The trio made their way back to Ethan’s dorm room, the walkways of the training campus full of other Class Marked going about their days. The weight of the morning’s revelations about the significance of Ethan’s class hung heavy in the air, and each of them were silent as they went over their morning in their heads. As they entered the room, Penny took the lead, her voice steady and determined.
“Alright, let’s talk about this,” she said, gesturing for them to sit down. Ethan and Alice followed suit, taking seats on the bed and the small love seat respectively. “Clearly the political implications of your class are huge, Ethan. The guild is taking this seriously, and we need to be prepared for what’s coming. An entire team of advisors, ready to meet us at a moment’s notice? The guild is clearly taking you having an S rank class seriously, and we should as well.”
Ethan nodded, his expression grave. “I know. They made it pretty clear that there are a lot of expectations for me. Being S ranked is one thing. They have experience with that. The idea of permanent growth from Essence Imbuement seems to have been all they could focus on, though. I knew that it would be a big deal, but I think I underestimated how they’d react.”
Alice chimed in, her voice thoughtful. “The advisors they assigned to us aren’t just random, either. Each of them are the heads of their respective departments, and they’re all at least B ranked. I think Mage Thompson is related to the Guildmaster, too.”
Penny agreed. “Exactly. And the question about why you’re working with D-ranked teammates ... it’s clear that they want the best possible team composition. But we know each other, and we trust each other. I just worry that’s not going to be enough. Trainer Harris was pretty clear about where he stood, even if Mage Thompson took our side.”
Ethan took a deep breath, feeling a sense of determination wash over him. “I agree with Harris to a point. The idea of making A-ranked Marked even stronger is an obvious application of my abilities. You heard Thompson about the rise in S-ranked Dungeons appearing ... But I still believe trust and synergy are crucial when I have a class this weird. We’ve trained together for years, and I believe in our abilities. I was serious about not intending to let them pick and choose my teammates just because of my class. We’ve all planned to work together for years and that hasn’t changed.”
Alice nodded. “They did seem to understand that we had a history together, but I’m not sure how much that will matter to them if we can’t show results. Trust and synergy are great, but they can’t make up for the disparity between class ranks.” She paused before continuing. “I think we need to start testing the limits of your class and see how the long-term growth manifests. The advisors want to conduct extensive tests, and we should be prepared for that. If it’s possible the long term growth could make up for us being D ranked...” She trailed off.
Penny leaned forward. “I have an idea. We should test what the bare minimum for bonding and Essence generation is. Remember when you and I felt essence from just a kiss? Maybe that’s all it takes.” She said, speaking to Ethan.
Ethan looked at Penny, surprised but intrigued. “That’s a good point. If we can generate essence through a simple kiss, it might be worth exploring. It could be the bare minimum for bonding. If we could find a way to create Essence without going further...” He left the rest of the statement unsaid.
Alice hesitated before speaking. “I’m not sure how I feel about this...”
Penny reached out to take Alice’s hand. “We can figure this out together. We’re all in this as a team and we can’t let anything get in the way of that.” She met Alice’s eyes. “What do you think? Should we try it?”
Alice looked at both of them, her expression thoughtful. “Alright, let’s do it. But let’s set some ground rules first. This is just an experiment, and we need to keep it professional.”
Penny nodded in agreement. “Absolutely. We’ll start with a simple kiss and see how it goes. If we feel essence generation, we can explore further. But for now, let’s keep it at the bare minimum.” Penny pulled Alice to stand up, gesturing for Ethan to come over. “We know from last night that even a quick kiss can generate Essence. A quick peck, the same type of kiss you’d give an aunt, okay?”
Alice nodded, still seeming unsure, but willing to give it a shot. Ethan moved forward to stand close to Alice, feeling the moment grow awkward as the waited for the other to make the first move.
“A quick peck, right?” Penny reminded them.
Ethan looked back to Alice, seeing a mix of emotions on her face before it resolved into a look of determination. “Okay, fine.” She said, closing her eyes and puckering her lips. Ethan did the same, leaning forward. As their lips met, Alice jumped back in shock. She had felt the essence they had told her about, not expecting to feel it so quickly. “Uhm, wow, okay. I definitely felt something.” she said while nodding.
“I did, too” Ethan replied. “I wasn’t able to activate my bonding skill, though. We pulled away too quickly.”
“So hold it longer?” Penny suggested.
Alice nodded, closing her eyes and puckering her lips. Ethan moved in again, pressing his lips awkwardly against Alice’s, waiting for the feeling of essence to activate his bonding ability. As he felt the essence begin to build, he reached and tried to activate the skill ... and got rejected. He pulled away and spoke. “I don’t think it’s enough essence to offer a bond. When I tried to activate the ability, it failed.”
