Hypothetically, what if you are drunk and you are with this girl. The two of you are making out and you want to have sex. Unfortunately, you pass out. When you wake up, you find out that she had put on a strap-on penis and fucked you in the ass. She took a big shit on your forehead, too. She video taped the whole thing.
She tells you, "That's what I intended to do the entire time! I didn't think you'd mind. I only finished what WE started. You didn't approve of this? Oh well. Sorry. I guess I misread you."
You wouldn't feel a little violated? You wouldn't punch her in the nose and demand three-fiddy?
