The Back Half

When a man with a huge penis is fucking a girl with a small vagina, the girl says to only put half in. The man then slams the whole lot in real hard.

She - "Only put half in"
He slams the lot in and she cries out in pain.
She - "You said only half, you said only half"
He - "Yeah - the back half Bitch".