“The way the two of you are going about this isn’t helping.” Penny chimed in. “Look at you both, you’re standing so far apart you have to lean forward at the waist as awkward as middle schoolers kissing for the first time. And neither of you know what to do with your hands, just letting them dangle. If the Essence generation is actually tied to intimacy, I doubt the sort of kiss that makes a person cringe just seeing it is going to cut it.”
Penny stood up and turned Ethan towards herself. “Like this.” she said as she grabbed his hand and leaned in to give him a peck. She felt the essence present in the kiss and pulled back. “Was that more or less essence than before?” she asked.
“It was a bit more, yea” Ethan replied, feeling a bit awkward.
“Ok, then let’s try this.” Penny said as she grabbed his hands and put them on her waist. She leaned in and gave him another kiss. “How about that?”
“A bit more than before, for sure.” Ethan’s cheeks turned red as he blushed, still holding onto Penny’s waist.
This time, Penny leaned into Ethan, pressing her body against his as she kissed him for a third time. She held the peck for longer, the kiss lasting for a few seconds. “That has got to be enough essence, right? She exclaimed as she pulled away from Ethan. She took Ethan by the shoulder and turned him, pushing him towards Alice. “Let’s see you try again like that. A peck, but intimate.” she said to Alice.
Alice stood there, eyes wide and cheeks red as Penny demonstrated the kiss. “Hey, you can do this.” Penny said softly to Alice. Alice gave a small nod in reply, still looking anywhere but Ethan. Penny grabbed Ethan’s hand again and placed it on Alice’s waist, pushing Alice closer to Ethan by the small of her back. “Try again like I showed.” Penny instructed.
Ethan and Alice were only inches apart now, one hand on her waist, with Penny’s hand holding it here. Alice closed her eyes once more as Penny brought the two together. Ethan felt Alice press against him, her face turned up towards him as he brought his lips down to hers. With Penny holding them there together, the kiss was far beyond their first awkward attempts. They felt the essence building as they kissed until the threshold was broken and Ethan offered Alice a bond.
Alice felt the bond being offered to her and hesitated for a moment, a small feeling of panic rose in her chest causing her to pull back away from the kiss. She took a few steps backward and began apologizing. “I’m sorry, I don’t know what happened, I ... I...” She stammered, feeling a bit overwhelmed in the moment.
Penny went to Alice and pulled her into a hug, apologizing to Alice herself. “I’m sorry, I shouldn’t have pushed you.”
Alice shook her head as they hugged. “Don’t, you didn’t do anything wrong, the whole day with everything just hit me all at once and I started to freak out a bit.”
Ethan was standing distraught at the thought that he had hurt Alice, unsure of how to comfort her. He felt angry at being given such an unbelievably bullshit class. S ranked but he had to kiss people just to make it function? Whose idea of sick joke was this? All of this power but the cost was hurting the people he loved?
Ethan began to speak as Penny and Alice pulled apart, wanting to express his frustration at the situation. “I’m sorry Alice, this entire situation is stupid. We just got our classes and I think I might be rushing things. Everything about my class is bizarre and I shouldn’t be putting you in this situation, I’m not sure what came over me. There’s no excuse.”
Alice shook her head, listening to Ethan as him blame himself. “You didn’t choose this class.” Alice said, unknowingly echoing what Penny had expressed the night before. “We’ve spent the past five years since we first received our Marks training for this. Just because it’s weird doesn’t mean I want to throw everything we’ve been working towards away. I just freaked out a bit, that’s all. I still want to team up with you both.” Alice took a few steps towards Ethan, grabbing his hands and putting them on her waist herself. “Let’s try again. I’m going to accept this time. I felt the offer, so we know it can work. Alice sounded decisive as she spoke.
Ethan knew when his sister had made up her mind, and he could tell this was one of those moments. He chose to trust her, pulling her against himself as they went for another attempt at Bonding. As their lips touched, the Essence rushed up far quicker than before. It was almost as if the hesitancy from their earlier attempts had been inhibiting them, their nervousness blocking the Essence. Ethan activated his skill, offering Alice a Bond and he felt her accept it immediately. The rush of essence hit them both hard, Alice let out a moan as her knees went weak. Ethan felt her legs bend and held tight to support her. As he did, they became unbalanced and stumbled to land onto the loveseat next to them. They fell with Alice on top of Ethan and Alice tucked her head against Ethan’s chest as he felt her entire body go stiff.
