I don't really want to!

There was a girl and her mother. They went to the park one day.
The mother had to go get something from the store so she told
the little girl to stay at the park and be careful. There
happened to be a little boy across the street and he wanted to
play with the little girl. So he came over and asked the girl
if she wanted to play in his front yard. The girl said "I don't
really want to, mama told me not to." The boy said, "I'll give
you a quarter," the girl said," ok." So they went and played
in the front yard. Then the boy said, "Want to go inside?" The
girl said, "I don't really want to, mama told me not to." He
said, "I'll give you $.50." She said "ok." So they were
playing in the the toy room and the boy said, "Do you want to go
to my room?" The girl said, "I don't really want to, mama told
me not to." He said, "I'll give you a dollar." She said, "ok."
She they were playing in the boy's room, and he asked her, "Do
you want to have sex?" The girl said, "I don't really want to,
mama told me not to." He said, "I'll give you two dollars."
The girl said "ok." So they were having sex and then the boys
mother comes home. She goes upstairs to the boys room, and
finds them having sex. She yells, "Get off my son!" The girl
says, "I don't really want to, mama told me not to!"
