The crisp autumn air nipped at their noses as Alice and Ethan walked through the park, carrying warm wrapped sandwiches and hot cider from a nearby cafe. They found an empty bench near a quiet pond, where they could sit and talk privately.
“Thanks for buying lunch,” Alice said, taking a bite of her sandwich. “I’m starving.”
Ethan nodded, unwrapping his own sandwich. “Me too. Strategist Lee really worked us hard today. I didn’t expect that using our abilities would work up such an appetite. This morning went really well, though”
Alice nodded, taking a second to finish her bite to reply. “Our essence didn’t last as long as I had hoped. Strategist Lee is right about having to learn to toggle the boost at the right time. It’s going to take a lot of practice to learn how and when you decide to apply the boost. We’re going to have to learn how you think so all of us can be on the same page.”
They ate in comfortable silence for a few moments before Ethan spoke up. “So, we should probably talk about us.”
Alice looked at him, her expression serious. “Yea. I’m not really sure how to start.”
Ethan took a deep breath. “I know I’ve asked this over and over, but it’s important. I want to make sure that both of us are still comfortable with everything that’s happened and where it might lead.”
Alice nodded in agreement. “I’m okay with what’s happened, but I think we need to be honest with each other. We can’t lie to ourselves about where something like this leads.”
Ethan met her eyes. “You’re talking about us having sex?”
Alice met his gaze, her cheeks flushing slightly. “Yes. I mean, we’ve already done a lot together, and I think it’s only natural that things might escalate. We’ve kissed, I came on you, that’s not something to just brush off.” She gave a nervous laugh at her frankness. “It’s sex but it’s not ‘sex’ you know? I want to make sure that we’re both okay with it, the idea that more is going to happen.”
Ethan thought for a moment before speaking. “I’m not going to lie, the idea of having sex with my twin sister is weird. But it doesn’t scare me the way I think it should. I mean, we’ve already done so much together, and it’s been ... intense. But in a good way.”
Alice nodded in agreement. “I feel the same way. It’s like, we’ve crossed so many lines already, and none of them have felt wrong. Just different. We don’t have to rush things just because we’ve talked about it leading there, but I’m glad we’re able to just speak frankly about it.”
“So we keep seeing where this goes, then?” Ethan asked. “To the end, that is. And if either of us get uncomfortable or feel we’re moving too fast, we say something.”
“Yea. Now I kinda think this conversation might end up with us going faster, you know?” Alice paused to take a sip of her cider. “We kind of just agreed to fuck, right? That’s what we’re talking about. Hard to imagine going slower when we’ve already agreed to the end.”
Ethan took another bite of his sandwich before continuing, nearly coughing as Alice put it so bluntly. “I agree and the idea of it excites me, but I think we need to talk about Penny too. She’s as much a part of this as either of us.”
Alice looked down at her food, her expression thoughtful. “I’ve been thinking about that too. I mean, Penny and I have always been close, but lately, I’ve been discovering that some of my feelings for her go beyond just friendship.”
Ethan reached out, taking her hand in his. “It’s okay to feel that way. And it’s okay to act on those feelings, as long as we’re all comfortable with it. I didn’t miss what happened last night between you two.”
Alice looked up at him, her eyes shining with unshed tears. “I kissed Penny this morning while you were sleeping. I didn’t mean for it to happen, but it just felt right in the moment.” She rubbed at her eyes with the back of her hand to banish the tears. “I’m so sorry, I shouldn’t have gone behind your back. It was wrong of me and I’m so sorry.”
Ethan smiled softly at her and squeezed her hand. “Hey, hey hey. I know. I overheard your conversation this morning, but I didn’t want to interrupt your moment together.”
Alice looked surprised. “You did? Why didn’t you say anything?”
Ethan shrugged. “I didn’t want to make things awkward. And honestly, when it happened all I could do was smile. I love both of you, I mean that. Besides, it would feel selfish of me to demand that everything be focused on me and only me ... and I did see the two of you kiss last night. I didn’t feel upset then and I didn’t feel upset this morning, okay?”
Alice put her head down. “I don’t want to make you feel like Penny is cheating on you with me.”
Ethan smiled at her. “I trust both of you. There’s nobody else I love and trust more, but I think we need to have the conversation we’re having now with Penny. I think we’ve all talked separately but there’s no replacing getting together to make sure we’re all together on this. If we talk things out we can avoid the hurt feelings, yea?”
