[Role Reversal, Kissing, Genderswap]

For all summoners, there is one grand law to follow. Always have a backup plan when summoning demons, especially the ones that have connections to the sin of Lust. If you don’t, you’ll be their pet instead of the other way around. But should you succeed in dominating their soul, they will bring you untold power until the day they expire.

Not many actually heeded this law because they were overconfident. Binding creatures to their will had blinded them to their weaknesses. That was how a plague of Succubi ended up filling the continent a scant few years ago. Only the efforts of the Hero, Mars, caused their dominion to die down.

And yet… Despite this, summoners still acted recklessly. Like they weren’t in danger of being charmed by their own summons. Like they were always going to dominate them. It was getting to the point where another plague could arise at any moment, should another summoner cock it up.

Which was why one of the Hero’s companions, a youth by the name of Nept, found himself drawing a circle upon the floor of his homely abode. If anybody had to breach the dam, he thought that it would be best if he was the one.

“I just hope I get one of the easy ones.” Nept muttered to himself as he carefully traced his staff across the floor, drawing pentagrams upon pentagrams. Each stored within the next, getting smaller and smaller. Every layer would expand the range of demons he could summon, but also increase the power that they had at their disposal. If he was lucky, he’d be able to summon a basic succubus. If he was well and truly unlucky, he’d summon a demon on par with the lord that once subdued the lands…

The young man took a deep breath as he inserted the staff into a slot in the very middle of the circle, as the energies stored within the pentagrams started to sink in through the wood. He could feel it pulsating, trying to smash him against the walls of his home… But he stood his ground.

One by one, the pentagrams began to spin. The connection to the demon realm opened, as the wooden staff started to thicken. To enter the human world through a summoning, a demon needed some form of medium. This was another mistake that the summoners of the age forgot. If they had nothing on hand, they would end up the hosts, and the demon would easily turn them into their pets.

Pent watched as the staff, which had formerly been spindly to account for his less-than-stellar physique, thicken as the demonic essence poured into it. Rather violently so at that, to the point where the wood was already taking on the shape of an experienced broodmother.

It seemed like he had hit the proverbial jackpot. That is, if he wanted to summon something much stronger than he was. Only the strongest succubi were this thick. Of course, he could be making the wrong guess, and he accidentally summoned a demon associated with Gluttony. But he knew he had been right. He made sure of it.

Even as the staff grew plush and the texture shifted from wood to flesh, he was sure that he had managed to snag a succubus. How could he be sure? The easy way was by observing the tip of his staff, which had been endowed with a dreamcatcher, as to allow him to process his own foreboding dreams. And in the middle of that dreamcatcher, stuck wriggling around until its body fully formed, was a horned and devilishly horny heart, the main characteristic of a succubus.

Nept reached underneath his robe as he tightly clenched an amulet, watching with baited breath as the dreamcatcher was torn apart, and the wood extended around it. Forming a womanly figure with a heavy bust, bigger than anything he had ever seen before. Even the females that his good friend Mars had as companions were nothing compared to this succubus. Just what he had he managed to summon, if they were this powerful..?

By the time the staff had been completely consumed by the demonic energies and twisted into a humanoid form, a woman now towered over the young man. Only by a few heads, mind you, but enough to cast a shadow upon him. Judging by the elegant wings wrapping around her body, and the ashen white hair… She had a lineage that was unmistakable.

According to the scholars that studied demons, the highest tier of succubi all had two defining characteristics that tied them to the succubus queen. Pale skin, and white hair. Considering the woman towering over him, it was clear that she was one such succubus. Just his luck…

“My my. And here I was, just picking out a gift for Mama.” The tall woman giggled as she slowly kneeled down, keeping her wings wrapped around her form to keep some amount of modesty while she brought a finger to the boy’s chin. “Then you just had to come around and ruin it. Because that’s what you boys do. Try to pull us from our life. You know what we do to boys like you, when we find out that you’re being awfully rude?”

Nept took a deep breath. He could feel his cheeks flushing bright red as he looked at the much taller woman. Breasts bigger than her head, hips that could crush him outright, and a mildly plump belly that showed signs of motherhood. Suffice to say, his attempt to tip the boat had completely flipped it over. And if he didn’t do anything to make up for his mistake, then he was in even bigger trouble…

“What’s the matter?” The demoness said, as she slowly let her wings pull themselves apart, revealing those fat areola hidden underneath. “You know you want to play. You shouldn’t hold back, it’s just awful. You summon us to this world, and you tease us by not having your way with us? Just, the absolute worst thing you could do…”

As the demoness got closer and closer, nearly pinning him to the ground, there didn’t seem to be a way out. He’d be drained like all the other summoners before him, and he would be turned into a succubus that would repeat the cycle. And with his conversion, the dam would break, and a gate to the demon realm would open.

