Kaito said "Ok, I will tell you one of the most important things about being an adult. Your sex and everything about it."
Tami said "Please explain"
Kaito said "Well you are a girl and I will show you the special things you have that makes you a girl." He made Tami's puberty more pronounced. Her breasts grew to more than just small A-cups and hit B-cups, her pussy developed and grew some hair, and her hips grew out a little more.
Kaito said "Ok let's start with a bigger part. Your pussy." he poked her pussy and she covered after and he said "It's used for more than just going to the bathroom. It's where you can get a child. If you put a special thing inside there is a chance you will get pregnant when you can ovulate... here is how you know if you can have children."
Tami felt weird again and blood came spraying out of her pussy and he said "That is the human version of laying an egg. I'll get into more details about what you put in there to get pregnant now. However you should understand what a boy is like."
Tami again felt weird and asked "What are you doing no---" her pussy started growing into a large pole with some balls and said "What are those?"
Kaito said "That is a penis, or the male version of a pussy. Let me show you what it does exactly." he then started poking at her dick and she tried to shield it but found that it started hardening.
Tami asked "What's happening to me?"
Kaito said "you are getting a boner. soon you will see what it can do." Kaito then poked Tami's hands away and then rubbed the dick. Tami felt so aroused and cummed, spraying sperm around.
Tami asked "What was that? is there something wrong with my pee?"
Kaito said "That would be sperm. If a sperm gets into you can potentially get pregnant."
Tami said "But I can't ovulate... I've got a penis not a pussy."
Kaito said "Kind of... The lesson needs to go on."
Tami started to hold her dick as she felt something weird happening to it. The dick yanked itself from Tami leaving her with a pussy. The thing pointed towards her pussy and hardened. Tami pleaded "Please don't, it'll hurt wont it?"
Kaito said "Maybe a little but you probably would find it pleasurable."
The dick then slammed right into Tami's pussy and started moving around stimulating her and making her moan a bit. The dick then cummed in her and vanished, fertilizing her egg and making her pregnant.
Tami said "Can you do that again?"
Kaito said "maybe latter but now you are pregnant."
Tami said "But my stomach isn't-" Tami's stomach started to bloat a bit and she said "It's that easy?"
Kaito said "not always, but then again there is magic. Realistically it takes about 9 months to give birth but i'm speeding things up. Now time to show you some of the effects of pregnancy along with parts of your body that will help with the baby.
Tami's hips widened a bit and he poked them saying "These are your hips. They generally make birthing a child easier." Tami's breasts started growing a bit and then filled with milk and started leaking.
Tami said "I thought you said only guys spewed sperm?"
Kaito said "That is true, but your breasts are lactating. or producing milk. Babies generally drink the milk their mothers make from their breasts."
Tami asked "Do guys have anything other than impregnation to help the kids?"
Kaito said "We are strong so we are able to protect our wives and kids. Besides that we don't have anything that is really needed for child development besides fertilization. Now prepare for childbirth."
Tami's kid started growing faster and faster until it started to crown. Tami screamed at the pain and Kaito not wanting Tami to be too uncomfortable wished she felt sexual pleasure instead of pain. This caused Tami to start moaning and said "What is going on? uh..." The child was then born a girl with the same DNA as Tami. What happened next?
