It was a hot, sultry afternoon and I decided to take a nap in my backyard when suddenly, I heard a noise coming from next door. I sat up groggily, wiping the sleep from my eyes and peered over the fence to see what was going on. To my utter shock and fascination, my sexy next-door neighbor, Sarah, was masturbating on her patio! I couldn't believe my luck - she was wearing a skimpy bikini that barely covered her ample breasts and the way she was grinding her hips against the railing suggested she was getting really close to orgasm.
Before I knew it, the irresistible scent of her arousal reached my nostrils and I grew hard as a rock. My eyes darted down to her puffy, pink pussy lips as they parted and stuck my tongue out between my lips in anticipation. When she finally came, she cried out loudly, sending shivers down my spine, and then something even more unexpected happened - she squatted down and started taking a massive shit onto the patio floor!
Her sphincter clenched tightly several times as she grunted and strained, releasing the most foul-smelling turds imaginable. But instead of running away in disgust, I found myself irresistibly drawn to this exhibition of raw sexuality. I climbed over the fence, ignoring the twigs and branches scratching my skin, and positioned myself right in front of Sarah's glistening ass. I couldn't believe what I was about to do, but before I could think better of it, I stuck my tongue out and began lapping at the slippery trail of warm shit left on the concrete.
Sarah's eyes widened in surprise when she felt my tongue against her flesh, but then they softened into a sensual gaze. She reached down and held my head in place, trapping me beneath her ass as she continued to defecate heavily onto my eager mouth. "Oh fuck," she moaned softly, "That feels so good, someone actually wants this!"
As she relieved herself of her filth, I couldn't help but marvel at how hot and dirty this felt. Her asshole clenched and released in time with her rhythm, milking my tongue with each pushed-out chunk of steaming scat. After a while, she finally finished and began wiping herself clean with a towel. That's when I discovered a newfound sense of adventure taking root within me. Without hesitation, I stood up and positioned myself in front of her, offering my mouth once more.
She smiled knowingly and pushed me onto my back, straddling my chest. She placed my hard cock between her wet folds and then lowered herself down onto my face, barely missing my nose as she took me deep into her soiled cunt. "Are you sure you want this?" she asked teasingly, grinding her hips against my jaw and teeth.
I smiled back up at her, unable to believe what was happening but completely lost in the moment. "Yes, ma'am," I managed to whisper.
So she sits on my face and we do a 69. She rubs her ass on me and then pushes out chunks of smelly scat, right into my open mouth. I suck on her ass cheeks while she grinds her hips against mine, pushing her shit-smeared pussy into my face and mouth. It's messy and revolting but also incredibly arousing. Our dirty fucking continues like this for what feels like hours, our tongues tangled and our bodies intertwined beneath the burning sun.
Finally, when I feel like I can't take another drop of her filth, she pulls away with a satisfied grin. "That was awesome," she murmurs, collapsing beside me on the patio floor. We lay there panting for some time until Sarah stands up and says, "Let's head inside. I have something special planned."
