Marina was lost in thought as she sat on the toilet, her eyes closed and her brow furrowed. She let out a deep breath and began to slowly lower her pants, revealing her plump bottom nestled in lacy black panties. As she reached down to adjust herself, her fingers dipped into her cum-filled slit, caressing the sensitive folds and sending shivers up her spine.
She took a fresh pair of red lace panties out of her drawer and placed them on the back of the toilet seat before positioning herself over it. Her warm breath escaped in little puffs as she hovered, anticipation coursing through her body. With one swift push, she sank onto the cold porcelain, her plump cheeks splitting apart to reveal the delicate pink of her rosebud.
Marina gripped the sides of the toilet bowl, her knuckles turning white as she bore down. Her face contorted into a mix of pleasure and pain, and she let out a long, low moan. With each passing moment, the tension grew within her until, finally, she felt the familiar heat spreading between her legs.
Her thighs trembled as she pushed harder, grunting in concentration. The pressure built up inside her until it felt like her insides were glowing. Then, with a loud gush, Marina's ass clamped down around the toilet paper roll bulging from her anus, and she released a torrent of steaming hot feces into the bowl below.
As she pooped, Marina's face contorted into a mix of bliss and mortification. She gripped the sides of the toilet even tighter, her nails digging into the porcelain as her body shook with each powerful push. Loud smacks echoed in the small bathroom as her voluminous logs of poop splashed into the water, creating a small wave around the rim of the toilet.
It felt good. So good to finally empty herself after holding it in for so long. Marina let out a shaky breath, her chest rising and falling rapidly as she caught her breath. When she was finally done, she let out a long sigh of relief and slumped forward against the toilet seat.
She sat like that for a moment, savoring the afterglow of her release. Then, with a groan, she pushed herself up and reached back to wipe her soggy panties clean. As she lifted them to her nose, inhaling the musky scent of her arousal and excretion, she couldn't help but feel a twinge of excitement. Marina was hooked on the thrill of pooping, and there was nothing she could do about it.
