Aislinn grinned as she slipped off her jeans, revealing her black thong that adorned her perfectly round ass. She always wore thongs, knowing that they accentuated her tight little backdoor and made it appear as if she were constantly stuffed full of something. It was part of her kink, her love of teasing and denying herself the release she so desperately craved.
She sat down on the bed, carefully arranging herself so that the thin scrap of fabric between her ass cheeks was on full display. Her heart raced as she began to play with her pussy, her fingers sliding slowly over her slick folds. She moaned softly, feeling herself getting wetter as she imagined what it might feel like to be fully taken, her ass stretched open by a massive cock filling her up completely.
She paused for a moment, breathing heavily as she gazed down at her reflection in the mirror. Her tan skin glowed in the soft light, and her large breasts jiggled slightly with each ragged breath. A trickle of pre-cum dripped out of her slit, and she licked her lips greedily. The sensation of her own wetness was driving her wild with desire.
Just as she was about to give in to the urge to rub her clit harder, she felt something hard pushing against her ass crack. She froze, her eyes widening in shock. It felt like another finger, long and warm and unyielding. But how? She was alone in her room, and she was certain she hadn't left any toys out.
She gasped as she felt another hard push, this time against her puckered little hole. Whatever it was, it was unyielding and insistent. Suddenly, she knew what was happening. It was her own monster shit, trapped inside her, pushing its way out. Her knees weakened as she felt another surge of pressure, and she knew she couldn't hold it in much longer.
Slowly, she leaned forward, giving her monster shit a clear pathway out. She gasped as she felt the head of her poop slip through her slick folds and press against her bare pussy lips. She moaned loudly as the pressure built inside her, and with a loud grunt she pushed as hard as she could.
A massive log of steaming hot shit slid out of her gaping ass, coating her fingers and sliding down her legs as it hit the floor. Aislinn's breath came in ragged gasps as she watched in a mixture of horror and arousal. She had never been so turned on in her life. She pulled her legs up to her chest, revealing the messy pile of shit that covered her panties, and then licked her lips once more, tasting the tangy sweetness of her own waste.
She reached down and rubbed the goo between her fingers, smearing it over her swollen clit until she could feel it throbbing against her fingertips. She groaned loudly as the intense sensation built up inside her, threatening to send her over the edge. And then, finally, she orgasmed, her body shuddering with the force of it as she came hard all over her messy pile of shit.
When she finally came down from her high, she felt an odd sense of satisfaction wash over her. She grinned as she pulled her panties off, the caked-on shit flaking off in chunks as she tossed them aside. "That was amazing," she whispered to herself, still caught up in the haze of the experience.
As she leaned back against her pillows, her mind wandered back to the monster pushing her panties. The idea that something so dark and dirty could be so intensely arousing filled her with a mix of fear and excitement, and she knew that she would have to explore this side of herself further. But for now, as she drifted off to sleep, all she could think about was the feel of hot monster shit pushing its way out of her tight little ass, and the taste of her own waste on her lips.
