You don’t know what came over you when you agreed to join your friends Amy and Lily for a free tryout with a personal trainer. There was a moment before you all got ready to leave where you considered dropping out, but it would’ve be almost impossible to considering that your friends had been pestering you about doing it for weeks. And also, you didn’t have to pay for this one time session so what’s the harm?
At the moment, you were all waiting for your PT to show up so Amy suggested to warm up on the treadmill for a few minutes. The two of them were busy checking their reflections and taking selfies but you weren’t interested being a part of that. Amy and Lily were the type to use the gym as an opportunity to attract their gym crush of the day. You didn’t blame them though, they were gorgeous (you are too ofc) but it did mean that they kind of use you as leverage to flirt with guys.
Since you were a lot more shy and insecure compared to them, it was easy for them take advantage so you were guessing that they brought you along to feel better about themselves.
“Hey ladies, are you here for a private session?”
The 3 of you turned around and saw quite literally a wet dream in a human form. He wore a white tank top that showed off defined muscles and his black joggers made you all wonder how much he was packing underneath. His gorgeous smile supported with his dimple made you thank the heavens that you decided to join your friends.
“I’m Sunghoon and I’ll be your PT for today”
The three of you gave your names and he shook your hands. However you couldn’t help but notice that when he got to you, he held your hand for a bit longer and sent you a wink. Oh this session is going to be fun.
As you all followed him to the private gym on the second floor, your friends couldn’t help themselves and whispered about how hot he was and what they wanted to do with him. You never would’ve admitted it out loud but you most definitely agreed with what they had to say.
You entered the room and Sunghoon went to the corner to set up the speakers and blasted some upbeat music
“So Sunghoon, are you single?” Lily asked
Sunghoon just smiled and replied “Yes”
And obviously Amy had to pry further “Are you seeing anyone or looking for a partner?”
“No I’m not seeing or looking for anyone. Ok so let’s start with a few stretches” you were so glad he diverted the conversation. You’d rather the ground swallow you whole than listen to you friends’ unbearable flirting.
The 3 of you followed his directions behind him and reached down towards the floor. And when you thought it wasn’t over, your friends started again
“Hey Sunghoon. Could you help me stretch a bit more? I need a bit of a push” the two of them snickered and Lily added
“Me too. I love a good stretch and need you to stretch me more”
You thought to yourself “Omg have I just landed myself in some cringey storyline at the start of a porno???”
Sunghoon, being the professional that he was, turned around and just slightly pushed down on their backs before returning to his previous position in front of you.
Lily then looked in your direction. You weren’t the most flexible person so it was a bit difficult for you to keep your hands planted on the floor
“What is that Y/N? You’re not very flexible are you? You should stretch more” she laughed
If that wasn’t embarrassing enough, Amy had to add on “Sunghoon you should’ve seen her when we tried yoga. It was like watching a grandma haha. Lily and I go often though, we can show you after if you’d like”
Well didn’t you just feel on top of the world right now. You felt like a tomato and it was not because of the stretching
“Please refrain from talking about anything outside of this session. I am just doing my job as your trainer and I would appreciate if we could keep things professional thank you.” You could sense from his response that you weren’t the only one getting annoyed by your friends thank god.
“Ok so we’re going to reach down again but push further and hold it there. To make things easier, close your eyes and it will help you level your breathing”
Both Amy and Lily bent down to stretch but you took a moment to shake off your legs when you saw Sunghoon turn around and walk towards you. He came behind and placed his hands on your waist.
“Let me help you stretch a bit further pretty” he whispered in your ear and lightly rubbed your waist.
You felt the hairs on your neck prick up from his breath fanning again your neck. He then pushed your shoulders down and dragged them down your spine the further down you bent. As he pushed down on your lower back, you felt him slightly grind onto your heat.
It seemed like the other two didn’t notice anything since they weren’t making any noise. You never felt so alert but you could help it when you pushed back onto his crotch. The two of you carried on slightly grinding on each other for the entire stretch until till he brought his hand back to you waist and left to go back to his mat.
