#270491 - I decided after a minute or so to see if I could just get a feel of his balls from behind, as I inched my hand further down his bum, I could sense that his legs were parted enough for me to get my hand between, I was almost there I could feel the heat coming from his body through his briefs , I was almost at full stretch when I felt his balls for the first time, my cock was on fire, I stayed there excited to be touching him , not wanting him to wake or move . We were a family containing 4 children , 2 boys 2 girls, we lived in a three bedded house so we had to share rooms, our room was only big enough for a double bed so as two teen boys growing up we were used to sleeping in the same bed and I hadn't thought anything unusual about it as we had done so all through our lives. He felt as big tonight as he did last night, his cock arched over his balls forcing me to hold him tight so I could still feel all of him.
