The late afternoon sun cast long shadows across the Shanghai Imperial University campus, but inside the principal's private office on the top floor, the air was thick with tension and the faint smell of stale cigarettes and cheap cologne. Ye Chen remained seated cross-legged on his simple first-year dormitory bed, eyes closed, divine sense extended like an invisible, crystal-clear lens directly into the principal's office. His immortal perception captured every detail without flaw — every breath, every rustle of clothing, every filthy syllable that left the old man's mouth.
After thousands of years at the peak of cultivation, true excitement had become a rare commodity. But this new game — watching his flawless immortal wives willingly submit their perfect bodies to the most pathetic, unworthy mortal men — had reignited a dark fire in his blood that nothing else could match. The contrast was intoxicating: god-like women of supreme beauty and power, reduced to playthings for greedy, disgusting mortals, all for Ye Chen's private pleasure.
Today, the game continued with Teacher Zheng.
Teacher Zheng stood once again in the center of the principal's luxurious office, her mature, voluptuous body on full display in her usual professional attire. As the university's respected biology teacher, she carried an air of intellectual authority that only made her physical perfection more obscene. Her massive D-cup breasts strained heavily against the crisp white blouse, the thin fabric stretched so tightly that the outline of her bra was faintly visible beneath. The blouse was tucked neatly into a tight black pencil skirt that clung desperately to her slender waist before flaring out over her enormous, round, juicy ass. Sheer black stockings encased her long, shapely legs, ending in modest black heels. Her long black hair was pinned up in a neat bun, thin silver-framed glasses perched on her elegant nose, giving her the perfect image of a strict, knowledgeable, and irresistibly seductive biology professor.
Principal Wang lounged behind his massive mahogany desk, the 58-year-old bald man's fat belly spilling over his belt. His small, pig-like eyes gleamed with raw hunger as they roamed shamelessly over her chest and hips. He had already sent the message demanding her presence, and now that she had arrived and locked the door behind her, he wasted no time.
"Teacher Zheng," he began, voice oily and commanding, "I've been thinking about your role here at the university. As a biology teacher, you're supposed to be an expert on the human body, right? Very detailed knowledge." He licked his lips, leaning forward. "I've decided I need some… private tutoring. Sit down. Right here."
He patted his thick thigh, his fat hand resting on his lap.
Teacher Zheng stood motionless for a brief moment, then sent a calm, devoted mental message through their immortal bond:
"Master… he wants me to sit on his lap. He's framing it as a biology lesson. Shall I obey completely?"
Ye Chen's cock twitched hard inside his pants the instant he received the message. His hand moved slowly downward, gripping himself through the fabric as he replied mentally, voice steady but thick with dark arousal:
"Obey everything. Sit on his lap exactly as he orders. Teach him whatever he asks. Make it educational… but let him turn it filthy. Suppress every real reaction. I want to hear every dirty word and feel every touch through your reports. This is perfect."
Teacher Zheng obeyed without hesitation. She walked around the desk, her huge ass swaying slightly in the tight skirt, and lowered herself carefully onto Principal Wang's lap. Her enormous, plump ass cheeks settled heavily onto his fat thighs, the pencil skirt riding up slightly from the position. Her massive D-cup breasts were now only inches from the old man's greasy face. The heat of his body and the hard lump of his small erection pressed up against her through his pants.
Principal Wang let out a low, satisfied groan, his fat hands immediately landing on her hips to pull her closer. "That's better. Much better. Now, Teacher Zheng, since you're the expert, I want you to teach me about the human body. Start with the most interesting parts… those big, heavy tits of yours."
His voice was crude and dripping with lust as he stared directly at her chest.
Teacher Zheng kept her expression professional and slightly hesitant, as if this were an awkward but necessary lesson. Through the bond she reported calmly:
"Master… I'm on his lap now. His erection is pressing against my ass. He just called my breasts 'big heavy tits' and wants me to teach about them. He's very excited already."
Ye Chen stroked himself slowly, savoring the mental image. "Good girl. Start teaching. Let him touch when he wants. Describe everything to me."
Teacher Zheng adjusted her glasses slightly and began in her clear, educated biology-teacher voice, even as she sat on the old man's lap:
"Principal Wang… the female breast is a complex organ. It consists of glandular tissue, fat, and connective tissue. The external part you're looking at is primarily adipose tissue covered by skin, with the nipple and areola being the most sensitive areas."
Principal Wang chuckled filthily, his fat hands sliding upward from her hips to cup the underside of her massive D-cup breasts through the blouse. He squeezed them roughly, feeling their heavy weight and softness.
"Mmm… keep teaching, Teacher Zheng. Tell me more about these big tits. They feel so fucking full and soft. Are they supposed to be this heavy? Fuck, I can barely hold one in my hand."
