He tells her, then demonstrates some more

“Okay,” said Dave, “you got me. See this bone? It gives me powers.”

Becky stared at the bone in Dave's outstretched hand, mesmerized by it. She slowly a finger out, as if to poke it.

Dave pulled his hand back. “I think I'll keep it to myself. But would you like another demonstration?”

Becky seemed to wake up from dizzy spell. “Oh... yeah! Do something big!”

Dave scratched his head in thought, then decided what to do. “I wish all the girls here would come to this room.”

Girls streamed in. Some from the lawn in their bikinis, some from upstairs only half dressed, even the triplets came in naked from the Jacuzzi, dragging Tilly along on her leash.

Dave moved next to the triplets and gave the closest one a sloppy kiss as he fondled her large breasts. She responded with wild intensity, rubbing her curvy body all over him. Dave momentarily forgot himself and concentrated on her wild tongue and her sensitive nipple.

Dave pulled back and saw that the twenty other girls in the room hadn't noticed him. Some were pointing at Becky's new body and they were all confused about everyone deciding to stand around in the living room at the same time. Only Becky was staring at him confusedly, which reminded him that the triplets and Tilly are invisible to her, and nobody else could see his group at all.

“I wish we were visible to everyone,” said Dave.

“What the hell?”

“Where'd they come from?”

“Look at those naked skanks!”

Becky's jaw dropped, which pleased Dave. He loved how impressed she was at his power. However, the snotty comments from the other girls pissed him off.
