"He entered me again and again, and every time, his cock grew longer. After the twentieth thrust, an unusual but extremely pleasurable thing happened. I felt his colossal cock wander throughout my body, finally going up my esophagus and emerging out of my mouth.
I looked down, my eyes straining to focus. The crown of his mouth was now dangling out of my mouth, as though to say hi. It looked like a tiny snake, but I knew it was no snake."
