The grip Seraph had on Pia's hair would be painful, but by the very act of being painful it would enhance the sensations of pleasure Pia could feel from Seraph fucking her. After all, pleasure and pain were the same sensation, with the only difference between the two being intensity. That was a fact Seraph knew, and one that Pia would have to learn to become a fully fledged Voluptarius. She would either have to work it out herself, or Seraph would have to teach her, most likely through demonstration. The prospect was a entertaining one to think about, and just imagining that particular lesson made Seraph want to take Pia hard. To use and abuse her lush body, her tight ass. He managed to refrain from doing so, but only just.

Slowly Seraph forced inch after inch of his thick shaft into Pia's tight rear passage. His cock spread her rear wide open, filling her completly as he pushed in. She cried out in pleasure as he moved deeper into her tight passage, her cries rapidly becoming more intense. Soon enough Seraph found himself fully lodged in her ass, and he started to pull back. His movements were slow, but each time he shifted direction he would move a little bit faster than the last, pushing in or pulling out faster and faster as he used her hair to hold her head up and back while he started to use her rear passage to pleasure himself.

You like being taken like this ... don't you Pia?

Pia was breathing heavily. Cock out. Pulling in air. Cock in, letting breath out with an intense moan. Her ass was quite sensitive, she had learned, both a blessing and a curse. But she could take it, she knew. She could take it all. The large member in her narrow canal made all feel so tight, like all was pushed together. And with the mana coursing through them, the pleasure he was feeling was spilling over into her.

"Yes..", she groaned. "I like it when you.. AAHH!.. take me like that!". She clenched the muscles in her buttocks a little, as if to egg him on a bit more.
"I--aahh- like it when fuck me like this.."

Pia's tight ass felt amazing as the fallen angel pushed his shaft inside her rear, tight sensitive walls being spread wide by his bulk as she moaned. Each time Seraph pushed in Pia let out another passion filled moan, only being able to draw breath when he pulled out. It was almost as if Seraph's cock was now controlling the blonde haired student's lungs. That feeling of control was almost intoxicating, and was certainly addictive. Seraph started thrusting harder into Pia's ass as the pleasure he felt, both physical and emotional, grew and grew.

When Pia replied to his question, admitted that she liked being taken like this, Seraph felt himself smiling. The muscles in her rear clenched tighter a little, trying to egg him on and intensify the sensations the two felt. Seraph was only to happy to use her even harder, and the speed and force of his thrusts increased yet again. If it wasn't for the massive amount of mana Pia was using to augment her body this would undoubtedly be painful for her. But Pia was using that mana, and so all she would feel from it was unbelievable ecstasy.

You ... feel ... divine ... Pia ... You ... look ... divine. Seraph grunted as he pounded away against Pia's body, praising her. He wasn't sure if she would notice, or even care, about his praise. But he did feel it was something he had to say.

Pia felt divine, too. It was like she was at once herself, normal Pia with a physical body, and something else, a conduit for power much greater than herself. Without knowing it, her mind was sort of drifting beyond and outside her body.

Partly, she was there, being taken roughly from behind, feeling her ass being ravished, her pussy grinding up against the hard wood of the desk. Her voice was getting more intense, more high pitched with every thrust. She probably wouldn't be able to sit properly for a while, but she was too far gone to even care.

But it was also like she was a spectator to the scene. Pia did not know if it was just a trick of her mana drunk mind, or if she was really experiencing some out of body experience. It was like she was watching Seraph as he fucked her. Watched his strong back and the luxurious feathers of his wings, watching how his strong buttocks moved as he worked her over, harder and faster, like an engine picking up pace. Pia watched herself, partly undressed. She was kicking her legs now, in response with each trust. Legs partly covered by her longs socks moving along Seraph's legs, her sneakers slamming against his buttocks each time he rammed into her.

Pia could also see the interplay of mana, how both her and Seraph's bodies were pulsing with his light.

