The moment Silas closed the door behind him, Rias and Akeno were on him.
They didn't waste any time with words. Rias pulled him into a deep, hungry kiss while Akeno pressed herself against his back, lips trailing along his neck. Clothes were discarded in a heated rush until all three of them were naked.
Silas took control quickly.
He pushed both girls onto the massive bed, then spent the next several hours absolutely ruining them.
He fucked Rias hard in missionary while Akeno sat on her face, grinding her pussy against the redhead's tongue. Then he switched, pounding Akeno from behind while she ate Rias out.
He made them ride him together, their breasts bouncing as they took turns bouncing on his thick cock. He folded them into every position he could think of , full nelson on Akeno while Rias licked where they were joined, then pinning Rias in a mating press and filling her womb again and again.
The room was filled with obscene wet sounds, skin slapping against skin, and their broken, shameless moans.
"Silas—! Harder—!!"
"Fuck—! I'm cumming again—!!"
"Don't stop—! Fill me up—!!"
Silas didn't hold back. He came inside them repeatedly, then pulled out and painted their faces, breasts, and asses with thick ropes of cum.
He used them like personal toys, switching between their mouths, pussies, and even their asses when they begged for it.
By the third hour, both girls were a complete mess , covered in sweat, cum, and their own juices, eyes rolled back, tongues hanging out as they twitched and moaned helplessly.
By the fourth hour, they were barely conscious.
Rias came one final time with a broken scream, her body convulsing violently before she went limp, eyes glazed over, a stupidly satisfied smile on her face as she passed out cold.
Akeno lasted only a few minutes longer. After Silas fucked her through another squirting orgasm while choking her lightly, she collapsed beside Rias, twitching weakly, completely fucked senseless.
Silas finally pulled out, but still hard, looking down at the two beautiful devils he had just fucked into a coma.
In the guest Room. Xenovia and Irina hadn't slept a wink.
They lay in their separate beds, faces burning crimson, eyes wide open in the darkness as the sounds from the master bedroom carried through the walls despite the distance.
The moans. The wet slapping. The dirty words. The bed creaking violently.
Irina had her face buried in her pillow, hands clamped over her ears, but it did nothing to block the noise.
Xenovia lay completely still on her back, staring at the ceiling with a deep blush that refused to fade. Her thighs were pressed tightly together, and she was biting her lip so hard it nearly drew blood.
Every time Rias or Akeno screamed Silas's name, both girls flinched.
Irina whispered shakily, "T-They've been going at it for hours… How is that even possible…?"
Xenovia didn't answer. She simply clenched her fists under the blanket, trying and failing to ignore the heat pooling between her own legs.
The sounds only grew more intense, wet, filthy, and relentless. By the time everything finally went quiet, both church girls were breathing heavily, faces flushed, bodies uncomfortably warm.
Irina spoke again, voice small and embarrassed.
"…Silas… he's a monster."
Xenovia swallowed hard.
"…Yes. He is."
Neither of them got any sleep that night.
Silas stepped out of the master bedroom the next morning, freshly showered, looking completely refreshed. He glanced toward the guest room door with a small smirk, knowing full well the two church girls had heard everything.
'Lightweights,' he thought amusedly as he headed downstairs to make coffee.
A few hours passed. Downstairs in the dining area, Rias and Akeno were finally awake, barely.
Rias sat at the table in nothing but one of Silas's oversized shirts, hair messy, legs pressed together as she winced slightly every time she shifted.
Akeno looked equally wrecked, leaning heavily on the table with a dreamy, satisfied smile on her face, still covered in faint hickeys.
Both girls looked like they had been thoroughly destroyed… and loved every second of it.
When Irina and Xenovia eventually came downstairs still in their wrinkled church robes, the contrast was almost comical.
The two pure, holy church girls stood awkwardly at the entrance of the dining room, staring at the two well-fucked devils sitting casually at the table.
Rias gave them a tired but smug little smile.
"Sleep well?" she asked sweetly.
Akeno giggled softly. "We certainly didn't."
Irina turned beet red. Xenovia looked away, clearly uncomfortable.
Silas just sipped his coffee, completely unbothered, ' When will Kokabiel arrive again? ' he thought.
After breakfast, Irina and Xenovia left the manor promptly.
Both girls had changed back into their church robes and looked significantly more composed than they had the night before, though the faint blush that kept returning to their cheeks told a different story.
They thanked Silas one last time Irina much more enthusiastically than Xenovia and headed out to continue their mission: locating and destroying the stolen Excalibur fragments.
"Stay safe," Silas said casually as they left. "Try not to die."
Xenovia gave him a stiff nod, while Irina waved with a bright smile before they disappeared down the street.
Silas, Rias, and Akeno got dressed and headed to school together. The walk was pleasant under the morning sun, with Rias on his left arm and Akeno on his right.
Akeno leaned her head against his shoulder as they walked, her long black hair brushing his arm.
"Silas," she asked sweetly, "so when are you going to have the rest of the girls join us?"
Silas glanced down at her, then at Rias, who was also clearly listening.
"When the time comes," he replied honestly. "I'm not really in a rush."
Rias tilted her head, looking up at him.
"Why did you start with us then?"
Silas thought for a second before answering.
"Genuinely a coincidence. If it went by who I met first, I would've gone after Sona first. And I was honestly pretty close to doing that."
Both girls frowned at the same time, a small pout forming on their lips.
They had assumed they were special , that Silas had chosen them for some deeper reason. Hearing it was mostly coincidence stung a little.
Still… his blunt honesty was one of the things they loved about him.
Rias eventually sighed and leaned her head against his other shoulder.
"You really are unfair sometimes."
Akeno giggled softly. "But that's also why we like you."
They arrived at Kuoh Academy and went through the day like normal students.
Silas sat at the back of the classroom, slouched in his chair, lazily taking notes while his mind was elsewhere.
He wasn't really paying attention to the lesson instead, he was mentally chatting with Rias and Akeno through their demonic connection.
It was mostly flirting at this point.
Silas: You two are walking a little funny today.
Rias: Shut up. Whose fault is that?
Akeno: Mmm, I can still feel you inside me~
Silas: Good. I want you both thinking about last night during class.
Rias: Pervert.
Akeno: My pervert ❤️
Silas smirked to himself, occasionally scribbling something down so the teacher wouldn't bother him.
The girls kept shooting him glances from their seats, cheeks faintly pink.
The school day passed peacefully on the surface, but beneath it, the tension and excitement of their growing harem continued to build.
