The training arena buzzed with the hum of automated dummy constructs, their joints whirring as they moved around the party. Trainer Harris stood on the control platform to the side of the arena, directing the dummies in a pattern designed to trip up the team.
Ethan swore as a dummies sword smashed into the shield he was carrying. “Alice!” He shouted as the dummy moved past him and into her blindspot. Penny’s Shadow Minion was there, tackling into the dummy, throwing it off course just enough for Alice to dodge.
Penny cried out and Ethan turned towards her to see her kneeling, with a dummy backing off.
“You can’t leave yourself open like that just to save someone else!” Trainer Harris yelled at Penny, signaling the end of the training round. She stood up, rubbing her thigh where she had taken the blow.
Ethan walked over to Penny, placing a hand on her shoulder to heal the wound. “You’re almost out of essence.”
“Think you have enough to cover me for another round?” Penny asked, still rubbing the phantom pain where the dummy had hit her.
“One more, at least.” Ethan nodded to her. He spun to look at Trainer Harris and yelled out. “I have enough essence for one more round, and then we’ll be spent!”
“Then you’ll have to fight without essence! Best not take another hit!” Harris shouted back.
The group shared a look with each other before getting back into position, knowing full well that Harris meant exactly what he said. A trio of fresh dummies came out, and as Harris signaled the start of another round, they came forward in yet another new formation.
Penny began with summoning her Boosted Shadow Minion. She sent it ahead, Ethan dropping the Boost after her summoning as they had practiced. Alice moved left, intending to intercept another of the dummies.
She met the blow from the dummy on her small round shield, redirecting the blow, reaching out with her rapier in reply. The dummy dodged her attack and she swore silently as missed. She parried the next strike, moving past its guard and touching the edge of her shield against its arm. A loud crack sounded out as she channeled a Shock through the shield and into the dummy.
“Alice, right!” Shouted Ethan.
She felt the telltale signs of Penny’s Shroud falling around her, blinding their enemies while leaving her own vision unimpeded. She stepped to the side, narrowly moving past a blow meant for her from the third dummy. The dummy spun, trying to strike her through the darkness. She struck the wrist of the dummy with the tip of her blade, sending a Shock into it.
Ethan slammed into the first dummy a moment later, leading with his shield. Alice quickly followed up, making use of his opening to send a second Shock into the first dummy, incapacitating it. The two of them glanced around as the dummy fell to the ground, assessing the fight.
They saw it together, the second dummy moving out of the Shroud to attack Penny.
“Go!” Ethan shouted.
Alice shot across the training yard, rocketing forward with a Boosted Shock Blade Surge. She was there before Penny could call out for help, her blade thrusting into the dummy’s internals as she let loose with a Boosted Shock. The dummy began to twitch violently, the servo motors driving its limbs going haywire before it fell to the ground unmoving.
Penny gave a quick nod to Alice as she summoned a Boosted array of Shadow Bolts to attack the dummy her Shadow Minion was occupying. Just as the dummy managed to finally throw off the Shadow Minion, the Shadow Bolts impacted, staggering it backwards. Moments afterwards, Ethan came in swinging with his mace to finish the job and cracked the dummy center mass, knocking it to the ground and out of the fight.
All three moved back into formation as Trainer Harris signaled the round over.
Harris jumped down from the platform, walking over to the team. “Finally.” He grumbled, though his scowl softened as came closer. “You waited until the end, but you managed to pull it off.”
Harris continued on. “Good call outs and target swapping, you two.” Harris nodded towards Ethan and Alice. “I also saw that boost timing to nail the second dummy as it was getting away. That’s the sort of usage we’ve been talking about. Now you just need to do it a thousand times until you can coordinate in your sleep.”
Harris turned to Penny last. “Keeping the third dummy locked down while still providing support was a good spread on your abilities. Like the round before last, though, you need to keep a better eye for your own safety. If Ethan and Alice hadn’t taken care of that dummy, what was your plan?”
