Pia smiled when she heard the reassuring voice. She was eager not to dissapoint. Seraph had been generous to allow her to train with him, and this was for her own good. She needed it, she knew.

Pia spared a few seconds to again admire the angel. Physically, he was close to what many would consider perfect. And he seemed to respond to her caresses, his cock growing larger and firmer.

Feeling braver, Pia gave it a go. Instead of just taking it in her mouth, she continued to stroke it with her hand on one side, and let her tongue trail along the other side of the shaft, down, up, down and up again. Hoping Seraph enjoyed it so far, she cupped his testes with the other hand, and gave the unerside of his member the same tongue treatment.

So far, so good..

Pia placed her little mouth on the cockhead, and swallowed a few times to lower the pressure in her mouth. She then pushed her head gently forward, feeling the head slide against her tongue as it entered her mouth.

Seraph couldn't help but smile at the naive and innocent Pia as she tried to give pleasure to him. Her hands and tongue worked gently together, trying to please him. There was something about her innocent touch that made them somehow even better than the most experienced student's here, despite the difference in technique and confidence. Maybe that was the reason, that knowledge that Seraph was dealing with something innocent and unexploited. A rare thing here, most of the student's first encounters had been with other monsters that Seraph was forced to share the student body with. Well at least when he was not using a particular student he was.

His cock had continued to respond to her fingers and tongue as they moved around, Seraph focused on Pia's mind for a moment as he used a mind reading spell to determine just what size she figured would be best. He didn't want to frighten her off by her thinking he was too big after all. That would also give the entire deception away, and that would be a whole lot of wasted effort. So Seraph simply kept up his deception of being as perfect as possible. It was the safest, and in the long term most entertaining, way.

The moment Pia's lips pressed against his cock Seraph felt a flare of satisfaction. As her mouth started to gently slide forward he let a small amount of his mana rich pre-cum seep from his tip. The liquid was sweet tasting, and it caused a weak surge of energy to flow through Pia's body, invigorating her. It also made her crave more of the liquid mana, the mana addiction quickly setting in.

That's it. Your doing very well Pia. Seraph praised her vocally, encouraging her to continue and improving her self confidence in her ability to preform such a task.

Pia lapped up the praise. She could not help it. Pia was always eager to please those that showed her kindness. Since Seraph seemed to like what she was doing, she decided to continue with more energy.

She altered her technique a little. Trying to work up some spittle in order to make thing smoother and more comfortable for Seraph, she hoped. She then trust her head forward, opening her jaws so she would not scrape him with her teeth, but still keep her lips tight on the firm shaft. She took in as much of his rod as was comfortable, then withdrew and thrust her head down again, faster this time. She glanced up at him with her big blue eyes, looking for signs of approval.

The taste of his precum seemed different from much of the liquids she had previously been forced to swallow, it felt invigorating, fueled her desire and her senses. It must be the mana, she realized. The powerful drought fueled her lust, made her clit tingle and her cunt get even wetter. Her panties were moist, soggy. She did not want them anymore!

But now her horniness had a focus. Gradually, she picked up the pace. Her blond head was bobbing up and down as she abandoned herself to the task at hand, giving her generous teacher the headfuck he deserved!

Seraph continued to smile warmly down at Pia as her head started to bob up and down, her mouth sliding along his shaft. He looked into the blonde'e haired student's blue eyes as they look up at him. He could see the desire for approval there, and he was all too happy to oblige, considering the warm sensation that was spreading through his body from her mouth sucking on his shaft. Your doing well Pia. Good girl. Seraph's voice was warm as he praised her blow job. It was also honest, unlike a lot of what Seraph had told Pia, either directly or indirectly.

Seraph reached out and started to gently pat Pia's head as she continued to move faster and faster, her head bobing up and down on top of his shaft as she eagerly poured her focus into the blow job she was giving him. She was doing an amazing job, Seraph was quite impressed by the sensations she was able to create. She made up for lack of skill with innocence, and genuine commitment to what she was doing. Seraph set up a new control over his pre-cum, and it wouldn't take Pia to realise that the faster she moved, and the deeper she took him in her mouth, the more of the addictive, sweet and invigorating liquid she would get.

