The school bell had rung long ago, leaving the hallways of Westridge High silent and empty. Molly, an 18-year-old senior with long brunette hair, stood outside the maths classroom, her heart racing. She was of medium height, curvy in all the right places, but it was her impossibly huge breasts that always drew the most attention. Today, they strained heavily against the buttons of her white school blouse, the fabric stretched tight across her chest. She had just flunked her final maths exam. A D. That single grade would almost certainly destroy her chances of getting into the university course she had dreamed about for years. Desperate, she pushed open the classroom door.

Mr. Ling, a 40-year-old overweight maths teacher, was still sitting at his desk, the glow of his computer screen lighting his round face. He looked up as Molly stepped inside, her curvy figure filling the doorway. Her massive breasts jiggled slightly with each step.

“Mr. Ling,” she said softly, closing the door behind her. “I really need to talk to you about my grade.”

He sighed heavily and shook his head, already knowing where this was going. “Molly… the exams are finished. The results are final. You should have studied harder.”

Molly stepped closer, her hips swaying gently. “Please… I can’t lose my place in the course because of one test. I’ll do anything to fix this.”

As she spoke, she rose onto her tiptoes and gave a quick, deliberate bounce. Her enormous breasts wobbled heavily inside her tight blouse, the buttons straining as if they might pop.

Mr. Ling’s eyes flicked down to her chest for the briefest moment before he forced them back up. He stood up from his chair. “There’s nothing I can do,” he muttered, moving toward the door to usher her out.

Molly quickly stepped in front of him, blocking his path. “Pleeeease, Mr. Ling,” she whispered, her voice sweet and pleading. “Are you sure there’s nothing I can do?”

She reached down and boldly placed her hand directly on the growing bulge in the front of his trousers.

Mr. Ling gasped sharply, his entire body stiffening. His mouth opened, but no words came out. He stood frozen as Molly began slowly rubbing her palm against his cock through his pants. He could feel himself hardening rapidly under her touch.

Sweat broke out across his forehead. His mind screamed at him — the rules, the regulations, his career, everything he could lose in a single moment. This was insane. Dangerous. Wrong.

He managed a weak, “No…”

But Molly didn’t stop. She gripped his thickening cock more firmly through the fabric and stroked him with slow, confident movements. Mr. Ling’s breathing grew ragged. He squirmed in place, internally panicking, yet his body refused to pull away. The pleasure was too intense, too sudden.

Molly smiled softly. Without a word, she unbuckled his belt and unzipped his trousers, freeing his hard, thick cock. It sprang out heavily into her hand. She wrapped her soft fingers around it and began stroking him properly, sliding her hand up and down his shaft.

Mr. Ling groaned deeply, his hips twitching forward despite himself. He grabbed her wrist for a moment, whispering hoarsely, “Please… no…”

Molly looked up at him with wide, innocent eyes while continuing to slowly jerk his cock. “Do you want me to stop, Mr. Ling?”

He said nothing. His grip on her wrist loosened. His chest heaved as he breathed heavily, caught between panic and overwhelming lust.

Satisfied with his silence, Molly began unbuttoning her school blouse one button at a time. When she finally pulled it open, her massive breasts spilled forward, barely contained by her white lace bra. Mr. Ling’s eyes widened, fixed on the deep cleavage and the way her huge tits overflowed the cups.

She reached behind her back, unclasped her bra, and let it drop to the floor. Her enormous bare breasts bounced free — heavy, round, and impossibly large, with soft pink nipples that had already stiffened. They were breathtaking.

Molly took Mr. Ling’s trembling hands and placed them firmly onto her massive tits. The moment his fingers sank into the soft, warm flesh, he let out a shaky breath. They felt even better than they looked — so full and heavy in his palms.

Molly whispered, “If you squeeze them… I’ll play with that lovely cock of yours.”

Mr. Ling hesitated only for a second before his hands began greedily squeezing and kneading her enormous breasts. Molly rewarded him by stroking his cock faster, her grip firm and slick.

He whimpered with pure pleasure, his fingers digging deeper into her soft titflesh.

Molly gently pushed him backward until he dropped heavily into his desk chair. She sank gracefully to her knees between his spread legs, her massive bare breasts swaying pendulously as she moved. Leaning forward, she took his throbbing cock into her warm, wet mouth and began bobbing her head up and down, sucking him with slow, sloppy strokes.

Mr. Ling let out a stifled cry, his hands gripping the arms of the chair tightly. The sensation was almost too intense.

After a long minute of her skilled oral attention, Molly pulled off his cock with a wet pop and looked up at him, her lips glistening.

“How about we put this between my big tits?” she asked softly.

Mr. Ling stared down at her enormous breasts, then closed his eyes and nodded frantically, his breathing ragged.

Molly smirked. She lifted her massive tits, spread them apart, and nestled his slick cock deep into the warm, silky valley between them. She held her breasts open for a moment, looking up at him expectantly.

Mr. Ling was panting, desperate, his hips twitching with need. Why had she stopped?

Molly’s voice was sweet but firm. “How about we change those grades first?”

He didn’t hesitate. Leaning over with shaking hands, Mr. Ling woke his computer, logged in, and pulled up Molly’s results. With frantic clicks and typing, he erased the D and replaced it with a solid A+. He hit submit.

The moment the grade was saved, Molly smashed her enormous breasts together around his cock, enveloping him completely in soft, pillowy flesh.

Mr. Ling yelped loudly in shock and ecstasy.

Molly began sliding her heavy tits up and down his shaft in long, smooth strokes. The sight of his cock disappearing between her massive breasts drove him wild. He moaned and whimpered helplessly, his hands eventually returning to grope and squeeze her tits as she worked him. Suddenly something inside him snapped. Mr. Ling stood up abruptly, kicking his chair back. He grabbed Molly’s shoulders and started thrusting aggressively between her tits, fucking them hard and fast. Molly gasped but held her breasts tightly together for him, letting him use her massive chest.

It didn’t last long.

His thrusts grew erratic and desperate. Strange, guttural noises escaped his throat as his knees began to buckle. Molly quickly reached around and gripped the back of his thick thighs, steadying him as he slammed his cock between her tits one final time.

With a loud, broken yell, Mr. Ling came violently.

Thick, powerful ropes of cum erupted from his cock, splattering across Molly’s pretty face, her neck, and the tops of her enormous breasts. He kept thrusting weakly through the orgasm, grunting and shuddering as he emptied himself completely.

When it was finally over, he pulled away on shaky legs, breathing hard. Molly smiled sweetly as she used some tissues from his desk to clean the mess off her face and chest. She casually buttoned her blouse back up, her huge tits still straining against the fabric.

She gave him one last mischievous look as she headed for the door.

“See you around, Mr. Ling.”
