Nikki did as Jessica asked and was going to keep her friend as her dick for a little while longer. Then she started to think of a change she could make in herself, but her bedroom door was opened by her sister Emily.
"Nikki, Mom sent word that you should come downstairs because dinner is ready." Emily said, but noticing the cum marks on her sister's shirt and that she was naked from the waist down "I'm going to tell Mom you're getting changed and it's going to take a while to come downstairs." and left closing the door.
"I'm really hungry. So shall we get dressed and go downstairs?" Nikki said
"Okay, but first, check it out." Jessica said poiting to the computer screen. There was a new profile there, as Chronivac had scanned Emily the brief moment she was in the room.
"I see that now sister's profile is there. Don't tell me you intend to make any changes to her like you say you did to me?" Nikki said
"Maybe, but this time the two of us are going to prepare her move together." Jessica said
"I do not know. What if she doesn't like it?" Nikki asked
"We just put it in for reality to be changed just like I put it for you, this time so that only the two of us are aware of the changes." Jessica said
"Okay, but we don't have much time." Nikki said
"So let's do it like this, a simple change but impossible to hide." Jessica said
Having come to an agreement Nikki changes her sister's profile and stood to allow Jessica reach and put the finishing touches before finishing, with them setting the transformation to take two minutes to start and occur slowly.
So Nikki dressed up in a simple t-shirt and jeans, without putting on her boxer shorts after being convinced by Jessica, who also preferred to stay out through the open zipper of her jeans.
"Finally. Why take so long just to change clothes if you're not going out? Sit down and eat before the food gets cold." Nikki's mother said
Nikki sat at the table next to Emily, while her mom and dad were sitting side by side across the table. There was also a much smaller arm into which food was placed for Jessica.
The meal was great and nothing got in the way as Nikki and Jessica glanced at Emily occasionally to see the signs of her transformation showing up.
Emily felt that there was something wrong with her panties, as she had to adjust her panties all the time. It was complicated for her to have a big clit, as it was hard to find comfortable underwear like that. She looked sideways at her sister, for she envied her. She was torn about wanting to be a girl with a normal clit, but she was also jealous of Nikki and wondered what it would be like if Jessica was between her legs and not between her sister's.
Having arrived late, Nikki and Jessica watched as Emily and their parents finished their meal and left the table one after the other, but it was still not possible to notice any change in the older sister. They finished eating last and got up, Nikki washed the dishes and silverware that she and her dick had used before heading upstairs to their room.
"I think we put the changes in your sister to take place too slowly, I didn't see anything different about her." Jessica said as they started up the stairs
"Or the program didn't work at all." Nikki said as they reached the second floor.
"Psst...Nikki, come here." they listened. It was Emily who called them through the half-open door to her room.
"What you want?" Nikki asked
"I just want to spend time with you." Emily said opening the door to her room for her sister to enter.
"So what would you like to do to pass the time?" Nikki asked
"I'm sorry about that Nikki, but it's not you I want the most, it's Jessica. I know my pussy is too shallow but I want her cock to play with it and my big clit." Emily said blushing, lowering her underwear and exposing her throbbing 2-inch-long clit.
"What do you think of this Nikki?" Jessica asked
"I don't think so, she could end up pregnant." Nikki said
"I think it won't be a problem." Jessica said giving her friend a wink.
Nikki then gave in and took off her clothes, her sister doing the same with the rest she still wore. The sisters sat facing each other on the bed, very close to each other, and Jessica bent down and entered Emily's pussy.
Jessica looked curious as it was the first time she had seen a pussy from the inside, but she didn't get much inside. Only the humanoid part of her, which was just the tip of her cock body, could enter and she couldn't go any deeper. As it was the first time she'd been in a pussy, especially one that shallow, she didn't know exactly what to do, so she just moved her arms and her head so that she rubbed as much of the surface as possible. The plan worked and she could hear Emily moan at the stimulation, so she continued, stopping when she felt the girl approaching orgasm. Jessica then pulled herself out, let a minute go by and hugged Emily's three inch clit, rubbing her hands and sucking on the tip only to stop again as she approaches another orgasm.
"You're too good, Jessica, but you're also cruel, pushing me on the edge like this." Emily said
"I also want to come." Nikki said
"I'm going to make you come like never before." Jessica said. She then lowered herself between Emily's legs, coming face to face with the smooth skin there, which was slightly sunken where a normal girl would have a pussy. She ran her hands over the sunken area, which was sensitive, and once again stimulated the girl and stopped once more with her on the verge of an orgasm. She left it for another minute and went back higher, hugging her friend's sister's 4 inch cock, which she hugged and sucked on the tip, slowly descending the shaft until she reached her embrace the girl's balls.
"Emily, are you there? Your friends are there inviting you to a party with them. Are you going or not?" Nikki and Emily's mom said from the other side of the bedroom door, interrupting them.
"Tell them I'm going, yes, but they need to wait a while for me to choose what clothes I'm going with." Emily said
"Okay, but don't take too long." her mother said and went downstairs.
"Now we have to go soon, but we have to sort this out first." Emily said pointing to her 6 inch hard cock
"I can't wait to finish it either, I'm at my limit." Nikki said and she and her sister hugged each other, starting to rub their dicks against each other.
Jessica put her arms around, hugging Emily's manhood once more. Both sisters were on edge and neither of them took long, they both turned from side to side and came almost at the same time, not caring about both of them fucking staining the floor.
At the end of their orgasms, the sisters took a tissue each and Emily cleaned the rest of the cum that was on the tip of her 7 inch cock and Nikki cleaned Jessica's mouth.
Emily got up and opened her wardrobe to get an outfit to go to the party and, finishing putting on her boxers, she turned to Nikki and asked if she wanted to go with her to the party.