Of course this wasn't just about giving him pleasure, and giving her more than the simple pleasure of being in direct contact with such potent mana. With a thought one of Seraph's wings seperated into it's 'feathers', and one of the enwly formed feathers of light slipped down underneath the kneeling Pia and started rubbing against her drenched panties, pushing the fabric along her very wet slit.

"Ahhh.. oh yes! Please.. it feels so wonderful!"
Pia temporarily let her mouth off the erect penis as she felt something soft move against her eager little bud, sending shivers up her spine, even with the panties between them.

She did not stop for long. Partly because she feared displeasing her kind benefactor, but also because a drop of mana charged cum slid down her throat, causing a riot of sensations inside her. She once again applied her head to the task, with even more enthusiasm and greed. The cock was so big, so.. powerful. And it seemed to throb with power, at least it seemed so to Pia's mind, which conjured up images of magic enriched semen pouring into her, filling her with sparkling power.

Her lips, her hand and her tongue worked in tandem and her head moved up and down. Sometimes she would pause with her lips on the cockhead, circling it with her little dexterous tongue. During one of her pauses, she risked putting her free hand beneath her, yanking her panties down to allow better access to her sex.

Seraph couldn't help but smile at Pia as she cried out, and as she hungerly used her mouth, tongue and hand on his shaft, trying to coax as much out of it as she could. The addiction had firmly taken root inside her, and drove her to seek more mana. But the more she sought, the more that addiction craved it. A self repeating cycle that Seraph had used so many times here to his advantage. And he knew that he would use it again. It worked far to well to not use it, if something wasn't broke why would you try to fix it?

But of course Pia soon proved that the addiction wasn't the only thing driving her. During one of her brief pauses where she stopped sucking him off so she could run her tongue around the sensitive head of his cock, her lips paused on the edge, her free hand slipped down under her and pulled her panties down, exposing her dripping cunt to Seraph's feather. It wasted no time in taking advantage of this newly exposed area and soon the smooth 'feather' was rubbing against Pia's cunt. It did that a few more times before Seraph murmered, loud enough so that Pia could hear.

Since you are sucking on me it's only fair that I direct something to suck on you.

Pia would have about a second to work out what he meant by that before the bell shaped tip of the feather latched on to her clit and started to gently suck on it. For the moment Seraph kept the inside surface smooth, although that would change soon enough.

Pia had no idea what Seraph meant, and there was no way she was going to turn around and look, and abandon the taske given her.
She felt it soon enough anyaway, as something touched her nub, and started to suck on it. It was a wondrful feeling, her bud being taken into.. whatever it was that was touching her and sucked.

"Ooohhhhh..", she sighed contetly, giving her a small respite from felating her teacher, and instead letting her mought and tongue trail down the glistening shaft. At the same time she stroked it with her hand, gently pressing it against her face. She licked the lower side of the shaft harder, then but her mouth gently against his testes.

"I-I d-don't know what you are doing, but please, please keep it up..", she more sighed than spoke.

Seraph watched Pia's confusion for the second he gave her to work out what his words meant before that confusion faded into bliss. The bell's suction easily enough to cause her to not care what was giving that sensation, only that it continued. For a moment it even caused her to stop pleasing Seraph's cock, although that moment quickly faded. She didn't take him back into her mouth, instead her mouth and tongue trailed down the side of his shaft, her saliva enough to make it glisten in the light. Her hand contineud to work it as she slipped her mouth lower and lower, eventually ending with it pressed against his balls.

