In a dimly lit room, filled with the musky scent of sex and sweat, Ally lay naked on all fours, her heart pounding in anticipation. She had always been adventurous when it came to sex, but this was something completely out of her comfort zone. She was about to become a human toilet for another person.
Her partner for the evening, a man named Mark, stepped into the room confidently, his cock already hard and standing straight up. He approached Ally slowly, admiring her curvaceous body and perfect round ass. He knew tonight was going to be incredible.
Without saying a word, Mark positioned himself behind Ally and pushed his cock against her wet pussy lips. Ally let out a moan as he slowly penetrated her, filling her up with his massive cock. As he began to thrust deep into her, he grabbed her hips and guided her towards a messy pile of dog shit on the floor.
"Say it," he commanded.
"I love dirty sex," she moaned, her voice shaky with excitement. "I love being your human toilet."
Mark's thrusting intensified as he felt Ally's ass tighten around his cock. He continued to push her closer to the pile of shit until she was finally positioned directly above it. Slowly, he pulled out of her and aimed his huge cock at the pile.
"On three," he said. "One... two... three!"
Hot cum shot out of Mark's cock and landed all over Ally's face and in her mouth. She opened her mouth wide, taking it all in. As she tasted the salty cum mixed with the hint of dog shit, she felt a rush of sexual pleasure unlike anything she had ever experienced before.
Mark pulled out of her completely and collapsed onto the bed, breathing heavily. He watched as Ally leaned over and began to spread the mess around her face and in her mouth, savoring every bit of it.
"That was amazing," she said, crawling over to him. "Can we do it again?"
Mark grinned widely. "Of course, babe. You're the best human toilet I've ever had."
And so, their dirty, passionate journey began. Ally became his personal human toilet, and she loved every single messy second of it.
