You find her stranded on a lonely beach and she pleads for your help. Of course being the gentleman you are you oblige. You roll her around in the sand and make sure that one by one your cock is satisfied by her mouth, her pussy and that lovely tight ass hole of hers.

Once you have finished she is covered in sand even between the cracks of her pussy lips. As she gets into the sea to wash it off you walk away leaving her abandoned on the beach where you found her.
She shouts at you asking why you didn't help her and you reply that you did. She must have gone a long time without a Fuck on that beach and you have done your duty as a gentleman to remedy that, but as some one who respects the environment you can't take something away from the beach...
