The desired effect, of course!

Adam and Heather woke up on Adam's bed later that day, memories of what had happened flooding back.

"What...happened?" Adam asked. His question was a valid one. Looking at Heather, he could see some very nice changes had happened with her.

Heather's bubble butt had larger and rounder, straining her skirt to the max, and her tanned legs had grown longer. Her tits had received the biggest change, however, growing from an E cup to an F cup while remaining perky and stretching the skimpy blouse she'd wore to school to its limit.

Meanwhile, the busty Latina was marveling at how Adam had changed. He'd gained a fair amount of muscle, giving him the faint outline of a six pack and some definition on his arms and legs. What really took the cake, however, was his dick, which had burst through his pants. Stiff and veiny, it had grown a little over an inch, passing a foot long, and it was oozing precum. To go along with it, his balls had also expanded, each bloated sphere producing jizz at an alarming rate.

"Shit," Heather said. "It's enormous!"
