“Hey Julie, are you feeling alright?” Derrick asked, looking at his red-faced sister. The two of them were in the hotel room waiting for their parents to return with the luggage.
“Yeah, I’m fine, I think it was just some bad soda.” Julie replied. That wasn’t totally a lie.. Ever since she’d drank the soda at the food court, she’d been feeling incredibly hot and ... uncomfortable, to put it lightly. She kept fighting the urge to pleasure herself, knowing that she would have little in the way of privacy while on vacation. Maybe she could quickly “relieve” herself in the bathroom and pass it off as gastrointestinal distress?
Julie got to her feet woozily, stumbling a bit, and her brother ran to her.
“Julie?” Derrick asked worriedly.
“It’s ok, I just….think I’m gonna throw up.” Julie said quickly. “Help me to the bathroom.”
Derrick quickly put her arm around his shoulder and the two slowly made their way to the bathroom. As it turned out, this ended up actually being an incredibly bad idea in hindsight, as, physical contact with another person only served to make Julie’s symptoms worse. Faltering with a loud cry, the two of them tumbled onto the hotel room floor.
“Oof! Julie, are you OK?....Julie?” Derrick said. He had gotten up into a sitting position when he noticed something about Julie that freaked him out. Namely that her face was even redder that before….and that she was staring directly at his crotch.
“Julie what the fuck are you looking at!” Derrick yelled. He attempted to push her away, but was met with a horrifying realization: he couldn’t move!
“Don’t worry bro….” Julie began, but her tone of voice just made him worry more. “I’m gonna make both of us feel real good….”
Quick as lightning, Julie was undoing the fly her mortified and parlyzed brother’s pants, neither of them noticing as Julie’s eyes turned from blue to yellow, or as her figure became ever so subtly more womanly.
Finally Julie managed to free the “toy” she had been desiring and began to “play” with it in her hands, which were quickly becoming a light shade of lavender.. Derrick grimaced as he felt Julie’s touch on his body. It was so wrong….but felt so right.
“Julie...please….” he protested weakly. He could feel himself becominng aroused between his legs as Julie toyed with him.
“Not yet, dear brother.” Julie said in a voice that was definitely not her normal one. She began to quickly discard her own clothing, leaving her completely naked below the waist. She then sat on the floor of the hotel room, and continued to tease, this time grasping her new toy between newly-clawed feet. An uncharacteristic sadistic smile crept over her as she continued. She knew her brother had foot fetish ever since the day he forgot to use incognito mode on his computer.
They continued like this for some time, with Derrick continuously edging closer to release, but the girl, or rather woman now that used to be his sister kept denying him. Indeed Julie had changed dramatically in the short time since they had began. Her pale complexion had been completely overtaken by lavender, her chest and hips had matured to almost goddess like proportions. It was hard to tell that they had started out as brother and sister.
Then suddenly the near-succubus pushed Derrick to the floor and spun around, placing her ample lavender buttocks in his face. “Ok, Bro enough fooling around. You’re going to get your release, but you better not disappoint me.” she hissed. Eagerly, the boy entered into his transformed sister, settling into a rhythm that satisfied both of them. Julie could feel the “presence” of not only Derrick, but the rest of the hotel as well as the two of them came closer to release. So many people, staff and visitors to seduce and “play with.”
Then as suddenly as it began, it stopped as with a wild cry, both of them released, too entranced by the passion to notice the wings and tail that burst forth from Julie’s body.
