Amanda stood nervously outside, her heart racing in anticipation of what was to come. She couldn't believe she'd actually agreed to this unusual request, but something about it had drawn her in - the taboo thrill of it all, perhaps.
She glanced around, making sure they were alone. Slowly, she pulled up her skirt and exposed her round, plump ass to the air. A wave of arousal washed over her as she imagined him watching her, eager for what was about to happen.
Minutes ticked by, each one feeling like an eternity as she waited for him to arrive. Finally, she saw him approaching from across the park, his eyes locked onto hers. Without saying a word, he made his way towards her, his cock already hard and thrusting against his pants.
Amanda couldn't contain her excitement any longer; she wanted this so much. She bent over at the waist, presenting her supple ass to him as he approached. His hands immediately went to work, tearing off her panties and exposing her pink, puckered anus.
Without any further prompting, she felt him pressing against her from behind. He thrust forward, pushing his cock deep inside her tight rectum. A groan escaped her lips as pleasure coursed through her body at the intrusion.
As he began to fuck her from behind, Amanda couldn't help but get closer to her climax. She closed her eyes, savoring the sensation as he pounded deeper and harder into her unwilling hole. Finally, with a moan that escaped her lips, she felt her orgasm washing over her, bringing with it a torrent of hot, sticky poop.
She tightened her sphincter muscles, holding onto every last bit of his cock as she pushed out her load. Poop oozed out from around his shaft, dripping down onto the ground beneath them. As the last of it spilled out, Amanda felt a sense of accomplishment wash over her.
Opening her eyes, she gazed at his jizz-covered cock before turning around to face him. Their eyes locked, and for a moment they just stood there in silence. Then, as if snapping out of a trance, he broke the spell by erupting once more - this time, all over her beautiful curvy body.
The feeling of his warm semen dripping down her skin only served to heighten her arousal. She reached for him, pulling him closer as she wrapped her arms around him in a tight embrace. They stayed there like that for what felt like an eternity, lost in each other's eyes until eventually, their passion began to wane.
Slowly, they pulled apart, both still breathing heavily from their encounter. Amanda looked down at her soiled clothes, feeling a mix of embarrassment and excitement surging through her veins. Without saying a word, she turned around and began to walk away, leaving him standing there, his cock still visibly hard inside his pants.
As she made her way home, she couldn't help but relive every moment of their encounter. The feeling of his cock inside her, the taste of her own poop on her tongue, the look of pride on his face as he watched her shit on him. She knew this was just the beginning - there was something special about this, something that she couldn't resist. And with that thought lingering in her mind, she prepared herself for what was to come next.
