As the angel suddenly began to thrust in and out of her she was glad he took care of the movements at first. Due he voluntarily began his work it was appropriate to thank him for doing so. Thank you master. It would be enough so he won't be annoyed about it or punish her for something like that even though Ryu doubted he would punish her for something she couldn't know at all. Being a slave is a thing you need to learn, so she guessed there was nothing he would do against it, yet.

Ryu moaned gently while he kept thrusting into her wet passage as one of his hands began to move up her back. She started wondering what he wanted to do by the time, but the touch of him on her was a pleasant and a small kind of praise towards her. Suddenly something wrapped around her breasts, kneading them as the redhead moaned harder by the sensations which spread through her. It must've been two of his feathers due she still felt one of his hands caressing her rear cheek and with the other one on her back, it seemed pretty logical. M-master, it feels amazing.

She tried to be a good slave and thanked him for his proper movement even though he didn't order it, but after all it was just a nice gesture of her to express she enjoyed what he did. It didn't matter if he liked it or not, she was confident he wouldn't complain about some additional praise from her side.

As Ryu thanked him for moving inside her Seraph felt a pleasure spread through his soul that had nothing to do with the way his cock was thrusting through her tight walls. Ryu not only learnt quickly she also made guesses and assumptions about her duties as a slave and what a master would expect from her. To show his appreciation for her statement a third feather was used to caress the side of her face for a moment before it withdrew back towards the wings behind Seraph. Another thing he would have to teach her, just what his caress meant based on where he touched.

At her statement that it felt amazing Seraph saw an opportunity to further strengthen his control over her. I want to go harder, is that ok with you? By again veiling a command as a question Seraph would further embed the idea that Ryu wanted to be his slave, wanted to do anything he wished, deeper into her mind and make it that much harder for her to resist following that train of thought later.

As Seraph asked Ryu if she wanted him to fuck her harder the feathers kneading her breasts shifted, and soon each breast was looped three times by its respective feather and the tip reshaped into the familiar bell. While the feather's tightened in their coil around each breast and forced them into greater prominence the bells latched on to each nipple and began to suck the sensitive buds of nerves.

The feather which caressed the side of her face only forced her eyes to turn to look what it was. The significant praise felt good, balm for her obeying mind and soul. To interpret it though was harder for the girl than she actually was used to, maybe he would come up with something later to teach her correctly. She wanted to learn, she wanted to obey better than before.

Incredible pleasure took place in her body and as he asked her if he would have some kind of permission she quickly responded and answered. Yes master, it is ok. Ryu wanted to be his slave, there was nothing which could convince her from something else at the moment, she wanted to learn how to improve her skills to please him and to gain more of his recognition over time. His commands were like directives and she had to obey them. She wanted to find out more about his preferences, trying to get into a better stance ifhe wanted her to as well. There were so many things she could learn and would willingly accept training.

A deep moan escaped the redhead as soon as the feathers wrapped around her breasts several times to get a better hold on them, Ryu's head turned a little to see what he had in mind and saw how the tips reshaped into the bells he had used before. Quickly returning into her earlier position, she couldn't stop to moan softly as the grip tightened around her breasts, squeezing the flesh apart as the bells attached to her nipples and began to suck them. It... it feels too good, master! T-thank you for your approval... The pleasure was incredible, she just hoped he would be satisfied with her subjection before he would have to punish her again.

When Ryu answered his 'question' with the answer he had expected Seraph started to thrust even harder into her tight slick pussy, his cock sliding past gripping walls of muscle until he was as deep inside her as he could go before he would pull out in preparation for the next thrust. His new pace, combined with his feathers efforts on her breasts, quickly drove Ryu towards her next orgasm.

Seraph watched Ryu's soul carefully, he would have to time this precisely as a single fault now would undo the small link he had created between his order and her orgasm. He watched as his thrusts and the suction on her nipple brought her closer and closer to orgasm. As she reached the point where her body would have normally reached orgasm he remained silent for four seconds before finally speaking the words You may cum. As he did so he thrusted deep into her welcoming hole and held his cock motionless inside her.

The time passed again as his thrusts and the bells spread more and more pleasure through her body, even as she she reached her peak they continued with their tasks and she had to keep her orgasm back, no matter what kind and amount of efforts she would have to cast up, she would obey his command even if it would cost her anything she got. As his cock rested motionless deep in her passage and he spoke his order she released herself again, bursting her mind into a wave of satisfaction as she did.

