A Common Tale:When Saying No Changes Nothing

He told me it would be fun
He said it was a game
I wasn't sure,
but he took me anyway.

We went into the bathroom
when noone was looking
he locked the door behind me

Suddenly, I felt nervous and scared
My heart beat faster
I told him
"I changed my mind"
but he said it was too late and laughed

He unzipped himself
And did the same for me

He was my best friend
Now he's just another enemy

(This is a common enough story, though the details may differ. They All Said No. They Were All Ignored)
