Yes. As Paige uttered that one word Phoebe's unborn child knew what it must do. It must destroy the bond between the Charmed Ones. That bond had kept them safe from evil. It allowed them to rely on each other even in the most dire situations. After that trust between them is broken they will turn on each other and It's father, the Source of all Evil, would be avenged. The child used its maturing powers to further draw Phoebe and Paige into this unholy union. Piper would have to wait, It's powers could not reach that far yet, besides she would need some human persuasion to forget Leo.
Just then Piper walked in. Phoebe quickly pulled away from Paige and moved over to Piper.
"Did you two get everything straightened out?" she asked them.
"Uh-huh," Phoebe said as she turned her gaze to Paige's breasts and licked her lips, "we sure did."
"Yeah everything's as it should be," Paige announced, as the baby's evil magic fueled her already intense desire for her sister, as she also moved over to Piper who sat down at the table.
"Well good then," Piper said as her sisters sat down next to her. Paige started running her hands through Piper's hair and Phoebe put her hand uncomfortably high on Piper's leg. "Okay guys a little too much touching right now," Piper emphasized, feeling an urge she repressed immediately, but her sisters didn't stop. "Ha ha jokes over now stop!" Piper demanded, as the baby's magic tried to dim her love for Leo, that one thing was holding her back. They still didn't stop. "Knock it off!" she got up out of the chair forcefully, almost knocking it over, and stepped back. She couldn't take anymore, she was about to burst with lust and she wouldn't let herself do that. Phoebe moved into the chair she had occupied.
Paige and Phoebe settled for caressing each other instead. Phoebe was rubbing up and down Paige's legs and stomach, while Paige stroked her sister's cheek and neck. Piper was disgusted, or at least she tried to be, but she couldn't look away as Paige and Phoebe started to kiss each other. She wanted to feel their soft full lips meeting hers, their ripe, red, tongues inside her mouth. She tried to fight these emotions but she couldn't. She wanted to be a part of what her sisters were sharing at that moment.
"What are you doing?" she forced herself to say. What she wanted to say was 'Hey what about me,' but she knew she couldn't. She was the oldest sister and she had to do what was right and set an example for the others, it's what Prue would have done. "Stop it!" she said in a tone that showed her true feelings, but her sisters simply ignored her and kept kissing. Piper couldn't take it anymore. "Listen if your gonna do that don't leave me out!" she finally admitted, the magic mixed with her innermost yearnings breaking her resolve, "but don't tell Leo." That made the girls stop.
"That's all we wanted to hear," said Phoebe.
