When their bodies were pushed together, I sighed out loud at the beauty of their coupling. His hips began to move up and down as he thrust into her, and hers moved in harmony with his. They fucked while I watched for forty minutes until he came in her and withdrew, and she moved to take his wet and softening cock into her mouth, sucking it lovingly and swabbing his wet organ with her lips and tongue while he grimaced and and fought the sensitivity of his post orgasmic cock.
They were positively gorgeous as they recovered from wonderful sex in the Pacific sun on the foredeck of our boat. Silently I left them on the deck and went below. I had seen them fuck, and I had watched them come together in an elegant coupling of sexy, gorgeous young people having marvelous orgasms, loving one another as people should. I had seen my wife fuck another man with love and caring, and I had been able to enjoy it with them and feel the heat of their desire.
It had been a good day, and I had seen what makes people need one another. She was my wife and his lover and I had evidence of both. Oh what a lovely day for sex.
