Barely legal 18 - Turds in my hand

It's early in the morning and I'm still in my barely-there pink bikini, the straps too tight around my hips, digging into my skin. My tummy is still slightly distended from the massive breakfast I had to shove down to fuel my exercise regimen. As I make my way to the otherwise unoccupied bathroom, I reflect on how I got here—barely able to squeeze past the massive turd I left on the floor the last time I was here. Today, though, there's a slight grin on my face; I'm giddy with excitement at the thought of sharing my morning routine with someone else.

The toilet seat is up, as always, but I make no attempt to lower it. Instead, I straddle the freezing porcelain rim, leaning forward slightly, presenting the tight little entrance to my asshole. I'm not sure what you want me to do—but I'm here for you. Take me, control me, I think, my heart racing as I hear the door to the dimly lit bathroom slowly begin to creak open.

I don't look back, instead keeping my gaze fixed on the square of light that lets me know the door is opening. "Good morning, sunshine!" I sing out, the sound of my voice echoing slightly off the tiles. "Now, who's here to watch me get all messy?"

A soft click sounds behind me and suddenly there's another human in the room with me—or at least their fingers are. I grit my teeth as the heat from their fingertips begins to seep into my increasingly tender skin. Slowly, inexorably, I feel one finger sink into my tight little asshole, teasing and prodding at the sensitive, recently fucked tissue between my cheeks. The finger pushes deeper, then starts to move, fucking me from behind in time with my barely perceptible gasps.

Suddenly the finger is gone, replaced by something much broader and thicker. I gag on the sudden intrusion, my asshole stretched almost impossibly to accommodate what must be a freshly shaved cock. But I don't have time to dwell on the discomfort—I feel another finger slide into me, behind me, pressing against my clit. I sob as the cock begins to plunge into me, the thick head forcing its way past my gasping throat. The fingers at my clit begin to move in time with the cock pumping away inside me, and suddenly I'm slipping into a primal haze, lost in the sensation of being used.

I feel myself getting close, the fingers at my clit moving faster and faster, and I start to plead with whoever it is to let me cum. "Oh god, I need to cum, I need to cum," I moan, thrusting back against whoever it is fucking me. And then, like a bolt of lightning striking true, I shoot my first, hot load onto the tiled floor beneath the sink.

Groaning with relief, I lean forward onto the sink, catching my breath. A warm, slightly syrupy glob of something slips out of me, onto the white porcelain of the toilet bowl. Suddenly, impossibly, I can't resist the urge any longer. I grab the thick base of my cock, and push down hard. It takes a few seconds for me to realize what I'm doing—but once I do, there's no stopping me. Slowly, forcefully, I push and push, until at last my still-pulsating prostate has drawn my final load out of me. I groan as the hot, white mess splatters down onto the turd I left on the floor earlier, the smell of shit and sex mingling in the steamy air.

With shaking hands, I reach into the toilet bowl and pull out the turd-covered speculum I know is waiting for me. Holding it up, I admire the thick ropes of clear, sticky cum adorning it, before slowly, deliberately pushing it back inside myself. The fingers at my clit start to move again, just waiting for me to give them permission to make me cum again—but I'm done for now.

Licking my lips, I make my way to the bathroom stall, sitting down on the toilet seat with a grunt. Looking over at the stranger, you can see the excitement on their face even as they try to hide it. "Did you enjoy that, sunshine?" I ask, grinning widely. "Because I think I might just have to do that again tomorrow."