His fingers dug into the soft flesh, kneading and lifting her breasts as if weighing them. The white blouse stretched even tighter over the massive mounds.
Teacher Zheng suppressed the faint sensation, keeping her voice steady at first. "The average female breast weighs between 200 to 400 grams, but larger ones like… these… can be significantly heavier due to higher fat and glandular content. The… ah… shape and size vary based on genetics and hormones."
Principal Wang's thumbs moved upward, circling over her nipples through the layers of blouse and bra. He pinched them lightly at first, then harder, rolling the hardening buds between his fat fingers.
"Like this?" he asked dirtily. "I'm pinching your nipples right now through your clothes. They're getting hard already. Is that normal in a biology lesson, Teacher Zheng? Or are you getting excited teaching an old man about your own slutty tits?"
Teacher Zheng bit the inside of her cheek, suppressing any real reaction, but she let a soft, controlled breath escape. Through the bond:
"Master… he's squeezing my breasts hard and pinching my nipples through the blouse. His fingers are rough. He's calling them slutty tits. I'm keeping my voice educational."
Ye Chen's cock throbbed in his hand as he stroked faster. "Perfect. Moan a little when he pinches harder. Let him demand more."
Principal Wang pinched her nipples again, twisting them slightly through the fabric. "Answer me, Teacher. Your nipples are so stiff already. Tell me what happens when I do this."
A soft, suppressed moan slipped from Teacher Zheng's lips. "Ah… when stimulated, the nipples become erect due to contraction of smooth muscle fibers. This is a normal physiological response… even in non-lactating women."
The old man laughed lewdly, continuing to roll and pinch her nipples harder. "Non-lactating, huh? But these big tits look like they could produce milk any second. Keep teaching. Tell me exactly where the milk comes from and what makes it come out."
Teacher Zheng's voice remained mostly composed as she explained, even while his hands mauled her chest:
"The milk is produced in the mammary glands… inside the breast tissue. During pregnancy or… strong excitement… the glands can activate and… mmm… produce small amounts of fluid. The milk ducts lead to the nipple, where it would be expressed."
Principal Wang's eyes lit up with filthy interest. "Strong excitement? Like what we're doing right now? Your nipples are so hard they're poking through your blouse. I can feel them perfectly." He pinched and pulled them outward, stretching the fabric. "Show me properly. Remove the blouse. I want to see these tits without clothes in the way. That's part of the lesson, isn't it?"
Teacher Zheng paused for a moment, then slowly unbuttoned her white blouse, revealing a lacy black bra that barely contained her massive D-cup breasts. She shrugged the blouse off her shoulders, letting it fall to the floor. Her heavy, pale breasts spilled forward, straining against the thin bra cups.
Principal Wang groaned loudly, his small cock twitching against her ass. "Fuck… look at those huge tits. So pale and heavy. Now the bra too. Take it off. I want full access for the biology lesson."
She reached behind her back, unclasping the bra and letting it slide down her arms. Her massive D-cup breasts bounced free, heavy and perfectly shaped, nipples already stiff from the earlier pinching. The cool office air made them look even more obscene.
Principal Wang immediately grabbed them with both hands, squeezing the bare flesh roughly. "Mmm… much better. Now continue teaching, Teacher Zheng. Explain the nipple again while I play with them."
His fat fingers found her bare nipples and pinched them hard, rolling them between thumb and forefinger, then pulling them outward and letting them snap back. He repeated the motion over and over, watching her heavy breasts jiggle with each tug.
Teacher Zheng's breathing hitched slightly, but she kept her voice as educational as possible, sending constant mental updates to Ye Chen:
"Master… he has removed my blouse and bra. He's pinching and rolling my bare nipples now. They're very sensitive but I'm suppressing it. He keeps pulling them."
Ye Chen was fully stroking his cock now, pre-cum leaking as he watched the scene unfold in perfect detail.
"The nipple… ah… contains many nerve endings," Teacher Zheng continued, a soft moan slipping into her words despite her efforts. "When… when rolled or pulled like this… it stimulates the smooth muscle and… mmm… can cause further erection and… increased blood flow."
Principal Wang laughed dirtily, twisting both nipples at once. "Keep going, you slutty teacher. Your tits are bouncing every time I pull. Tell me more about the milk. You said it can come out if a woman is pregnant or excited. Are you excited right now, Teacher Zheng? Because these nipples look ready to leak."
He leaned in, his greasy breath hot against her bare chest, and sucked one stiff nipple into his mouth without warning, swirling his tongue around it loudly.
"Ahh…" Teacher Zheng moaned, the sound more genuine in tone but still controlled. Through the bond: "Master… he just started sucking my nipple. His mouth is wet and greedy. He's asking if I'm excited enough for milk."
