Wacking one out quick
Quick one out of the shower
Cumtributer knocks one out over me!
Knocking one out while watching porn!
Rubbing a quick one out
Knocking the bottom out
Knocking a nutt out of my booy
Rubbing one out real quick
Knock out!!!
Tuggin' out a quick one
Rubbing out a quick one
Running out a quick one
