Growing up nudist you get to learn about sex

I grew up with a sister mom and dad.
everyone was always nude, me and my sister were
tought at a very young age to be comfortable
with out bodys and clothing was optional,
me and my sister would swim at a lake we had
on our 160 acre property so we could be nude
all the time, our parents thought it would work
out better if we lived in the country where
no one would judge us and no one would judge
our patents for having nude children around,
our friends would come over a lot they would
be nude to everyone was comfortable with it,
i would see a nude girl other than my sister
and get a raging little boner but no one made
fun of me for it, as we got older our bodys
started to change, every other week my balls would

hang lower and lower, my sister started to grow
little boobies, it was hard to see that, she was
getting older and growing more and more hotter
every day i would get a very hard boner when i seen
her, we would still go swimming in the lake
nude and play together touching our bodys together
it didnt bother us, my little boner would brush
against her body she wouldnt really say anything
but it felt good when it touched her smooth body,
we would get out and dry off she would be staring
at it for a long time asking why it was that way,
i dont know sis it does that when i look at you,
really? why? she would ask. i really didnt know why
but it felt good, she got closer to me to get a better
look at it then before i new it she was right down
there by it i could feel her hot warm breath on
it it made it even harder. does it hurt she asked,
no it feels really good i tell her, can i touch it
