Gaping

Gaping in pornography refers to scenes of either anal or vaginal sex with a focus on the recipient's orifice remaining open for a period of time after the erect penis, dildo, or object is removed. A sub-set of gaping is the tunnel cumshot, wherein the male ejaculates directly into the gaping anus.

Gaping is a natural occurrence and typically does not result in damage to the performer, though as always there are health risks with anal sex. Any activity within a performers anus should involve large amounts of lube.