“Now we’re all stretched and can get onto the workout”
Damn it already felt like you had a whole work out with how heavy you were breathing. Obviously, Amy had to point out
“Damn Y/N how are you already out of breath. I don’t know how you’re gonna survive whatever Sunghoon’s gonna make you do”
You didn’t say anything back but you saw in the mirror in front a slight smirk on Sunghoon’s face. Oh if only you knew Amy
Throughout the whole session, it seemed like Sunghoon couldn’t keep his hands off you. If anyone was to walk in, they would’ve thought it was just the two of you working out together. Because he made the 3 of you do a circuit, the other two weren’t able to pay attention to Sunghoon feeling you up for each exercise. You didn’t know how much more you could take before you’d say fuck it (quite literally) and just jump his bones. Even if your friends were present.
To your relief, Sunghoon announced that the workout session was over and it was time to cool down. You thought that this would be your time to actually relax your muscles and focus on getting your heartbeat steady again. But instead it started to speed up again when Sunghoon spoke up again
“So the next stretch, you’re going to spread your legs apart and reach forward to put you hands and forehead on the floor”
He got up and added “I don’t want you to injure yourself so I’ll help you with this one”
Oh god
Once again your friend proceeded to stretch and Sunghoon made himself comfortable behind you again and mumbled so quietly that you could barely hear him
“Don’t make any noise princess”
He used his left arm to pull you back and hold you against his chest while his other hand dragged down your front and cupped your heat. You almost let out a gasp but quickly bit your lip to stop yourself. He carried on rubbing his middle finger up and down between your legs and when he dragged it to your clit, he brought his middle three fingers to put pressure onto it and rub circles before repeating the process again.
The view in the mirror in front of the both of you was so dirty yet so arousing. The thought that there was a chance that one of your friends could just look up and witness your act made you feel a bubble of excitement in your stomach
Sunghoon remembered that the two of you still had some company to he quickly ordered “Now keep your heads down and reach over to stretch on your left side”
It was getting more difficult for you to not moan out loud so you moved your head back to lean on his left shoulder and lightly panted into his ear. He turned towards you and leaned in for a kiss. It was so wet and sloppy and made you gush even more. If it wasn’t for the loud music playing, you were sure that your friends would’ve picked up on the lip smacking as you carried on swapping saliva. With a wet smack he pulled away from you lips.
“Ok remember to keep your heads down and now stretch on your right side”
When he went back in, the both of you stuck your tongues out and he started sucking you tongue in and out of his mouth. You needed to feel more so you bent your knees and planted your feet on the ground to start grinding into him palm even more as you both wiggled your tongues together. You felt the heat build up in your stomach and whispered to him
“I think I’m gonna cum”
He pressed your foreheads together and said with a smirk “Not yet baby”
You nearly let out a whine and he reluctantly removed himself from you
“Now slowly lift yourselves back up and slowly stand up”
Although you weren’t the one who had been stretching, you got up with a slight wobble from the uncomfortable feeling of wetness in your panties along with your denied orgasm. The other two didn’t question anything since it had been a hard workout.
Sunghoon clapped his hands together “That’s it for the session! Thank you for your hard work” and bowed
You and your friends thanked him back and went to gather your belongings.
“Wait Y/N, I know you struggle a bit more with your flexibility. Would you be able to stay back for a bit so I can help you out? I would feel terrible if you didn’t feel properly stretched after a workout and you don’t want to pull anything” Sunghoon said to you with a smile. And who were you to turn down such an opportunity
“Oh ok! You guys don’t have to wait up for me if you want to go home and shower?” You really hoped they would leave and not question anything since it was quite sudden. Fortunately they agreed and left, leaving you alone with the hot trainer that hadn’t taking his eyes off your ass.
Once the doors closed he grabbed you by the waist to spin you around and immediately attacked your lips with his in a wet kiss. Both of you tongues fought till he stuck his tongue all the way out into your mouth. He licked all around the inside your mouth and slightly moved back to suck your tongue all the way into his. His hands snaked down to grab a handful of your ass and you finally let out a moan. He took the opportunity to slot his thigh between yours and moved you back an forth over his solid muscles. All of a sudden he stopped everything and panted out
“Ok baby, let’s stretch you. Be a good doll and lie on your back for me” he slapped your ass and went over to lock the doors
When he returned to you, he kneeled at your head and moved you so that your head was on his crotch and you could feel his hard dick “Such a good girl. You take orders well don’t you sweet thing”
You were breathing so hard with anticipation that your squeaked out a small “yes”
He then started to rub his arms down your body, starting from you shoulders, slowly rubbing small circles over your clothed breasts and moving them down to your thighs. He took his time rubbing the creases where your thighs met your crotch and smoothed over the outside of your pussy.
