Directly. He can do whatever he wants.

“Okay girls, from now on you all happily do whatever I say.” The wishbone throbs in Dave's hand as the girl's turn into his willing slaves. “Go ahead and move this table away from the couch. I want plenty of room for you girls to sit on the floor in front of me.”

The triplets slide the coffee table into a corner of the room. They sit down on the carpet in front of the couch and look up at Dave, making him feel like a king on his throne.

Dave's cock pushes painfully against his pants. He pulls it out to relieve the pressure. The girls gasp and start to object to him whipping out his cock in their house. Dave realizes he'd only wished for them to do as he says, not accept whatever he does. “I wish you girls all loved me and wanted me to always do what makes me happy.” Their shocked expressions turn to adoring gazes. Dave smiles down at them as he slowly strokes his rigid cock.

“Okay girls, time to make some changes. You're all really hot. Yesterday I'd have been thrilled to fuck any of you without the slightest complaint. But now I can have perfection, so why bother with anything else?”

The girls giggle. Melissa says, “If you want to fuck us now, we don't mind. Go ahead!”

“Soon,” says Dave. “First, your sisters should have long hair like yours, Melissa.”

Rachel and Danielle's wavy red hair grows down to their waists. The girls gasp at the magic transformation.

“Nice!” says Dave. “Now it's time for the good part.” Dave concentrates and the bone pulses in his hand again. He watches the girls' t-shirts shift as the breasts within them grow. Dave jerks himself faster as the girls gasp at their transformations. Their breasts grow and grow, until they're almost as big as the girls' heads.

“Oh my god!” says Rachel. “How did that happen?!”

“With this little bone!” Dave holds up the wishbone with one hand while jacking off with the other. “It can do anything to anyone. And you love that!”

The girls suddenly love the idea of someone having the power to change people. One of them looks at Dave hungrily and says, “That's so hot, Dave. Use it on us some more!”

“No problem!” Dave makes their huge breasts super sensitive.

“Ooooh!” One of the redheads rolls her hands over her chest. “That feels soooo good. When we got big I thought I'd start wearing a bra, but now I think I'm too sensitive. I can't even stand to wear this t-shirt.” She pulls her shirt over her head, revealing her soft, bouncy breasts to the room.

“Nice!” yells Dave. “I want all of you up here to give me a feel of those tits!”

The triplets crawl onto the couch eagerly. The first one straddles his lap, leaving the others to kneel on either side of him. Dave reaches forward and grabs the breasts in front of him. He watches himself grope them with a huge grin, but soon his vision is cut off. The triplets on either side of him are pressing their breasts into his head, burying him in titty flesh. Dave moans as the three girls shift their bodies around, rolling their big breasts all over his face and hands.