They sat there for a few moments as Alice came to from the intense feeling of the bond. She felt mortified, her head still pressed down against Ethan’s chest where it felt like she could hide. She couldn’t believe she had just cum while kissing her brother. While laying atop her brother. If she could just keep hiding her face...
Ethan held completely still as Alice lay on his lap, his cheeks burning bright red, self conscious about what had just happened and how he was reacting to it.
“Alice, are you okay?” Asked Penny as she knelt next to them on the couch, pulling some of Alice’s hair out of the way to see her face. Penny could see how flush Alice was and combined with the expression on her face, Penny could tell what had just happened.
Penny met Ethan’s eyes and realized that if Alice had reacted that way, then Ethan must have as well and that meant... “Ethan, could you go down to the common area and grab us something to drink?” Penny asked him.
Ethan nodded his head and helped Alice move off of him to sit on the couch. He looked at Penny as she mouthed to him silently to give her and Alice a few minutes. He had no problems doing that, having a strong guess as to what had just happened.
As Ethan left the room, Penny turned to Alice to ensure she was okay. “Alice...?” She trailed off, looking at her friend.
Alice took a minute before she replied. “I’m okay. I just ... I didn’t expect that to happen.” Alice said, intentionally looking away from Penny.
“I’m sorry.” Penny replied. “When Ethan and I bonded we were already, well, we expected it to be ... Explosive. I should have thought about that before I suggested we try this.”
Alice gave a small laugh. “Hah, explosive is right. I would have fallen if he hadn’t caught me. For a few moments there my mind just went blank.” Alice sat up and glanced sideways at Penny, beginning to laugh. “If you had told me yesterday one of the best orgasms of my life would have been from kissing Ethan I’d have called you crazy. The intensity of the Essence was unbelievable.”
Penny laughed along with her. “I know what you mean. I think he and I laid there for 5 minutes afterwards before we were even able to speak.” She turned sideways on the loveseat, folding a leg beneath her to face Alice. “But it worked, right? The bond. Show me your class mark.”
Alice turned to show Penny her back. Penny grabbed the hem of her shirt to pull it up and sure enough, Alice’s Shock Blade Mark had the same intricate circle overlaid on it that her own Dark Weaver mark did. Penny stood up and pulled Alice up by her hand to the mirror on the closet door. “Look at it.” She said, positioning Alice and holding her shirt up for her.
Alice looked over her shoulder to the mirror and could see the change her mark had undergone. Mixed into her mark as if it was always designed to have it was the intricate circle of Ethan’s class mark. Alice stared at it, an odd feeling she could only describe as... ‘pride?’ welled up in her at the sight. “Did yours change, too?” She asked Penny.
Penny turned around and pulled the back of her shirt up, revealing that her own class mark had the same intricate circle design worked into it. At that moment, the door to the room opened and Ethan poked his head in.
“Is it okay for me to come back in?” He asked the girls. Seeing them nod, he opened the door the rest of the way and handed each of them their preferred choice from the vending machine downstairs. “Again I’m really sorry that-” Ethan got out before he was cut off.
“Nope.” Said Penny.
“Stop.” Said Alice at the same time.
The women looked at each other, Penny signaling that Alice should go ahead.
Alice looked back at Ethan “You don’t have to apologize for this. Again, you didn’t choose your class and I was the one who chose to go through with attempting to bond. I don’t want to hear you say sorry again about this, okay?” Alice reprimanded Ethan.
Ethan nodded. “Okay, I get it.”
“Good.” Alice replied.
The three of them stood there for a few moments longer of awkward silence until Penny popped the tab open on her drink. Alice and Ethan looked towards Penny as she stood there frozen in the act of opening the drink. All three laughed as the tension was broken, glad that the moment had passed.
The trio sat down in their accustomed spots in the room, the tension broken by Penny’s laughter.
“Alright, let’s talk about this bonding thing,” Penny said, her tone more serious. “It worked, right? We felt the Essence generation, and the Bond was established.”
Ethan nodded, his expression thoughtful. “Yes, it did work. The Bond is solid, and I can feel Alice through it just like I can with you. It’s amazing how quickly it happened.”
“And now we know that a simple toe-curling kiss can generate enough Essence for a Bond.” Penny continued. “We need to start testing the limits of this and see how far we can push it.”
Alice agreed, giving Penny a stare for her joke. “How much Essence do we need to test out your abilities?” She questioned Ethan.
“Penny and I had enough to test things out this morning.” He replied, closing his eyes and feeling at his Bond with Alice. “It feels like the Bond is empty. We were able to create a trickle of Essence as we cuddled last night, so we can try that?”
