They were mixed sex and were bigger than normal to give campers somewhere to change in the dry. Being the voyeur I am I was praying for some spotting...during the weekend. When we all went to watch a band play I snuck back and reconned the cubicles of the toilet block nearest to our camp. Sure enough - there was a tiny hole in the join of one of the cubicles that i managed to enlarge slightly - I had struck gold. It was too dark to see at night, but i went I back on day 2 when it was raining. I opened the back door and Charlie just walked in as if he lived there. Stuttering I blubbered out ' ... what you doing here, what you want? ... ' Charlie just smiled as he reached out and stroked my chin saying ' ... It's my turn now, you all clean and ready for me I know! ... ' I tried to tell Charlie ' ... my folks may come back ... ' Charlie just smiled and chided ' ... then we better get busy before they get here! ... ' Charlie took my right wrist and pulled me down the hall to my room,. " I loved the why she begged I put the tip of my finger in her and wiggled it around "Beg me" I wispier in her ear, then playfully sucking at her neck. "No, please Joe don't make me beg I really need to cum." I took my finger out to let her know I was being serous she turned around to face me, I could see the lust in her eyes, she sat on the pool table and wrapped her legs around my waist and grinded my dick she moaned again and threw her head back. "Oh Joe please fuck me!" she yelled I. “It gets so dirty.”“Yeah,” he said.I shuddered, watching his muscular body moving beneath his t-shirt. He grunted and dragged the right side of the couch out with ease. He got behind it, facing me, his biceps bulging, and shoved it forward.I almost swooned with how gorgeous he was. Young men were so sexy. And my son was a hunky stud.“There you go, Mom,” he said. Then he glanced down. “Huh, not as dirty as I thought.”“Oh, well, I do keep a clean house,” I said, hoping he wouldn’t realize I had.
