Man, on the drive home from Disneyland, I had to take a serious shit; I was totally turtling.
Cock Turtling is the term of which is used for when a male slowly inserts his penis into a woman's vagina, mouth or any other orifice. When the cock has become rock hard, like a turtle's shell, the man will proceed to "beat the rabbit" and fuck the orifice as hard as he can until he splurges, therefore beating the rabbit, the rabbit being the girl's interest in the action.
"Hey man, I was walking in your kitchen and I caught you Jenna fucking on the table. What the fuck man?"
"Aww dude, I was fuckin' her at that moment, I was cock turtling' her. Going in slow and then BAM right in the kisser."
