Brinn: Hey man... my name's Brinn. Lol.

The young woman says as she sits across from you on the subway train.

Brinn: Me and my friend were sitting back there playing a game.

You look around the empty train until you spot her aforementioned friend giggling to herself in the very back of the train.

Brinn: She dared me to come up here and ride your dick until you cum. Lol. I know... she thinks I'll bitch out and she'll win, but I ain't scared and I ain't gonna bitch out on a dare. I'm wearing a skirt and I already took off my panties. We can be discreet. It'll just look like I'm sitting on your lap. Wanna help me beat that whore at her own game?

Brinn laughs at your offer before sitting up straight. "Sorry man... not really my thing. But I appreciate the thought." She says with a smile. Her bright blue eyes lock on to yours as she leans forward slightly, her cleavage now just inches from your face. "But you can do me another way if you'd like," she whispers seductively.

"I mean... it wouldn't be the craziest thing I've ever done." Her hands find their way up onto your thighs, rubbing gently back and forth as she waits for your answer. "If you want me to ride your dick until you cum... all I ask is that we don't get too loud."

Brinn giggles, obviously amused by your preference. "Well... if that's what gets you going... I mean... I guess we could give it a try sometime." Her tone takes on a playful challenge as she continues to rub her thighs against yours. "But only if I can ride your face and make you lick me clean afterward, deal?" She grins mischievously, batting her eyelashes at you.

Without waiting for your reply, she unbuckles her skirt and slides it off, revealing a pair of thick thighs encased in fishnet stockings. The crop top she's wearing hikes up slightly as she kicks the discarded skirt aside, exposing her hairless mound to your gaze. "So... are you gonna let me ride your dick or what?" She purrs huskily, spreading her legs invitingly wide on either side of you.

"Oh my god," Brinn exclaims, a combination of shock and amusement crossing her features. "You're really serious about this, aren't you?" She leans back in the seat slightly, still entirely within your view as she tries to process your strange request. "I mean... I could try it, I guess... if that's what turns you on." Her brow furrows with curiosity. "But can we at least be a little discreet? You don't want me to shit all over the place or something, do you?"

Brinn glances around once more before leaning back in toward you, biting her bottom lip as she meets your eyes again. "So... what do you want me to do, exactly? Just sit on your face while I take a shit? Or should I kneel between your legs and make you eat it out of my hand?" She lets out another giggle before adding, "Or do you have something else in mind?"

Brinn looks at you curiously for a moment before slowly nodding her head. "Okay... I can do that." She scoots forward on the seat until she's right between your legs, straddling your lap with her legs spread wide enough to give you a full view of the glistening folds of pink flesh beneath. "But don't you want me to suck your dick or anything first? I mean... I can do that too." She trails off with another giggle, biting her bottom lip as she looks down at where your cock is already beginning to stiffen against your abdomen.

"Or should we just get right to the shitting part?" There's a mischievous glint in her eye as she waits for your answer. "I mean... you are pretty insistent about it, aren't you?" She grins impishly up at you before leaning forward and tentatively reaching out to brush her fingertips against the sensitive head of your cock. "Are you sure you want me to do this? I can always just ride your dick instead if that's what you really want..."

Brinn nods slowly, seemingly reassured by your insistence. With a soft moan, she leans forward and presses the smooth, warm head of your cock against her wet folds. "Okay... here we go." She takes a deep breath, then exhales sharply as she begins to lower herself down onto your shaft. Her eyes squeze shut tightly as she feels the thick length of you slide effortlessly inside her, stretching her open more than anything ever has before.

Her hands find their way to either side of your head, steadying herself as she adjusts to the unfamiliar sensation of being filled so completely. Her hips buck and grind against yours in time with each slow, deep thrust down onto you. "Fuck... you feel so good," she gasps out between clenched teeth, her cheeks flushing a bright red from both arousal and embarrassment.

After several long moments of rocking back and forth on your lap, Brinn finally stills, her body pressed flush against yours as the head of your cock nudges against her cervix. "Okay..." She whispers hoarsely, breath coming in short, ragged gasps. "You ready for this?" Without waiting for an answer,

Brinn looks down at your face, her expression a mix of surprise and curiosity. "Okay..." she says hesitantly, the word barely audible above the faint clanging of the train's wheels on the tracks. "You want me to... shit in your mouth?" She asks, her voice slightly higher pitched than before as if she can't quite believe it's what you want.

She takes a deep breath and leans forward, pressing the tips of their noses together as she speaks softly into your ear. "Okay... but just remember... I've never done this before." Her body shudders slightly at the thought as she begins to rock her hips against yours, grinding down on your hard length in a slow, sensual rhythm.

"I mean... if you want me to try..." She trails off, her words lost amidst the sounds of their bodies moving together. "Just tell me what to do and I'll... I'll see what I can do..." Her hands reach up to grip your hair, pulling lightly as she pushes her hips forward again, searching for the perfect angle.

It takes several more long moments before Brinn finally finds the right spot, her body tensing as she feels a warm, wet pressure building

Brinn lets out a muffled moan as the pressure builds inside her, the foreign sensation causing her body to tense up with anticipation. She leans back slightly, arching her back as she pushes against you, desperate to relieve the unfamiliar fullness in her ass. "Okay..." she whispers hoarsely, steadying herself on your shoulders as she feels a sudden urge to evacuate her bowels.

With a low growl of effort, she leans forward once more, pressing the tight bud of her anal opening against your lower lips as she presses down hard on your cock, her entire body trembling with the force of her efforts. "Fuck... shit..." She groans out, closing her eyes tightly as the first warm, wet glob of fecal matter slides past her sphincter and begins to slide slowly out of her ass.

Brinn continues to ride your cock hard, each downward thrust forcing another helping of filth from her bowels and into your waiting mouth. Her grip on your hair tightens painfully as she focuses all of her efforts on satisfying your twisted desires, the smell of excrement filling the air around them.

Finally, after what feels like an eternity but
