a sexual fingering techneque. the index and middle fingers are out, and curved. so is the thumb. they are curved to make a "C shape." the thumb is placed in the vagina, the index and middle fingers are placed in the anus. after insertion, much pressure is applied.
I C-Clamped my bitch so hard that she waddled the next day.
