War...War never changes, especially when it was a war between Hell and Earth.
Jun was a researcher to help Earth win this war. He wasn't much of a fighter, but he knew science well enough. One thing he did not know were magical spells. He stood in a lab room with various other researchers watching him while he held onto a burnt book. He remembered what they told him to do. He just felt afraid to do it. "Okay, here goes nothing." He mumbled to himself. He looked at the words in the book and opened his mouth. The next words that came out from his mouth were not his own, but of a womanly demonic voice. As his mouth moved on its own, his eyes worriedly turned to the other room where the researchers watched behind a glass panel. Upon seeing a purple swirl leave Jun's mouth, the researchers panicked and ran out.

The swirl from Jun's mouth slowly formed a creature right in front of Jun. The creature was clearly that of a demon, and a succubus at that. She was a purple-skinned succubus with black high heels and latex that went up to her knees. She had latex on her arms, as well as two devilish horns and exposed tits with rings on the end of them. Her cunt also exposed itself, and as she formed in front of Jun, she grinned. "Oh? He was right. Humans are so curious that they'll summon us behind the front lines!"

Jun jumped back just as the demon finished arriving. The swirl left his mouth, but his agape jaw was speechless. "I...I..." There she was. It was a real demon standing right in front of him. The scientists hadn't prepared for a demon to arrive. Sure, they locked the doors in case something happened, but they didn't assume Jun would be in any danger from a demon. The most they expected was a spell book and some strange magic.

"Hah, I look sexy, don't I?" The demon teased with a grin. "Well, I've always said to make love, not war. Perhaps you'd like to join me."

"Join you over there in Hell?" Jun shook his head rapidly. He heard the stories about people turning into demons. He also heard about demons torturing people before they converted them into whatever they desired, or just killed their mortal body so that they might torture their soul for all eternity.

"Now, don't be so hesitant." The succubus placed her hand on Jun's cheek and her other hand on his crotch. "I'm guessing humans tell you how bad we have it, but it's really not so bad. See, eternal damnation isn't that terrible. You get used to it after a century, and then it changes into pleasure. However, if you enter with the right mindset, it's pleasure from the start."

Jun was unaware his cheeks took on a purplish hue as the succubus stroked them, but he could very well feel his erection throbbing between his legs. He knew they were on camera as well. "N-no." He mumbled. "Go away. He put his hands on her chest in an attempt to push her away, but as he did, he felt just how soft and warm her body really was.

"Better than any human you've ever met, right?" The succubus teased. "Go on, play with them."

Jun felt as if his hands magnetized to her chest, and he could feel his own chest grow the longer he held hers. His fingers squeezed her chest gently and he shivered. He could tell she was transforming him, but he couldn't stop her. "Ahn...ern." He tried to think rationally. He was a researcher for a reason. 'They're at least getting all of this on camera.' He thought to himself. 'Good! Maybe I can get a copy to masturbate too.' He added, and then paused. "You're...you're changing the very way I think too, aren't you?"

The succubus casually shrugged her shoulders. Her hand stroked Jun's growing shifting cock. "What if I am? You're enjoying it, aren't you? Even if I didn't change your body and mind, I can tell you would have loved it."

Jun knew what a succubus did. The creatures were more powerful than imps were, but less powerful than many other demons. What they lacked for in strength, they more than made up for in cunning and manipulation. Jun was an average human, so of course he had dark desires now and then that the succubus used against him. He could tell she was making his cock much bigger than before. He looked down and saw a bestial flare at the tip of his molted horse cock. "F-fuck." He said quietly. He could feel his body shift and change with more feminine curves. He wasn't sure what he was becoming, but the pleasure built up and up in his body. "Can't...orgasm."

"Ah, so you know an orgasm will seal your fate in your new form." The succubus giggled. "You are quite an intelligent human. I look forward to making you my sister. Imagine all of the humans we can corrupt, and all of the sex we can have! If you're a 'really' good girl, I'll let you use this thing on me."

Jun imagined having his way with the succubus. He imagined them in a bedroom that he figured was Hell, as he had her thoughts and her mind the more she continued. He was still in there; he just had to maintain control of himself. He could feel his brown hair turn pink and grow long just like hers. He could feel his feet arching upward into hooves and he felt a sleek spaded tail grow out from his rear. Jun couldn't contain himself any longer, his newly enlarged cock orgasmed onto the succubus. As he came, the changes washed over his body. His chest pushed out as big as the succubus's was, and his rear grew as big as hers were too. Pump by pump, he turned more and more into her until, once his orgasm finished, he looked almost exactly like her if not for the large horse cock and balls between his legs.

Once Jun finished his orgasm, he blinked rapidly through his new pink irises. He had a different smile to his face as he turned to the succubus. "And here I don't even know our new name." She said with a chuckle.

"You'll learn it in due time." The succubus gave Jun a loving kiss. "Now, my dear sister, let us begin converting the rest of these 'scientists' to our cause."

Jun nodded eagerly. In a matter of one orgasm, his demeanor changed. He no longer cared about science or research, but sex, fun, and of course, converting others to their cause. "Gladly, my dear twin sister."