Your breathing was slightly shaky and he could see from the way your chest moved rapidly so he chuckled “Are you nervous baby? You don’t need to be nervous. Daddy will take great care of you. Just take deep breaths for me princess”
As you deeply inhaled, you felt his hands grab the sides of your thighs and pulled your legs up towards your chest. You carried on focusing on your breathing as he stretched your legs so that you were bent in half and he slightly leaned forward to place your feet on his broad shoulders
“God baby what a beautiful sight. Look how much you can stretch pretty. Maybe you were faking it when we were warming up huh?” He teased
When he looked in the mirror, all he could think of was how he could easily he could shove his hard dick down your throat. If he wasn’t already rock hard, he most definitely was now
He then let out a growl and slowly bent down towards your centre “Fuck babygirl, with the way you’re stretching, you make it so easy for me to just… eat… you… up”
Without any warning, you felt his hot tongue run from your clit and all the way down the seam of your leggings and he shook his head side to side, addicted to the smell of your arousal. You could feel him take a deep intake through his nose where your clit was and he carried on licking your clothed core. But he wanted more, so he lifted your hips back off the floor and pulled the back of your leggings and panties all the way past your ass. He was too needy to pull your leggings and underwear off your legs so he bunched them at your knees and used his upper arms to press the back of your thighs down till you were bent in half.
Your head had moved so it was on the mat and his hard dick was almost pressed against your face. You could feel his breath against your exposed pussy as he brought his fingers to spread your glistening lips.
“I’m telling you, this has got to be the prettiest pussy I’ve ever seen baby. You’re so creamy and look so tasty”
He took another whiff before saying “Ah daddy’s gonna drink up your juices so well princess”
And with that he dove in tongue first to lap up at your entrance. He tongue fucked your pussy and sucked at your clit harshly. God he thought at this moment that your pussy would be his new addiction and he need to taste it everyday for the rest of his life.
The music playing from the speakers did absolutely nothing to cover the pornographic sounds that came out of your mouth. Even with Sunghoon eating your pussy so deliciously while holding you down so you can’t escape, the sight of his dick on top of you was absolutely mouth watering. You brought your hand up to his hard cock and gave it a squeeze before moving you hand up and down.
Finally, Sunghoon detached himself from your pussy to let out the most delicious moan you’ve ever heard and started to grind into your hand. His moans alone would’ve probably made you cum right there.
“Oh yeah that’s right baby squeeze daddy’s cock. You wanna suck on it too? Lick it like a lollipop my gorgeous girl”
He reached down to his joggers and pulled them down just enough to release his dick. It sprung out and slapped your cheek before resting by your face.
“Suck daddy’s dick princess while daddy eats up your creamy pussy” he growled before eating you out again
You lifted your head off the ground to take his hard, warm dick into your mouth and sucked as hard as you could. The suction made him moan so loud that the vibrations felt more intense than any vibrator you had ever used. You almost wanted to scream from how good his tongue felt. You both carried on making each other feel the most pleasure either of you had ever felt. And the vibrations from your moans only intensified that pleasure.
You were so concentrated on making him feel good that it took you a moment to realise that Sunghoon started to bend your legs further back. Without any warning, his tongue flickered across your clit a few times before it ran all the way down to your asshole. It was the first time anyone had touched your other entrance and it felt so good.
“Oh fuck daddy please do that again. That feels so good” you moaned out and took his cock back into your hot mouth.
“You like it? Such a greedy baby. But daddy will give you whatever you want” he said smugly
He used your ass as leverage to pull you back and forth. His flattened tongue stroked up and down your crotch from your puffy clit to your winking rim.
“Oh shit baby I can’t get enough with your taste. This is the most delicious pussy and ass and it’s all MINE”
The slurping and moaning was so hot and the both of you could feel your orgasms building up. Sunghoon started to rut into your throat and groaned into your pussy. He so desperately wanted to moan out load and let you know how well you were sucking him off, but he wanted you to come as well so he started to suck and vibrate his moan onto your clit.
If it wasn’t for him grinding on your face, you would’ve screamed from the overwhelming pleasure. You needed to cum right now or you’d explode. So you brought your hands to the back of his head and pressed him further into your pussy. He loved the feeling of you using his face to get off that he started to thrust in your face even more. At this point you didn’t care if it was desperate, you just needed to cum, so as you pressed his face in your centre, you started humping vigorously into his mouth. The both of you were getting closer and closer. You wouldn’t stop humping each other’s faces and it was so hot.
