I was piloting a small motor boat, the deep blue sea, vast and yet calming.

On the cushioned bow of the boat, I caught my wife prising her bikini bottoms down until they were discarded. Opening her legs she smiled at me and then slipped her finger along her wet slit before beckoning me towards her.

Everything changed when the hand on my shoulder arrested my enthusiasm.

"It's not you she wants, it's me," whispered her friend in my ear.

I watched, avidly curious, as they ate each other while my erection bounced with the force of the oncoming waves.
