Sandy ass
From Voyeurweb's Wiki about Sex
A sandy ass is an ass covered with sand. The sandy ass might be part of a sandkini. A sandy ass usually features a sandy anus. A sandy ass is only good for visual effects and to protect her ass cheeks from sunburn. Other than that there is no practical use for a sandy ass: A sandy ass cannot be assfucked because fucking a sandy ass will lead to serious skin irritation.
