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."
