Chapter 53 - Side Story: The Full Moon and the Vow
I decided to make this a side story.
※ Mild R15 (reading this is not necessary to understand the main story)
By the lakeside, they shed their clothes and washed themselves while standing back to back.
"When we come next time, let's visit the grave."
"Mm."
"Since I haven't reported that you have officially become my older sister-in-law."
"...Yes, I must tell her properly."
That was the extent of their conversation.
Upon returning to the castle, Elenoa was led by him to the top floor of a tall tower. This tower was separate from Elenoa's private room and residence. Even so, it was sufficiently high.
The circular space resembled a mysterious ruin.
The materials of the walls and pillars seemed different from the rest, with parts chipped away here and there. Pillars of what Elenoa would call the Corinthian order in her previous life supported the heavy-looking ceiling while being entwined with vines. Through the gaps, one could see the sky, black as spilled ink, and a river of stars. And there, stuck flatly against the sky, was a pale blue full moon.
There were no walls to speak of.
Most characteristic of all were the thin grooves running across the floor and the water flowing within them. Elenoa could not even imagine where the water of this artificial river was drawn from, or how it was transported to such a height.
The deep, wide river in the center formed a large circle, and that circle looked like a pedestal for a sacrifice. A magic circle utilizing the entire ring had already been drawn in deep black.
When she placed her bare feet on the floor, a cold, hard sensation was transmitted to her.
The two advanced with soft footsteps, stopping their feet just before crossing the boundary of the circle. To Elenoa, who had grown stiff with tension, Louis urged her apologetically.
"Elie, it is about time."
"...Mm. ...Turn around."
"Certainly. Please use this. It is something I used in the past."
"Mm."
Elenoa let her white one-piece dress fall, and draped a black robe over her naked skin to hide her body. She advanced to the center of the circle and sat down heavily on the cold floor.
As Louis's footsteps approached from behind, Elenoa's heartbeat finally became tremendous.
"Pardon me, from behind."
Upon being told this, Elenoa lowered the robe from her shoulders. Clutching the only garment to her chest, she tried to defend her front at all costs.
Her long hair was lightly gathered and flowed over her right shoulder, and she was touched on her exposed back. She was ashamed of her shoulders, which jumped at the mere touch.
"If you are this tense, it will be difficult from here on out, you know?"
"Uu..."
Soothed by her gentle husband's voice, Elenoa groaned.
Seeing her appearance, which seemed to say she could not take it anymore, Louis deliberately brought his lips close to her ear.
—You need only leave your body to me.
It was a voice so faint it seemed to dissolve into the night air, yet undeniably sweet.
On Elenoa's back, centered along her spine, layered patterns were drawn.
The blood mixed into the ink used was, as expected, his.
The circle, and the ancient language used in sorcery. This contract ritual, which he seemed to have been contemplating for some time, contained binding power over her and several other effects.
As time passed, Elenoa began to notice changes in her body.
When his fingers slid across her skin, her body felt hot. When he touched the base of her wings, her waist jerked violently.
"Nn... uh."
"...It seems to feel good."
"............"
"Will you not deny it?"
"...!"
"If there is no pain, then I think that is fine. You look very delicious right now. So much so that even this time spent like this feels frustrating."
"E-eat, me?"
"Please do not be seriously afraid. If you make such a face, I will be able to endure it even less."
"But, eating a fairy is no laughing matter."
"...I will not use you for medicine or the like, so please try to forget that matter as much as possible."
Yes, the back is finished.
Upon being told this, she finally cowered, half in tears.
"W-wait, a moment."
"What are you hesitating for? It is not as if this is your first time."
"It is my first time... for me..."
Elenoa, flustered and ashamed to show the skin usually hidden by clothes, was deprived of her freedom. Her hands and feet were inflicted with [Status Ailment: Paralysis], and the robe, her last line of defense, was gently brushed away.
When she was put in a position as if hugging her knees, she felt so embarrassed she wanted to die. If she moved, her two swellings would shake, asserting her femininity with all their might. Feeling terrible shame and impatience at being unable to hide her embarrassing parts, she tried to beg, "Don't look," but he answered with a smile, "It is beautiful," a non-answer.
With the form of the contract ritual taking priority, she did not know what trajectory his fingers would trace, nor was her will reflected. Each time ink was drawn on her embarrassing parts, she shook her head in refusal. Sometimes twitching and crying in shame, she leaked delicate voices.
