Wet Dream

You are walking along the beach, you feel the warm soft sand spread between your toes with each step. As you walk further you come to a dune and pause as you feel a wind blow onto your body. Looking down you realize you are nude but something else seems off. Before this fully sinks in you feel a slap on your ass and turn around. Behind you is Sam your girlfriend, she seems different somehow. Broader, taller maybe, again she seems fuzzy but two things are clear. The clear look of lust on her face and a strap-on that is at least 8 inches long and 3 inches wide.

She pushes you down onto the sand dune face first, you catch your self landing chest down. Before you can react further though you feel strong hands grip you and you feel your butt being penetrated. You relax almost out of a strange reflex and moan out in pleasure as you feel her begin piston it in and out you.
