The next day, Akeno woke Abaddon up with an amazing service that was reminiscent of Aika before they both moved to the gym area.
"Can you wear this?" Abaddon asked as he handed Akeno a loose tank top. She had already put on some yoga pants that hugged her amazing legs and booty, displaying her curves proudly. The belt was enchanted and seemed completely invisible under the pants even though they hugged her figure tightly.
"I'll try…" Akeno said, glancing down at her chest, specifically at her swollen nubs that were still extremely sensitive. She had noticed that Abaddon's Aether seemed to have relieved all her fatigue and brought her back to top shape except for her nipples. She was sure that it was a deliberate action from him.
She slipped the tank top over her head and let it fall down to her torso, leaving a thin part of her belly visible like a crop top, "Ahn~" She squirmed as the top rubbed against her nubs and made her recoil. It pulled the top around and only caused her nipples to rub more against the material. She then found Abaddon's hands reaching her shoulders as he stabilized her in front of him. Akeno continued squirming for a moment before stopping and quickly pulling away the tank top, "Too sensitive…" She said with a deep breath as she pressed her legs together.
"More eye candy for me…" Abaddon laughed in appreciation as he looked at Akeno's chest.
She rolled her eyes, "Can we start the training?" She asked with a soft voice, "A-kun~"
Her sultry voice tempted Abaddon to go for another round, but he decided to train a bit first. "Right," Abaddon said before casting two large spell circles that weren't complex but had some differences between them.
"What's this circle for?" Abaddon asked her as he pointed to the circle that seemed to have less number of different lines and runes.
"It's a basic fire emission spell," Akeno said.
"Yes." Abaddon nodded and cast the spell, causing the circle to release a breath of fire like a flamethrower, "What about this?" He asked as the circle disappeared.
Akeno didn't recognize the circle at a glance so she started deducing the spell through the different aspects of the circle, "Basic element, release, burst..." She deciphered a few aspects for a few seconds before concluding, "It's the same fire emission spell. But it seems to have some extra steps involved that I can't recognize."
"It does," Abaddon nodded, "That's spell compression."
He cast the spell and instead of a breath of fire, a tiny crystal was released from the circle. As Akeno closely looked at it, Abaddon snapped his fingers and the crystal burst into the exact spell that it was supposed to be and released a wave of fire in a single direction.
"Is that it?" Akeno asked, "This seems like an interesting ability, but I don't think that there are a lot of applications to it…"
"But there are…" Abaddon said with a smile, "That little crystal you saw, essentially acts as matter. Unstable matter, but matter nonetheless. Do you know what that means?"
Akeno gasped, "You can collect these compressed spells and use them like instant cast spells. Not to mention the ability to store them in spatial storages…"
"You still didn't get the best use," Abaddon said, "You can chain spells in the middle of a battle."
Seeing Akeno's confused expression, Abaddon created a double-layered circle and cast the spell. The same crystal of fire was what came out of it, but it instantly appeared on the other end of the room, without needing any sort of time. Her eyes widened at the display.
"Yeah, that's the reaction that I wanted to see…" Abaddon nodded with a hint of pride, "Using teleportation spells on compressed spells, I can teleport hundreds of spells directly on the enemy without them ever realizing that they were attacked."
"Can you do it with lightning?" Akeno asked him, "Lightning is much more volatile than even fire."
"I can," Abaddon said, "But it is undoubtedly much more difficult to compress lightning enough that it doesn't destabilize when going through the space spell. Since you're starting from scratch, you'll probably end up using the rest of our training to learn it."
"I don't mind," Akeno said, "Since my specialty is lightning, I would rather focus on it completely."
"Okay then let's start," Abaddon said.
…
The rest of the training time passed relatively uneventfully. Abaddon and Akeno spent most of their time training spell compression. Akeno had to cover a steep learning curve and kept focusing on being able to compress her lightning while Abaddon was working on perfecting his control over the other elemental spells.
By the end of the training, Abaddon had very good control over almost all elemental spells and he could teleport any spell he wanted to within a distance of one mile or so. The only element that remained was Destruction. Since it is such a volatile power, it was almost impossible to stably compress it to be able to teleport it over. He made significant progress, but he was still ways away from being able to teleport even the weakest Destruction energy attack.