Which was why he couldn’t let that happen. And why he had made all the precautions in the world. “You want me to ravage you? You should’ve said so from the start!” The young summoner said as he suddenly pressed his lips up against the taller demon, sinking his plump kissers into hers.

A spark pierced through the taller demon as she tried to back away. She was familiar with this sort of spell. It was the same sort of spell that had been used on her when she was but a tiny demon being raised by her dearest Mama.

“How?! How can a human like you wield such power?!” Her confidence shot through the floor as the panic slowly filled her expression. Not just because of the feeling burrowing through her, but because of the look on the boy’s face.

Now that her charm had been broken, it was his turn. By grabbing her wrists to prevent her from getting away, he continued kissing her. Planting kiss upon kiss on those lips, making the spark pierce through her again and again.

Moans started to slip loose from her cock-pillows as she struggled. But the more he kissed her, the harder it became for her to struggle. Not only that, but a majority of the strength in her body quickly faded away. It was like she was being dominated by her Mama, those very same kisses having served a similar purpose when she was a little tyke with power still building within her.

After a few more kisses, the tall demon was forced onto her back. And now the boy found himself on top of her, with his body pressing down her breasts. His kisses sending more and more dominating shocks through her…

“S-Stop… I-I don’t wanna…” The succubus cried out, only for another moan to reverberate through the air, and for her body to react. Little by little, she started to shrink. Just like it did back then.

The kisses were made to completely pacify demons like her. Not just by sending a strange form of pleasure through them, but by sapping their strength and turning it against them. The more pleasure filled her, the more her body changed.

Her curves stayed the same, remaining just as fertile. But her breasts, which had ensnared many a man to lie within her bosom, were shrinking. Until they were completely flat, leaving her looking more and more like an overly bottom heavy boy.

Nept pulled back, panting as he watched the demon. “Are you going to tell your kin to leave? If you do, I’ll stop.” He gave her an ultimatum. Because if he kept going, then he probably wouldn’t be able to stop himself either…

The demon looked up at him. She trembled. She squirmed. And she nodded. “I-I promise. I’ll tell them all to disappear. I’ll make them all go home to Mama! So please, stop kissing me!” She cried out, her heart trembling from all the pleasure inside her.

It seemed like her summoner understood, as he let go of her. Her expression slowly brightened, as she grinned. That fool. He would really trust the word of a demon? She would pin him below her heel, and drain him for doing this. He would understand just what he messed with..!

As soon as she lowered her guard, thinking that she could turn the situation around, Nept grabbed her by the back of her head and pushed his lips up against her one more time, properly slipping his tongue in between as well. Letting all of his magic power pour into her in the same way as the other kisses, forcing her to take it all and accept her punishment.

The succubus squirmed and whined as her eyes started spinning like slots on a slot machine. She could feel the pleasure pouring through her, and this time it was too much to stop. And since she had already lost so much of her body to those pacifying kisses, she knew what came next.

Her hips thrust forward as her pussy popped out in one swift movement. In its place, having truly inverted, was a thick looking cock. Much more appropriate for her new form, considering how much she looked like a thick-hipped femboy.

The succubus, now deprived of his feminine traits, squirmed as he began to thrust forward rapidly. There was no hole to enjoy, just a feeling of eternal pleasure. This was how his Mama pacified him, and all of his sisters.

By turning them into easily dominated femboys. They would think with the heads down below, and they’d be completely unable to do anything for themselves. They’d rely only on her. And since his summoner knew the same kind of spell that Mama used…

Nept smiled as he pulled back, the squirming femboy panting and thrusting, cum splattering forth from the hole on his cock. “That’s what you deserve. For everything that you and your sisters have done to this world.”

“M-Mmph!” The succubus couldn’t muster up a response, the mean words digging into him as he started to thrust harder and harder. With that much thrusting, even the lack of friction in the air would make it hard not to climax.

Indeed, the succubus let all of his hot seed spill out as he thrust one more time. Leaving him completely vulnerable… And dependant on his new Master, as a masculine symbol appeared where his womb would’ve been, showing his complete and utter submission.

Nept sighed, smiling a little as he pulled out the amulet inside his robe. An amulet that had the same sort of symbol. A gift from his dearest Mars. A gift imbued with the kind of affection that he held for his friends.

That was the thing that incapacitated succubi so much. Love. Love from their Mama, which the Hero’s indirect love was almost as strong as. And since it seemed to work so well against one succubus, maybe it was going to work on all the others..?

It was something that he had to experiment with… after he had fun with his new pet. And judging by the tent in the young summoner’s pants, there was a lot of fun to be had.