As I said as long as you are sucking on me it's only fair that I have something sucking on you. Seraph repeated his earlier statement, letting Pia know that the more pleasure she gave him with her mouth the more intense the sensations she would feel from the bell sucking on her clit. As an example Seraph caused a tiny tendril to form inside the bell and it started rubbing across her nub as the suction drew it out. If Pia did well Seraph would make more tendril's form until the interior of the bell had hundreds of them, all of them rubbing and flicking across Pia's sensitive nub and by doing so probably driving her insane with pleasure. But that was for later, for now she just got the one.

"Mmmmmm-that's-ahhhhhhh!".
Pia nearly squeeled with delight as her clit was not only being sucked and massaged, but also tickled and teased. She shivered visibly, and almost feel over.
She got the point. The better she worked the cock, the more Seraph would reward her.

So she took the cock in her hands and stroked it, and give it a tiny, harmless slap, as if to test its hardness. She then took it into her mouth, as far as she could, suckling at it like a calf at its mother's teat. She might be inexperienced and shy, but the promise of more pleasure, and more of Seraph's powerful mana cum, made her loose her inhibitions.

Her vaginal muscles clenched a little. The mana flowing in her body had worked like foreplay, and now her body was reaping the effects of physical stimulation as well.

Seraph smiled at Pia's cry of pleasure and he watched as her body shivered and almost lost it's balance. She recovered quickly, and almost instantly resumed her attempts to pleasure him. Her hands started stroking his cock, and after a brief amount of time one gave it a very light slap, too light to cause any discomfort. Seraph felt wave after wave of pleasure flow into him from her hands, and when her hands stopped stroking it and she instead took it as deep into her mouth as he could those waves become a flood of pleasure. Seraph could feel Pia sucking on him as his shaft filled her mouth, the tip pressing against the entrance to her throat.

Pia seemed to have overcome her earlier shyness and inexperience, and since her warm mouth suckling on his cock was giving Seraph so much pleasure he decided to return the favour somewhat. The bell that was latched onto Pia's clit suddenly extended dozens of tiny tendrils towards the sensitive nub. In seconds the entire surface of the nub was being flicked or rubbed by tiny threads of light, all the while suction continued to draw it out.In addition to the bell's changes Seraph also increased the amount of mana rich pre-cum that was seeping from his cock. Every second it remained in Pia's mouth it seeped slightly more of the invigorating liquid into her throat.

Pia your amazing. Good Girl. Seraph praised Pia verbally. He had noticed how well she responded to praise earlier, and that was something he could easily use. It wasn't like words actually required any effort on his part.

Pia felt pride at Seraphs words. Pia was, in many ways, a quite lonely creature. Her stay at Shokushu had failed to give her many friends, and she was painfully aware that she was a lonely, small girl in a very dangerous place. Sure, she had found love in Cala, but she had also found out how much bitterer love made separation and rejection taste. The teachers seemed to like her, but the more she found out about the school, the less she trusted those who worked for it.

So, in his own way, Seraph classified as one of the few beings on this island who had actually shown her kindness and praise, and that made it important for her to pay him back, and this was the only way she knew how.
Pia would doubtlessly realized that she had been skillfully manipulated, had she paused to think, but with her brain drunk on lust and her body flooded with mana? Little chance.

She did feel a bit of shame and embarassment that this was necesarry, that she had been so weak that inreupting the training had been necessary. She also felt like she owed her lover to be better, somehow.. But all such thoughs were soon banished as the extra tendrils tickled her engorged clit. Now she only cared that she would come, soon, very soon. And more importantly, that more of the precious magic precum was seeping into her mouth.

She let her lips rest on the cock, the head about 3/4ths into her mouth, and circled the member with her tounge between the cock and her lips, before once again returning to her old rythm.

