As the guy limped off, three girls watched the scene and were slack jawed at what they saw (and horny).
Pat, Suzy, and Trish left their boyfriends (staring at all the other women there) and ran to Jenny
"Miss! Miss! How did that happen?"
"What, the guy with the 10ft shlong limping away?", Jenny didn't even sound surprised, she knew the girls wanted something.
"YES! But how?"
"Easy, I'm a genie, sort-of...", Pat then cut her off with "Genie, with wishes and all that? How many do we get for catching you?"
Jenny thought this would get old fast, so she just reciprocated "You can't catch me, but I can give you a wish. Hold still for a second.."
Jenny read the girls minds, they wanted their boyfriends to pay attention to them alone, and since two of them were heavy set, they wanted to be slim and sexy. Jenny decided to fix them up in a way she thought would be clever.
"Ok, I know what you all want so I propose this: I'll make is so any excess eating you divulge in causes your asses to enlarge, in a firm and sexy way, and your breasts grow voluptuous and round but firm. I'll make it so your breasts enlarge faster than your ass. And to make sure you don't over do it, milking your new tits will let you regulate the size of your new assets. How does that grab you?"
The girls were taken aback, they thought they get to wish, but that wish would cover it. Suzy spoke up first, "How do we know your a genie? What do you get in return?"
Jenny was getting pissed now, "One, I only want to be left alone, and two how do explain your two foot cock?"
Suzy was puzzled until she felt a tingle in her crotch as her bikini bottom stretched to contain the first foot of cock growing. The second foot left her standing with a large erect cock in the beach air. Her friend begin to fondle it but she shouted back "What the hell, stop that or I'll come".
Jenny smiled, "After your friends jerk you off, they can begin eating at the buffet to grow the DD tits they'll need to get their boyfriends to pay attention."
The friends attacked her cock and she screamed with delight after a few seconds. The girls felt normal, but they looked more trim and athletic. The heavier girls already felt their asses expand and their tops grow tight, but only a B or C cup. Pat thanked Jenny as they ran to the desert cart.
They each grabbed a cake, the whole cake, and consumed them in marathon time. As they watched their belly's distend, their bulges shrank as their tops grew tight as perk breasts grew two more cup sizes. After a few seconds, each girl suddenly jerked upward as their rears bulked up.
The three guys each did a double take as they stared at the breasts, waiting for a top to snap off.
