A very heavy, very sexual encounter between my step-daughter's friend Katie and I occurred, long after my step-daughter and wife had gone to bed. The ...irst encounter, very physical and very taboo, led to another encounter the following night.The last sight I had was Katie walking up the ladder from the hot tub. I starred at her round teenage ass as she left the deck, closed the sliding doors and walked down the hallway to the bedroom she was sharing with my daughter.I should also mention that,. For months she had awaited this day. As soon as her parents left for work and her older brother went off with his friends for the day, Silvie ran to her room to dig out the small pieces of pink material with strings to attach it to her body.Wanting to get as much sun as possible, Silvie avoided using any sun block. She fixed herself a tall glass of soda and headed to the lounge chair on the deck of their pool. As she stretched in the chair she looked down at the bikini. The top had two. Maybe they were trying to figure out why she was now wearing the coverup. They may even be thinking the show was over. If so, they were really in for a surprise!When she reached her recliner, Debi announced, "I think I'm going to hit the pool - anybody want to join me?"Debi turned to see the boy's reaction as she slipped off the coverup. Their eyes popped wide open and their jaws went slack. Satisfied for the moment, she turned and walked to the edge of the pool and dove in. Several seconds. I began gently rubbing her clit like it was a little cock, and I'm jacking it off."Ummmm… Oh fuck yeah, do that, do that to me!" she moaned spreading her legs wider.That fantastic pussy of Michelle's began to respond to my touch, and I could feel a soft squeezing sensation on my cock as her pussy rippled and fluttered around my cock. It was almost as if her pussy was nursing on my cock, trying to get milk from it.It was incredible! Michelle laid on me, while I pinched and pulled and rubbed her.
