now her hand is not enough to stroke on this huge black cock.

"Has Cory got one this big Sophie?"

"No it's not half this big it's huge." sophie whispers.

"Keep on stroking it Sophie, when did you say your boyfriend was home."

"Not until tomorrow Charles."moans loudly sophie stroking soap over charles huge black cock.

Then Charles pinned Sophie up against the tiles inside the shower his black cock nudging up against her pussy. The outer lips parting for is huge ten inch black cock to slowly enter her.

"No Charles we can't, what about Cory."

"What about your Cory, he's out enjoying himself it's about time you also enjoyed yourself Sophie now relax."

"Ohhh Mmmmm." moans sophie as the big black cock enters her.

Charles now adding his huge cockhead pushing Sophie into the back wall. His big black hands lifting up each large breast upwards while her fat teenage Arse is up against his groin. Another push while he's nuzzled his lips against her neck. It's way to much for Sophie who groans out as her wet pussy opened for his huge bell end.

"God so big fuck Cory, fuck me Charles."

Charles squeezing her breasts pushed in further adding four inches of black cock.

Her big Arse resting against his groin as that huge cock keeps entering her. Cory's not in her thoughts anymore Sophie's only thought is black cock. Charles whispering in her ear gently kissing her neck his huge cock keeps on entering. Now over seven huge inches of black cock inside Sophie. Already deeper than Cory as ever been in her teenage pussy. Sophie is realizing it's also twice as thick than Cory's little white cock.

"God fuck me Daddy." whimpers sophie.

"Yes Daddy sounds good Sophie,yes push that fat Ass back on me."

"Don't you like this Ass Daddy?"

"Yes it's spectacular, just how those squats have made it Slut, big fat and firm."

Sophie's pussy squirts over Charles when he called her his Slut. His big cock nearly balls deeply it's stretching Sophie's pussy wide open. He's pinching on her nipple's while thrusting in and out of her teenage pussy.

"Gawd fuck your white Slut Daddy it's so fucking deep."

"Just a little more to go Slut."

"Fuck there's more on God Daddy." moans sophie squirting over his huge cock again.

Then another push and Sophie is pinned to the wall with Daddy pinching her huge nipple's his balls banging up against her Arse. The whole ten inches of huge black cock twice the size of her boyfriend Cory and twice as thick. The white teenager is always going to crave his big black cock.

"OH FUCK SO FUCKING BIG." moans out sophie.

Charles is now thrusting in and out of her pussy banging his black balls up against Sophie's tight firm Ass. The teenage white girl having the fucking her body deserves how could her Cory ever follow this up. It's reaching parts of Sophie's pussy that's as never touched before. Her pussy sprayed lady cum all over the tiled shower. Her big Arse pushing back to meet all of the hard power fucking off Charles. This black man Charles is older than her Dad but is fitter than her eighteen year old boyfriend.

"Yes Daddy Fuck me treat me like a Slut."

"Yes your Ass is all mine Slut, tell Daddy Slut."

"Yes Daddy, my big Ass my fat gym butt it belongs to you Daddy."

Sophie cums again covering Daddy in big squirt of her lady cum. This big black cock teaching her teenage pussy all new skills like how to squirt. Sophie never squirted with Cory's cock inside but he's less than half this big black cock inside her. Charles now thrusting in and out his cock getting the white teenagers pussy to sing. In and out his cock fucking away all the sounds are cursing moaning and water splashing off her big butt.

Daddy's big hands move from her nipple's and grab her hips while she bends at the waist and holding her ankles. Showing off her gym skills and flexibility while Daddy's looking down at that huge Ass she's been working out. It won't be long until her wet pussy gets bred Sophie's not been taken any birth control. Cory would always use a rubber when they had sex but they don't do them in Charles's size. Sophie had not thought about the risk of getting pregnant all that mattered is that cock. Sophie then snapped out of her sexual frenzy with the realisation she could get pregnant.

"You won't cum in me will you Charles?"

"No promises Sophie, I will pull out, don't go pushing that Ass back like that." moans out charles.

"Don't cum in me please, Daddy my Cory wears a rubber."

Too late her firm big Ass bounced against his groin Charlie's balls tightened. Charles shooting streams of cum deep in Sophie's unprotected womb. Sophie panics whilst her teenage pussy and womb fills up with cum. Stream after stream of his thick baby batter filling up her teenage womb.

"No Daddy you promised me you wouldn't cum inside my pussy."

"Told you not to bounce your fat Ass back on me slut, it's too late now, it's a pity your Cory's not here, he clean all of my cum up Sophie."

"What is that going to do Daddy, you cum so deep inside me Daddy, anyway I don't want my Cory to find out, please don't tell him."