Seraph saw the pride that flared in Pia's soul at his praise, saw the bitter loneliness that fuelled her new eagerness to please him. He saw the bitterness that had been building in her soul, her inability to be with her love fuelling it. But that was not the only source it stemmed from, her lack of friends, her growing distrust of the teachers, and her desperate attempts to escape shokushu and the rapes she had suffered there. All of that bitterness left her alone, and her soul wasn't the type that enjoyed that feeling. A self destroying cycle, and one that left her quite vulnerable to exploitation by anyone smart enough to see it who was prepared to praise her and at least pretend to be friendly. Her arousal and mana addiction only made it all the easier to manipulate and guide her into behaving how Seraph wanted her to behave.

mmm ... that's wonderful. Seraph continued to praise Pia as she paused her movements to circle his shaft with her tongue. Her movements resumed the moment her tongue completed it's own movement, and one of Seraph's hands reached out and patted Pia's head, another sign that she was doing well. Just in case that wasn't enough praise Seraph directed two more feathers to Pia's kneeling body, and each of these latched on to a nipple and replicated exactly what the one on her clit was doing.

Seraph's understanding of Pia was uncannily accurate. In many ways, Pia posessed her own stenght, in the form of a certain stubborn optimism. But that strength could not live without nourishment. It was not much that she needed. Some small recognition, a kind word and some moral support, perhaps? Someone who knew this could make an eternal friend in Pia. But as irony willed it, it was Seraph who figured it out.

Another two.. limbs.. feathers.. whatever they were grew out of Seraph's wings and touched Pia, waisting no way in getting inside her open shirt and pushing aside her bra. They attached themselves to Pia's nipples, just like the one on her clit, sucking with the bells, teasing with tendrils. It was a novel experience to Pia, something between being sucked with soft lips and playing with a vibrator. That it worked was self evident, from the way her cheeks reddened with the rush of blood to the strangled little half-moans her throat made.

Okay, this.. this is it! If I am not gonna come soon, I'll die!

Pia found herself at the excact edge of the climax. She was so wet, so ready, she could swear her inner thights must be glistening. Maybe she could hold back for a second or two, but soon, very soon she would come. Just about anything would push her over the brink now.

Seraph could see Pia's arousal spike when his feather's latched on over her nipples. He could see it in her cheeks, in the strangled little half-moans emitting from her throat. But most of all he could see it in her soul. He could see just how close the cute innocent and, surprisingly considering what she had been through, naive student was to orgasm. She was so close to the edge literally anything could tip her over.

Now that created a question Seraph had literally a moment to answer. Did he let her cum on her own, or did he add something to tip her over the edge? If he added something ... what? Seraph considered the questions for the moment he had available before finally settling on a test. He knew that when he had fucked Kanoe she had cum from his cum entering her mouth, and he wanted to see just what effect it had on Pia.

His cock throbbed for a moment before Seraph let himself cum, his mana-rich cum pulsing into Pia's welcoming mouth. As it did so she would realise that it tasted far sweeter, and her body would realise that the mana inside it was several magnitudes more potent than the pre-cum she had tasted earlier. If that would be enough to tip her over ... Seraph didn't know.

Either way he continued to pat her head as he cooed Good girl.

Oh my! He is coming.. he really is!

And he was. The throbbing of his penis, how his pre-cum flowed more freely, it all told her he was about to spill. Yet she was not quite prepared for the marvelous, sparkling explosion in her mouth. Semen gushed forth, splashing against the back of her mouth. She swallowed, barely keeping up with the great gushes. And as it started flowing down her, she realized just how mana rich the pearly liquid was.
It felt like she was glowing, like a candle was shining onside her, a great ball of light and warmth moving down her throat, down towards her belly. She sucked, swallowed, sucked and swallowed again. A mad rush of emotions filled her, pride in making him cum, arousal and above all, the insane feeling of pure mana.

Now it was like her whole body was throbbing, almost like the cock had before the orgasm. And then Pia came herself, the extra mana making every erogenous zone in her body light up. It was like every single part of her had become a clit, like she was coming with her whole body. She threw back her head, even before Seraph had ceased his orgasm, releasing a moan. His cum, shining before her mana sight, hit her in the face, landed on the top of her breasts. She placed one hand on the floor to avoid falling over, the other still stroking the cock.
