Kat stepped inside the bedroom to let her past, and Selene was off, presumably making coffee around the corner. Arthur stood up from the bed, stretched his neck, rolled his shoulders, and popped his back by flexing it just the right way.
“Is it a date?” Arthur asked as he started opening the drawers. “Selene keeps calling it that, but I wasn’t sure.”
“It’s…” Kat started, then hesitated. “It’s lunch.” She said finally.
“So it’s just lunch because you want to talk. Not a date.” Arthur clarified. “I’m just… trying to figure things out.”
“Do you want it to be a date?” Kat’s question had an edge of challenge that made Arthur unsure how he should answer. If he said no, Kat might think he hated her. If he said yes, she could call him all kinds of names. There was no winning in this scenario.
“I think that’s what I’m asking you.” Arthur countered. “In my experience, it’s not a date unless the woman says so.”
“It’s…” Kat seemed to think about it for a moment. “It’s an opportunity.”
“What’s that supposed to mean?” Arthur asked, more confused than ever as he pulled the clothes he needed.
“You’ll find out at lunch.” Kat smirked and then left his room and headed into the kitchen.
Arthur watched her head into the kitchen, unsure what that meant. He sighed, headed into the bathroom, and started the shower water. He brushed his teeth, shaved, and then hopped in the shower. He was part way through lathering himself up when he heard the bathroom door open.
“Master?” Selene’s voice was quiet but steady.
“Yes?” Arthur asked.
“Do you need any help?” Selene asked.
“Showering?” Arthur asked for clarification as he ran the soap bar across his chest.
“Whatever you need.” Selene volunteered. “If you’re still horny, I can always stroke your cock.”
Arthur’s dick twitched a little at that thought, but just a little. He smirked. He supposed even he needed a break from time to time. “I think you did a good job of that earlier. I’m still recharging.” He answered with a chuckle.
“Oh, okay.” Selene sounded disappointed.
“I could use your help with something, though.” Arthur said as he washed his legs.
“Of course, whatever you need, Master.” Selene answered more cheerily than before.
“Your sister.” Arthur said, as though that statement was itself explanatory.
“What about her, Master?” Selene asked.
“What does she want from me?” Arthur asked, slightly frustrated but trying his best not to let it show. He set the soap and the washcloth down and started rinsing himself off by starting with his already shampooed head.
“I’ve been telling her about everything you’ve been teaching me about… about my sexuality. And all the orgasms you’ve given me, and how wonderful it feels to be your slave.” Selene answered as though that explained things. “She hasn’t had a boyfriend in a while and can be a bit bratty. A handful. She needs someone who can rise to that challenge, and I told her I thought you could and would if she asked you.”
“And what did she say to that?” Arthur paused.
“She said she’d text you.” Selene’s smile was audible in her voice. “And then she did, and set up a lunch with you to talk to you about it without me around so the two of you can get to know one another and have some privacy.”
Arthur was silent as he continued rinsing himself off. His mind was racing as he thought about the consequences and possibilities. “Does she… want to be my slave too?” He asked.
“I don’t think she wants quite the same thing we have.” Selene explained. “But I know she enjoys certain things just like I do, in her own way. And I know she won’t try to steal you away from me. A little competition between us might even be a good thing. For you, anyway.”
“You really are trying to make me a harem, aren’t you.” Arthur laughed as he turned off the water.
“Of course, Master.” Selene smiled up at him from her place, kneeling on the bathmat, as he opened the shower curtain. His towel was draped across her upraised arms, and he took it from her and started drying his hair. “If I had my way, I’d build you a whole stable full of women to fuck whenever you wanted, so long as you still used me as your slave when you were done with them.”
Arthur’s dick twitched again, remembering how hot the blow job had been while he detailed his date with Kelly and the sex they had together. It’d also been enjoyable for Selene, judging by her reactions to it. Selene must have seen it because there was a hunger in her eyes a moment later when he finished drying off.
“Do you want me to suck you off before your lunch, master?” She asked, hopefully.
Arthur considered it. “No.” He finally decided. “In fact, I want you to take some time off while I’m at lunch to finish your homework and do what you’d normally do on the weekend.”
Selene looked like he’d slapped her across the face and not in a fun way. “Do you…” Her voice broke. “Do you want me to take off my collar?”
“No.” Arthur assured her. “You’re my slut. You can wear that, or one of your other collars, for as long as you want to. But you do still need to live your life. You can’t spend all day, every day laying at the foot of my bed waiting for me to come home so I can fuck you.”
Selene seemed to consider that statement for a moment, and Arthur realized that she’d taken the opposite meaning from it. He’d meant to explain the obvious. Instead, he’d given her something to aspire to, something he feared was far too unrealistic to be attainable.
“Selene…” Arthur warned.
“I know, I know.” She frowned and looked down at the floor as she shifted into the Nadu position. “A slave may dream, Master. A slave may dream.”
Arthur shook his head. “Any other insights you can give me about your sister?” He asked as he slid on the pair of boxer shorts he’d brought in with him.
“Don’t be afraid to be mean to her. To be forceful. She will push the boundaries. She’s not as…”
“Obedient?” Arthur volunteered.
“Yeah.” Selene nodded. “She’s not a good girl, Master. She will push you. You must push back, or better yet, push her first.”
“Okay.” Arthur thought he could do that. “Where should I take her for lunch?”
“You should order in. I… may have told her you said you would meet her at our apartment and that you would order sandwiches for lunch.” Selene did her best not to smile but failed under Arthur’s incredulous gaze. “She’s waiting for you there.”
Arthur laughed. “You’ve thought of everything, I suppose.” He pulled on his shirt. “What will you do when she joins my harem? Share my bed with the two of us? Suck me off after I finish fucking her like you did with Kelly?”
Selene shuddered.
“Will you serve her, like you offered to serve Kelly?” Arthur asked.
“No.” Selene said. “I… I don’t think she wants that. We don’t want to do anything sexual to each other. But… we both think it might be exciting to do things to you or have you do things to us simultaneously.”
Arthur’s dick started to harden at the thought of it. A threesome with sisters? That was definitely on his bucket list of ‘things that will probably never happen but would be cool if they did.’
“You could take turns having us blow you or fucking us while the other watches.” Selene said quietly. “Whatever you wanted.”