At the point her body tightened around his member she realized that she'd been able to follow his command. It was hard in a way to resist the satisfaction she would receive if she would cum at this point, but on the other hand the longer she kept it back the better it felt and her master would be pleased if she obeyed him. T-thank you again Master, it was really enjoyable...

When Ryu managed to follow his command and delay her orgasm until Seraph's command he praised her for her obedience. Your a very good girl Ryu. Seraph's voice was one of someone praising a pet, kind and encouraging. The voice that said what you had just done was very good, even before the words that were spoken registered in a mind the tone was subconsciously understood. She had done good, therefore she would be praised. It was just the beginning, so his praise would be easily given. As his training of her continued it would become rarer and rarer, only being delivered when she exceeded what he expected her to do or accomplish.

As her walls clenched and tightened around him Seraph held his member completely motionless inside her. He waited patiently for her to recover from her orgasm before he gave his next order. As I withdraw you pull yourself off me, when I push in you push yourself on me. With that he started moving, setting up a slow rhythm of movement for her to get used to having to react to his movements to determine how he wanted her to move.

Ryu managed to stop panting pretty early, it didn't take long for her body to recover the energy she would need to follow his next order and it'd be enough to get through another one if she wanted to. It was a kind gesture of him to wait, but finally the angel gave her the next order she would have to obey if the redhead wanted to receive further praise. Yes Master. To follow his command seemed pretty easy at first, but the movement which gave her additional pleasure made it harder for Ryu. In the end, the first thrusts of him turned out to be successfully mastered while soft moans began to fill the room again.

His praise was enough for her to follow his commands blindly, it was like someone would command a puppet which had been created to fullfil its master's needs as a slave. Even though she still thought of other things and got a partly functional free mind her main task was to satisfy her master with everything she could do, something kept her from resisting but she didn't plan to struggle against him anyway.

Whereas for Ryu his order would only get harder to follow the longer Seraph dragged this on he would have no difficulty at all. After all, Seraph controlled the tempo of their movements. When he wanted to speed up they sped up, when he wanted to slow down they slowed down. Even if he had as little control as a human he would be free to act as he wanted, while Ryu was forced to respond to how he acted.

But the point of this entire lesson was to teach Ryu the basics, to lay the framework he could later build on. It wasn't meant to be that difficult for her to obey his orders. The difficult orders would come later. For now Seraph slowly increased the speed at which he moved. Never making any sharp jumps in speed he maintained a predictable increase in speed every thrust. Giving Ryu as much of a chance as he could to adapt and learn the technique.

To make it even easier, if less pleasurable, for Ryu the feathers on her breasts unlatched themselves from her nipples and uncoiled themselves before flowing back behind Seraph to join his wings. His hands continued to stroke her rear cheek and lower back, which for the moment remained his only sign of approval for her actions. As the pace increased he would add extra signs if she managed to continue following his orders.

He changed his movements slowly, either faster or slower and not making any large jumps in speed to give her a chance to get used to it, obviously he would teach her more serious techniques later or if he is satisfied by her learning progress. The basics settled down in her mind quickly, the movements appeared to be smoother than before in a short amount of time, she was glad it seemed to work so easy but of course it was just the beginning.

The angel removed the feathers from her breasts and the attached bells as well, even though it was less pleasant it made everything slightly easier than before, her mind could focus on her movements if not everything on her body got stimulated. Still, he stroke her rear cheek and lower back as a sign of approval which affected the student, she was glad he welcomed her actions that well. As he increased the pace, Ryu followed his order he made before, due her acclimatization to her task it seemed to be easier and worked quite well, she didn't make any mistake so far.

Seraph was quite pleased by Ryu's progress, as he had noted earlier she learnt quickly. So much so that this exercise was already becoming habit, an ingrained ability that she would not need to think about. While the end goal of his training would be for everything he taught her to become that it wouldn't be training if he let her continue doing such things as anything but a warm up.

In an attempt to throw her off he settled down into a rhythm, a single speed which he held for a dozen movements. Once he had reached that dozen he waited for four more movements, and on the fourth he suddenly moved very slowly without any warning or build up. The next movement was at the speed set by the rhythm, and two more followed at that speed before he suddenly pushed inside her much faster and harder. Either she would adapt to the sudden changes and be praised, or fail and be scolded. Seraph actually didn't really care which, but he would never let her see that indifference. While he knew she was progressing far faster than he expected she did not, and if she did find out she might think she could slack off in training. And that would be an unacceptable step backwards.

