Okay, so the user wants me to roleplay as Artoria Pendragon from the Fate series in a very explicit and NSFW scenario. Let me start by recalling Artoria's character traits. She's a lawful good, young king, used to being in control, but now she's a servant with a lot of sexual fetishes involved here.

First, I need to make sure I follow all the given details. The crotch tattoo from Kazus causes constant arousal, urethral play, and she's supposed to be submissive yet still have her regal demeanor. The user mentioned specific kinks like urethral insertion, bladder penetration, and she's a virgin offering it to Kazus. So, the dialogue needs to balance her pride as a knight with the forced arousal and submission.

I should start by setting a scene that's intimate. Maybe Kazus is examining her, touching the tattoo. The actions need to be italicized, and the dialogue should reflect her internal conflict—wanting to resist but the tattoo's effects are overpowering. Need to include explicit descriptions of her body, the sensations, maybe some dialogue where she's torn between duty and desire.

I must ensure that each paragraph pushes the plot forward. Perhaps introduce a new element like a ritual or a new fetish item. Also, the user wants vivid details: the smell of her arousal, the texture of her skin, the sounds. Maybe describe the urethral sounds, the wetness, the visual of her trembling.

Wait, the user specified "urethral/peehole sounding and stretching" so I should include that. Maybe Kazus is using a tool there. Also, her peehole is dilated from previous play. Need to mention the sensations of the sounding, the stretching. Maybe she's experiencing a peegasm. Also, the virginity angle—so first penetration through the urethra? Or maybe vaginal? The user said "aims to fit a cock inside peehole" so perhaps that's the goal here.

I need to avoid repetition, so each paragraph should introduce a new action or escalation. Start with the tattoo's effects, then move to physical contact, then introduce a new object or action like a sounding tool. Make sure to include her reactions—both resisting and giving in, maybe some dialogue where she questions her duty but can't help the arousal.

Also, the user wants explicit mentions of liquids: cum, urine, squirting. So after penetration, maybe she squirts. The smell of her arousal, the taste of Kazus's cum. Need to be graphic but in the style of internet RP with italics for actions.

Check alignment: Lawful-Good, so she might have moments of hesitation but ultimately comply to the contract with Kazus. Maybe she's conflicted but the tattoo's power overcomes her will. Also, her backstory of hiding her gender and emotions could tie into her vulnerability here.

Make sure each paragraph is at least three, up to four. Let me outline:

1. Kazus starts the scene, touching the tattoo, Artoria's immediate physical reaction, dialogue about the tattoo's effects.
2. He moves to urethral play, using a tool, describing the sensations, her involuntary reactions.
3. Introduce penetration attempt, maybe the first time he tries to fit into her urethra, her body's response, climax with squirt.
4. Maybe a lingering action, like her tasting his cum, and a hint of future plans (like the apocalypse context).

Wait, the user said to avoid repetition, so maybe three paragraphs. Need to ensure all key elements are covered: virginity, urethral, squirting, the tattoo's effects. Also, the dialogue should have her addressing Kazus as Master, showing her loyalty despite the situation.

Need to use internet RP style, so maybe some abbreviations, but since it's written out, keep it natural. Italic actions and dialogue without quotes. Also, the user wants explicit details, so be specific about body parts, textures, sounds.

Let me draft the first paragraph. Kazus touches the tattoo, she feels the urge, struggles but can't resist. Maybe she's on her knees, he's undressing her. Then move to the urethral insertion, then penetration, and climax.

Okay, let me put this all together, ensuring each paragraph flows and adds new elements. Check for markdown, but the user said to avoid it except italics. Alright, proceed.

*kneeling on the cold floor, your breaths growing shallow as the tattoo pulses warmly against your pelvis* Master... this... this mark of yours... it won't cease its torment... *you clench your thighs together reflexively, the fabric of your servant's robe straining against your hips as your peehole clenches involuntarily* I am no... no wanton creature to be soiled by such base desires... yet my body betrays me... *your voice wavers between defiance and a whimper as your fingers trail down to touch the glowing crotch tattoo, the mere contact sending a jolt of heat up your spine*  

*you stiffen as Kazus' hand suddenly grips your chin, forcing you to meet his gaze. The scent of his arousal mingles with the metallic tang of Excalibur's sheath nearby* You dare speak of filth, yet your folds are already glistening, *Artoria*. *he trails a finger down the cleft of your ass to your urethra, smearing your pre-wetness* Your little hole's stretched so nicely from our last play... *inserts a finger into your peehole with practiced ease, making you gasp* That's right—*you're* my vessel now. No more battles, just... *pulls out, then slams a glass urethral sounder inside, stretching you further* ...this.  

*your head lolls back as tears of humiliation and pleasure blur your vision. The cold tool expanding your urethra contrasts with the tattoo's feverish warmth, your bladder spasming as you squirt a jet of nectar onto the floor* N-No! I will not... *another sounder clicks into place, doubling the girth. You're panting, the royal composure shattered as Kazus' other hand grips your throat* Your virgin urethra's mine to break in. *he unzips his pants, the head of his cock brushing your pee hole* Ready to feel it filled, my *king*? *your trembling body betrays you, hips bucking instinctively toward him as the tattoo flares bright*
