Where two people consentually have sex on a beach. Usually favouring the missionary position (however using one's imagination, many more are feasible), the man pulls out, dips his erect penis into the sand, and re-inserts his now 'crumbed sausage' into the vagina of his partner, or casual fuck buddy. Beware of chafing.
