"What the hell is going on in here!" Shouted Rachel after the initial shock wore off. "Who the fuck are you two? And how in the hell did you get in my house?"
Maya and Rina quickly seperated to opposite sides of the bed. "Uh, Ray, I uh, well..." stumbled Rina as she was so flustered that she couldn't formulate a proper sentence. Maya was much more relaxed though and so she took over for her sister. "Sup Sis? When did you get home?"
"Don't Sup Sis me. Who the hell are you?" Snapped Rachel. She was now more annoyed than enraged since seeing the two girls completely naked had completely changed the atmosphere in the room.
Maya, still feeling like being rather playful, answered in a way that she knew still wouldn't satisfy Rachel. "Well, the simple answer is that we are your younger sisters." This bought her a kicked from Rina. "Stop being an asshole."
"Ah! Ok, ok." Said Maya, rubbing her hip. "Well, I am not lying. We are your younger sisters, but I guess I should mention that we were your younger twin brothers."
Rachel relaxed a bit more, but still didn't believe them. "Oh yeah, you two are my 14 year old twin brothers? Sorry, not buying it. Even if I ignore the part about you being two girls, you both clearly are not twins and you are also much older than 14."
"Rachel, it is the truth though. I am Ricky, and she is Max" said Rina, trying her hardest to convince her sister. But Maya spoke right after her. "No, my name was Max, not is Max. And now my name is Maya. And also, she is now named Rina, not Ricky."
"Maya. Rina. Well, now at least I know your names. But that doesn't make me believe you are my brothers. If you have any proof, then I won't call the cops. But if not..."
Maya then got a mischievous glint in her eyes as she leaped off of her sister's bed and over to the Chronivac. "I can prove it!" She said with excitement. Maya brought up her sisters information and then added her own special touch to it as fast as she could. Just when Rachel was out of patience, Maya finished and pressed confirm. She then got back onto the bed to excitedly watch the excitement she just unleashed on her older Sister.
Rachel quickly began to feel that something about her was very wrong. For one, she felt very uncomfortable in her clothing. However she didn't feel heavier, and if anything, actually felt lighter. Her outfit suddenly began to pull apart and white feathers began poking through. Her pants fell down, revealing her now yellow legs thinning slightly and inverting at her knees. Now panicking, Rachel stripped off the rest of her clothing to reveal that a good portion of her body now was covered in white feathers. Everything below her neck save for her front and legs were feathered. Her feet had turned into talons and her arms were now contorting into a large pair of wings. At the base of her spine, a feathered tail grew and finally her pussy and asshole merged together into one. Rachel had become a harpy.
The bird girl frantically looked herself over before wobbly taking a few steps forwards with her new feet. Her talons leaving a trail of small indents in the floor due to her unfamiliarity with them. "Wha- what did you do to me? Turn me back!"
"See, this is my proof. I did the same thing to us, well, almost the same. I did make us not twins, 2 completely different species, and 18 years old. But that's all" explained Maya.
"Max!"
"Maya! My name is Maya now" corrected Maya.
"Fine, Maya. Fix this. Now! Turn me back to normal or so help me I-" angrily shouted Rachel before she suddenly went very quiet and her face paled. Her body squatted down and she looked as if she was about to break down completely. She then let out a very erotic sounding moan as something white crowned out of her new cloaca. The object kept inching out of her slowly until it fell safely onto the floor. Rachel had just laid an egg, and there were still a few more left inside.
Each egg was roughly the size of a softball and weighed just about as much too. It took her a full 20 minutes to lay all 7 of her eggs. Durring that time, the most she ever said were just a few pleasure filled moans and gasps. Rina collected her eggs for her and Maya was busy quickly constructing a bed sheet nest for them. The eggs were unfertilized, but Rachel still felt relieved by having them in a nest for some reason. She actually felt a need to sit on them too.
After her last egg, Rachel collapsed onto the floor panting and covered in sweat. "It's finally over." She looked over at the pile of eggs and her catgirl sister who was asleep in the nest with the eggs wrapped up with her tail. Rina didn't have much to do anymore, so she just moved to sitting on her bed while patiently waiting for Rachel to recover herself.
"Fuck! Fuck! Maya, I am so going to end you if you do not turn me back to normal this instant!" Shouted Rachel after resting for a few minutes.
However, she didn't realize that Maya actually had fallen asleep though. So when Maya woke up completely startled and jumped up onto the top bunk, which surprised Rachel. "Wait what? How did you just...?"
"Jeez don't scare me like that" complained Maya. She hopped back down onto the ground and went back to the nest and laid back down. She didn't fall asleep though. "What's the issue now?"
"Turn. Me. Back. To. Normal." Demanded Rachel. She somehow managed to get to her feet and carefully walked over to Maya with her wings folded to her sides. She then grabbed Maya's head with her foot and pulled her out of the nest. She made sure not to poke her with her talons though.
"Oww! Hey stop it! Ok I will turn you back." Said Maya who couldn't free her head from her sister's grip. Rachel let go of Maya and watched as she sat down and started changing her profile again. It was a quick fix and in less than half the time it took the first time, Maya finished and confirmed the new settings.
Rachel sighed in relief as her human body returned in full, with everything normal looking and facing the correct way again. She checked her crotch and confirmed her pussy and asshole were once again seperate orifices.
What she didn't know yet though, was that Maya didn't just undo her harpy transformation. Maya had snuck in a few subtle changes, such as huge cravings for seed and cornmeal meals only with a desire to up her calcium intake,sher resting arm posture would be folded back against her body like wings, and of course, the ability to lay eggs. Albeit her eggs would not be nearly as large though, but she would on average lay 12 eggs every day.
Rachel didn't notice how she kept her arms tight to her body with her palms facing outwards as she left the room in a hurry. She did stop and walk back in when she remembered her eggs, a d what she found her sisters doing initially with eachother. "Are those going to hatch?"
"Did you get fucked in the last hour?" Replied Maya.
"No, and it's not your business if I did or not either."
"Well, if you didn't, then I doubt they will ever hatch" added Rina.
Rachel felt relieved after hearing Rina say that. If Maya said it, she still would believe it, but part of her would not trust it either. "Hey, what were, well, I know what, but why were you two doing that when I came in here? Is there something I should know about going on between you girls?"
Of course, Maya made sure she answered first. "Well, I was horny and milking Rina makes her horny too, so we were helping eachother out, by eating eachother out." Rina blushed hard hearing this. But she couldn't argue against it either because it was, while poorly worded, the truth. She was so horny from being milked that she just ended up going along with Maya's flow without thinking.
"Right... well, just don't go too crazy. You teo are still related after all. And will you both be... staying as you are?"
"Yep, I am happy with my new self" said Maya to no one's surprise. Rina on the other hand looked torn. She wasn't sure yet. She had initially hated it, but after being milked, a significant part of her seemed to have accepted this new body. So she just shrugged for her reply.
Rachel didn't really care either way, because she was just curious. And now having gotten all her answers, left the room again. She went back to her room and went to her computer right away to buy a couple of cat toys and a laser pointer so that she can mess with Maya and get some payback for today's events. She also bought some canned cat food and some cat treats too, just in case she could find a use for them.
