I was bored with the fire, and thinking of a good reason to turn in early. Tom was poking the burning logs with a broken branch when my aunt suggested... we go hit the showers. She said we would be packing it all up the next morning, and she did not want to smell us in the car for the long ride back to their house. Tom and I looked at each other, shrugged, and headed to our tent. We grabbed our toiletries and towels, and headed toward the cinder block building at the top of the hill. The shower. I then stand up and slowly take off my clothes in a burlesque striptease, throwing my little cot-on panties to him and he sniffs them and puts them in his mouth. I tell him that he is a dirty old man, and he says, yep, and this dirty old man is going to make you bleed and scream for mercy. I said, bring it on needle dick, and don’t know where that came from. He stands up and turns around and bends over and spreads his ass cheeks and says lick my ass for a while and then see if you can stick. I felt his anal muscles clenching and unclenching around my cock.I withdrew a couple of inches and pushed back in. Then again. And again.I established a slow and steady rhythm and I swear his ass welcomed each thrust. His butt pushed back against me. His breathing quickened, he gasped and lunged into the pillows. I sensed that he ejaculated. The clenching of his ass around my cock confirms his cumming.I reached under and latched onto his cock. It was wet and slimy with cum.I continued to stroke. She held my chin up and rubbed my cock with one hand and kissed me saying I’ll be right back baby and proceeded up the open staircase to the second floor where our bedroom was located as well as the spare room aka the playroom. I could hear her milling about and could only imagine what she was doing. Every once in a while she would call down to me are you still behaving waiting like a good boy she would ask, yes I replied ok good I’ll be right there I heard her walking to the bedroom door and.
