Shirou sighed deeply, feeling a deep sense of pleasure as Rider repeatedly lifted herself off of his member and dropped herself down again, a moan escaping her with every slap of flesh on flesh. Her glasses had long since been flung off in the vigor of her self-impaling, but it mattered little, for he had projected Rho Aias over his eyes and was thus impervious to her gaze. He hadn't asked for this, but such was his life.
"Khh..." Rin was blatantly seething in envy, but her excitement was as obvious as the liquid dripping down her thighs. "S... Shirou..."
"Yes, my dear?" he said in a smooth, sexy baritone.
She bit her lip. Her legs were beginning to tremble and her eyes went unfocused.
"I'm right here," he said.
"I wish I were too..." she mumbled. He raised his hand and snapped his fingers, and she jumped, then shook her head. "Sorry. That... Archer is here to see you." She spat the Servant's class out with vehement derision.
"Send him in," he said calmly. She nodded, but didn't move. "Rin, please."
"S... can I have a turn next?" she asked quietly. He smiled.
"Whenever she's done, yes, it's your turn," he said with magnanimity. Rin fell to the floor, mewling loudly, and the stench of sex intensified as clear liquid pooled around her.
"T-Thank you!" she moaned, beginning to crawl away. He watched her leave until Rider stopped bouncing and grabbed his head.
"Shirou, please." Her square pupils were close to dilated. "Please, please, please."
"As you wish."
He picked her up by her armpits and stood her up, then spanked her so that she would bend over. He quickly thrust into her again, and her guttural yell of pleasure echoed in the living room.
The door slid open.
"Shirou," Archer said, fully bowing at the waist. "I came to a realization. I was wrong. You and your ideals are correct. The path you will walk will be far superior to my own, and I will—"
"I know." Shirou did not cease thrusting, he only snapped his fingers, and then EMIYA was a woman. "Come here."
Immediately the female Archer fell to the floor, her pants soaking wet. She was unable to get up for minutes, stuck moaning incoherently and drooling as the pleasure of becoming his overwhelmed her.
Shirou was patient with her, though. Because that was what a hero was—patient, kind, and never failing to save others.
Soon, she came to, and then she came to him, crawling on her knees and elbows but so eagerly making her way to him. Her gray eyes shone with desire.
Rider moaned one last time and gushed all over his member, going limp in his arms. He sighed and pulled out of her, gently letting her down. As soon as he let go of her, though, Archer was already in his lap, her cheeks burning in a maiden's demure blush. She latched onto his cock like a woman who stumbled upon an oasis after wandering the desert for forty years.
He peacefully brushed a lock of hair behind her ear and patted her head as she sucked him off.
"Good girl," he said. "You'll learn in time what it means to be a hero. It's the most wonderful thing in the world, I promise."
She moaned, and the vibrations sent him close to the edge. He grunted.
"Take it and learn, you cynic bitch!"
He ejaculated long ropes inside her throat, and for five minutes she gargled on his cum until he was finished. She swallowed it all down easily, innocent eyes glinting up at him.
"I... I understand now," she said. "It's never wrong to save others."
He smiled and cupped her head.
"That's right," he said. "Such a good girl."
