The class laughed at Jason as he stood completely naked at the front of the room. Mr. Bretman looked around as Ty tried to find his next target. There she is.
To no one in particular, Mr. Bretman wished that the guys in class would stop growing when he said 'puberty'. And then he turned to Jason. "Jason why don't you stand to the side for a moment? I'm going to show the class something new." More than willing to be out of the spotlight, Jason waddled his hulking body to the side of Mr. Bretman's desk.
"Now," said Bretman as he walked down the aisles. "We all know what happens when a male goes through puberty. What about a female?" I look around at the female classmates. Most of them have started developing already and are beaming at their blossoming figures. But then I get to the end of the row. "Marny Robbins. How are you?"
Marny squeaks "I'm fine sir" while trying to cover her body with a big hoodie. But I know what she looks like, plain. Plain and flat. But let's change that. "Come with me to the front of the class Marny." She hesitantly gets up and follows me, while I say "I wish for every time I say 'puberty', Marny will grow more feminine. And I wish for her to do whatever I tell her her even if she doesn't want to." No one hears me but the fun is about to begin.
I have Marny stand up where Jason was in front of my desk. "Alright Marny before we begin, take off your jacket."
"Um no I'm fine," she stutters out but the wish makes her do it anyway leaving her in a plain gray t shirt and baggy blue jeans. "Thank you Miss Marny. Now..."
Jason interrupts me from his corner "What are you going to do to her, you..." But I still have control over him.
"Jason be quiet!" His mouth slams closed. "Keep quiet and keep yourself busy. Why don't you work out? A growing boy like you needs excersize." If he needs excersize, giraffes need to wear high heels. Nevertheless, Jason starts doing naked push ups on the floor.
I turn my attention back to Marny and the rest of the class. "Okay. Now where we're we? Oh that's right: puberty, puberty, puberty. We were learning about puberty." Marny leans back onto Mr. Bretman's desk as the changes start to hit her. Her completely flat chest starts to perk up as small breasts begin to grow. She stretches two or three inches taller as her legs lengthen and get more shapely. Her hips also start to widen as she gains a pretty cute figure.
But I said puberty four times so the changes don't stop there. Her breasts keep growing bigger and heavier and her nipples almost pierce thru the cheap fabric of her shirt. Her bigger bust also lifts up her shirt so we can see her thinning waist and her tight jeans pinching her as her haunches grow. Her mousy brown hair grows longer and longer as it curls and thickens down her back. Light dusting of brown hairs appear on her arms as body hair sets in. Her uncovered stomach reveals that arm hair isn't the only place hair is growing in.
Marny squirms while she stands, certainly feeling strange with all the growth. "So class as you can see, females obviously experience growth too. Let's first look at her breasts. Marny, take off your shirt so we can see what puberty changes."
Marny tries to fight it but she doesn't get a chance to argue as her body grows again forcing her mammaries to break through her shirt, leaving her topless. She tries to cover herself with her arms. "Arms down Marny. Now class her breasts are around a 34D. But throughout puberty and the rest of her life they can keep growing." Marny grunts as her body grows again, her breasts the most obvious change. "See? Now she's a 34DDD. She's got some nice genetics working for her." I squeeze one in my hand. "So nice and meaty. Perfect for feeding a baby one day. Notice how when they get bigger, the areolas also get bigger." I'm getting a kick out of fondling her chest like this. But I move on, leaving my actual body sitting down with a good sized erection.
"When females go through puberty, their bodies change in other ways too." Marny gasps as she swells even more. Her butt and thighs push out of her jeans and her long luscious legs are revealed to the class. The only thing left in her body is her underwear, which have been turned into a thong by her wide hips. "The purpose of female maturity is to be ready to have a baby." I slap her 36F breasts together, making them slosh around. "To feed the baby."
I pat her new wide hips "...and these are to hold the baby. Pregnant bellies can get pretty big so women's hips need to be able to hold the belly up."
Someone from the crowd shouts "Why is she so hairy?"
"Good question. Marny has grown a good bit of hair all over her legs, arms, ... "I move her hands away from her lap and above her head "underarms, and pubic areas. Humans are mammals so we grow hair. Though girls normally grow less than males. Any other questions?"
"Why is Marny squeezing her thighs together like that? Is she okay?" I turn to my assistant, who is struggling to hold herself together. Looks like she caught a glimpse of Hercules working out in the corner of her eye. I shake my head and laugh. "Oh yes she's fine. As we go through puberty," I pause to watch her fill out some more as she squeezes her thighs harder and starts rocking her hips" our bodies get overrun with signals called hormones that tell our body to grow and to mate. It's the instinct to have sex and procreate, to keep the species alive. And she's feeling the urge pretty badly." Man, with all of the hormones I threw at her, she must be seriously horny right now. And since I told Jason to shut up and work out, he hasn't even noticed her strong scent of arousal.
"Alright class, I have shown you what physical changes both guys and girls go through during puberty." Marny cries out as she grows again her breasts around a 36J, booty around a size 20 with the same small toned waist from before, and standing at 6'. Damn lets keep this party going.
"Now I'll show you how babies are made."
