Perversities of Imperishable Lust

-=Chapter 5: Ebb of the Moonlit Tide=-
The eternal house in the bamboo forest was as eerie as a dream.
Was it just a lunatic delusion that awaited the human maid?

Sakuya walked the lightless halls of the manor with the ease and confidence of familiarity. She was dressed once again in a maid’s uniform—although the neckline was a bit lower, and the hem of the skirt higher, than she recalled of her old one, and she was fairly certain her old uniform had not included a pair of lacy white thigh-highs. At least the stockings were cute, she thought as she shifted the dull silver tray she was carrying to one hand and slid open a door with the other.

“Ah, hello, Sakuya,” Eirin greeted the maid with a smile. “Put the tray down and come over here, please.”
“Yes, my lady.” Sakuya still felt a little strange addressing the Lunarian that way, but followed her orders anyway.
“Well, it’s been just about two weeks that you’ve been serving me,” Eirin said as she placed a hand on Sakuya’s thigh. “How have you been liking it so far?”
“I suppose I can’t complain. I’ve been treated quite well.”
“Better than Remilia treated you?”
Sakuya went silent.
“Don’t answer that; I’m sorry I asked. You have been an excellent servant...” Eirin’s smile broadened just a little as her hand slid slightly toward the other girl’s crotch. “...in all respects. Thus I feel I can trust you enough for a little... experiment I’ve been looking forward to for a while.”
“Experiment?”

“Are you sure you’re okay with this?” Sakuya asked, pulling the ropes taut and tying them off.
“Absolutely,” responded a nude and bound Eirin. She tugged slightly at the ropes lashing together her wrists and pinning her arms to her back, making sure they were tightened to her satisfaction. “All this time, I’ve been the one dominating you, and I must admit I’ve gotten a little curious regarding how that must feel for you.”
“I see... so what now?”
“That’s for you to decide. You’re a creative young woman, aren’t you?”
Sakuya honestly didn’t know the answer to Eirin’s question, but decided it didn’t really matter. Her heart drummed out a marching tempo as she leaned in and gave the Lunarian’s chest her full attention. The two cream-complexioned breasts, unusually large yet perfectly balanced nonetheless, had been an object of curiosity and almost-fascination for Sakuya almost since she had come to live at Eientei.
“Impressive, aren’t they?” Eirin asked, sticking out her chest a little to give the maid a better look. “I know you’ve been wanting to see these for a while.”
“I have... how did you know?”
“You don’t live 1,200 years without learning a few things about people, Sakuya dear.” Eirin smiled. “But these aren’t museum artifacts. Go ahead and touch if you like.”
Sakuya eagerly assented, taking Eirin’s breasts in her hands and a cherry-blossom-pink nipple in her mouth. She teased it with her tongue until she felt it grow stiff, and as Eirin’s sighs of pleasure fell upon her ears, her excitement grew.
Eventually Sakuya lifted her head, a thin string of saliva stretching momentarily between her lips and Eirin’s nipple.
“Why’d you stop?” the Lunarian asked between heavy breaths, only to relapse into elated moans as Sakuya began to work on her other nipple. As she did, her hand crept between Eirin’s legs.
Eirin’s moans and heartbeats came faster and faster as Sakuya’s lithe fingers eased into her vagina, probing gently and teasing at her G-spot. As the Lunarian cried out, Sakuya felt several squeezes on her fingers as warm fluid ran down them and pooled in her palm.
Eirin lay back on her futon, gasping for air, her face and breasts still flushed rosy red. “You... are quite the specimen, Sakuya...”

Sakuya had returned to where she had left the tray, and was lifting up the burnished teapot resting upon it when Eirin stopped her, “Leave the tea. We’re not done yet.”
The maid walked back over to the futon. “We aren’t?”
“Of course not.” Eirin got to her knees. “After all, you haven’t reached orgasm yet. Now, please lift your skirt.”
“Y-yes, mistress.” A light blush crossed Sakuya’s fair face as she raised the lacy hem of her skirt so her panties, a light pink pair adorned with a cute red bow, were in full view.
Eirin leaned in and, gripping Sakuya’s panties with her teeth, pulled them slowly down until the maid’s vagina was exposed to her warm breath. Then she began to lick.
“Mmmmm... oh, Eirin...” Sakuya was entranced by Eirin’s deft tongue, barely retaining enough concentration to keep her skirt up. Her moans became louder and more rapid as the Lunarian began work on her clitoris, gently suckling and rhythmically licking.
Sakuya’s lusty cry echoed through the manor halls and her toes curled inside her high heels as she climaxed. Eirin licked up every rivulet of vaginal fluid that started down the girl's thighs, and looked up at her with a smile.

Elsewhere, a girl with her hands tied slammed into the ground with a whimper and bounced a little. She was pretty, with a blue dress and hat and long, silver, blue-streaked hair; her ample chest heaved as she looked fearfully up at her short, bat-winged, pink-clad tormentor.
“Had enough, Keine?” Remilia asked with a smirk.
“I’m telling you, I don’t know who abducted your maid! Please, stop it!” Keine was on the verge of tears.
“Oh, there’s something the bookworm doesn’t know? Maybe this will jog your memory!” Remilia seized the bound girl’s lapels and tore her dress open; her breasts jiggled as they were abruptly freed.
“Wha—“ was all Keine could get out before her captor grabbed her nipples and twisted hard.
Remilia savored her prisoner’s scream. “How do you like that?”
“I... I can’t tell you what I d-don’t know...” Keine choked out between sobs.
“So make an educated guess.” Remilia’s fingers remained tightly on Keine’s nipples.
“Well... it’s j-just a rumor, but... I’ve heard she’s in that mansion in the... in the bamboo forest...”
“See, was that so hard?” Remilia let go. “But if I find out you’re lying... well, there’s a wooden horse back at the Scarlet Devil Mansion with your name on it.”
Keine shuddered as Remilia flew off.