Seraph's smile remained as he felt Pia's stocking covered legs slide up his body and wrap themselves around him, her sneakers pressing into his back as he continued to slam into her ass, pulling her body against him and letting his thick long shaft pound into her tight rear even harder. She felt good, and the way her soul pulsed with her own desire and pleasure as his mana entwined with her soul was amazing to watch. A whirlwind of light, pleasure, lust, and life. The two sensations combined, the physical sensation of pushing his cock into something so tight, and the mental sensation from watching such a display. She was definitely a natural Voluptarius, and definitely something that was worth all the effort Seraph had put into manipulating her earlier.

Even as Seraph continued to pound against Pia's body he decided to make things even more intense for her. With every thrust he made he pressed her cunt against the rough wood of the desk. Deciding to use that Seraph cast a quick spell that reshaped the part of the desk Pia's slit was rubbing against. The wooden desk suddenly grew a series of small rounded raised sections, and each time Seraph's thrust forced Pia's body against the wood those raised sections of wood rubbed harder against Pia's cunt.

I think you have been a very naughty girl Pia, and you definitely need to be punished more. Seraph spoke when he decided to feed the fantasy that had sparked this position, that of Pia being a naughty schoolgirl and Seraph the teacher who was in charge of disciplining her, his cock still pounding into Pia's ass.

The table changed beneath her. Normally, a display of such obviously supernatural power would either scare Pia, or awaken her curiosity. Now she just accepted the new sensation it offered her. The feeling of small, smooth bumps and ridges that her cunt was rubbed up against. The hard wood was moist with the juices of Pia. Her body moved rhythmically, her whole being like one breath perfectly paced with Seraph's thrusts. Her buttock were clenching and unclenching, adding more pressure as Seraph sank into her, giving him a little more resistance to work against.

Yeah, I have been bad. Pia said. Or thought. She did not know. Give it to me, give it to me like you know you want it. Most of Pia's being was a riot of mana and sensations, lust and power, her will subsumed by the force of fucking. Yet she was not totally gone. She knew she would need to come, to reach a peak in order to rest, and that she needed something to push it over the edge.
Punish me! Don't you want to punish me? Spank my ass! Slap it! It is waiting for it!
Without her knowing it, Pia's mana reverberated with her lusts and thoughts, making a teasing, egging little song of it.

Yeah, I have been bad. Give it to me, give it to me like you know you want it. Punish me! Don't you want to punish me? Spank my ass! Slap it! It is waiting for it!

Seraph could hear Pia's thoughts, could feel them echoing through the mana surging around the room, their sweet seductivness rolling across his skin as she poured all of her energy into egging him on. That's exactly right Pia. That is the first stage of becoming a Voluptarius. To take some form of control during a situation like this. Seraph praised her for a moment before letting his body act as she wanted it. He shifted the grip on Pia's hair, holding both of her buns in one hand as the other reached back.

The next time Seraph thrusted his hips forward his hand came down. The moment his cock was as deep inside Pia's tight ass as it could go the hand spanked her rear cheek. He did it again, and again, always matching his timing. It didn't take long for Pia to finally orgasm again, and as she did Seraph thrust deeply into her and let his own seed out inside her ass, no doubt ensuring that he overwhelmed anything left of her mind.

"Aaah-aah-aah", Pia moaned, fast little bursts of her voice in time with the slaps against her ass. Each little burst of pain, contrast to the pleasure soaking her, sharpened her senses and brought her closer to the peak. With something like a wail of pleasure, she came, like a cart on a roller-coaster brought to the top, and then starting its rush downwards.

And then Seraph spilled his seed inside her, cum splashing against the insides of her ass. The mana rushed through her, and the metaphorical roller-coaster ride just broke the wall of sound. Or of light. Pia's mind was like scene from 2001: A space Odyssey.

