The Ole Grandfather Cock

sex move used by a male to pleasure two females at the same time. have the two females face away from you, one in the front and one in the back. place a strap on dildo backwards so that it is facing the girl behind you and also erect the penis towards the front girl. then rock from back to forward once every second.

when one finds themselves in the middle of a threesome and out of ideas, it would be wise to wip out The Ole Grandfather Cock.

teach your grandfather to fuck

to try to teach somebody something that he knows far better than you.
