When a chick is on the rag, on her heaviest day, you begin by sodomizing her. At first very slowly, while giving her a reach-around and flicking her clit until she is almost ready to cum. You then pull out and drive home in her kooter, which should by all means ignite an orgasm on her part, thus tightening her kooter around your shaft and sending the back pressure of her juices, and I do mean all of them at this point back upon your shaft, thighs and balls. This is known as the classic Crimson Gusher.
"So Dude ... I was banging your mom last night when she gave me a crimson gusher."
