Seraph was right, of course. The tingle of mana on her tongue was enough to make Pia reach out and grasp the altered feather in her mouth. It felt slick to her touch, and with her mana sight, she could see a faint glow as the liquid on it was smeared across the fingers stroking it. She was like a calf suckling a teat, or a girl with a pop sickle on a sunny day, eager to eke out every available drop of the precious liquid. Her hands stroked and caressed it, and her tongue and lips vere hard at work. She got her reward with every iota of power that disappeared down her throat.

While her mouth was busy, her nostrils were flaring as she drew in and exhaled, her breath matching the rhythm of the two other appendages embedded in her. Using her feet on the ground as leverage, she pushed her lower body of the floor, against each trust. Being taken in two holes made everything smug and tight, as if the sensations were not strong enough already.

Some of the power she had been taking in were being channelled back, her body's mana vibrating currents running down the three shafts and into Seraph, bringing with them a small taste of the pleasure Pia was feeling.

Seraph remained stationary as three of his feathers moved, a slight smile of amusement on his face. With Pia so blinded with mana and pleasure he didn't really have a reason to continue his act, well at least for the moment. He could simply play with her body, and watch her soul as it reacted to his efforts. He watched as one hand started to stroke the feather in her mouth as he felt her mouth and tongue working hard, trying to get as much of the liquid coating it as possible. He watched as she breathed through her nose, inhaling as the two feathers in her lower holes pushed forward and exhaling as they pulled out. The two other feathers fucking the blonde student's body also felt good, despite the fact that Seraph had only a weak sense of touch from his wings. The tightness of her holes, and the fact she was being taken in both at once, ensured that.

Suddenly Seraph felt a small tingle of pleasure run into him, and his slight smile grew a little bit broader as he recognised the source as being Pia's magic feeding some of her pleasure into him. Her feet were used to push her lower body against the ground, trying to increase the sensations. To make the feathers push into her faster. Now if that was what Pia wanted Seraph was all too happy to do his part in making the sensations she was feeling get that much more intense. The feathers fucking her ass and cunt both started to move a little faster, and each one grew a little bit larger as they moved back and forth, filling her holes even more and stretching her inner walls.

Pia accommodated the feathers easily, her body adjusting to take the increased force. She was twisting herself, offering herself up, almost daring Seraph to use her with as much vigour as he wished. Her openings were hers for the taking. It was almost as if she was pulsing, her inner muscles clenching and unclenching. She there to be taken, to be reamed and ravished.

"Mmmmmm..", Pia would sometimes pull at the feather fucking her face, almost out of her mouth, so she could let out her moans. It felt like she would burst if she didn't. But she would just as soon let it slide inside her, to explore her mouth as it wished. Her lips were glistening with spittle and the almost cum like lubricant of the feather. Pia's eyes were half closed, almost glazed, almost appearing drugged from the sensations overloading her, and the mana coursing through her system.

She was not used to handling mystic power, and certainly not in this amount. It was like every cell was vibrating with it. Was Pia a victim to be used, or some half-goddess of lust given offerings of pure sex instead of incense? She felt like both, or neither, and did not care about the difference.

Seraph watched Pia's body as it twisted around, offering itself to him as the feathers used all of her holes, with growing amusement. The reaction was amazing, and despite the fact he was only feeling minor physical pleasure the mental pleasure ... that was another question. Pia's soul was completely overwhelmed with pleasure and mana, a near maelstrom of colours and reactions to Seraph's soul sight. The entertainment he felt from watching that reaction was good on it's own, but with the physical pleasure he felt from his feathers using Pia's holes being reinforced by Pia's amateur magic trying to share the pleasure with him ... it all added up to an amazing feeling, of pleasure, entertainment, contentment. This student, and her lovely body, was his to fuck, to use, and if he wished it abuse.

As Seraph watched Pia let the feather in her mouth slide out so she could moan for a moment before welcoming it back inside her mouth, giving it free reign to move as it wished as she sucked, licked and stroked it. Seraph's smile grew slightly as he decided to use that freedom, that offer, to test something. All three feathers slid back until only the tip of each feather remained inside the hole it was using. Seraph waited for a moment to let anticipation build, before causing all three to push forward, snaking their way into Pia's body. Each one would go as deep as it could, trying to completely fill all three of the blonde student's tight passages, cunt, ass and throat.

Lets see how much you can take Pia. Lets find out just how welcoming you are.

