This went on for the rest of the two minutes as just as the time was finished, he pulled back from her face. "Time up." He said and stepped back.
"Please…" She begged as she pulled her face forward, looking for his cock. He slapped her bare breast leaving a visible red mark, "What are you supposed to say?"
"Please, sir…" She begged after whimpering from the pain of the slap. "Get through the barrier and you'll get it." He said before forming a more complicated magic circle in front of her face, still in her tongue's reach. This one's more complicated and larger. "Break through this and this time You'll get me for 10 minutes." He set an ultimatum while moving out of the room, giving her time to break through it.
As he stepped out of the time-dilated zone, he left the door open so that he could see her progress. It was as if he was watching something at 60 times the speed as she licked around the circle. Within 30 seconds on the outside, she was done.
'30 minutes… She's getting good…' The thing was that the process of breaking through these barriers wasn't as simple as just pressing a specific spot. She had to move her tongue in a specific manner if she wanted to actually break through the barrier. The lines that comprise the circle had to be touched in a specific pattern so that they would unravel. This was why her act of being able to break through this circle in just 30 minutes was extremely impressive. This couldn't just be done by randomly fumbling around. She had to understand the structure of the weaving of the lines as she licked around.
'The biggest thing is that she's blindfolded and working only based on her memory, commendable.' He was impressed by her.
Just as the circle dissipated, he entered the room's time dilation zone and said to her before she could say anything, "Good job. If you can make me cum in these 10 minutes, then I'll give you a little surprise." He said to her, moving in front of her face. His cock was still erect and free as it glistened with her saliva.
"Thank you, sir…" She said before starting her work on his cock. Bringing her face under his cock, she sucked his balls into her mouth and played with them using her tongue for a while before moving to his shaft.
She used all of the tricks that she had on his shaft as she practically worshipped it with her mouth. Some of those tricks even made him groan with pleasure.
Soon, the 10 minutes were about to be up and he was feeling like he was close. Deciding to give her a reward, he said, "I'm cumming, Aika." He said as suddenly, his cum shot out of his cock and sprayed the back of Aika's throat.
She tried her best to take it all, but she wasn't experienced with a real cock and wasn't able to take it all in, causing some of it to escape down the side of her mouth, making her face look very erotic.
He'd also laced his cum with a nice dose of his dilated Power of Destruction and as it went into her stomach and was digested, her body would be empowered enough to let her sustain herself for the whole of the 60 hours that they spend here.
Just as he pulled his cock out of her mouth, Aika was like a puppet that had its strings cut off and went limp in her chair while wheezing heavily.
"You deserve a reward, my Aika…" He said with a gentle voice as he went over to some of her other toys and grabbed a pill vibe along with more coils of rope. "Such a naughty girl with so many lewd toys…" He commented as he walked back to her.
Grabbing her leg, he pulled it up and tied her knee to the armrest of the chair before repeating the process with her other knee, making her spread her legs in an M shape revealing her panties completely, "Pink, how cute…" He chuckled and saw her blush for a whole different reason. Though her natural submissiveness was enough to drown out any semblance of protest she might have been feeling.
After tying her legs in that position, he slipped his hand into her drenched panties and ran his finger over her gushing slit before grabbing the pill vibe and placing it just above the slit, over her clit where it would have the best effect.
"Break through the barrier again and you get more time with my cock." He told her before casting an even more complex circle that would change its patterns in a set manner and this time, the circle was even larger as it surrounded the whole area of her face. She would have to use her tongue to navigate around the surface of the circle and also move it around. Leaving her to figure it out, he turned on the pill vibe and heard her moan with a struggle. But the chair was heavy enough and didn't let her do anything. All she could do was extend her tongue and try to understand the complexity of the magic circle.
Sadly for her, the vibration from the pill was far from being enough to make her cum, 'I mean I am a devil, we don't really do kindness…'
Meanwhile, he decided to move out of the room again and observe her.
After a minute, he was surprised by her again, "Just an hour?" He said with disbelief lacing his tone as he expected her to take at least 10 hours to finish up, 'Could it be a fluke?' He thought as he decided to cheat and reestablished the circle with a different randomizer of patterns.
45 seconds (minutes) later, she was done, "She's a bloody genius…" He was impressed. She kept learning and getting better with each subsequent task.
He came back to her and let her worship his cock again as he subtly increased the intensity of the pill vibe. Seemingly having lost track of herself and the time, she sucked him off with gusto as she wanted to milk the heavenly substance out of him again. Apparently, the devil's cum was very appealing to her, 'Or could it be humans, in general, that love the taste of our juices…' He thought absently as he enjoyed Aika's talented tongue working her magic.
After a while, she was given her reward as she slurped his semen with gusto, this time, not even wasting a drop, he'd even made the pill vibe work in tandem in a way that she climaxed with a shudder just as he dropped his load down her throat. He decided to infuse even more energy into his semen as he saw her working so well. Also because he was going to give her a barrier that was going to be even more difficult and it was bound to take time even with her insane talent.
He cast another circle, this one being a real barrier instead of just being a magic circle with its 'circuitry' exposed. As he cast the magic, a small translucent dome formed around her head. She would have to understand the structure of this barrier with a lot of effort as there were no lines for her to follow anymore. He allowed the barrier to be rotated around by using her tongue as it would become impossible for her to work it otherwise.
Leaving the pill vibe at a weak intensity so that she would be hot and bothered but far from being enough to let her cum again, he walked out of the room.
As he walked out of the dilated barrier, he observed her efforts as he rested on a random chair.
10 minutes later, she was done. "You really don't cease to impress me do you, girl?" He said as he walked into the room, back to the time-dilated zone. 10 hours to unravel such a barrier while still being blindfolded was nothing short of a miracle.
"Thank you for the praise, sir… Will you please allow me to suck your cock again?" She asked.
…
That was how her training went for the whole 60 hours. She was able to break through the basic barriers within around 5 hours using just her tongue and nothing more. reducing her time from the previous 10 to five was also a feat in and of itself.
When the time was up, the dilation naturally dissipated. Aika was still sucking him off with gusto as that happened. After he unloaded into her mouth again, he pulled away from her face and cast a cleaning spell on himself before pulling his pants up.
She was still tied up on the chair as she her head limply hung at the side while she breathed short breaths, her legs still stuck in the M shape as her panties were drenched and a puddle of her liquids had formed under her.
He brought another chair and sat in front of her before pulling off her blindfold.
