A very rare technique used in handjobs, most women dont know. Usually handjobs arent great , but the doorknob makes it great. It's a method of using all 5 digits and twisting and screwing the head of the penis with lube of some sort. It looks like someone trying to open a doorknob with a greasy hand. Feels amazing.
I usually dont cum from a handjob but Billie used the doorknob technique and I blasted in a minute.
Tying a sock on a doorknob to signify to others that you are inside the room having sex. You do this as an international sign to say: do not enter. If you do, you will regret it and I will be embarrassed.
Sometimes called a doorsock
My roommatesaw the sock on the doorknob, so they knew I was in there having fun with my partner.
It is literally a rubber band hanging on the doorknob, used to warn a roommate(usually in college dorms) that the other is currently having sex in that room.
If your ever having sex and you dont want your roommate to come in by accedent then just put a rubberband on the doorknob.