"MMmmmm!"
Pia was protesting as the feathers withdrew. She was afraid that Seraph would withdraw altogether, leaving her just on the brink of another climax. She was twisting, and turning, as if egging him to take her.
Why is he pausing? Is it not good? Have I displeased him? Is he torturing me, bringing me to ecstasy, just to pull out? Will he leave me begging on the floor?

Then he issued a challenge. Very well. Pia would meet it! Even if she had been fucked so thoroughly she would normally have been a quivering mess. Hungrily, she watched Seraph. She shook her ass a little. The feather was still in her mouth, but instead of speaking with words, she formed her desire in her mind, a desire so strong that it made her mana vibrate with the words she formed in her head.

Take it! Take me! Take all of me! See how far you can bring me! FUCK ME!!!!!!

And then he rammed her, showed himself into her. Mana empowering her, she bent her legs, holding them up with her hands, almost paralell with her body. She was cumming again, another maddening climax. She gathered all the mana she could muster, as much pleasure as she could hold.
Then she channeled the force out through her cunt, her ass and her tongue, into the feathers, into Seraph, hoping she could bring him to feel even half the pleasure she was. Everything went white for a while, like a supernova.

EDIT: LAst post did not match yours. Sorry.

Seraph watched as Pia squirmed, her body trying to egg him on, trying to get him to drive into her tight warm holes. He could actually see flickers of fear growing inside her, fear at him stopping his use of her body. At least until his words, when she heard them that fear faded into determination. She was determined to meet his challenge, to push her own body to the limit. She shook her ass a little, a subtle sign that she was ready, and waiting. That was reinforced when he ... felt was the most accurate word, her mind crying out, the pleasure and mana combining to allow her to communicate with Seraph despite her mouth being around the tip of a feather.

Take it! Take me! Take all of me! See how far you can bring me! FUCK ME!!!!!!

And then the feathers moved, pushing quickly into each hole they filled her cunt, her ass, and her mouth. She lifted her legs until they were almost parallel with her body and used her arms to hold them in place as the feathers pushed. Each one would continue to move forward, the one in her mouth starting to enter her throat until her gag reflex forced it to withdraw, the one in her cunt until it slid into her womb, and the one in her ass until the tightness would prevent it from going any further. As all that happened Seraph felt a surge of pleasure flow up the three feathers and into his body, a portion of the sensations Pia was feeling. Teaching her the magic of a Voluptarius was definitely a good idea.

The three feathers pushed in until they could go no further, before pulling back and slamming in again. Trying to test her limits, to push them just that little bit further each time. They continued like that for a time, fucking Pia's holes roughly, and with the blonde's body supercharged with mana she continued to respond, to remain fully aware. Seraph could see Pia's soul completely blasted by the pleasure, and smiled to himself.

When he finally relented each of the feathers withdrew from the hole it had been violating, forming back into their 'wing' form as Seraph stood over Pia's body. He waited for the sensations to die down, and for her awareness to return. When that had occurred, something that took several minutes, he asked Would you be interested in me cumming inside you again Pia?

Pia slowly came down from her high. The world was slightly pink, and it felt like she was floating, the world only slowly coming into focus. She could feel that she had been taken hard and deep, it was like the ghost of the tentacles still were inside her, filling her up. She dimly suspected that normally, she would have been in pain now, but it seemed the mana bolstered her body, made it adapt to not only take it, but enjoy it as well.

She was showing signs of exhaustion, though. She was glistening with sweat, and deep down she knew that when this was over, she would drop into sleep and stay there for the day and the rest. Not now though.

Would you be interested in me cumming inside you again Pia?

Pia slowly rose to her knees. She was a bit wobbly, swaying slightly, but determined to keep doing her best. She looked at Seraph with her mouth half open. She ran her tongue over her soft, glistening lips, sampling a little of the liquid the feather had deposited. Looking up at Seraph, she said "Yes. Please do. Please let me receive you.. once more."

She reached forward and touched his manhood with her hand. "How do you want me?". She honestly had no idea if she would be able to take another dose of his cum, but somehow her mind was so focused on sex that no did not occur to her as an option.

Seraph watched as Pia slowly raised to her knees, her body wobbling slightly as she swayed from side to side. Even with the mana fuelling her body her mind was starting to become overwhelmed by the sensations. Of the hard fucking she had received, and of the mana storm that raged inside her body. And yet she forced herself to move, her tongue licked across her lips, sampling some of the mana rich liquid that had coated the feather that had been inside her mouth.

