He told me to suck his balls as I stroked his cock, and when I didn’t move right away, he leaned up and put his hand behind my head and pulled me in...o his big balls. The manly, musky smell was intoxicating, and I began to lick and suck his massive balls and scrotum. The taste of his genitals turned me on even more, and the precum was also flowing down to his nuts for me to taste. I even tried to get both of his balls in my mouth at the same time, but they were just too big. He released my. He pulled away to watch as my sister kissed my mouth and helped me out of my shirt and bra. She started sucking one tit and Ron sucked on the other. I was in heaven and it was just about to get even better. I couldn't believe my sister was actually gonna share this man with me. I always found him attractive from the moment I met him.

The next morning I went in to wake her up for breakfast. I said her name a couple times, and she just rolled from her side to her back but didn't open her eyes. I tapped her shoulder, and she sighed but still kept them closed. Finally, I just grabbed the bedsheet covering her and pulled it off while she moaned in protest. I was shocked to see her shorts in a ball on the bed and her uncovered pussy in plain view. She didn't even move, so I assumed she didn't remember she had taken her shorts. I wept into my pillow, I fell asleep naked below the waist on top of my sleeping bag.In the morning, Joe woke and masturbated squirting his cum onto my face and hair, he then dressed and went to the ablutions block for a shower leaving me covered with his cum. The rest of the camping weekend was the same after we went to our tent. Joe and I have been secret lovers for over twenty years, he still dated stunning girls, but we have a special love, I am his personal plaything, it is a role I enjoy.
