Se Ah walked back into the room with her right hand behind her back. Seeing Min Hyun's naked, well-defined body on his knees, with his arms tied with thick, crimson-red rope was both sexy and somewhat cute, but his calm, although completely flushed face, was getting on her nerves too much, she simply had to change it. She put on a kind smile, placed the item in her right hand on the floor in front of him, and watched his hazy eyes widen from both anxiety and surprise.
"Miss Yoon? W-what is this?"
"What do you think this is?"
Se Ah touched the black ribbed dildo she had just stuck onto the floor with the toes of her right foot, then moved the foot to the guy's thigh, and caressed it a few times before she grabbed the rope tied around his chest and pulled it toward her, forcing him to follow that movement using his knees. When he was finally standing over the toy, the woman grinned again and pressed his shoulders, making him sit down at once.
Sharp, tearing-like pain shook Min Hyun's body immediately, after all, Miss Yoon did not even try to prepare him or use a lubricant, there was no doubt that this time she wanted to see him shiver in real pain, and he was willing to play along. He let out a pained groan and frowned his face, the intensity of the unpleasant feeling seemed to grow with every tiny move so he took a deep breath, moved slightly up, and pleaded,
"Miss Yoon, can we not do this? It's too big, I can't move."
"Oh... Is that so?"
For the first time ever since they started their relationship, Se Ah's face was dark and somewhat irritated at the same time. She looked scary that way, like a real master who was dissatisfied with their plaything and Min Hyun was afraid that if he does not play his role properly this time, she might end up being disappointed and abandon him completely, however, before he could say or do anything, the woman put her foot onto his stomach and pressed him down again.
"How pathetic, it was not even all the way in yet. Come on, work with me here, it will only feel good if you take it all in like a good boy."
She stroked Min Hyun's messy hair as if she was patting a dog, then wrapped her arms around his neck, and sat on top of his thighs which finally pushed him all the way down to the floor. The feeling of Miss Yoon's soft bare skin on his body, her hot wet privates touching his penis, and the scent that was emanating from her lose hair like some poisonous fume were so stimulating and arousing that he even managed to forget about the unpleasant object ripping his anus apart.
"Miss Yoon... your body weight is..."
"What? Are you saying I'm too heavy?"
"N-no!"
Min Hyun tried to shake his head in denial but Se Ah's tight grip on his hair prevented him from doing so. Moreover, none of his actions or words seemed to affect her facial expression in any way so he only closed his eyes, put on an apologetic smile, and pressed his face onto her naked chest, absorbing the warmth of her shapely bosom.
Still silent, Miss Yoon started slowly rubbing his penis between her legs, teasing, almost inserting it in but then sliding past it, leaving it out, throbbing and pulsating, and every time that happened, Min Hyun could not help but let out a disappointed, almost desperate moan, digging his teeth into the pale skin of her chest.
"Does it feel good now that I'm helping you?"
"...Yes."
His hot breath spread over her skin. She pulled his red face away from her chest and finally smiled again.
"But if you want to feel better, you need to put some work into it."
Se Ah fixed her position on top of him and let Min Hyun's pulsating dick slide all the way inside her. The guy let out a loud, relieved sigh and tried to push his face back to her chest but the woman did not intend to let it happen, instead, she pulled his hair down even harder, looked into his dazed eyes, and whispered,
"You need to move now, Min Hyun, otherwise I won't let you cum today."
The intern swallowed an invisible rock stuck in his throat, took a deep breath, and tried to move both of their bodies up by lifting his thighs. The mixture of sensations and the additional weight he had to hold made his legs shake at first but he quickly pulled himself together, and started developing a steady moving pace. It felt more like an exercise routine rather than lovemaking and even though he was rather athletic, after just a few moves, he was already sweating from both hard work and an intense feeling that was spreading all over his pelvis and lower abdomen.
Se Ah was still staring intensely at his face as if looking for any sign of weakness or desire to give up, and although Min Hyun was trying hard to maintain eye contact, from time to time he could not help but close his eyes or bite his lower lip in an effort to suppress his feelings. At some point, he finally gave in, let out a hoarse moan, and started panting with his mouth like a dog.
"Tired already? That's a shame, I can feel your dick pulsating inside me like it's about to explode. Are you really willing to give up now?"
The guy clenched his teeth and started moving faster as if to prove Se Ah wrong. The tension in his anus finally loosened up and an intense wave of pleasure that was previously only concentrated in his privates began to spread around, stimulating him even more and adding up to his vigor and speed. When the fire of ecstasy was at its peak, he tried to break through his loud panting, and whispered,
"M-miss Yoon... I'm... about... ugh!"
Not letting him finish that sentence, Se Ah lifted her body at once, and watched as the white, hot, sticky liquid squirted from inside Min Hyun's penis, sullying both his stomach and her thighs. The woman grabbed the thick red rope tied around his chest, pulled it to the side letting the guy off the dildo, and threw him on the floor, allowing him to catch his breath. When he finally felt like he could speak again, Min Hyun looked up at Miss Yoon, and asked like a child waiting to be praised,
"How did I do, Miss Yoon?"
The woman crouched in front of his body, gently stroked his cheek with her warm, soft hand, and smiled.
"You did well."