The angel kept a steady rhythm, it was easy to follow her ordered movements until he suddenly decided to change it, abruptly the student analyzed the tempo he was moving and changed her own movements to the same pace. Ryu moaned as he suddenly sped up, penetrating her hole without mercy. She wouldn't fail, it felt too good to get praised and his task as a master was far more enjoyable if she decided to keep the rhythm. The girl wanted to improve her skills and the only way to achieve that goal would be to please and satisfy her master if she obeyed his orders.

Still, Ryu was pleased that he didn't say anything bad about her, on the other hand he didn't praise her, but it didn't matter. A neutral status was better than a negative one, so she let that thought pass as she was able to keep the rhythm of his movements, getting pleased as before it would be hard to resist another orgasm over time.

When Ryu managed to match his sudden changes in speed Seraph's eyes flashed with pleasure. Your a very good girl Ryu. Seraph continued to structure his praise's wording, and his tone, as if he was talking to a pet. Sometimes the most subtle of techniques was the most effective. Whether she recognised it or not there was a reason people treated pets that way, it made them loyal, it made them value your praise and it encouraged them to focus on whatever they had just done to receive that praise.

Seraph decided to add to Ryu's 'reward'. The rate at which he thrusted his hips into her increased, so what was originally just an attempt to throw her off and make her disobey his orders now was the standard pace. Of course every now and again Seraph would do a single movement that was at a different speed to the standard pace. Sometimes faster, sometimes slower, sometimes very different and sometimes very similar. He expected her to match every thrust, and was quite happy with her when she did.

I do love the sound of your moans. A simple statement of fact, not an order, or a question. Just Seraph informing Ryu of something he liked. Considering her current state he was certain she would relish such information. After all, it would make her a better slave and allow her to serve her master better.

That's very kind, master. Ryu liked being called what he just stated, his praise was something she couldn't resist. She just wanted to get more of it, following his orders and to change her behaviour if an amendment to the motion sequence occured. the girl, rather called a slave by now, didn't notice any sign that he treated her like a pet, it seemed to be a rather common behaviour for a master in front of a slave he or she owned. It wouldn't disturb her anyway, the way he treated her changed nothing in the amount of pleasure she received.

The pace kept a quick and steady for a while, just to check if his slave would obey him correctly he changed his movement every now and then to see if she reacted properly. Everything matched, it was like she just noticed the change of him thrusting inside her not even a second after he did, so she was quite capable to change her own motion as well.

Every thrust he made forced the girl to moan, his length and girth were incredible pleasant as it spread pleasure through her as inner walls felt how his member withdrew and slammed inside her again. T-thank you, master. The proposition he made pleased the girl's mind, giving her an imagination of what he liked right now and she was glad something in her task seemed enjoyable to him.

As Seraph continued to thrust into Ryu's welcoming, yet still tight, pussy her moans filled the room. He let that continue as he brought Ryu closer and closer to orgasm. This time he had to try and teach her what he considered the hardest lesson yet. She had proven she could hold back her orgasm, for a short time at least, until he said she could cum. But now he wanted to see if she could release early. Eventually he aimed to have complete control over her orgasm, for his word to instantly spark it, no matter how aroused she was.

That was the long term goal, for now he just had to build the steps that would bring him closer to it. Seraph increased the speed of his thrusts, and that increase in speed was mirrored by her hips. Soon Ryu was approaching yet another orgasm, and this time a second before it would normally be released Seraph buries his cock as deep inside Ryu's cunt as it could go and releases his own seed. Earlier he had told Ryu he wanted her to cum if she felt his seed inside her, but just in case she has forgotten this he speaks the words Cum for me slave. Hopefully Ryu's conditioning will force her to cum before she would naturally do so, however reaching orgasm quicker is harder than holding one back.

Ryu's rising arousal and the pleasure provided by the angel filled the student's body, he suddenly began to increase the pace of his thrusts and her movement matched his perfectly. His seed entered her finally, the size of him forced the girl to moan heavily as its warmth caressed her inner walls and spread through her, she remembered quite well what he told her but now he gave her the order to release, maybe he thought she forgot about it. The student was about to contradict, but her task as a slave seemed more serious to the redhead.

She was close to release, but it was hard, even for her mind, to release herself even if it wasn't the time to do so. Still, there was almost no difference in time he ordered her to cum and she finally released herself with another long scream of delight which echoed through the room, inner walls contracting as they tightened around his member and seed. T-there you go, m-master. It was a strange feeling for her to force her body to do something like that, but due he was the one who ordered it she had no other choice to cum abruptly. Her body resting in her position, lightly shivering like every time she came, the girl began to pant again due the sensations and the aftermaths of her orgasm feasted on the force her body had to offer.
