Yes, you fuck her

“Yes.” The word tasted like ash, even as you caved to her offer, to the desire that was a part of you.

She stood up, a fluid motion, and stepped over her bag, the notebook now partially hidden by her leg. She hiked her athletic shorts up, the fabric straining over her ass, then simply pulled the waistband to the side. No underwear. The simple, brazen exposure of it, in the middle of a lecture hall, made you even more erect, if such a thing were possible.

She didn’t wait, didn’t ask. She just lowered herself onto you, her body blocking your view of the pulsing notebook in her bag. Her cunt was soaked, a slick, burning heat that enveloped your cock inch by brutal inch, and her muscles clenched around you with a practiced, greedy tightness. “Fuck,” she hissed through clenched teeth, her athletic thighs trembling as she took you all, settling into your lap with a final, grinding drop of her hips.

Your hands went to her waist, feeling the defined ridges of muscle beneath her skin, the proof of her relentless training. She began to move, a slow, deliberate roll that was maddeningly controlled. Around you, the lecture hall’s other activities continued—the slapping, the groans, the professor’s uninflected voice listing the laws of motion. “See?” Bell panted, her breath hot against your neck. “We’re just part of the syllabus. Natural law.”

But your law was written in that black book. As she rode you, the pleasure a thick, narcotic fog, your mind clawed at the ghost-memories. The hallway. Colton and Kiersten. The way the world had simply bent to accept it. Each rise and fall of Bell’s hips was a hammer blow nailing you deeper into her fabricated reality. You fought to keep your face slack, your eyes glazed with what she would read as lust. Inside, you were screaming.

“You feel so fucking good inside me, Zay,” she moaned, louder now, wanting an audience. Her hand fisted in your hair, yanking your head back. “Tell me you love it. Tell me you love your sister’s pussy.”

The words were a test. A command scripted in invisible ink. Your gut churned. You buried your face in the sweaty hollow of her neck, your voice a raw grunt against her skin. “I love it.” The lie was acid, but it fed the fiction. It kept you alive.

Her pace quickened, becoming frantic. She bounced on your cock, each impact jarring your spine, her ass slapping against your thighs. The sound was obscenely loud, wet and meaty. “Yeah, just like that,” she chanted, her composure shredding. “Gonna make me come right here in front of everyone. Give it to me.”

You had to perform. You gripped her ass, fingers digging into the firm flesh, and drove up into her, meeting her descent with a force that made her cry out. It wasn’t passion. It was a excavation. You fucked her with a desperate, focused violence, trying to bury the truth under a mountain of sensation. Her tits bounced in her tight tank top, and she tore the neckline down, freeing them, not caring who saw.

“Harder,” she demanded, her nails scoring your scalp. “Come in me. I want it. I want your fucking load, brother.”

Did you obey out of your own desire, or something created? It didn't matter, because either way the climax ripped through you, a convulsive, unwilling surrender. You slammed up into her one last time, holding her down, and erupted, pulse after pulse of hot semen flooding her. She clenched around you, milking you dry, her own orgasm a silent, shuddering vibration that lasted for what felt like minutes.

She went limp against you, panting. The professor began writing a new equation on the board. The couple to your left was now just cuddling. The world had not ended. It had simply absorbed another obscenity.

Bell nuzzled your neck, your own spend leaking between her thighs and onto your jeans. “Perfect,” she whispered, content. She reached down, grabbed her bag, and pulled the notebook out, resting it on your chest as she stayed impaled on you. She flipped it open with one hand, uncapping a pen with her teeth. You stared at the ceiling, the aftermath cold in your veins, as the sound of her pen scratching fresh words into reality filled the silence between your heartbeats.
