Mandy saw you getting hard again at her slightly larger size. She watched in awe as your relatively small, skinny, 2 inch flaccid penis slowly swelled to it's full size of almost a foot long.
"It's not gonna eat you..." You said.
"Look, I don't wanna grow anymore..." Mandy said. "Don't get me wrong, I'd be all over you right now if it wasn't for this whole thing."
This discouraged you. "Oh..."
"I know this is an odd thing to ask. But I have a couple of friends who are...petite. They would love to grow." Mandy said.
"You want me to make them grow?" You asked.
"If you don't mind, and they don't mind, then everything would work out." Mandy said. You agreed, and Mandy called her friends. After some arguing and talking, Mandy finally convinced them to come over. About 15 minutes later, in walked Shauna and Caroline.
Shauna was something like, 4'11", but extremely fit. She was a professional dancer. Not stipper-dancer, but more like, fitness/pop dancer. Her breasts were maybe just filling an A cup, and her brown hair matched her brown skin. Her gypsy background brought an exotic look to her.
Caroline was a little taller, and larger chested, but not as fit, Although still attractive, and still petite. Her b-cup bra sat up her 5'1" frame, and her dark black eyes and dark black hair went very well with her pale skin.
"So...this is the guy?" Caroline asked.
"Hi." You say.
Shauna giggled a bit. "Hi? That's it? You supposedly have a magical penis, and we are here to test that, you don't seemed phased."
"So, what is the normal reaction to this? I just found out my penis is magical, too." You responded.
"Ok shut up." Mandy said. "How is it supposedly when, look at me."
"You don't look that much bigger..." Caroline said.
"Look." Mandy said, and took off her shirt.
"Still doesn't look like enough to convince me. How much did this guy pay you to gang bang us?" Shauna said, and all three girls laughed.
The girls began to weigh Mandy's breasts, and examine her body, with their eyes and hands. They didn't intend to be sexual about it, but you saw it as only that, and began to get erect.
By the time the girls finished groping Mandy (and making out with her in your mind), they looked back at you, and the two new girls gasped at your huge penis.
