Professor Harlan's 9 a.m, Advanced Literature lecture was packed, but the back row stayed suspiciously empty except for Lila.
She arrived five minutes late on purpose, wearing the same short red-and-black plaid skirt from the book cover, white cropped blouse tied under her breasts, black lace bra barely containing her. No panties. Again.
Jax sat at the front beside his father, playing the perfect TA: calm, professional, clicking through slides. But when Lila walked in, his eyes flicked up, dark with promise. Marcus was already in the back row, legs spread wide, smirking as she slid into the seat beside him.
Under the desk, his hand immediately found her thigh and slid higher.
"Miss Voss," Professor Harlan called from the front, "nice of you to join us. Care to share your thoughts on last night's reading?"
Lila's breath hitched as Marcus's fingers brushed her bare, soaked pussy. "I… uh… found the themes of forbidden desire particularly… intense."
Jax's lips twitched. He knew exactly what she was feeling.
Marcus didn't waste time. Two fingers pushed inside her right there in the middle of class. Slow, deep strokes while the lecture continued. The wet, obscene sounds were masked by the professor's voice and the scratch of pens on paper. Lila gripped the edge of the desk, biting her lip hard to stay quiet.
Then Jax stood. "I'll pass out the quiz sheets," he announced smoothly, walking the aisles like nothing was happening.
He reached their row last. Leaning over to hand Lila her paper, he slipped something small and smooth into her hand under the desk a sleek, black remote-controlled vibrator, egg-shaped and already slick with lube.
"Put it in," he whispered so only she could hear. "Now."
Heart pounding, Lila spread her legs wider under the desk. Marcus helped, holding her skirt up while she pushed the toy deep inside her dripping pussy. The moment it was seated, Jax still at the front clicked the remote in his pocket.
Low vibration hummed to life.
Lila jerked, a tiny whimper escaping before she could stop it. A few heads turned. Marcus chuckled softly and slid his hand back between her thighs, pressing the toy deeper while Jax ramped up the intensity from the front of the room.
The lecture continued. Slides changed. Students took notes.
Lila was falling apart.
The vibrator buzzed relentlessly against her G-spot while Marcus's fingers circled her swollen clit. Her thighs trembled. Juices coated the chair. She gripped Marcus's wrist, silently begging, but he only grinned and pushed a third finger in alongside the toy.
Jax caught her eye from the front and turned the vibe to its highest setting.
Pleasure slammed into her like a freight train. Lila came hard silently, violently biting down on her own fist to keep from moaning out loud. Her pussy clenched and fluttered around the toy and Marcus's fingers, a small gush of wetness soaking the seat beneath her. Stars burst behind her eyes.
Professor Harlan kept talking, completely unaware that his son was remotely fucking one of his students in the back row.
When the orgasm finally ebbed, Jax turned the toy off. But he wasn't done.
"Group discussion time," he announced. "Pair up with the person next to you and analyze the symbolism of hidden desires in the text."
Marcus didn't even pretend to discuss literature. He unzipped quietly, pulled his thick cock out under the desk, and guided Lila's hand to it. She stroked him slowly while pretending to take notes, her own arousal still dripping.
Jax walked the room again, "supervising." When he reached their desk, he leaned down as if checking their work and whispered, "Bathroom. Five minutes. Both of you. Leave the toy in."
Lila barely made it through the next few minutes without coming again.
The moment the professor turned to the whiteboard, she and Marcus slipped out. They didn't even make it to the bathroom. Jax met them in the empty hallway just outside the lecture hall, shoved them both into the small supply closet beside the door, and locked it.
Clothes came off in seconds.
Jax bent Lila over a stack of boxes, yanked the still-buzzing vibrator out, and replaced it with his cock in one brutal thrust. Marcus stood in front, feeding her his dick while Jax fucked her senseless from behind hard, fast, the slap of skin dangerously loud so close to the ongoing lecture.
"Such a good little campus slut," Jax growled, spanking her ass red. "Coming in my father's class like a whore."
Marcus groaned, holding her hair. "Swallow every drop this time."
They used her relentlessly switching positions, filling her mouth and pussy, then both at once again. Lila came twice more before they finally unloaded: Jax deep inside her, Marcus painting her tongue and breasts.
Breathing hard, covered in sweat and cum, Lila fixed her clothes as best she could. The toy went back in still on low set by Jax with a wicked grin.
"Back to your seat, Miss Voss," he said, kissing her swollen lips. "Class isn't over yet. And neither are we."
She walked back into the lecture hall on shaky legs, the vibrator humming softly, cum trickling down her inner thigh under her skirt, knowing the entire day was only going to get filthier.
