The 2nd day camping. My family got along with several other families but I was the only person of my age around the other families were couples. I met the guy that masturbated in front of my on my first day( I never said anything) his wife was nice and so was he. My family was the only one to have their daughter with them. I felt like an outsider. Everyone was taken no boys ot girls for that matter. Bored again. The only thing to releive my bordom was walking thr trails from our campsite to the beach and bathouse at night hearing people fuck. I am not a pervy girl but it did cure bordom. I waleked upon a lady getting fucked buy a man she was bent over a pick nic table. I rubbed my pussy underneath my bikini bottoms watching. He was kinda hot older maybe my dads age nice body. When the campfire moved in a paticular was I was shocked to reconize the lady( it was my mom and that was definatly Not my step dad.) I cant believe my strict mom was like that. I couldnt believe I kept masturbating wathching. She was getting fucked hard Then I noticed another man in the dark behind her. I thought it was my step dad. I was like oh she he is going to be pissed. But The guy fucking my mom started to cum and moved away the guy in the back ground took his place and it was not my step dad. My pussy was dripping I stepped on a twig as I backed against a tree and so I walked away heading tward our campsite. My step dad was not there but I saw him at the site next to ours. He was getting his dick sucked by the wife of the guy that masturbated in front of me. I will admit I didnt realize my stepdads dick was that big. I ran back to out campsite and layed there masturbating. I had 3 orgasms realizing how much sex was happening. A while later my parents got back him first then her a few minutes later. We sat around the camp fire he told ghost stories and roasted a few marshmellows for fun. I fell asleep thinking how strange this all was.
