The term 'Sinking-a-digit' is commonly used when referring to a technique of female masturbation.

In most cases, the finger is 'sunk' into the females vagina with the view of creating an orgasm. This technique can be used on oneself, or administered to a 'special friend'.

In some circles, 'Sinking-a-digit' can be used on or by men, however this depends on several different variables. Mostly, the male must enjoy arse-play!
Boy meets girl at the fair, boy falls for girl, they board the rollercoaster and boy begins 'sinking-a-digit' into his new special friend.