"Yes. Please do. Please let me receive you.. once more."

Seraph smiled as Pia reached forward and touched his manhood with her hand. "How do you want me?" she asked, her body and mind responding instantly and unthinkingly without knowing if she could actually handle him taking her once more. Seraph considered as her fingers gently touched his cock, weighing up the possibilities. It only took a few seconds to decide how he wanted to take her, and Seraph ordered Turn around and stay on your hands and knees Pia.

He waited for her to comply, and when she had he moved behind her and dropped to his own knees, sliding behind her and between her legs. The head of his cock rubbed against her cunt, teasing her with it as Seraph admired her cute body. He continued to tease Pia's body, the head of his shaft quickly becoming coated in her juices. After what probably felt like an age to Pia he pushed forward with his hips, sliding slowly into her tight soaked cunt for what would probably be the last time tonight.

Pia wasted no time in assuming the position. She was there, on all fours, ready to take all Seraph had to give. She made sure she was a pleasing sight, arching her back a little, casting an expectant glance at Seraph across her shoulder. Much of her hair had escaped from the buns she had tied them up in, framing her features, making her face both seem softer, rounder, yet wilder.
Her lips were glistening, appearing softer, fuller and redder, perhaps she had unwittingly made them seems so, in response to her need to be desired. Her being radieted the image of a willing, naughty schoolgirl, ready for her teacher to be given the fuck she deserved so well. It was a simple manipulation, one she had no idea she was using, simply boosting an image of her that might be appealing.

She groaned impatiently as Seraph teased her cunt. It was wet, warm, burning, and he must know by now how tight it was. Why don't he take me!, Pia's mind screamed. Yet the infuriating desire was a kind of pleasure in itself. A lesson the aspiring voluptarious would do well to heed, sometimes the arousal is as good as the fullfillment.

And then she got her reward. Slowly, the large cock entered her. Slowly, but firmly, he sank into her, strong hands on her round butt, making her his. Pia's mouth was a circle. she was taking in air, then releasing a moan of contentment. Her body had been ravishes so thoroughly, it should have had little to give her without some rest, but still she felt pleasure, absorbing the sensations and pleasure of the angel behind her. She did not care if he took her hard or slow, as long as he, and hence she, took pleasure in it.

Seraph had to praise Pia's use of her magic, even if she didn't really understand how she was doing it. The massive amount of mana in the air, and inside her body and soul , allowed her body to experiment to maximise her own pleasure. In doing so it also maximised the amplification of her own abilities. Her appearance was a subtle influence, something to make her appear something to draw anyone into sex. It was only an illusion, Pia didn't have anywhere near the skill required to do a full shape-shift. But it was a coherent illusion and one with no flaws. Even now part of his mind was still working, assessing her growing potential as her natural talent unfurled. While it would be a while before Pia could cast any of the spells she could cast near Seraph, or willingly cast such spells, the fact that she could now told Seraph much about her potential. Pia had a natural power, all she would have to do was learn to throw herself into her studies, to overcome her shyness and embrace her own particular gift of magic. And if Seraph could teach her well enough ... she could very well make some of the aliens who preyed on humans suffer for their lusts. Despite everything Seraph still saw himself as an ally of humanity, and generally opposed to the various beings that raped them. He couldn't leave Shokushu at risk of his escape being noticed, and as such abided by the rules that allowed him to remain here with minimal fuss. He left the other monsters alone, and generally they did the same to him.

But even as part of his mind assessed Pia's magical talent the majority of it was focused on enjoying her cute body as he moved behind her, his shaft filling her slick cunt as he pushed slowly into her. His hands gripped her smooth rear, holding her in place as he pushed and her folds opened up before his thick shaft. He took it slow, for the moment at least, marvelling in the way she gripped his shaft inside her. He let her feel every inch as he slowly slid deeper and deeper, his fingers and hands starting to lightly squeeze her rear cheeks. Soon his hips met her body, and with his shaft fully lodged inside her he started to pull out. He moved at the same slow pace as he pulled out, and when he finally had only the tip of his shaft left inside Pia's cunt he paused. After a moment's hesitation he pushed forward with his hips, plunging his cock deep into the blonde student's body in a single smooth movement.

"Ahhh.. Y-yes..", Pia moaned. "Take me.. I love your big, throbbing cock in my tight cunt." She was gasping and squirming a little with excitement as Seraph buried his member inside her, sheathed himself in her wet, welcoming folds. Her full breast swayed a little back and forth, and she thrust her bottom back against him, to help him get deeper.
She wanted him hard inside her, she wanted him to take her like an animal. She wanted him to read the treasure of her body.