On the other side, at all times that Abaddon wasn't training, he was relentlessly teasing Akeno, making sure to keep her orgasms under control, only allowing her to get one every week. Weirdly enough, Abaddon felt that Akeno was even more motivated to serve him than before as the weeks passed. Her affection for him only seemed to grow as he kept her caged in her chastity belt at all times, only focusing on her ass to tease and pleasure her.
He didn't think too deeply about it, focusing more on enjoying his time with his denied devil who also helped him immensely with his training.
They ended their training session on a high note with Abaddon allowing Akeno a cheat orgasm even though it had been two days since the previous one.
They both dressed themselves up appropriately and teleported back up to the house, in the living room. Abaddon noticed a sensor spell having been placed there and frowned for a moment before detecting the familiar magical signature of Rias on the spell.
"I have to go help Buchou, A-kun," Akeno smiled sweetly and kissed Abaddon's cheek, "I really enjoyed our time together." She said before casting a teleportation spell under herself.
"What a disappointing way to leave your master," Abaddon said with an irked tone and grabbed Akeno's nape before pulling her close to himself, forcing her to step out of the magic circle as he pressed his lips against hers.
She moaned while instinctively grabbing his shoulders as she felt Abaddon slipping his tongue inside her mouth dominating the kiss completely. She meekly accepted his overbearing kiss and let out cute muffled moans into his mouth every once in a while.
She was breathless and huffing when Abaddon finally freed her lips that were glistening with the mix of his and her saliva, "Take care of yourself. I still have a lot of you left to violate." Akeno blushed at his words and looked down in embarrassment before casting the teleportation spell again, disappearing without answering.
Abaddon chuckled before looking out the window, seeing that it was dark out, "These two are probably going to be out for a while. Same with Sona and Tsubaki." Abaddon couldn't sense anyone in the house and decided to teleport to Xenovia, 'She's probably with everyone else, helping that new kid train.'
With a flash of yellow light, Abaddon disappeared and appeared in the middle of an empty ground. The first thing he heard was the sounds of Gasper's whining as he seemed to be subjected to something uncomfortable.
What came to Abaddon's view was Aika with a devious expression on her face, slipping a gimp mask on his obviously feminine face as he squirmed while twiddling his hands together.
"Of course, she does this," Abaddon mumbled with an 'as expected' expression, "Aika!" The pervert woman froze in place after having slipped the mask halfway onto Gasper's face.
"I can't see anything," Gasper tried to raise his hands up to the mask, but it seemed to be stuck to his face.
"Master…" Aika chuckled nervously, "What a surprise." Aika noticed Gasper's failed attempt and slapped his hand, making him put them back down.
"Senpai," Gasper called to her, but Aika just ignored him while looking at Abaddon nervously.
"Asia and Xenovia I can understand being clueless about it, but I thought you'd know better, Koneko?" Abaddon decided to deal with her later and looked at Koneko instead.
The white-haired girl looked spooked at Abaddon's abrupt words before looking down and making sad Nekomata noises, "I didn't see anything wrong with it, Senpai," She said, "Aika-senpai had a weird expression on her face, but it was just supposed to be a replacement for the paper bag…"
"Of course, you didn't see anything wrong with it" Abaddon sighed, "It's not your fault, It's my unruly pawn's fault." He looked at Aika with a stern expression.
"What else did you prepare?" Abaddon asked, expecting Aika to have prepared a lot more stuff to allow Gasper to thoroughly lean into his preferred role in life.
"Just this, master," Aika said, "I wanted to spook Rias-senpai and Akeno-senpai with the mask. I'm not into that stuff." She seemed to have understood what Abaddon was expecting her to have done and clearly defended herself, "And with master's presence, I could never even imagine thinking of anyone else in a weird way. I'm still dripping with your seme—"
Conjuring a ball gag in Aika's mouth to shut her up, Abaddon looked at her with a wry expression, "Don't sully Koneko and Asia's ears with your foul talk."
Aika moaned lewdly through the ball gag while rubbing her legs together. Her eyes had an expression of desire that he was intimately familiar with.
