Medea, the Witch of Betrayal who was summoned as Servant Caster in the Fourth Fuyuki Holy Grail War, felt exasperated. She wanted to think her "Master's" explanation in peace, yet his handsy touch was extremely distracting.
A while had passed by since she was summoned. Now her Master was sitting on a sofa while she was sitting on his laps. He had his left hand on her left breast hidden by her silky robe, kneading and squeezing it while playing her nipple. His other hand was kneading and rubbing her thighs after he pulled up the lower part of her robe. He was kissing her nape and neck, trailing his hot and soft lips on her skin.
The sensation was pleasant indeed. But, it distracted her. Damn her sensitive body despite it is constructed from magic energy!
She wanted to tell him off, so she could think in peace. Alas, she couldn't do so. One of her skill, Ephemeral Romance, made her feel infatuation with him. It was similar to her infatuation to Jason when she lived at the Age of Gods. The only reason she never acted like a hopeless, lovestruck woman in front of him was her pragmatic mindset, her unpleasant experience, and her acting skill.
Medea decided to hypnotize herself and split her attention between reveling in his ministration and concentrating on her thoughts. Her Master had told her that he was summoned as the Servant Caster before her, killed the serial murder who summoned him, and then summoned her. He told her that he came from "Outside". In other words, he came from a different universe. When she asked why Counter Force hadn't tried to erase him, he gave him an answer with a cocky smirk.
In short, he had a power to be a neutral guest of all universes he visited. As long as he did not do something that would alarm Counter Force, such as planning to erase all humanity in the planet or destroyed the planet, Counter Force would let him do as he pleased.
'And his power… it's ridiculous. He is already at the level of True Magician with their ridiculous true magic and Gods with their Divine Authority,' Medea mused, feeling both excitation and a bit trepidation because of his power.
He had promised to incarnate her and give her a new live if she accepts to be his woman. Medea realized that her Master was powerful, but he was also a vain, lustful, and foolish man.
He reminded her too much of Jason, and a sane part of her mind who had yet to be affected by her curse, told her that he would betray her like what Jason did to her. But his promise for a new life and opportunity to ascend into godhood is too tempting. With her experience and observant nature, she could see when someone is being honest or not. And so far, he had been truthful with her.
She only needed to spread her legs and become a perfect, obedient wife for him. A cheap price to reach the level beyond her divine tormentors when she was alive. Her only problem was his foolish desire to have a harem, and she couldn't see herself accepting it.
Although Medea had stooped low in her old life, she still had her pride. She couldn't easily accept to be one of many women of his. If he wanted her to be his woman, he must only have her.
"M-Master, hn!" Medea called him, yet she wanted to curse him because she made her stutter and release such a lewd, shameful voice.
"Yes?" He asked, and Medea felt relieved when he stopped his touch.
"Do you need to create a harem?" She asked after turning around to face him. At this point, she had taken off her veil.
When she took off her veil, she felt pride and flattered by her Master's lustful, wanting gaze on her. It made feel appreciated as a woman, though she also felt a bit disgusted and mildly unimpressed because he was just another perverted man she had met and used after she burned Jason and was known as the Evil Witch across the Greece.
Putting aside his unpleasant personality that reminded her too much of Jason, his main selling points were his exotic and handsome appearance and his ridiculous power. Certainly, he could become a dependable protector if she could control him.
"Of course, it's my ultimate dream! I always want to become a harem king but never had the chance! Now, I have my powers, I can fulfill my wish and fantasy!"
Maintaining her seductive smile, while inwardly rolling her eyes at the simpleton, Medea asked him, "Am I alone not enough? Am I not attractive enough?"
"Oh, honey, you are the most beautiful woman I have seen in my life! I want you to become my woman. But! I don't think that you alone can satisfy me! I fear you won't match my stamina alone!"
Although Medea felt offended by his declaration, she maintained her alluring smile easily. Inwardly, she was planning how to control this overpowered idiot using the stick and carrot method.
"Really, now? Be careful with what you speak, dear~ I'm confident that I can match you in bed~"
"Bwahahahaha!"
Medea's smile lost its seductiveness and became cold. She was really offended by his boisterous mocking laugh. When he calmed down, she immediately spoke up.
"Why were you laughing? Did you think my words funny?"
"Of course, it is funny. You may have the experience, sweety, but I'm sure that you don't have a power to endlessly and instantly regenerate your consumed mental strength and stamina. I have, honey. It allows me to fuck your ravishing body nonstop until I lose interest in fucking for a short while. A day? It is short. A full week? Easy. The whole month? I would stop midway because of boredom. Only fucking for a whole month will be boring. You may a heroic spirit, but don't have endless mental fortitude, right?"
Medea dropped her smile and watched his cocky expression intently. When she tried to find a sign of lie or empty boast in his eyes, she only found truth and absolute confidence.
Suddenly, Medea felt unsure. She tried to imagine her being fucked silly nonstop for a week and felt chill on her spine. She might be a heroic spirit with wealth of experience and strong mental fortitude, but her mental strength would get drained in sex and she would meet her limit after fucking for hours. She had no confidence to indulge him in sex for seven days and seven nights nonstop.
"Well, if you're afraid to be betrayed like in your legend, don't worry! I swear that I won't betray you. Although I will have many women in future, you, as my first, will always have a special part in my heart. You can even become the alpha in the pack, so to speak. So, what do you think?"
Medea became thoughtful. Surprisingly, her ridiculously overpowered and perverted Master allowed her to think in peace.
After a while, Medea gave her answer and…
