But even after sleeping around for the better part of a couple of years, that did not prepare me for what would happen one weekend when my daughter's ...friend was spending the night.That afternoon my daughter's friend Shannon came over. We'd known her for about six months. She had just recently moved into town and went to the same school as my daughter Karson. Shannon was about as different as any girl in my daughter's grade as I'd ever met. Very outspoken, not afraid to speak her mind, and. . it was empty. Heading downstairs to find his mother cleaning up after making breakfast, the question occurred, "Where's Sandy?"From behind his newspaper Dad said, "She jogs two miles every morning. You didn't know that, but you had better learn her schedule, so you don't piss her off." Was she upset?" Actually honey," mom said, "she was beaming as she left with her bottle of water. You could use a jog yourself; you're a bit chunkier than when you left here four years ago. She should be back. When the lights came on, Jake found himself starring at his own body. "This can't be happening," Jake protested as his own strong arm dragged him to bed for the best night of sex in his life.After which they laid naked except for the thin bed sheet covering them. Harriet in Jake's body sat up with the laptop and tried to bring up her husband favorite stories. "The site stories have disappeared." Harriet said curiously. Jake was too exhausted from the sex to notice that the laptop wasn't even. She fell on the bed to move hips wider to the sides. Her buttocks gave me full access to her ass. I realized my elderly mother-in-law was a big anal sex freak. Our first sex was apparently just a foreplay to more passionate games. I decided to do the utmost to make her feel sheer bliss.My tongue moved between her buttocks and concentrated the entire caress on her hole. She was moaning and swaying her pelvis. Her hands were fondling her boobs or spreading the buttocks wider impaling the ass on.
