Assistant's Training
In the quiet of late night, the sounds of squelching and a woman's moans drifted from the department office. The hallway outside was empty, but the only light came from the single lit office at the end of the corridor. Inside sat Su-hui, perched on the desk, legs spread wide.
Her crisp white blouse hung in disarray. The neat H-line skirt had ridden up, bunched around her waist. Her smooth, toned thighs parted toward the teaching assistant, trembling slightly with every gentle stroke of his fingers.
"Su-hui... you've become so lewd lately, haven't you?"
The squelching grew louder as his middle and ring fingers slid deeper into her dripping sex. He moved them in a slow, rhythmic rhythm, filling the empty office with the obscene sounds of her arousal. What had once been a bustling department filled with students and assignments was now soaked in nothing but Su-hui's wet squelches and her breathless whimpers.
"Ha-eut... ng... ahh..."
"Hng... something... more lewd than before... more like a real woman, isn't it?"
The wet squelch of his fingers made a sticky, squelching sound as her juices coated his skin and dripped from the desk onto the floor. Su-hui was reacting differently now. It wasn't just her face or body; the overall atmosphere felt ripe, more developed than when he had first taken her. Even then he'd known she was a filthy woman, but right now, legs spread and fingers buried in her, the scent of her arousal was heady.
As his teasing continued, Su-hui's body grew more sensitive. She arched her back and let out a soaring moan, her long, wavy hair swaying near the desk. Her waist curved backward, revealing red lace beneath her disheveled blouse. A couple of buttons had come undone, so her full breasts glistened with heat. The H-line skirt, once proper, was now crumpled and messy. Her smooth legs formed an M-shape on the desk, thin muscles flexing with every thrust of his fingers. Her panties hung caught at her slender right ankle. The way they clung there felt even more teasing than if they'd been tossed aside. And the black high heels that matched the skirt only made the entire exhibitionist sight sexier.
"Ahh... ah-eut... ng... thank you for touching me... it's not like that... ha-eut, please..."
"No... it was already like that before I touched you."
The teaching assistant smiled and pressed his fingers harder against her clit. Su-hui's breathing quickened and her hips bucked upward.
"Ha-eut... e-eut... ng... there... it's too good... ha-eut."
"With this kind of lewdness... you've taken many cock before, haven't you?"
"Nng... nng... nng... nng... a little... yeah... ha-eut... did..."
He chuckled lazily at her answer, as if to say "of course," and kept working his fingers without pause.
"Chirp chirp chirp chirp chirp..."
"Hah... aahh... nng... too much... it's going to cum... Master..."
"So Su-hui... how many cocks have you taken now?"
"Ha-eut... nng... a lot... five..."
"Five? You really aren't kidding!"
He was genuinely surprised. Even if she was lewd, he had expected two at most, maybe three. Five... incredible.
Damn...
His entire body burned with excitement. Five. He had slept with many women, but five was impressive. The slutty student assistant who had already racked up that many by the start of the semester... he pulled his fingers out and stroked her sex gently while asking, "Tell me about the sex you had."
"Aah... Master... please put your fingers in..."
"If you tell me everything, I'll get even hornier and it might feel really good."
He slipped just one finger inside and teased her inner walls slowly.
"Aah... still... ng... embarrassing..."
"What's wrong with it, Su-hui? It's fine... I'll make you feel good."
He lightly flicked her clit with his other hand and undid the buttons of her blouse. Her lacy bra came away, revealing her full, bouncy breasts.
"Just... ha-eut... outdoors... once..."
"Oh? Outdoors?"
"Haaah... yes... ng..."
Outdoors sex... and the way her pussy tightened so hard when she admitted it sounded like she had truly loved public exposure.
He added a second finger.
"Hng..."
"Chirp chirp..."
Slow movements, low voice: "One for outdoor sex... the next?"
Su-hui was so close to orgasm from the stimulation that it felt like she might break. But he skillfully stopped whenever she seemed about to cum, then started again, waiting for her answer.
"Haaaa... exercise... pilates... teacher... haaah."
"What? A woman??"
"Aah... no... a man..."
She thought it was lesbian, but it was a male trainer.
"Where? While exercising?"
"Haaah... yes... while... he took me... ha-eut."
"And the third?"
"Nng... just friends of the same age... my first time... he took my virginity... nng."
"Did you initiate?"
"Yes..."
"So you took him?"
The teaching assistant's cock hardened instantly. From the stories, these weren't simple fucks; the variations were endless. Outdoor exposure, fucking while wearing leggings, and even being the one fucking... he was grateful for her filthiness.
"Chirp chirp chirp chirp..."
He rubbed her G-spot faster, matching his growing excitement.
"And the fourth?"
