My seven-year-old son has a tight foreskin, and I have to do stretching exercises on him, per the urologist's advice. I've been doing that for a month now. Every day, I rub baby oil on his penis and pull his foreskin back and forth. Each time, his little prick gets hard, and pretty soon he starts to moan, his eyes rolling back. Many times, I feel it pulse madly in my hand. I don't mind that, it's a normal body reaction. On two occasions this month, he asked me if he could sleep in my bed because he had a bad dream. Both times, I could see a bulge in his pajamas when he asked me that. I let him. Soon, I would feel him hump my rear. Each time I just pretended to be asleep and let him do his thing until he was satisfied. He's my little cutie pie.
When I was 6 and my brother was 5 we still would take baths with our mom. She taught us how to keep our foreskin and penis clean and would get us to kneel in the tub and she would pull back on our foreskins and “wash” us. Inevitability we’d both get hard and she played with us till we got soft. Basically I think she used to give us both a wank. Which then turned into something we would do with each other for quite a few years.
