As Ally walked towards the dorm bathroom, her heart raced in anticipation. She was about to indulge in one of her dirtiest secrets, and the thrill of it sent shivers down her spine. Her ass cheeks wiggled slightly under her tight shorts as she moved, teasing the forbidden thoughts that danced in her mind.
Reaching the bathroom door, Ally took a deep breath to steady her nerves. She hated herself for craving this kind of filth, but there was something about the thought of another girl finding out about her dark desires that turned her on even more. With trembling hands, she undid the button on her shorts and lowered the zipper, inching closer to the rush she knew was coming.
Slowly, she slid her shorts down, exhaling sharply as the cool air brushed against her bare ass. She couldn't help but grind against the countertop, feeling the texture against her skin as she leaned forward, presenting her ass to the world outside the stall.
With bated breath, she waited for someone to notice her offering. The sound of footsteps echoing in the distance sent a wave of heat through her core, and she wondered who it could be. Would it be one of her friends, caught off guard by the sight of her exposed ass? Or maybe a stranger, someone who would be repulsed by her filthy desires?
After what seemed like an eternity, she heard a gasp from the other side of the stall door. Her heart leapt with excitement as it dawned on her who it was - her roommate, Grace. Ever since they'd shared a room together at college, Ally had fantasized about her catching her like this.
"Ally, what are you doing?" Grace's voice trembled with shock and arousal, echoing through the gap in the stall door.
"I wanted you to see me like this," Ally whispered, her voice shaking with anticipation. "I need you to help me."
There was a long pause, filled with the sound of heavy breathing and the rustling of clothes. Then, Ally felt a warm tongue trace circles around her asshole, sending waves of pleasure through her body. She closed her eyes, reveling in the forbidden bliss as Grace worshiped her ass.
Moans escaped her lips as Grace continued to lick and tease, her fingers finding their way into Ally's panties. Ally's hips bucked forward, seeking more contact, more of that sweet, sinful feeling that only Grace could give her.
Without warning, Grace stood up and pressed her lips to Ally's ass cheek, slipping a finger into her soaking wet panties. Ally gasped, her knees quaking under the sudden rush of sensation. It felt so taboo, so wrong, but God, it felt good.
"Tell me what you want," Grace murmured into her ear, her breath hot against her skin.