"The fourth... nng... haaah... ah... can't... aah..."
"Why? It's fine, Su-hui. The teacher understands everything... you're still so beautiful."
"Haaah... the fourth and fifth... nng... 2 on 1... aah."
"Ziiik ziiik..."
Su-hui couldn't finish her sentence. The memory of the threesome and the stimulation had pushed her over the edge. Her juices squirted, soaking his hand and the desk.
"Haha... why do you always ask that? It's embarrassing..."
"Wow... threesome, Su-hui? You're really a slutty whore... but you look so pretty."
Su-hui remembered how his words had made her even more aroused.
"Hah... but when Master says things like that, or when I hear curse words, I get even wetter... please be rougher..."
"Hah... haha... haha hahaha... Su-hui, you're such a filthy girl."
Her juices were still dripping from the desk as she trembled. The teaching assistant's praise made her climax again, squirting harder.
Su-hui reached down and spread herself wider.
"Lewd... Su-hui's slutty pussy... please fuck it..."
"Hah... fuck..."
He pulled out his throbbing cock and slammed it into her soaked sex. Even though it was already dripping, her tight pussy felt like thick, warm mud, gripping him tightly.
"Hah... this grip... perfect..."
"Hng... Master... it's too good..."
"Puk puk puk puk puk..."
"Chirp chirp chirp..."
"Squeak squeak..."
As he thrust, the desk rattled and creaked. He freed her bra and let her heavy breasts bounce free. Su-hui moaned loudly, "Haaah... angh... angh... angh... so good... aah."
"The lewd feelings you felt... when did it start?"
"A-eut... e-eut... e-eut... I... don't know... just... haaah... from the beginning... haaah."
"Then maybe later I can try even lewder and more fun things with you?"
"Aah... angh... nng... nng... nng... nng... yes... I'd love that... aah... please... play with my breasts too... a-eut."
Her nipples stood hard from the sudden exposure. The teaching assistant licked one, swirling his tongue around the sensitive bud. Su-hui's whole body lit up with electricity. They moved their hips together to take him deeper.
"Su-hui's nipples... so sensitive, huh?"
"Ah... yes... nng... too... good..."
He remembered what he had said earlier. This slutty woman was worth training. He planned to focus on her submissive side first, though he hadn't told her the full plan yet.
"Chirp chirp chirp..."
"Aaaah... a-eut... aaaaah... it's too good."
Her juices gushed like a broken dam, making wet, slapping sounds with every thrust.
"A-eut... Su-hui... you're going to cum. Should I fill you inside?"
"A-eut... he-eut... inside... ah... please..."
He leaned over her, slamming deep. Su-hui lifted her head and sucked his nipple, her tongue teasing his cock to push him over the edge.
"Gluck gluck gluck..."
Feeling her tongue on his nipple, he came hard, flooding her pussy with thick ropes of cum.
"Hah... fuck... Su-hui's pussy is perfect..."
"Hah... hah... hah... hah... Master..."
"Su-hui, will you come again tomorrow? There's something I want to try with you."
"Hah... hah... tomorrow...?"
"Yes... the thing I mentioned... lewd and fun... you'll never regret it."
Tomorrow was Saturday. No classes. Only club activities or professors doing research would be around. He kept talking.
"Tomorrow... when you come... hmm... let's see... do you have a trench coat, Su-hui?"
"Hah... hah... yes I do..."
"Then... don't wear underwear... just that and come, with the high heels or something with a heel."
"...What? Naked?"
"Yes."
"Th-that's... too... embarrassing..."
Naked trench coat... the thought made Su-hui blush, but the teaching assistant began to persuade her gently. She had hidden some of her submissive tendencies. When those were fully exposed, how lewd and slutty she would become... he was eager to see.
Su-hui hesitated, but the more he talked, the more curious she became. The thrill of shame and perversion, the excitement from his dirty words... she finally agreed after a moment of thought.
"...Alright... actually... I'm a little curious too..."
"Good... Su-hui... I'll show you who you really are. But... you have to listen to me?"
"...Yes... Master..."
She reached for her panties to clean herself.
"Ah, Su-hui... why don't you just pull them up in the state they are and go home?"
"But... cum will drip..."
"It's late at night... and you have to listen to me, don't you? Listen carefully?"
"...Yes..."
She covered her dripping pussy with her panties. The warmth of his cum soaked through the thin fabric. With every step the sensation felt like it might leak out and expose her. The thought of someone seeing her cum-drenched legs made her sex suddenly hot and wet with fresh excitement.
Ah... what Master meant... this feeling?
Watching Su-hui walk away with his cum filling her, the teaching assistant felt his cock harden again.
"From tomorrow... let's begin... see how lewd Su-hui can become..."
