Keep the stories comming
I entered puberty at 12 with a bang. My body started to change almost overnight. I told my dad and step-dad about it and they already knew.
When visiting my dad, who was a carpenter like my step-dad, I would shower with him. I would soap up his body and give him a hardon and I would 'measure' my cock against his to see how much I grown. I measured my cock against both dad's cocks. They thought it funny, but it was very sexual to me.
I did this while soaping up their cock and balls and would jack them off while measuring cocks. They knew I wanted to jack them off but they didn't care. I jacked off myself also and had the most explosive orgasms a guy could get. I showered with them weekly until I was 15.
