Ninja Cock 

A cock so powerful and overwhelming that you have no idea what to do with it. An elite warrior. It is very speedy and unable to be tamed, specialising in a vast array of martial arts. The ninja cock has multiple times the power of a normal cock, and those who possess a ninja cock have a high ranking within their society. Only the very worthy come into contact with the ninja cock as it is very special.

Renee's ninja cock was so powerful and strong that Jess became un-conscious when she witnessed it.

The ninja cock knocked me out cold.

NINJA Gaiden

The disrespectful act of sneaking up naked, on an unsuspecting woman during sex, bending over and farting in her face while she has her eyes closed, disappearing before shes opens them leaving her no choice but to ask "what was that?'' this will only count if someone is fucking her and she is face up, also for best results her head should be slightly hanging off the bed.

last night davenport and I ran a train on this army chick and while he was fucking her I pulled a ninja gaiden.

this chick was so stupid I had my boy pull a ninja gaiden on her.

while pence was having sex with his girl I ran in there real quick and pulled a ninja gaiden
