Nicole ties up her victim in a position that leaves him vulnerable to head scissor holds. Now that she's tied him up the way she wants him, she can carefully wrap her strong legs around his neck and playfully control his ability to breathe. At first she uses her thighs which put him out easily. So then she challenges herself by using only her calves...but his neck is no match for the size and strength of her calves. So he's out several times in this clip.
