"Karen!" my Mom called. "Have you seen Stacey?"
My younger sister, Stacey and her boyfriend, Rob had left the small holiday cabin two hours ago on a hike. The woods were thick, and Mom was worried that they might have gotten lost.
"No," I replied, "but I'll go look for them."
Every year since we were kids my parents took us to the same cabin for a summer holiday. Even though I was in University and Stacey was in her first year of college we still came home in the summer. I was really looking forward to going to the cabin this year.
I got my shoes on and set out down the path to look for them. Stacey was lucky that Mom and Dad even let her invite Rob. It was her nineteenth birthday this week and it was Stacey's only request that she be allowed to bring her boyfriend on holiday with us. Mom reluctantly agreed.
I had been walking though the forest for about half an hour, calling Stacey's name out every few minutes. I stopped for a rest and noticed a small hill to the left. I decided to leave the path and climb the hill to get a better look around. When I got to the top of the tree-covered hill I looked down into the small clearing below and what I saw made my jaw drop. In the middle of the clearing, not a hundred feet away on top of an old grey picnic table was my sister, Stacey. She was laying there completely naked. Rob was standing in front of her. He too was naked, except for his hiking shoes. He stood there holding Stacey's long legs up around his shoulders. Rob was fucking my sister as hard as he could.
"Oh my God," I said quietly to myself. I took a half-step to the side and hid behind a tree. I had to look twice to see if it was really my own little sister getting hammered on that table. I stood there behind the tree, frozen to the spot. I watched in awe as Rob pounded away on my sister's pussy. With every thrust, the grey old picnic table moved, and every time it moved it squeaked.
Stacey's arms were stretched over her head and she held tight to the end of the table. She looked as if she would be knocked off the table if she didn't hold tight.
Rob began to slow down. He pushed two or three more hard thrusts into my sister's cunt and then stopped. He took a step back and made a gesture in the air with his finger. Stacey sat up, and like an obedient slut she hopped off the table, turned around and bent over it. She pushed her little round ass out for him.
Without missing a beat, Rob stepped in, and slipped his cock back into my sister and started to fuck her again from behind.
"Jesus," I said quietly to myself. I could hardly believe my own little sister was getting her brains fucked out in the middle of a forest by her boyfriend. "She's so innocent!" I thought to myself. Stacey was a pretty girl. She was thin, with small B cup breasts. She had medium length, blonde hair that she usually pulled back into a pony tail. She had a cute little round bum, and usually wore tight shorts. When she left the cabin she was wearing a tight, white t-shirt, red shorts, and a pair of sandals. There was no sign of any of those clothes from where I stood.
