"My First Time Ever!" joke

The sky was dark
the moon was high
all alone
just her and I
Her hair was so soft
Her eyes so blue
I knew just what
she wanted to do
her skin so soft
her legs so fine
I ran my fingers
down her spine
I didn't know how
But I tried my best
I started by placing
my hand on her breast
I remember my fear
My fast beating heart
but slowly she spread
her legs apart,
and when I did it
I felt no shame
and all at once
the white stuff came
At last it's finished
it's all over now
my first time ever
at milking a cow
