20 year old woman, medium breast size, medium length blonde hair, wearing torn bikini, embarrassed, trying not to cum. Sitting on beach, legs spread, knees bent, close to water, facing water, side view. Pink tentacles originating from the sand between legs are fucking her. Beach is extremely crowded by adults, many people who have few to no detailed features are relaxing normally on the beach behind and to the side.