Even though she was physically exhausted, she still imagined him bending her over the desk, mounting her, taking her while she kicked her legs with each thrust. She tried to imagine herself as he must see her, skirt framing her exposed butt, her body his to take.

As Seraph plunged into Pia she cried out, her words underlined by a moan of pleasure. Her body squirmed from the excitment of Seraph burying his cock in her tight sheathe, and she was gasping for the exact same reason. Her breasts swayed back and forth slightly as she thrusted back with her rear, pushing him deeper inside her faster. Seraph smiled at that, and at the images he ... felt would be the most accurate word, in the mana that was surging around her. Her mind was focused on something, and while the change itself was far too great for her skills to acomplish, even supercharged with mana, it did allow Seraph to see what se wanted, to see just how she wanted to be taken.

A vision Seraph was all too happy to put into reality. He suddenly pulled out of Pia and his hands released her rear cheeks. Before she could complain his hands grabbed her by the middle and effortlessly he rose and walked towards the nearby desk, carrying Pia in front of him with no apparant effort. When he reached the desk he positioned her exactly how she had imagined it, and he plunged into her cunt again with his cock. He pulled back and thrusted a few more times before suddenly pulling out and just teasing her with the head. How about you beg for me to take you in a certain way Pia? He suggested.

Pia squealed a little as she was picked up and placed on the table. Her mind raced. She had been thinking of this, and either she must have motivated him to do so, or he must have read her thoughts.
She was not about to get too philosophical about this, though, as Seraph wasted no time in taking advantage of her position.

"Ah-AHHHH!". Pia screamed as he slammed into her. He gave her a few more powerful strokes. Pia grabbed hold of the desk to brace herself, and had her sneakers on the ground, but standing tiptoe to offer him more of her rear. Just as she was about to abandon herself completely, he withdrew. The tip of his penis was teasing her opening, making her shiver with lust and anticipation.

He wanted her to beg. She was about ready to do so. "Please.." she said, almost moaning as she spoke. "I am begging you.. take me! I just want to be taken once more. Just once more! I will be good.. just grab me, grab my hair if you like. Just ream me until you come! Come inside me, if you will, or spill it one me. Take any opening you want.. Just.. pleeease!"

She moved her rear a little as she spoke, to tease herself and him by moving her wet pussy against his cockhead.

Seraph watched as Pia instantly responded to his thrust, her hands gripping the table as she stood on tiptoes, presenting as much of her rear to him as possible as she screamed in pleasure. Just before she was about to lose herself completely to the pleasure Seraph stopped, and when he asked her to beg she almost instantly complied. At her words Seraph chuckled briefly, liking both the way she was speaking and the sensation of her slick lips rubbing against him, teasing them both.

Seraph reached out and each of his hands closed around one of Pia's buns of hair, taking up her offer of letting him grab whatever part of her body he wished. His hips shifted as he used her hair to pull Pia's head back, and the head of his cock prodded against her ass. Seraph pulled on one of Pia's buns, forcing her head to turn to look at him through the corner of her eye as he started to speak. When you ask like that how can I refuse you? Seraph let Pia see his smile before his other hand pulled, making her look directly away from him as he slowly pushed his way into the blonde student's tight ass, filling her rear inch by inch.

Having her hair grabbed and her head forcefully turned was painful, but nothing Pia could not handle. If nothing else, it enhanced her overall sensitivity, heightened the feeling of being taken, as Seraph forced his cock into her ass.

Be is so big and forceful, and I am so.. tiny.
"Ohh..ahh-mmmmmm!", Pia made mewling, moaning sounds as he sank into her, sound that turned more passionate as he filled her up, and her tight entrance accommodate him. "Ohhh, yes! Ah-AAAAHH!"

Anal sex was not something new to Pia, she had been used in every rifice before. Seraph had even taken her that way by means of his feather before. Yet the act had some special meaning in Pia's head, some symbolic value she could not explain. It was taboo, but in a way that just made it more exciting. That she had dared to even suggest so herself was evidence of how high she was on magic. Otherwise even suggesting it would have made her acutely embarrassed, now she was begging for it!

With her bent over the table, Seraph's grip on her hair and Pia speared by his mighty member, she was completely at his mercy. She was his to take, to ride until he had had his fill.
