When Several of your bros are on the beach and doin" it with they ladies. All at once, they take out they man meat and dip it in the sand. They then re-insert it into the vagina. All the ladies will scream!!!! A Flock OF Seagulls.
Mike and the boys were in the sand dunes doin' it with their girls. They took out their man meat and dipped them into the sand and then re-inserted.......The girls screamed and it sounded like a flock of Seagulls.
