One of many beach experiences.
It was a time not long before we were married and my fiancé and I were staying with my folks in their holiday home in Donegal. We still had separate rooms in those days and little opportunity to be on our own.
This one particular day we were at the beach with my dad. It was a great beach tucked away over a couple of fields and overlooking the beautiful Mullroy bay. We all went for a swim and my dad was the first to head back a shore. We stayed a little longer fooling around and splashing each other in the water.
Then Sheila pulled me close to her and gave me a warm, lingering kiss. I could taste the salt from the sea on her lips and the sensation had the desired effect on my penis despite the cold of the Atlantic breakers.
My dad was still walking slowly back up the beach and I reached down and rubbed Sheila's crotch through her costume. She lay on her back for a moment and pulled me closer with her legs wrapped around me. I rubbed some more and she started groaning. Evidently, being without sexual favours this last week while staying under my parents' roof had made her very frustrated. It wasn't long before she came with an audible shriek.
My dad was drying off up by the dunes now some way off. Sheila smiled wickedly and dived under water and between my legs. She pulled my trunks down and tugged on my hard-on a couple of times before bursting to the surface once more and laughing. I hugged and kissed her again and then she broke free and reached down and took my member in her right hand. I stood there with my back to the shore up to my chest in water while she slowly pulled my penis up and down while treading water the whole time.
While I was very aroused the masturbation seemed to last for ages, I suppose because of the effect of the cold water. Eventually, Sheila's hand movements speeded up with some splashing around and I could restrain myself no longer. As I came she kept going and I had one of the longest lasting orgasms of my life as wave after wave of emotion overtook me and I pumped endless streams of cum into the sea.
It was an amazing episode and one of my most enjoyable sexual experiences before we were married.
