"Kai, no... we... can't..."
Yun Xi's voice was a tremble, a whisper of resistance that lacked any real conviction. She looked at him with wide, watery eyes, caught between the ingrained modesty of a shy girl and the burning, academic curiosity of a scholar who had just found the ultimate subject.
Kai watched her face closely.
Fuck, he thought, his mind racing. I know what I have to do. It's risky. One wrong move and she screams for her mother. But I can see it... the shyness is just a veil. Behind it, she's dying to know.
He had to bridge the gap. Words weren't enough.
"Yun Xi," he whispered.
He didn't pull away. Instead, he took her hand—the one that had been resting tentatively on his chest. His palm was hot, enveloping her smaller, trembling fingers.
He moved it.
He guided her hand down, sliding it over the buttons of his uniform, past his belt buckle.
He pressed her open palm directly onto the tented fabric of his trousers.
"Ah!"
Yun Xi gasped, her breath hitching violently in her throat.
She froze. Beneath her palm, through the thin fabric of his Academy trousers, she felt something impossibly hard. It was warm, solid, and thick—a rigid bar of iron that seemed to pulse against her skin.
"Well," Kai murmured, his voice thick with suggestion. "If you don't want to see it... then you can just feel it. Just one time."
Yun Xi didn't pull away. Her eyes widened, her pupils dilating as her brain tried to process the sensory input. It wasn't soft like a limb. It was dense. It was alive.
It... it feels so big, Yun Xi thought, her mind reeling. No, Yun Xi, you can't think like that! But... oh god, the shape... I wonder how it looks compared to my drawings?
"You can rub it, Yun Xi," Kai coaxed gently, watching her face flush darker. "If you want. Feel it more. Just for science."
Yun Xi said nothing. She couldn't speak. Her throat was dry.
Slowly, hesitantly, her fingers curled.
She squeezed.
Throb.
The cock beneath the fabric jumped in response to her touch.
"Oh..." she moaned softly.
She began to move her hand. She traced the long, thick length of the shaft, feeling the ridge where the head began. She rubbed her palm up and down, fascinated by the heat radiating through the cloth. It was mesmerizing. It was dangerous.
Just as she was getting into a rhythm, her breathing becoming shallow and rapid, Kai made his move.
He placed his hand over hers.
And he pulled it away.
"Kai?" Yun Xi whined, a sound of pure disappointment escaping her lips. Her hand hovered in the air, her fingers twitching, missing the warmth. "What happened? I was... I was admiring it."
She blushed furiously at her own words, realizing how wanton she sounded.
Kai stepped back, putting a cruel inch of distance between them. He adjusted his trousers, hiding the bulge from her touch.
"You said, Yun Xi," Kai said, his voice calm but laced with feigned disappointment. "You said you don't want to see it. So it's okay. I respect that. I think we should just study something else. Maybe history?"
He turned slightly, as if to walk toward the desk.
Panic seized Yun Xi. The thought of stopping now—of going back to boring books when the mystery was right there—was unbearable.
"No!"
She grabbed his arm, squeezing her eyes shut tight.
"No, Kai... please no!" she begged, her voice desperate. "You are right! We are friends! And... and friends should help each other, right? We shouldn't hide from each other!"
She opened her eyes, looking up at him with a mix of fear and intense desire.
"Please... don't stop."
Kai looked down at her, suppressing a triumphant grin.
"So you want to?" Kai asked.
Yun Xi looked around the room nervously, checking the locked door, then looked back at his crotch.
"Yes," she whispered. "I want to."
"But promise me," Kai said, leaning in. "It will only be between us. You will not tell this to anyone else. This is our secret study session."
"Of course, Kai," she nodded vigorously, her heavy breasts bouncing. "I promise. I will not tell a soul."
She bit her lip, staring at his zipper.
"So... then?"
Kai looked at her eager face. "You first? No... I'll go first."
He reached for his belt. Click.
He undid the button. Pop.
He lowered the zipper. Zzzzp.
Yun Xi held her breath.
Kai hooked his thumbs into his waistband and shoved his trousers and boxers down in one fluid motion.
Boing.
His cock sprang free.
It didn't just hang; it stood at attention. It was massive, thick, and pulsating with life. The skin was taut, veins wrapping around the shaft like vines on a tree trunk. The head was a dark, swollen mushroom cap, glistening wetly with a bead of clear precum at the slit. It twitched in the cool air of the room, angry and hard.
Yun Xi's eyes went impossibly wide. Her mouth fell open into a perfect 'O' shape.
She stared. She didn't blink. It was nothing like the biology books. It was far more intimidating than her sketches.
"It's... big..." she whispered, her voice trembling with awe.
She leaned closer, adjusting her glasses to get a better look.
"It's bigger than I've imagined... and it looks so hard and angry..."
She looked up at Kai, her face glowing with the joy of discovery.
"Kai... it's truly beautiful."
Unable to resist, she reached out. Her hand trembled as she moved to touch the exposed purple head.
Just inches before contact, Kai grabbed her wrist.
"Stop."
Yun Xi froze, looking up at him in confusion. "Kai?"
"You forgot something, Yun Xi?" Kai asked, his voice low and commanding. "Friends help each other. I showed you mine."
He looked pointedly at her oversized beige tunic.
"Now it's your turn."
Yun Xi blinked. The realization hit her.
"Ahh... yes," she whispered, her face turning scarlet again. "I forgot."
She stood up slowly. Her hands went to the hem of her tunic.
She was trembling, but she didn't hesitate. She wanted to touch him, and if this was the price, she would pay it.
She lifted the tunic.
Up over her hips. Up over her waist. Up over her massive chest.
She pulled it over her head and tossed it aside.
She wasn't wearing a bra. She wasn't wearing panties.
She stood before him completely naked.
Her body was a masterpiece of soft, lush curves. Her breasts were enormous, heavy globes of pale flesh that swayed as she lowered her arms. The areolas were large and pink, the nipples hard from the cool air. Her waist was thick and soft, leading down to wide, child-bearing hips.
And between her thighs lay her pussy—plump, untouched, and utterly virgin. It was a neat, vertical slit nestled in soft curls, pink and waiting.
She stood there, exposed and vulnerable, offering herself to his gaze.
"Is... is this okay, Kai?"
