Seamus heard knocking on his door at exactly ten o’clock. Yua and Chiaki had presumably been waiting outside until it was exactly on time. He wondered how long they’d been here, and what they’d heard. He decided it didn’t matter. 

As Seamus approached the door Asuka, who’d been standing facing the wall opposite the door, hands on her head, immediately dived as he’d told her, touching her toes and displaying herself. Seamus opened the door.

He knew there was something like a one in a million chance that the knock had been made by a neighbour come to borrow something, or by some other stranger. Anyone might see her naked, submissive and freshly whipped. He knew Asuka would be thinking the same, and feeling still more deliciously humiliated. 

He opened the door, and of course it was Yua and Chiaki waiting politely outside. They both wore short, tight business skirts, with the tails of their white shirts pulled up and tied so that they showed a lot of their bellies. Seamus said, “Welcome, Yua, welcome Chiaki. Come on in.” But they were already staring, mouths open, at Asuka’s thrashed, crimson bottom and her abjectly submissive display.

Then Yua smiled at him. “You’ve spent your time well, I see. Both of you.” She stepped forward, her feet between his, and wordlessly demanded to be held. So Seamus put his arms around her and she embraced him. She looked up at him, eyebrows up, expecting to be kissed. He obliged. Eventually they stepped apart and she said, “I hope you still have the energy for us, now.”

Chiaki had entered and dropped to her knees beside Asuka, so their heads were close together. “My lovely imouto (little sister), you’re not a little virgin any more, are you?”

Seamus said, “You can speak, Asuka.” He hadn’t forbidden her to speak, but it occurred to him that she’d like the thought that she needed permission.

Asuka said, “I’m a woman. Even up my arse. So I’m your ane (older sister) now.”

“Oh, I’m so happy for you! It was good?”

Asuka nodded, eyes sparkling, like a child asked if she wanted ice cream. Seamus said, “Asuka, you can get up now,. Take Chiaki and serve the sake.”

“Yes, Sensei.” As Asuka walked to the kitchen Chiaki smacked her bottom. Asuka straightened briefly and yelped: she was sensitive there. Chiaki turned and checked to be sure Seamus had noticed. She expected to pay for that later. The two girls talked and laughed in the kitchen, gently warming the sake before pouring.

Seamus smacked Yua, who surely wanted her skin to be as sensitive as Asuka’s was just then. “Undress, Yua. Everything. And if you’re a good girl then I may have just a little energy left.”

Yua said, “Then I shall be a very good girl, Sensei.” She undid the tied shirttails and unbuttoned quickly. She took off the shirt and dropped it at his feet. She had small, round and very pretty breasts, She paused, letting him admire her, then put her thumbs into the little skirt and pushed it over her hips, letting it fall to her feet

Instead of the thing she’d worn that afternoon she’d put on white cotton panties, with her cane stripes escaping the material enticingly at its lower slopes. Then she very slowly pealed them down. Just before her pussy emerged she turned, letting him admire her sweetly striped and slimly feminine bottom. Then she bent forward to let the panties fall to her feet.

Seamus watched, amused but aware that she was having the effect she’d intended. He didn’t let her rise, but put his hands on her hips and thrust his cock, now hard and upright, into her anus, less gentle than he’d been with Asuka. Yua drew in her breath, then exhaled. He wasn’t sure if this had been her preference, but as he began to thrust in her, taking her firmly and fast, it was clear she was happy with his choice.

Chiaki and Asuka approached with sake. He took his and said, “None for Yua.” He smacked her bottom with his left hand, his right raising the cup to his mouth. Something about the change in the sounds she made when he’d smacked her made him spank her again, then again, harder each time. He called Asuka to take the cup and stand beside him, while he gave all his attention to Yua. Yua was yowling now, as he spanked and fucked her. 

He didn’t quicken his pace, or slow down, so she could move with him. He made his blows harder still now he wasn’t encumbered with the cup. At last Yua’s breath caught, and she stopped suddenly so he thrust deeper into her, and then struck her harder. She wailed, and began to move again, frenziedly fast, squealing with a sort of joy. Then she screamed and seemed about to collapse and fall forward, so he had to hold her hips firmly to keep his cock inside her. She slowed her movements, and eventually came to a stop, still panting. “Oh, thank you, Sensei.”

Seamus wanted to come in her then, but he decided it might be wiser to save it. He had responsibilities this night.He slowly withdrew his cock from Yua’s tight opening, and as it emerged Asuka gave his cup to Chiaki, standing next to her, and dashed to the kitchen. She returned with a warm wet cloth.  

Asuka washed me. Yua turned and watched her work. Chiaki laughed. “Yua was going to do that. With her mouth.”

I looked at Yua. “That true, Yua? It’s not very hygienic.”

“It is true, Sensei. I like to do it. It feels right.”

“Well, so long as I emerge clean, at least to my eyes, then I’ll let you. Next time.” 

It struck Seamus that this was a slightly odd conversation, and that giving lordly but grudging permission for her to perform that act on him was faintly absurd. But she was pleased to have his permission, so he said, “Then take my cock in your mouth now. Chiaki, bring Yua’s sake.”

Yua smiled, pleased. She took him deeply into her mouth, barely moving except to stroke him with her tongue once she’d enveloped him he held her tighter, then released her when she gasped for air. Chiaki chose her moment, took the sake in her own mouth and kissed it into Yua’s. 

“Kneel now, Chiaki. Asuka, come here and kneel on Yua’s other side.” So there were three extraordinary girls looking up at him, each with her own motivations, but all enjoying submission in slightly different ways, and all used to playing together. 

He had to give them something as extraordinary as what they were giving him. An idea crossed his mind then became a certainty.
