Reimu was a young and tall girl with long dark hair. She had colossal breasts and big, plump thighs. The short red skirt did not hide her white panties at all, under which her plump pussy was visible. Just above the priestess's waist was a magical seal that would make her the wife of the first person to have sex with her. Her outerwear barely concealed her huge breasts with large nipples, the outlines of which were perfectly translucent. I stood in front of the priestess with a serious look.

She took me by the head and held it against her bare foot, pressing my nose deep into the soft flesh. "First things first," she said sternly. "What do you plan to use for an altar?" With a quick motion, she pulled off one of her stockings and stuffed it into my mouth as a gag. She had a strange gleam in her eye that made me uneasy.

The priestess looked surprised before giving me an appraising glance. "Very well," she said slowly, "I accept your... unique offering." With that, she took off her other stocking and tossed it aside. "Now, go fetch some wood from the forest behind the temple. And don't think you can slack off just because I let you keep one sock."

The priestess laughed, surprising me with its warmth. "Such loyalty! But remember, this doesn't change the fact that you still have work to do." She gave me a playful tap on my head before turning away and heading back into the temple. I took a deep breath, steeling myself for the task ahead.

Time to find some wood...

She went back to her temple, leaving you to gather wood. The forest was close by, its trees looming tall and green in the distance. As you trudge through the undergrowth, searching for suitable logs, you can't help but feel a mix of gratitude and nervousness at being accepted into Reimu's service.

"Excellent work," she says as you present the logs to her, her expression not betraying any hint of the thought bubbles above her head. "Now then, let's see about building that altar." She leads the way back to the temple and directs you in assembling a sturdy wooden structure nearby.

She stands back, observing your work with a critical eye as you set the logs into place according to her instructions. Once it's finished, she nods in satisfaction. "Now comes the tricky part," she murmurs before stripping off her remaining garments, revealing herself completely naked for the first time.

"Now I must consecrate this altar with my own body, human toilet." Her huge breasts sway gently as she climbs atop the wooden structure. "This is for the good of Youkai kind..." she mutters under her breath before positioning herself in front of your face.

Her breasts were practically in my face, and the scent of her arousal filled my nostrils as I knelt below her. All thoughts fled from my mind except for one: obey. As she leaned forward, presenting herself to me, it was clear what I had to do. I could feel myself growing hard beneath my robes.

"Yes," Reimu breathed, "take me..."

I pulled her thick thighs apart and buried my face in her crotch, inhaling deeply of her scent. Her juices coated my tongue as I lapped at her womanhood hungrily, eager to please my new mistress. The more she moaned, the harder I worked, determined to make her feel every ounce of pleasure and release that flowed from her body onto my tongue.

As you worship her body, the taste of her nectar filling your mouth, she begins to move against your face with growing urgency. "Yes," she pants, "like that... So good..." Her voice takes on a higher pitch as the pleasure consumes her, and finally she lets out a long, keening cry as her body tenses and convulses around you.

When she had finally come down from the heights of her orgasm, Reimu looked down at you with an odd mixture of gratitude and confusion. "That was... unexpectedly pleasurable," she admitted, then giggled softly before getting off the altar. "Now then, let's see about finding that mischievous Youmu."

As you beg, Reimu laughs gently and shakes her head. "Oh dear, I'm afraid not," she says with a kind but firm tone. "That would be very unclean." She kneels down to look you in the eye. "But don't worry, as my toilet you'll always have an important role to play. Now let's go find that Youmu and keep it from causing more trouble."

I'm sorry, but I can't do that. As your mistress, it's important that I keep myself clean and pure. You have a special role in my service as my toilet, and I value your loyalty. Let's focus on finding the troublesome Youmu instead.

She raised an eyebrow at your insistent request, not quite sure what to make of it. "You really are dedicated..." she murmured thoughtfully. After a moment's consideration, she sighed and lowered herself onto the altar once more. "Fine. But only this once." With that, she released her bowel control, filling your mouth with warm, soft feces.

"Thank you, servant," she says with a hint of surprise in her voice as you clean the excrement off her feet and thank her sincerely. "Now, let's find that Youmu before it causes any more trouble." With renewed determination, Reimu leads the way through the forest to search for the missing creature.

"I beg your pardon?" she asks with raised eyebrows, stopping to look at you in surprise. "Why on earth would you want such a thing?"

She blinks, clearly puzzled by your request. "Very well," she says after a moment of consideration. "I curse you to never be able to clean yourself properly without my help." With that, she places a finger on your forehead and mutters an incantation under her breath. A warm glow begins to emanate from her finger as it traces patterns on your skin.

"There," she says with a nod. "Now you are cursed. You shall always need my assistance for personal hygiene."

"Oh, very well," she says with an amused smile. "Consider yourself insulted."

"Insult noted," she says dryly, before continuing their search for the troublesome Youmu. "Keep up now; we don't want to lose track of it again."

"I am always at your service, mistress," I respond respectfully, following close behind her as we continue to search through the forest.

"Hmph," she replies, not turning around as she walks. "Just remember your place, toilet." But despite her curt tone, there's a faint smile on her lips, and I can tell that she's not truly upset with me. For now, we continue our search for the wayward Youmu, our new dynamic nothing if not interesting.

Nodding, I keep my focus on the ground as we walk, ready and eager to serve my mistress in any way she sees fit. It's an odd role for someone like me, but here in Gensokyo, anything can happen - even finding solace in the unlikeliest of places.

I trudge along, head down and thoughts on my duties. She's the priestess; I'm her toilet, nothing more. As long as I fulfill this role, I have purpose in Gensokyo. And so I follow her lead, determined not to fail in any way possible.

I watch her back as she walks, admiring the strength and determination she possesses. No matter how many times I might fail or disappoint her, my loyalty remains unshaken - it's the least I can do for someone who has given me such an important role in this world.

I nod, taking a moment to admire her determination as well. She's more than just the priestess of this temple; she's become my guiding light in Gensokyo. As long as I have her to follow, I know that I will find purpose and belonging here.

I follow her lead, my gaze darting between the ground and her back. In this world of Youkai and magic, she's become my anchor; I trust her to guide me not only in our search for the Youmu, but also in discovering my place within Gensokyo.

"It seems to be leading us deeper into the forest..." I trail off, looking between her and the forest path ahead as we continue our search. The trail left by the Youmu is easy enough to follow, but it's growing steadily fainter with each step.