"It's okay Sophie it's our secret, lets clean ourselves up, continue this back at yours."

"At mine you serious?"

"Yes Sophie your Cory is not home is he?"

"No he's staying in a hotel with friends."

"Good lets get more acquainted Sophie."

They both dried each other while Sophie's amazed Charles's cock still remained rock hard. It throbbed all inside her little hands whilst she spends an age drying it. Sophie squeezed back into her underwear and all her gym clothes as Charles gets changed. Both of them walking the small distance towards Sophie's flat the minute they walk inside she started to get cold feet.

"No Charles this is wrong the flat reminds me all of Cory I love him."

"Sophie you enjoyed it earlier, what says that your Cory is not with some girl now."

"No he wouldn't do that to me, Cory loves me so much."

'Well you might love Cory, but we've both fucked, it's okay Sophie we will be really discreet."

Then Charles started stripping off all of his clothing. The top comes off it's reminding Sophie of his great physique then he drop down his pants. Sophie gasped out loudly when she again saw his big bulge inside his boxers. Then Charles quickly dropped his boxers to the floor made sure Sophie's eyes are focused on her huge prize.

"Sophie come here stroke it again."

"Yes Daddy." whispers sophie.

Sophie started stroking on Daddy's huge black cock two little white hands barely covering all of his cock.

"My Gawd Daddy it looks bigger, you cum earlier, my Cory could never get hard like this again in the same night."

"Look Sophie little whitebois will never be my equal, or too other black cocks."

"Ooh Daddy it makes me all wet when you calling my Cory a little whiteboi."

"Yeah he's half my size, Sophie now spit all over Daddy's black cock, yes good add more see how it glistening, now keep on stroking it Slut."

"Ooh Daddy you shouldn't call me a Slut, it makes my pussy all gush, what are you going to do after cuming inside me."

"Look it will be fine Sophie stop worrying. now if only Cory was here he would clean you up."

"Daddy you said that earlier, why would Cory clean up your cum?"

"Look Sophie it's the natural world order. a small cock will bow down to a huge Alpha cock."

"Daddy this certainly is a Alpha cock it's big no it's huge, especially compared to my Cory. my one hand easily stroked his cock, while both my hands look lost on your cock."

"Sophie take Daddy to your bedroom."

"It's wrong on Cory, I don't like cheating on him, I feel so guilty."

"Yeah guilty enough to be stroking my big cock Sophie, look Cory would want you to be happy wouldn't he?"

"Yeah I suppose so Daddy."

"Good now your happy stroking my cock, now where's your bedroom."

Sophie led the nude black gym instructor into the back bedroom by his huge cock. Stroking it's length with every step to the bedroom gasping as it kept growing. They arrived Daddy lays on the bed cock strokes slowly inside his hand looking at Sophie's hot teenage body.

"Sophie show Daddy that great gym body again?"

"Yes Daddy you want me to strip for you?"

"Yes nice and slowly Sophie, yes look at your Daddy's cock while you strip."

Sophie slowly removed her sport bra top both large breasts were revealed. Her big breasts 36 D with nipples you could hang your coat on, then kicks off her trainers. It was then her skin tight leggings were now slowly removed grabbing the waistband.

"Yes Slut look up at Daddy, my little girl someone is very excited, look at the mess of your panties Sophie."

Sophie's blue eyes glazed over while her soaking panties slid to the floor. Her pussy wet and puffy swollen after it's earlier hard deep fucking. Her teenage thighs opened instinctively wider for Daddy a little drip of pussy juice lands on her panties. Daddy's stroking his cock in her view all thoughts of her Cory disappeared. Daddy wants to view that fat gym Ass again soon it will be his and his alone.

"Spin all around Sophie show your Daddy that gym Ass."

Sophie spun around slowly whilst slightly bending to show off her big Ass. It's what Daddy as been lusting after for months it's perfect, her Cory is a lucky man. Her Arse parts revealing both holes to Daddy soon he will take her tightest of holes.

"Now Sophie come to Daddy stroke his cock again."

"Yesss Daddy." sophie replied with a deep wanton lust in her voice.

Sitting next to the older larger black man immediately stroking his huge black cock. Daddy pinching each of her erect nipples before plunging his tongue deeply inside her teenage mouth. Sophie is soon doing the same plunging her tongue deeply into Daddy's mouth both have only one desire. Desire to please each other while Daddy's desire is to dominate this teenage white girl. They kissed moaned and Sophia kept stroking for a few minutes until her Daddy decided he wanted more. Breaking their kiss Daddy needed more hot wet teenage pussy he sucks on a nipple first before he talks to Sophie.
