My name is Danny. I had just celebrated my eighteen birthday, so my parents decided to treat me. They had rented a lakeside property for a long weekend so we could spent time together. My dad is a businessman and is always on the road. This weekend he promised there would be no distractions. Guess what? Sure enough, some business came up so my dad told my mom and I to go ahead and he would catch up and meet us there.
My mom, whose name is Becky, and I made the four hour drive to a beautiful lakeside resort in the mountains. There were no other people around as far as I could see. Mom and I got to the cabin and got settled in. The first thing I wanted to do was to take a swim. I went into the bathroom to get changed into my trunks. I had partially opened the bathroom door, when I saw my mom stripping down. She was naked before me as I peeked out of the bathroom. My mom had dark black hair and a hot body, I must say. I knew I shouldn't be looking but I couldn't help it.
She picked up her bikini bottoms and her top and quickly slipped them on. I made a rustling noise so she would know I was coming out and she got her bathing suit in place in a flash. We walked down to the docking area and we both dove in. The autumn water temperature was warm and we swam laps in a lake that we had all to ourselves. We spent maybe an hour in the water when my mom said she was hungry and was ready to go back to the cabin.
As we walked back I kept looking at the wet bikini clinging to my mother's body. Her nipples seemed to be so erect and I could tell they were plenty big. Her slit was also showing through the wet material. I hate to say it, but my cock was stirring a bit in my trunks. As we walked back my mom was joking with me. She was saying what a big boy I was now that I was eighteen. She would poke my arm and I would do the same to her. We were laughing and carrying on when we entered the cabin.
For some reason we continued to touch each other in a joking way once we were inside. Maybe I was feeling my oats right at the moment or maybe I was just horny.
"Do you really think I am a big boy?" I asked my mom.
I stood right in front of her and pulled down my trunks. My cock sprung out and I guess I was half erect.
"God Danny, what are you doing?" My mom asked me, "Put your trunks back on."