“Shadow Bolts.” Penny answered. “It’s why I was so quick on the redirect towards the final dummy. I was initially planning on defending with the spell.”
Harris nodded. “Good. Next time, consider repositioning as well. If you had moved left, the dummy would have been forced to go around Alice. As it was, it had an open path to you.” He turned his focus back to Ethan. “Did Alice Shock the second dummy before she took it down with a Boosted Shock?” He quizzed.
“I’m ... not sure.” Ethan got out after thinking for a moment.
“As support, It’s your responsibility to keep track of the fight. Jumping into the melee is fine, but don’t neglect the small details.” Harris lectured.
Alice knew her time was next as Harris looked at her. “Why didn’t you Shock through your blade on your parry?”
“Strategist Lee instructed that Shock is preferably conducted through direct contact with the target, sir” She replied.
Harris shook his head. “Textbook. Not good enough. You won’t always be up against something that you can get close enough to touch. Don’t be afraid to use back to back Shocks. Shock Blades are fast and deadly, not suited to a drag out fight. End your skirmishes quickly.”
“Understood.” Alice nodded.
“Dismissed.” Harris let out, already turning away from the team.
“This’ll get easier with a full team, right?” Penny complained. “I think most of my essence was spent healing me rather than Boosting.”
“Once we get a defender Ethan will be able to stay closer to you. Until then I expect Harris is going to keep picking on you.” Alice replied, her mouth twisting. “He was playing dirty, though. That dummy shouldn’t have been able to beeline towards you from within the shroud.”
Ethan shook his head. “No, he was right to do it. We don’t know what sort of senses the monsters in a dungeon will have. They could have sonar for all we know. We just have to be ready for it like we were today.”
The group made their way out of the training yard and into the locker rooms. As Ethan moved to split off into the men’s, Penny reached out for his arm. “Wait.” She had a naughty smile on her face. “How about a refill on essence?
“Here?” Ethan was surprised.
“You know nobody is around, there’s a reason they picked this old building on the edge of campus. They didn’t want people snooping on their new S rank.” Penny began to plead, putting on her best puppy dog expression. “Please oh please won’t you come fill me up?”
“You better listen to her.” Alice laughed. “If you don’t she’s just going to end up masturbating in the shower again.”
“Alice!” Penny scoffed in mock offense. “I would never!”
Ethan gave in, grabbing Penny by the hand and leading the way into the women’s locker room. “Fine, I’ll give you what you want.” He set down his gear, turning to her. “Strip.” He commanded.
“Yes, Trainer Ethan.” Penny teased, her expression serious.
“Uh, gross.” Alice said with a disgusted look. “Let’s avoid bringing Harris to mind, thank you.”
Penny and Ethan laughed together. Penny quickly stripped, presenting herself for Ethan. Alice stood close, watching Penny with him. “How should we take her?” She asked Ethan, looking as Penny stood naked for them.
“We?” Ethan questioned Alice. “Strip.”
Alice smiled as she began to get out of her training gear. “Yes, Trainer Ethan.”
Penny did a terrible job trying to keep her serious face, breaking out into giggles as Alice taunted Ethan.
“Alright, trainees,” Ethan began, his voice taking on a playful, authoritative tone. “Since you both seem to think you can tease me without consequences, let’s see how you handle some real training.”
Penny and Alice exchanged excited glances, giggling together at his antics. They stood side by side, shoulders touching, their backs pressed against the cool tiles of the locker room wall.
Ethan stepped close, his hands reaching out to cup each of their breasts, squeezing gently. “First lesson: obedience.” He commanded, his voice firm. “Spread your legs.”
The women complied, spreading their legs apart to give Ethan better access. He moved his hands down, tracing the curves of their hips and thighs before finally reaching their pussies. He began to tease them, circling their clits and dipping into their wetness.
“Let’s see how long you can last.” Ethan murmured, his voice low.
He increased the pressure and speed of his fingers, making sure to give both women equal attention. Penny and Alice moaned in unison, their bodies writhing against the wall as Ethan’s fingers brought them closer to the edge.