And so, fine lines were layered over her front, the insides of her thighs, from her arms to the backs of her hands, all over her body.
Finally.
Some pattern was drawn on her forehead, and
"'With my magic as the wedge, the wedding candles and the vow.'"
Along with such a chant, a kiss was placed there.
"'Freedom'" — this was on her back.
"'Subservience'" — this was on the nape of her neck.
"'Restraint'" — this was on her collarbone.
"'Obedience'" — this was on her chest.
"'Sincerity'" — this was on the back of her right hand.
"'Independence'" — this was on the back of her left hand.
"'Concealment'" — this was on her lower abdomen.
"'Chastity'" — this was on her inner right thigh.
It seemed that the corresponding language was drawn for each.
The ancient language whispered sweetly each time she was kissed on her body remained, as ever, unintelligible. Yet each word made some part of her body throb.
The drawn magic formula began to glow, sporadically and gradually.
"'Do you swear?'"
"...Yes."
Perhaps Louis's magic was seeping in, for she understood his ancient language now.
"I am glad. If you wish to remain by my side like this, please hold my hand."
Louis extended his hand. When Elenoa timidly intertwined her fingers with his, he suddenly gripped it strongly.
"With this, half is established."
Upon saying so, the patterns all over her body disappeared as if soaking into her skin.
Elenoa, who let out a breath of relief, had the robe that had slipped down draped over her.
Having forgotten what would happen after this, she was under the complete impression that it was all over.
Therefore, when she was gently pushed face down, she turned to look at Louis with a confused expression while supporting herself on the floor.
"...What?"
"The post-ritual must also be performed here. If we leave the magic circle, everything until now will be wasted."
"Ah, ...h-here? But outside..."
"No one will come. Your wings will get scratched if they rub against the floor, so this time, pardon me from behind."
While saying this, Louis took off one of his jackets. He loosened the tie of the shirt he was wearing underneath and covered her. He stroked her wings, which were tense with nervousness, as if to calm them.
Come to think of it, I remembered this game had an eighteen-rated version.
＊
The 'legitimate contract method,' accompanied by the transfer of a vast amount of magic power — though trivial for Louis — gave Elenoa excessive pleasure during the post-ritual, just as it had when she was being smeared with ink during the pre-ritual.
Her waist was pulled in as she tried to escape, forced to cry out flattering voices continuously while prone, and she sobbed at the unfamiliar pain while clinging to the robe spread on the floor, her breath coming in gasps.
When wind blew in through the pillars, she became aware that this was a semi-outdoor space and wanted to die again. She lost consciousness once, and when she next opened her eyes, she was pushed onto his bed on her back and embraced again. It was an uncharacteristically uncomposed expression, as if he were about to spit out all the passion he had suppressed until now.
About thirty minutes passed since then.
Elenoa sank her body into the large bed and glared at Louis, who looked happy all by himself beside her.
"...Terrible."
"Pardon?"
"This, terrible, why, I, I, like that...!"
"They say that the transfer of magic power is accompanied by pleasure for the receiver, and especially with a partner of your race... was it not akin to giving you an aphrodisiac?"
"Calmly! Do not analyze! The me from just now was not me, so, please, forget it!"
"In the first place, ever since long ago, you have made that kind of face every time you drank my blood."
"That cannot be true."
"Unconscious behavior is frightening, isn't it?"
You must be tired, so go to sleep. When urged like a guardian, Elenoa, who had taken the place of a parent, found it unpleasant. However, the hand of 'Husband' and 'Master' Louis, who stroked her head, was the best sleep aid for a tamed fairy.
—Come to think of it, I wonder if humans and fairies can have children. I am a little worried. Having Demon Lord-sama as a father would not be good educationally.
When she asked Louis this, the answer came back lightly.
"They can, when they can."
"Is that so?"
"The number is not large, but several half-humans, half-fairies have been confirmed. It is an act of making children, after all, so it is natural."
"The predecessors did something quite reckless. To take such a risk with just one contract, though it is not something to say after the fact."
"...It would not be troubling if one were made, would it?"
"Well, no."
"At this rate, we might as well continue until one is made."
"Nn?"
"If I pour a lot in here, fill you with me, and a child is made..."
Inside the bedding, a hand was placed on Elenoa's abdomen.
"You will definitely be unable to leave me, won't you?"