All of a sudden, Sunghoon’s thighs started shaking and you sucked so hard as his cum spurted into your throat. It turned you on so much how YOU make his legs shake and how YOU got him to release the most beautiful moans.
He carried on twitching but he still needed to make you cum. He was craving for it. So he returned his mouth back onto your clit and created a vacuum whilst moaning from his own pleasure
“Yes. Yes. Cream in my mouth princess. Daddy wants to squirt all over his face. Drown me in your juices omg. Use daddy’s face. Hump me baby hump me”
So you carried on grinding on his face and quickened your hips when you felt an overwhelming amount of pleasure wash over you.
You screamed so loud as you squirted hard into Sunghoon’s mouth. He was completely obsessed with your taste and drank up everything you had to offer. He held your shaking leg back from closing as he slurped at your entrance.
You laughed and tried to push him away from your overstimulated pussy
“Sunghoon I’m sensitive”
“Uh uh let me drink you up baby. I’m not done cleaning you” you felt him smiling against you
At last, he slowly lowered you legs and moved so he could hover over you and kiss you.
“You did so well baby. Can you taste yourself?” he mumbled against your lips and stroked your hair
The way he looked down at you made your heart skip. This all felt so… natural
“I know this is all fast and probably a weird time, but I’d really like to get to know you. Would you like to go out for dinner with me some time soon? Of course you don’t have to say yes, I completely understand” he started to ramble with a slight tint in his cheeks
How could one be so cute after giving you the best head?
You shut his rambling up with a peck and responded “I would love to get dinner with you Sunghoon”
His precious smile just made you want to squeeze his cheeks! He gave you more pecks and leaned down to suck on your neck
“I’m still so hard baby” he groaned
“Oh yea? You wanna fuck my pussy baby?” You teased back at him
He moaned and begged “Yes please doll. Let me fuck you so hard”
“Ok then Hoonie”
After hearing that nickname and your approval, he quickly stripped you from your clothes and ripped his off himself. His well-sculpted body was everything you had fantasised about in your wet dreams. And the fact that is was paired with the gorgeous face of a perfect man written by females themselves, was just icing on the cake.
He spread your legs and spat onto your pussy (not like you needed it) before easing his way into your heat. His girth stretched you so deliciously that you felt like drooling. It was the most perfect dick ever. And it felt perfect inside you as well.
He rutted into you and stared into your eyes, leaving his mouth hanging open. The sweet melody of your moans together and skip clapping was something that people would pay to get off to. The mirrors were fogging up from the panting and intensity.
“Baby please ride me” Sunghoon panted. He did want to carry of fucking you at his own pace but he was so close to cumming and he really wanted to watch your bare tits bounce in front of him when he came.
You both flipped over and you quickly started to grind on his dick. Now that he had helped you to stretch, your hips were rapid and you angled your clit to drag along his pubic hair. It feels so good omg
Sunghoon looked down at your pussy and the way your juices coated his pubes and pelvis, he moaned out so loud
“You’re so hot oh my fucking god princess. Yes! Ride my dick like that. Can I cum inside you baby?” as he held you up and thrusted up into you, angling his hips to hit your g spot
“Oh fuck yes daddy cum in me! You’re gonna make my cum again”
“Cum with me baby. That’s it”
And just like that, you both came hard. He filled you up so full that it started to leak out of your pussy
You were both shaking so hard that you collapsed and layed on top of him.
You were both trying to catch your breath as you snuggled up together. You could feel him press sweet kisses to your hairline and he dragged his fingertips up and down your spine.
“You good princess?”
“Yea” you respond with a happy sigh and lift yourself up to sit on him
He looked up at you with such fond eyes and stroked you waist. There was a fainted mischievous smile as he brought his fingers down to where your were both connected to gather his cum that spilled out
“It’s taking all of the strength in me to not make you sit on my face and have you drip in my mouth” he groaned whilst staring at your soaking pussy. “If you’re free after this, maybe we should continue this at mine and we can find out how many times I can make you cum?”
You slowly lifted yourself off his semi hard member and situated yourself on his lower stomach. You still wanted tease him a bit more so you started to grind on his abs. Sunghoon moaned at the warm feeling and layed his head back down to try and control himself.
“I guess I’m free to do that. But only if you let me cum on your abs and suck you off in the shower” you flirted back
He bit his lip with a smile “Deal”
Oh weren’t you glad that your friends dragged you for a workout