“Ethan...” Penny gasped, her voice pleading.
Ethan hushed her, his fingers never slowing down. “You’ll get what you want when I say so.”
Alice whimpered, her hips bucking against Ethan’s hand as he brought her closer to the brink of orgasm. “Ethan...” she begged, dragging out his name.
“Together,” Ethan commanded, his voice firm. “Come together for me.”
They cried out, their bodies tensing as waves of pleasure washed over them. Ethan’s fingers continued to work them, drawing out every last drop of their orgasms until they were left panting and spent.
Ethan pulled his hands away. “Good girls,” he praised, his voice softening. “Now it’s my turn.”
Hands on their shoulders, he positioned them before him. Penny and Alice looked up at him from where they knelt, their faces written with expressions of lust and anticipation.
Ethan took hold of his cock, lifting it above them, straight out from himself.
“Begin.” He commanded.
The two began to work in unison, their mouths and hands moving in sync as they pleasured Ethan. They took turns sucking on his cock, their tongues swirling around the sensitive tip before taking him deep into their throats. Ethan groaned, his hips bucking slightly as he fought to maintain control.
Penny reached up, placing a hand on Alice’s head and guiding her movements. “That’s it,” she murmured. “He likes it best when you suck just on the head.” Alice complied, her lips wrapped tightly around the head of his cock. Penny guided her into a rhythm, showing her exactly how Ethan liked his sock sucked.
Ethan groaned loudly, his body tensing as he reached his climax. He came hard, his cum shooting out in thick ropes and filling Alice’s mouth. Penny guided Alice to hold it. “Don’t swallow yet. He loves to see it.” Her hand still on Alice’s head, she ensured that none of Ethan’s cum was wasted. As Ethan’s cock finished throbbing, Penny pulled Alice off his cock. “Now show him.”
Alice looked up, opening her mouth. Ethan looked down, seeing her mouth full of his cum, the sight intoxicating. He put a hand on her, closing her mouth.
“Swallow.” He commanded.
Alice swallowed eagerly, working to take down every last drop. She pulled back slightly, sticking out her tongue to show that there was nothing left in her mouth.
“Good girl,” Ethan praised, his voice soft and satisfied. He reached down, pulling both women up to their feet and into a kiss. Penny and Alice kissed deeply, their tongues tangling as they shared the taste of Ethan’s cum.
Ethan watched them, his heart swelling with love and desire. He pulled them both close, kissing each of them in turn before stepping back. “Now, get cleaned up,” he said, his voice gentle.
They nodded, their bodies still humming with pleasure as they made their way to the showers. The hot water ran over them, washing away the sweat and grime of training but leaving the lingering scent of sex in the air.
The coffee shop on campus was quiet, the aroma of freshly brewed coffee filling the air. Mei sat at a corner table, nursing her latte as she waited for Penny. When she arrived, Mei waved her over, waiting while Penny ordered.
“Thanks for meeting me,” Mei said as Penny took a seat across from her.
“No problem,” Penny replied, “How have you been?”
Mei shrugged slightly. “I’ve been thinking a lot about what you all told me. I have some more questions if that’s okay.”
Penny nodded. “Of course. Ask away.”
Mei took a deep breath and leaned forward to speak quietly. “So, if I join the team, what exactly would I need to do for bonding and essence generation? I want to be clear on what’s expected of me.”
Penny took a sip of her coffee, thinking carefully about how to explain it. “The way things work is completely in your hands, Mei. We’ve discussed this as a trio, and we know that adding you to the team is going to put you on the outside looking in due to how long the rest of us have been together.”
Mei nodded, understanding the dynamics at play. “I see. So, what does that mean for me?”
Penny continued. “It means that we don’t want to put any expectations on you that you didn’t agree to. We know it’s not fair to assume anything. If you join, you’ll have the final say in how things progress. Ethan’s class requires essence generation through sexual acts, and the more intimate and intense those acts are, the more essence is generated. Like we explained before, though, the single easiest way to generate essence is an orgasm.”
