Her pussy tingled as she couldn’t take her eyes off her son’s beautiful erect cock. His large hand was slowly stroking the full length of his rigi... member. Every other stroke upward, his hand circled around the huge purple cock head. He was lost in his lustful gazes as she heard the girls splashing about the pool. She quietly proceeded across the room. Facing out the window watching my sister’s perfect little hard body and her sexy friend Jennifer lounging on the chairs, I suddenly felt my. We lived in the same area, so we agreed to share a cab, I had told her earlier that my family were away for the weekend, and I would be heading home for a meal for one lol. In the cab, she asked if I wanted to come in for a bite to eat, as she had made a casserole, for herself and her daughter, and there would be plenty left. I readily agreed, and followed her to her door, not realising my life was about to change forever.When we got indoors, she showed me in to the lounge and said I should. Reaching over, I ran my hand up his shorts leg and grabbed is cock out of his shorts telling him it was ok to have this reaction and for me to show him how to relieve it. I stroked it maybe ten times and he came with such force his jism hit the ceiling of my car. He ejaculated a very copious amount, especially on my hand. This whole time he was still kneading my nipples and tits. I looked around to find something to wipe my sons cum off my hand, not seeing anything I just licked my cum. The off-road park we were at is a very popular one and it's mainly mountain riding. I was just about to ask Andrea ( my wife ) to go for a ride when a serious Rock bouncer pulled up. Bouncer are purpose built buggy's that are tube chassis , big engines and monster tires. The guy got out and introduced himself as Mike, he wasn't a large guy , about five foot six but he was very polite. Andrea was bouncing around in a pair of cut off Jean shorts that exposed just the bottoms of her tanned butt.
