We've rented a Beach House. It overlooks the sea with a large bedroom facing the waves and a floor to ceiling glass facade. We've been together a few months and your quiet demeanor hides a risque and erotic streak that I am slowly uncovering,
I imagine us at the house, returning after an evening out. You're wearing a dress and I'm in my dinner suit. We enter the bedroom and put on a bedside lamp. I take off my jacket and move to you. I take your hand and we walk over to the window where we look out. It's a full moon so we watch the sea and the waves crashing to the shore. It's a clear, warm but windy night and the beach is almost lit up by the moon's radiance. You're stood in front of me with you back to me, my arms around you.
I start to kiss the back and side of your neck. My hands caress your body through your dress. I see your nipple harden through the flimsy material. You respond to my attention with little moans and you push your bottom back and feel my hardness against your perfect cheeks.
I slowly undo the zip on your dress and push it gently off your shoulders until it drops to the floor. You're bra-less and you're now naked except for your tiny lace thong. My hands caress your small pert breasts, squeezing them as I pull gently at your very erect nipples. Your breathing becomes more noticeable as your excitement at your exposure and potential discovery, mounts.
Your hands reach back and you undo my trousers to release my fully erect member. I push against you again, sliding between your cheeks and pushing against your bottom.
There is just a thin piece of material between me and the puckered opening of your anus. You gasp. I know you love to feel me pushing against you there. You place your hands on the window as I thrust gently against you, to steady yourself and take my weight against you. I take off my tie and shirt.
It doesn't take long before you cum. Your body shudders and your legs almost collapse as the excitement of discovery and what I am doing to your bottom gets too much for you.
