You liked the amount of power being your mother granted you, so you decided to use even more. While yes you could force your sisters to do chores and annoy them getting them to do things for you, You had a better idea...
Calling up one of your friend's parents Ian you began your plan, once you heard the line pick up you said: "Hiya this is Mark's Mom Jane; Mark wanted to know if Ian wanted to come over today if that's OK with you could you ask him?" You said in a sweet motherly tone, you knew Ian was doing nothing today and he would love the chance to be over even if it was because he liked looking at your Mom and Sisters. After a while of silence on the line a voice woman's spoke up "Ian isn't doing anything today so he should be able to and if he wants to he'll be right over!" the woman said happily, giving a brief thanks over the line you hung up and began to wait for Ian; he only lived a few blocks away and would be here anytime. In the meantime you turn your attention to your 'new' body again groping the giant mounds on your chest.
As time passed you soon heard the ring of your doorbell, quickly walking over to the door to greet Ian in your new body, opening the door you see two of your friends now Frank and Ian were stood clearly oogling your body as you welcome them in. "Mark is downstairs in the basement let me show you." as you beckon the two slack-jawed and silent teens into the basement; as you headed down into the empty basement both Frank and Ian realized that Mark wasn't there "Where's Mark?" Frank said confused, You turn to him "I'm Mark, I found a device that let me swap with my Mom!" You say excitedly, both Ian and Frank didn't look too amused by the look on their faces thinking this to be some prank; You come up with the best way to prove it "Well then if I'm not Mark would my Mom let you do this!" As you lunge forward grabbing one hand of both of the pair and placing it on your breasts making sure to squeeze down on them, which admittedly made you moan directly in front of them. Both of the boys entranced by the situation suddenly come to their senses and pull away, being freaked out and then suddenly stop and look at you "So, you really are Mark?" Ian said, "Yeah, and I had a plan I wanted to share with you Ian but you brought Frank and it might of messed it up..." You state bluntly,
"How do I mess up your plan?" Frank spoke up.
"Well you see I wanted to get control over the rest of the family, I already sent Mom in my body to my room and now I wanted to get Nikki's body under my control, so I was gonna switch you with Nikki." You confess
"What if I didn't want to be in Nikki's body?" Ian questions
"Dude I know you would love to be in that body but as for Frank I don't know; you can stay out of this man if you want or join in" You point out, for a moment Frank looks off into space as Ian who clearly was shut up by what you said sulks knowing your right when Frank looks to you and speaks up again "Well... Your younger sister I wouldn't mind swapping with, she's not far off the shape of Nikki if not a little chubby but... being honest I like that.", You are a bit shocked at what he had said but it works out perfectly, with a devilish grin coming across your face you decide to enact your plan.
Bring out the tablet and look the swap options when you realize you could of swapped two other people with this mode; making this even easier you lead both the boy's upstairs where you come to find Nikki sleeping with her door open; You whisper to Ian to go lay down on the floor in her room while you set up the swap for both Nikki and Ian and once Ian was on the ground and ready you intitated the swap a beam of light between the two shoots out and Ian's eyes flutter shut while Nikki's body stirs and gets up, suddenly looking down a herself she grabs her chest and begins to feel herself and move her hands down her body and then she looks up at you smiling "Wow, it's... real!" Ian squeaks, you quickly shush him and point to his old body now sleeping on the floor.
Moving onto their next target Abby who was currently on her phone and playing a mobile game most likely; thinking about how this could go wrong if both your friends bodies started to rebel against you, you decide to try out the brainwashing (individual) setting and use it between Frank and Abby, though you thought it may not work in your favor if Frank isn't the one who uses the tablet you give him the tablet and tell him what to do with it and after a extensive explanation Frank walks in receiving a complain from Abby and suddenly silence as a confused Frank walks out the door and looks to you "Oh, uh Mark's Mom? why am I here and what is this?" he says offering up the tablet to you, "It's nothing, You came over to see Mark; his room is right there." You gesture to your room's door, as the brainwashed Abby in Frank's body awkwardly shuffles off and into your old room, Abby steps out into view grinning from ear to ear with both hands firmly planted onto her chest "She's big for someone younger than me." Frank in Abby's body says slyly.
Now with both Nikki and Abby's body in control of your best friends you decide to:
