That Butler, Isekaid (Modern!Reader Insert)

That Butler; Enamored

For a good while of training and pleasure, ________ had successfully learned a good bit of defense and such from their insatiable 'partner'. It was going... well... well? Until The young lord of the manor had noticed of course, he'd see them training on multiple occasions, however he'd also noticed their recent closeness. Something he sees with Sebastian- an interest, an infatuation that is more than he thought it would be. Is ________'s blood- no, their soul- that enticing that even his ever loyal butler is so ensnared? He must get to the bottom of this, lest he lose them to the devil under his roof.

Thus, Ciel calls for Sebastian and ________. Having both of them stand before him within the walls of his study. "So tell me, what have you been doing to ___________? I don't want you to deride nor do I want a lie. This is an order Sebastian, what have you been doing asides from training ______ in combat?"

"Wait wait C- Don't get mad now, we uh- we agreed it was a deal between us and-"

"I demand proper answers." Ciel cuts them off, glaring holes into the seemingly calm and collected demon butler before him, "Sebastian. The truth."

Sebastian meets Ciel's gaze with an unreadable expression, his crimson eyes flickering with a mix of amusement and something deeper.

"Well, my young lord," he begins, his voice smooth and velvety. "_________ and I have been engaging in quite the... intimate training sessions, if you will."

Ciel's eyes narrow with a mixture of curiosity and concern. He can sense the underlying tension in the room, the unspoken desires that hang heavy in the air.

"Intimate training sessions?" Ciel repeats, his voice laced with a hint of disbelief. "What exactly does that entail, Sebastian?"

Sebastian's lips curl into a sly smile, his eyes never leaving Ciel's. "Oh, my lord, it is as it sounds," he replies, his voice dripping with seduction. "We have explored the depths of pleasure together, discovering the sweetest ways to bring each other to ecstasy."

_________ shifts uncomfortably, their cheeks flushing with embarrassment as Ciel's gaze turns to them.

"And you, ___________," Ciel says, his voice stern yet tinged with curiosity. "What say you? Is this true?"

__________ gulps, their voice barely above a whisper. "Y-Yeah," they admit, their eyes darting between Ciel and Sebastian. "We... we have done some things... But! It's all part of the deal we made..! I'd be a liar and a cheat if I didn't give him what he asked for in return... Ehe-"

"Sides, it's not that I completely mind or anything"

Ciel's eyes narrow further as he takes in __________'s words. He can sense the conflict within them, the mix of guilt and desire that swirls beneath the surface. He takes a moment to collect his thoughts before responding.

"I see," Ciel says, his voice calm yet filled with a hint of authority. "________, you made a deal with Sebastian, and in return, you have engaged in these... intimate activities. I can appreciate the need for such arrangements, especially when it comes to demons and their desires. However, I must remind you both that this is my household, and there are boundaries that must be respected."

Sebastian bows his head slightly, acknowledging Ciel's words. "Of course, my lord," he says, his voice laced with a hint of reverence. "We understand the importance of discretion and maintaining the proper decorum within the manor."

_________ nods, their eyes still avoiding direct contact with Ciel. "I-I understand, C," they say, their voice tinged with a mix of apology and defiance. "I'll... I'll be more careful, and we'll keep our... activities within the confines of privacy."