Ye Chen's arousal spiked higher. "Answer him. Explain everything while he sucks. Moan more. Let him think he's making you lose control."
Principal Wang popped the nipple out of his mouth with a wet smack and looked up at her with lust-filled eyes. "Answer properly, Teacher. Is milk supposed to come out right now? Or do I need to suck harder to make it happen? Tell me the biology while I taste these fat tits."
Teacher Zheng's voice trembled slightly as she answered, her massive breasts heaving with each breath:
"If a woman is pregnant… the mammary glands produce colostrum and then milk… but even in non-pregnant women… strong… ah… stimulation and excitement can cause small amounts of fluid to be expressed from the ducts. It's… mmm… a natural response to… intense nipple stimulation."
Principal Wang grinned wickedly and latched onto her other nipple, sucking harder this time, his fat lips pulling the stiff bud deep into his warm, wet mouth. He rolled it with his tongue, then used his teeth to graze it lightly while his hand continued mauling and pinching the other breast.
"Like this?" he mumbled around her nipple, the words muffled and obscene. "I'm sucking your tit like a baby, Teacher Zheng. Does this count as practical biology? Your nipple is so hard in my mouth. I can feel it throbbing. Keep teaching — tell me if you're getting excited enough for milk to come out."
Teacher Zheng moaned softly, suppressing the real sensations but letting enough slip through for his satisfaction. "Yes… Principal Wang… this level of… ah… stimulation on the nipple and areola… can activate the let-down reflex even without pregnancy… if the woman is… sufficiently aroused… small drops of fluid… might be expressed…"
The old man sucked even more greedily, switching between both breasts, licking, sucking, and biting the stiff nipples while his hands squeezed the heavy flesh around them. Wet, sloppy sounds filled the office as he nursed on her like an animal.
"Fuck… these tits are perfect," he groaned between sucks. "So big and soft. I could suck them all day. Tell me more, Teacher. What if I bite a little harder? Does that make more milk come? Or should I squeeze your tits while I suck?"
He demonstrated by grabbing both massive breasts and squeezing them toward the nipples while sucking hard on one, as if trying to milk her.
Teacher Zheng's moans grew a fraction louder despite her suppression. "Biting… or firm squeezing… can increase the pressure on the milk ducts… ah… making any potential fluid… more likely to… mmm… express itself…"
Principal Wang pulled back for a moment, strings of saliva connecting his lips to her swollen, glistening nipples. "Then let's do a full practical demonstration. I'm going to suck these fat tits until something comes out. And you're going to keep explaining every second like a good biology teacher."
He buried his face between her massive D-cup breasts again, sucking one nipple deep and hard while pinching and rolling the other. His free hand slapped the side of her heavy breast lightly, making it jiggle.
Teacher Zheng continued her "lesson" between suppressed moans, sending live mental reports to Ye Chen the entire time:
"Master… he's sucking very hard now… biting and pulling my nipples while squeezing my breasts. He's demanding a practical demonstration for milk. His mouth feels wet and desperate. I'm keeping my explanations going for him."
Ye Chen stroked himself steadily in the dorm, edging closer to release but holding back, completely absorbed in the filthy scene. The sight of his elegant, big-breasted immortal wife sitting half-naked on the lap of this disgusting bald old principal, explaining biology in a trembling voice while her nipples were sucked and mauled, was pure ecstasy for his bored immortal soul.
Principal Wang kept sucking noisily for long minutes, switching breasts constantly, his hands never leaving her heavy tits. He asked more dirty questions between loud slurps:
"Tell me, Teacher — are your nipples always this sensitive? Or only when an old man like me is sucking them?"
"Do you feel milk starting to build up yet? Because I'm sucking as hard as I can."
"These tits are so fucking milky-looking. Keep moaning while you teach me, slutty professor. I love how your voice shakes when I bite down."
Teacher Zheng answered every question with detailed, scientific explanations laced with soft, reluctant moans, exactly as Ye Chen desired. Her massive breasts glistened with the principal's saliva, nipples red and swollen from the relentless sucking and pinching.
The "biology lesson" continued deep into the evening, the old man's greedy mouth and hands exploring her chest as if he owned it, while Teacher Zheng remained perfectly obedient on his lap, feeding both the principal's ego and her Master's dark pleasure through every filthy word and suppressed sound.
In the dormitory, Ye Chen finally allowed himself a slow, powerful release, his immortal seed spilling as he watched the scene reach its peak. This was the cure he had been searching for across eternity.
When Teacher Zheng finally left the office much later, her blouse slightly disheveled and her nipples still sensitive beneath it, she sent one final devoted message to Ye Chen:
"Master… the lesson is over for today. He sucked until he was satisfied. Shall I prepare for tomorrow's session?"
Ye Chen smiled darkly, already anticipating the next chapter in his wives' willing degradation.
