I'm 35. Friday my wife and me arranged for Katie, our 18 year old neighbor to watch our 3 year old while we went to a party.
I left around 10:00, as I had an early flight to catch - my wife stayed at the party.
I was met in the front yard by my mutt, so we played for a minute and we walked around the block, and came up through the small patch of woods behind my house.
I noticed the deck light was on, and I saw Katie and her boyfriend climb, naked, out of the hot tub.
They went to the sunroom, and he laid on the chaise lounge. She straddled his face, and started sucking his cock. Mine was getting hard by now.
She slid down, and mounted him, her back still to him. She started thrusting, and I could faintly hear her moans.
By now I was stroking my own to her every movement.
Just as she threw herself back in orgasm, I shot my load.
I took the dog, and went around the block for a longer walk, and when I went into the house, he must have been gone and she went to bed.
I feel kinda perv for watching, but damn, it was a hot show!
