The class was stunned. For a long moment they looked at their former peer sweating and panting in the afterglow of the woman on woman sex. They all looked interested though.
"Wow she's got bigger boobs than my mom," One girl said.
"Brenda how was it?" Asked another.
Brenda responded by getting up. She seemed in awe of the changes. Her breast were incredible, at least as big as her older sister. Brenda was well informed as to what getting older meant, having walked in on her sister 'entertaining' boys. That had led to a talk with her mom. Still she hadn't really understood. Now new thoughts and sensations were flooding into her mind. She ran her hands over her transformed body, stopping at her breasts to massage them lightly. It was a wonderful feeling, so sensual, such pleasure.
"You guys gotta try this," Brenda said to her classmates, looking down with an almost predatory look.
One by one the class said yes, eagerly. Jeannie smiled. This was going great. She was free now, and finally able to do what she wanted. She'd made Brenda older, but that wasn't all of it. The ex-little girl was much more than an 18 year old. Not that Jeannie was going to tell Brenda that, or tell whatever she might do to the rest of the class. They didn't know it but they were hers.
"Alrighty then one room of grown ups coming up..." Jeannie said clapping her hands.
"Wait," Brenda said touching Jeannie on the arm. Leaning close to the genie Brenda whisphered something into her ear. The class looked puzzled but said nothing. Jeannie smiled, whatever Brenda had whisphered was something the genie liked.
"Here we go," she said then granted Brenda's wish.