And then everything became white. And then, oblivion. Pia did not fight it. Deep down she knew it was better to let physical and mental exhaustion take her now, while she was on top of her high, than to experience the inevitable cruel rush back to reality.

Her mana sand a pure note, reverberating through the walls of the basement well past the point of unconsciousness.

Seraph smiled slightly to himself as Pia's Soul, as expected, was completely overwhelmed by both her orgasm and his mana rich cum pouring into her body and soul yet again. Her orgasm was far more intense than anything she had previous experienced, and it was at the peak of such intense bliss that her awareness faded and her soul slipped into unconsciousness. If it wasn't for the sheer intensity of Seraph's mana she could very well have died from the sheer sensation, her entire body excited beyond it's ability to cope. But Seraph's mana had given her body and soul more than enough energy to survive, even something as powerful as what he had just done.

Seraph pulled himself out of Pia's abused ass and a gesture from his hand returned the room to the state it had been before Pia had arrived, well except for the Darklight Grimore which he recovered. He looked around once and nodded, Pia held in his arms as a thought teleported the two of them back to her dorm room. He placed her on the bed, a hand brushing over her healing what his use of her had done to her body, and gently tucked her in, a smirk on his lips. He returned to his garden ... but not before casting a subtle dream spell on the blonde haired Pia, and another spell to ensure she would not be missed no matter how long she slept. She could skip the entire next day and every single record, student and teacher would say she had been at all her classes acting exactly the way she normally acted.

When her mind had recovered enough to have dreams she would find herself lying on a field of soft grass stretching out as far as the eye could see. Seraph sat near her, his wings wrapped tightly around himself as he faced away from her. He spoke, not turning around as he did so. When he did it sounded like Seraph's voice, but something about it was different. A slight change of tone, a little more emotion and intensity behind the words.

Pia ... No doubt you will try to avoid using the magic you were just taught the basics of ... you will feel bad about what you could very well call 'giving in'. But practice it whenever you can. I will not lie, if you practice it you will become a more appetising target for the monsters here as word spreads that you are a great student to take. But that in itself is a lesser sacrifice of the now, and one that will pay off in the future. If you take any chance you can to practice, you should be more than powerful enough by the time you are sent to the sex slave pits off world to escape, probably even return home. But to reach that you have to make a decision now to practice your magic whenever you can, and on any partner you have for sex, be they human or not.

Pia's dream self sat on the geen field. She did not verbally answer Seraph, merely nodded her head to acknowledge his words. Somehow, she felt he would get that, even if he was not watching her.

Here, in this calm landscape, she did realize that her behaviour had not been her at her usual self. She had been affected by the power involved. The mana had made her drunk, high, made her act like she normally wouldn't. It was not the first time. She had been the target of drugs and aphrodisiacs before, even telepathic powers.

She also knew that even if she had been with her full senses, she would have done it all anyway.

Pia had realized her fate. She was nothing but a slave and a whore now, all but waiting for the moment when they would came for her the final time. She would be carried off. NO doubt her captors would have their little fun with her first, then she would be shipped off. Pia had some rough ideas about what would happen to her after that. She did not think she would last long.

Being a Voluptarius might change that for her. Besides, it felt right, somehow. There was something inside her that wanted pleasure, wanted the power of sex and lust. Sex had so far been something used against her, so rarely had she been able to enjoy it freely. Maybe now she would master it, be able to enjoy it fully, instead of being someone's fuck doll, to be grabbed, filled with cum and tossed aside.

Pia smiled a little. There was a touch of irony here. Shy, awkward Pia had the talent of a sex mage. Good to know that not all privileges are reserved for the beautiful, long legged and confident ones. So it goes.

In the physical world, Pia slept like a gently snoring rock. The sun would rise, pass the heavens, disappear, and rise again and kiss its summit again before she rose. She would be hungry. After weeks of half-eaten boxes of yoghurt and mugs of coffee going stale, her appetite had returned.
