Now there is 3 genders (unaware like in the reality he had just come from)

Jack felt a bit strange like the world blanked for a second and maybe it shook or something he felt weird but then he felt normal again.

"Ok class lets turn our text books to chapter 3 page 27 were first going to look at humans and the external characteristics of our body's" the boys and girls go out their textbooks and there was rustling of flipping pages, jack didn't really notice much but the girls books were a bit bigger than the boys but he didn't really think about it to much .

Jack turned the book to its pages and on the page was a picture of a naked boy and girl. The teacher continued " as you can see the diffences between boys and girls is a bit different boys are marginally smaller and have a nice set of holes we call a vaginal complex with a hole called a vaginal opening or pussy or frontal pussy and Behind it another hole which called the bussy, or behind pussy. Within the Bois vaginal complex or rather infront of it there is a urethral like tiny hole as well as a little bump called a clitoris. where as girls have a penile structure which includes a long, thick, hard penis with a urethral hole at the front , then under a large set of testicles housed in ball sacks and at the back the anus" Jack hadn't given it much though before noticing the diffences, he had seen his sister whilst peeing this morning, he thought back to try and remember it , he remembered Kelly peeing into a urinal on the wall where as he had to stand squat over a Bois toilet which was essentially the same thing like a urinal but on the floor of course spreading his sissy legs over it and peeing spraying his boi pee all over before Kelly helped him clean himself up. but thinking of her penis he didn't look in to much detail, He was curious now and wished he had.

whist he knew about his urethra or something existing he hadnt ever payed much attention to behind them, he now sort of realised there was another set of holes there, he wondered what they were for and why they were there. whilst he was thinking and becoming aware of it something must have happened in his body and mind as he started to feel it, it's like the holes in his crotch and on his backside decided to wake up for the first time as his mind learned how to clench there muscles and he felt them wink and pucker and squeeze and it almost felt like maybe it was almost moist inside them . He felt them go deep inside him and they felt kinda empty.

Looking around the classroom it looked like the other boys might be thinking the same thing. The girls looked differnt some looked like they were holding back something some with hands on chests or on crotches, maybe they needed to pee or something he thought. Some were deeply engrossed in their textbooks, wide eyed and almost drooling over images and text in them. He was going to try and peep over at his sisters desk when the teacher spoke again.

"This is what you all look like at the moment however class today is a special day as you will be changing into adults which means your body's will go through some changes some of you might even have started to experience them " the teacher continued "Now class if you turn the page you will see the changes to the adult body's"

Jack turned the page to see another set of naked body's of a man and a woman. Looking at the diffences he could see between the previous to the adult form it was clear that they both grew a bit taller although now the female was significantly taller and the body looked a bit more firmer and slightly more muscular than the male.

He also noticed that the image of the man labeled sissy male Wombboi had a bright pussy looking slick and wet the folds pink and leaking with fluids. he could see that maybe a little button at the front he didn't know what it was (clitoris head) but now looked a bit larger peaking out of its little hood of skin looking super sensitive. He also noticed that the chest had expanded a bit looking kind of puffy like a small breast, the small breasts with longer nipples and the darker part (areole) looked bigger he thought it wa nice how it looked wide and circular. The male had shorter hair tied up on thier head like little pigtails but the book also mentioned they could have a bun or other hair types if they wished.

For the womans page he noticed that infact there was not one but two female forms labelled Futa and Fem. first he noticed both were taller and looked beautiful than the male Wombboi, thier chests had expanded into larger breasts with small nipples and smaller (areole). As he looked downwards he could see that above the penis area the females now had a lot of hair like a jungle and whilst he had seen the males had hair there it was only a little amount in a small triangle shape . Thier large errect penises and balls? significantly larger than the image of the girls. The images of the larger more beautiful women made Jack feel all tingly inside focused mainly on his bussy and pussy. One image of the women labeled Futa showed a woman with long waist length flowing hair tied up behind her the book referencing other longer hears styles, she was happy looking with a joyous smile she looked energetic and lively. Her large penis with a purple mushroom like tip standing to attention and her large balls in thier sacks below. the penis labeled as something called errect . Somehow this penis image stuck in jacks mind and the image in the book of the Futa looking all happy and smiling gave him friendly vibes like he'd want to meet her.This contrasted to the image of the Fem who had a shorter shoulder length hair but the book said it could also be a bob cut, she looked stern and empowered with a more serious looking facial expression she gave of professional business woman vibes but also it was clear she was the one who was in charge. Her penis a bit larger nd thicker than the Futa womans as well as her balls, this time her penis looked like it had a flat head and this Fem penis head was flared and looked like there was spikes and bumps all down the length before getting to a larger bulged section before the base. When looking back at the Futa he noticed she to seemed to have one of these bulged parts near the base but her penis didn't look as intimidating.

Jack had so many questions why where they differnt looking and why did women split into two and males only into one option? Why did he now have these holes? A pussy and a bussy was it? And his pee hole tho that was always there he just didn't think or look at it till now. This vaginal complexity thingy he'd looked st it either or even looked at the bussy hole.

Aside the males image was also a back image showing the butt checks had also become more plump the hips had widened very slightly and the bussy hole now looked like it had some slight external rippling folds like the pussys and was looking moist and shiny. Seeing this made him feel more moist in that area but also seeing the naked woman made his body tingle all over, it was so beautiful, he was very intrigued and it was like he was only just realising this now.

Meanwhile the teacher had been talking and explaining this whole time whilst Jack had his inner thoughts, he looked at the board and around the room the girls looked like they were more excited where as the boys looked like him kind of interested but were confused, and overwhelmed buy this amount of information they wouldn't be able to retain in thier small brains.

On the board the teacher had images of something called sperm and ovums , from what he could gather from the images sperm was inside the Futas sacks inside the balls called testicles and the Fem made the ovums inside there own larger balls? or rather something balls called ovaries, inside thier sacks and when they meet they have a chance to make a baby. Thinking about baby's made his body feel overpoweringly tingly again next multiple places from his bussy to his pussy to the clitoris to the nipples even deep in the pit of his belly area. Tho he didn't know how the were made because either he hadn't been paying attention or it wasn't mentioned yet.

He focused back to reality as the teacher started talking "ok class in a Minuite we are going to split up so as to do the medical checks and school injections as well as to cover a couple of topics with boys and girls speratly." "First the girls will go to there medical exams and have a break before coming back for a girls only class. Boys will stay here for the time being for a short class before they have there more extensive checks and there break and then after there final class boys only before the girls rejoin and we have a final class of the day." "Ok so girls you may leave, boys stay."

The girls all got up and started walking out of the classroom giggling , Kelly quickly said good by to jack and said everything would be ok if he just payed attention to the teacher and the screen and said that he would see her and his mother later on and not to worry. She then left with her phone in hand and the teacher closed the door and dimmed the light again before pulling up a second presentation.
