Se Ah grabbed Min Hyun by the hair and pulled his head back, making sure to retain eye contact. His dark, almost misty eyes were looking at her with a mixture of excitement and intrigue - the look of a person that was both scared and turned on.
"Min Hyun, you'll have to be absolutely quiet here, understood? If you make yourself heard, I won't let you finish."
He nodded and smiled - he was up for a challenge.
The woman pulled up his shirt, stuffed it into his mouth, and made him bite it.
"Here, if you drop your shirt down, I won't be happy."
His silent obedience flared up Miss Yoon's excitement; she placed her hands on the guy's chest and started kissing his neck. His body reacted with a tiny shiver, and as Se Ah's lips began to slowly move down, his heart began to race, desperately trying to get out of the restricting cage of his ribs. All of a sudden, she placed her right foot on Min Hyun's crotch and pressed it hard as if she was trying to kill a bug, and a muffled grumble escaped his stuffed mouth.
"Tsk. Look how hard you got, you dirty pervert. Have you always dreamed of getting fucked in a dirty stall of a coffee shop bathroom?"
The intern tried to smile while still holding his shirt in his mouth. He did not mind getting fucked behind the dumpster if the person fucking him was Yoon Se Ah.
"Pushy subs are a rare occurrence and to be honest, I've never had one before, but it's not half bad. I'll train you well and turn you into an obedient dog, Lee Min Hyun."
The woman started rubbing his bulging privates with her foot, carefully observing the guy's reactions, and the moment he closed his eyes in an attempt to enjoy what was happening more, Se Ah grabbed his face by the chin and leaned forward.
"Did I tell you to close your eyes? Keep them open at all times. Or... Do you want me to help keep them open?"
She unbuttoned her shirt and pulled down her bra, exposing her shapely breasts. Min Hyun swallowed hard, and his face turned red; he looked up at Miss Yoon's face as if asking for her permission but before she could answer, he lifted his hand and slid his right index finger across her nipple. Se Ah slapped his hand with an unexpected urgency and shook her head with a disappointed expression.
"Today, too, you are only allowed to look."
Although it was intolerable, the guy took a deep breath to help him hold himself back, pulled his hands behind his back, and tightly grabbed his own wrists. Miss Yoon started unzipping his pants, then pulled them down along with Min Hyun's underwear, took off her right shoe, and returned to rubbing his throbbing dick with her bare foot, making sure to apply enough pressure to inflict just the right amount of pain.
"I've already noticed it back then but you do have a pretty and big cock. I bet you're dying to plunge it inside me."
She pressed it harder which made the guy flinch and start trembling like a wet dog.
"Look at you, you're leaking like crazy, my foot is all wet now. Don't you think you should do something about it?"
Min Hyun looked at her with glistening eyes, then opened his mouth wide, dropping his already-soaked shirt on his chest, and said,
"Here. Let me clean it for you, Miss Yoon."
Se Ah grinned and leaned on the door. The position was not exactly perfect but the thrill of the situation made her feel relaxed, overcoming that uncomfortable feeling. She raised her right foot and shoved it tight into Min Hyun's mouth.
"Go on, clean it, Lee Min Hyun."
The guy started moving his hot slippery tongue in between her toes, licking and sucking on them as if they were sweet candies. To Se Ah's great surprise, he kept supporting her foot with his hand all the time as if making sure that she would not feel tired and pull it away too soon. She did not hate it. Finally, when she felt like that was enough, she pulled her foot away and smiled.
"You sure know how to use that dirty tongue of yours."
Min Hyun put on an unexpectedly happy smile and whispered, barely holding himself back,
"Thank you, Miss Yoon."
Se Ah smirked, picked up her bag, rustled her hand through its contents, then pulled her hand out, and looked down.
"I do not normally carry anything like this around but I had a feeling you would provoke me first so I put it there just in case. It's time to bring your experience up to level one."
Min Hyun did not have a chance to look at the thing in Se Ah's hands - she opened his lips with the fingers of her left hand and shoved it inside his mouth, forcing him to close his lips again. He felt something soft and synthetic, almost like rubber, and he soon realized what was about to happen. Miss Yoon pulled the thing out, briefly examined it, and looked at the guy's slightly bewildered face.
"I'm sure your saliva will serve as a good enough lube."
She then tapped her hand on his left inner thigh and said,
"Spread your legs wide and move your pelvis forward."
He did exactly as he was told and before he knew it, he felt a sudden painful push and a feeling of tight pressure inside his hole.
"M-miss Yoon?"
"This little thing is a prostate massager that has both inner and outer stimulating functions. Don't worry, this is a beginner level so if you relax, you will start feeling good pretty soon."
Although Min Hyun was prepared to experience anything, he still did not expect Miss Yoon to use her toys outside her apartment. While he had to admit that her boldness turned him on even more, the fact that she was already able to see right through him made him feel a little bit upset. He was about to follow Se Ah's recommendation to relax when all of a sudden, she grabbed him by the collar of the shirt and pulled him up.
"Get up, Lee Min Hyun, I want to show you something."
The guy did not know how to react at first but her intense gaze and sly expression were almost hypnotic. Although with an effort, he got up from the toilet seat and felt a weird but somewhat pleasant pang inside his ass - the massager began to work on him.
Se Ah opened the stall's door, dragged Min Hyun out, then stood behind him in front of the large bathroom mirror, grabbed his dick with her right hand, and smiled.
"Now look at you, Lee Min Hyun. Do you like the view?"
The intern looked at the woman with a confused expression and almost shouted,
"Miss Yoon! What if someone walks in?!"
"So now you're scared of getting caught? Your advances in the elevator were pretty bold, I thought you were not afraid of anything. Oh well, if someone walks in, then they will see both your pretty cock and your nice, hard ass."
Min Hyun gulped and look at his reflection. He was not really afraid of someone seeing him in that condition but he sure did not want Miss Yoon to get caught with him looking like that. But the moment Se Ah started moving her soft hand up and down his penis, his mind became cloudy with pleasure and sweet fatigue. Combined with an unfamiliar feeling induced by the anal plug, his whole body began to melt and it was already hard to stand straight. He leaned forward and grabbed the sink with both hands, letting out a loud moan.
"Does the idea of having sex in the public bathroom turn you on? You pervert, your dick is leaking, your whole body is trembling, you're about to explode."
She whispered those words into his ear, and the warm, ticklish sensation almost made him lose his mind again. He kept panting and moaning, his attempts to suppress climax made him sweat. Se Ah grabbed him by the hair and pressed his flushed face onto the mirror, making sure he can see it well.
"Take a good look at yourself, Lee Min Hyun. Look how filthy you are. You are a disgusting freak who likes being fucked in public places."
Min Hyun felt a strong sense of heat concentrating in his crotch and as he was about to gasp for air, he felt his body tremble as if he was having a fit which resulted in a sweet feeling of ecstasy and release.
While he was still trying to catch his breath, Se Ah wiped her hand, sullied with his cum, across his mouth, rapidly pulled out the toy from his throbbing hole, pulled him back inside the bathroom stall, and scoffed.
"Make sure you look presentable when you leave this bathroom, we still have some work left to do."
She washed her hands, put on her missing shoe, buttoned up her shirt, grabbed her bag, and left, leaving Min Hyun alone and completely messed up. Once her footsteps finally disappeared behind the door, he covered his face with his big hands and started laughing.
"God, Miss Yoon... You're unbelievable."