Ethan stood up, moving to the other side of the picnic table to sit next to Alice. He put an arm around her and pulled her close, putting his head down against hers. “I’m serious, okay? I love you and nobody has done anything wrong yet. We’re all feeling this out together.”
Alice nodded her head against Ethan’s chest, sniffling as she cried. “I love you, too”
Ethan put his other arm around her, pulling her into a tight hug. They remained like that, content to be close to each other.
As the hug ended, Alice wiped the tears from her cheeks. “You made me cry, you big jerk.” Alice gave him a playful tap on the shoulder before leaning back in against him.
They sat in comfortable silence for a few minutes before Alice spoke up again. “So, what do you think about Mei? Practice went really well this morning. You could tell she has a lot of experience and knows her class well. Even Strategist Lee seemed impressed. That and she’s definitely got a nice ass.”
Ethan laughed, shaking his head at how quickly her sense of humor came back to her. “I can’t believe you just said that. I’m starting to think you might be an ass woman. The comment at dinner, the way Penny teased you, right now again with her admittedly very nice ass...” Ethan teased Alice.
Alice grinned at him. “What? Maybe I do. You’re no slouch in the nice ass department either, you know. ‘Great Asses’ could be our team name.” She stuck her tongue out at him. “I think she’d be a great addition to the team. Not that any of this matters if her talk with Penny doesn’t go well.”
More seriously, Ethan responded. “I did feel good leaving practice this morning, though. If Penny doesn’t scare her away I think some time in the arena will let us know for sure if she’ll be a good fit.”
Ethan pulled out his phone to check the time. “It’s been about an hour and a half, should I call Penny and see how it went?”
“Text her, they might still be together.” Alice replied, gathering up the trash from their meal and standing.
As Alice cleaned up their lunch, Ethan asked Penny how lunch with Mei had gone.
Ethan: Hey, how’d it go?
Penny: We’re still talking. Not bad so far.
Ethan: Not bad?
Penny: She has some questions. She’s asking if you wanna meet back up? She says she’d rather just talk about it in person.
Ethan: Sure. Where at?
Penny: She has an apartment just off campus, says we can meet up there. I’ll send the address.
Ethan: Ok, We’ll head over.
Penny and Mei walked into the bustling dining hall, the aroma of today’s special filling the air. They grabbed trays and began to fill them with food, chatting casually as they moved through the line.
“Morning training went well,” Penny commented as they found a table by the window.
Mei nodded in agreement. “Yeah, it did. Ethan’s combat boost is impressive.”
Penny took a bite of her meal before responding. “It really is. I’ve never heard of anything like it. We’ve done some testing and the boost is basically doubling our power.”
Mei leaned in slightly, speaking excitedly. “Alice’s lightning strike was insane. I’ve worked with another Shock Blade recently, and Alice was far beyond his strength. Their ranged bolt is good for some damage and drawing attention, but Alice looked like she could kill most common enemies I’ve encountered.”
Penny smiled, proud of her teammates. “Ethan has a very powerful class, but the drawbacks can make it difficult.”
Mei raised an eyebrow. “Drawbacks? The duration Strategist Lee was talking about? I can only imagine how difficult it’s going to be to coordinate that on the fly in a fight. Combat is already hectic enough without having to call out for buffs while you fight.”
Penny hesitated for a moment before answering. “It’s ... more about how to refill essence that makes it difficult.”
Mei had a confused look on her face. “Is it not like mana? I heard you use the term today but I just assumed it worked similarly.”
Penny took a deep breath, preparing herself for the conversation ahead. “Ethan’s class is ... well, this is why recruiting is a delicate matter for us. It’s part of why I wanted to get lunch with just the two of us.”
Mei gestured for Penny to continue.
“Okay, just go with me on this one. I know you’re not going to believe me, but I swear I’m telling the truth. Penny took a deep breath. “Ethan’s class is sexual.”
Mei stared at her, disbelief written all over her face. “Very funny. Good joke.”
“I’m not joking, I told you that you wouldn’t believe it.” Penny replied with a serious expression.
Mei took a moment to stare at Penny, expecting her to laugh any moment. “Like, he has to have sex to use his powers?”
Penny nodded. “Yea. It sounds like a made-up joke just to get women to sleep with him, but it’s true. You saw the results of his class this morning. Alice and I were hitting almost like we’ve had our classes for years, right? That sort of combat boost doesn’t come for free. Combine that with his healing and you’ve got an S rank class.”
