Ass job is a term for a sexual technique in which an individual masturbates their partner by placing their penis between their intergluteal cleft, known colloquially as the butt crack or ass crack.
The term takes its name from the colloquial term "hand job" which refers to a similar masturbation technique using the hand instead of the intergluteal cleft.
Ass job is sometimes written as one word, assjob. An ass job is also known as butt cheek sex, a butt job, and a hot dog.
An ass job may occur when a person grinds their buttocks against a partner’s penis to bring them to orgasm, or when the penis-owner lays their penis between their partner’s buttocks and strokes themself to completion. The person performing the ass job might sit on top of their partner and rub their butt cheeks against their partner’s penis. Alternatively, the person receiving the ass job could straddle their partner, who lies on their stomach.
While an ass job is performed near the anus, anal penetration is never a part of an ass job. However, an ass job may be part of foreplay before anal or vaginal sex.
As the ass crack does not produce any natural lubrication, the use of a personal lubricant can enhance the sensations experienced during an ass job.
