We both emerged from the water with a sharp gasp, as I circled in the spot around the water I was grabbed again by her, her strong legs wrapped around...my waste and her arms around my head as she pulls me in for a passionate kiss, pressing our wet naked bodies tight together.I felt her legs unwrap and then a sudden kick against my own legs sent her flying through the water away from me and back under.I didn’t know it yet but this was a game, she was the shark and I her prey.Time and time again. She was a widow, never had c***dren and never wanted any. Her husband died suddenly when she was 40 and left her well off, he had a large insurance policy. She would never have to work. She would from time to time go out to a bar. When she did she always dressed like a slut and would tease the young men at the bar and sometimes she would take a lucky guy home with her and fuck her brains out Harry and Rob always went to the same bar, they were both in their late 20's. They were not the kind of. Then her fingers were gone, I was starting to feel empty and disappointed when suddenly I felt the tip of the "cock" touch my puckered ring, I tensed waiting for the pain of pleasure that was about to invade my body, Slowly she pushed the head against my ass, I could feel my ass ring slowly stretching as the "cock" slowly entered me, suddenly it slipped in, I moaned as I felt my asshole release as the "cock" slipped all the way in, "Oh god," I yelled," it's in, you are fucking your son in law. I thought it would be better if I lay on one side and tried to poke within her ass more thoughtfully. Since I had just jerked off, I was totally spent and didn’t feel like cumming. Bertha, on the other hand, was mounting into another orgasm prompted by my stroking of her clit and I paid attention on how my rod slid in and out of her asshole. She began to moan loudly and cummed on my fingers. As I felt my cum closing in too, I quickened my rhythm, saw the woman wriggling, I cummed into her.
