Beachcombing in France:
While on vacation in South West France near the Spanish border I cycled to a beach at the remote end of a wide Mediterranean bay.
Leaving the bike I walked the last four hundred yards or so along the shore to where nudists, both male and female, lay spread-eagled in the sun. I shed my shorts and strolled slowly along enjoying the view and very much aware of the warmth of the sun stimulating my cock.
I passed the odd couple laying close together and touching, It was all very pleasant, but just when I was thinking that I was unlikely to see any action, my attention was caught by movement up at the back of the beach.
I looked up the wide stretch of sand to where the beach ended, and close by the reeds and bushes and saw a couple. She was kneeling on all fours and her largish tits were swinging as he pushed into her from behind.
As I walked towards them, my eyes fixed on her swaying boobs and prominent nipples, my cock grew and it felt to me as it had never been harder.
They both smiled as I approached and when I knelt down upright on my knees, close by, I was able to enjoy an uninterrupted 'side on' view of them while they could see my highly visible erection.
He pulled out and exaggerating his thrust, made sure I could see. He was obviously enjoying showing me what he was doing.
She loved the extra attention and licked her lips as she watched me stroke my cock appreciatively.
There was a pause for a few moments as a naked family approached and passed by. This caused me to pull up my knees and hide my raging erection. Meanwhile the guy just slid in tight behind her and held her close, his hands cupping her tits. (I could see from her face that she was feeling his cock still active inside her.) The little girl of the family looked at them as they walked by and tugged on her father's hand and whispered something to him. (he also looked towards them and I could have sworn I saw his cock twitch.)
