Beyond the fact that I had never heard my wife use the word 'cock' before, and beyond the fact that she had just complimented the size of another man. I was already past breaking point. I erupted, as did she, her pussy tightening around my dick as I came. She moaned loudly, and then we heard Bob.
"Fuck yeah, give her a proper fucking." His words escaped through grit teeth. We both looked over to see him erupting, rope after rope of cum exploding from his cock, his massive balls contracting tight to his shaft as he came. He groaned as he had his orgasm.
Eventually we all came to a still, and silence suddenly occupied the patio. The absurdity of it all caused me to erupt into a laughter, which was eventually mimicked by Anna, and then Bob.
"Alright neighbor, I think we're heading in for the night." I said, exasperated.
Bob, coming to his senses, and concealing himself in his shorts, spoke.
"Jesus. What the fuck just happened?"
Anna laughed, and I replied, "I have no idea."
