Your bodies wake up simultaneously, and you feel each getting aroused at the sensations coming from the other. Idly, you wonder what it would feel like to have intercourse with yourself, and in response, your cock twitches and your pussy gets moister.
Both your bodies get dressed, and you still can't help but revel in the sensations coming from your mom's body. If you were in the same room, you know you'd be fucking yourself wantonly.
Your mom regularly checked on Alice and Julie shortly after she awoke, and you do so, finding them still peacefully asleep. You can't help but admire their nubile forms, and while being a mature woman feels great, you wonder what it would be like to control some younger bodies.
You also realize that even though you can mimic your mother perfectly, there's still the chance of slipping into your own habits. Alice and Julie would certainly notice, as might some of her co-workers. Then it hits you: you can kill these two birds with one stone.
Holding the stone, you say, "I want to be able to control any number of bodies as my own, have simultaneous awareness, and be able to work all of them at the same time. I want to be able to take control of any body I can see."
You feel no different, but you want to test this sooner rather than later. The stone isn't glowing--so you guess something happened--and while you were making your latest wishes, you had your mom's body preparing breakfast.
You hear Alice and Julie up and about, getting dressed. At the usual time, you call, from your mom's body, "Kids! Breakfast!"
The three of you shamble into the kitchen, and unable to contain your anticipation any longer, you take over your sisters' bodies.
Through three pairs of eyes you see a bulge growing rapidly in your pants, and in response, your mom's and Alice's pussies grow damp and their nipples harden, Julie not yet having started puberty. But again, you think, that can be fixed easily enough.
