When my son was around 3yrs old I let him watch me jack off and he'd giggle as I'd fill his little hands with cum. Then shortly after he tasted my cum and he seemed to like it because after he'd hold his mouth open for me to just cum directly into his mouth. That turned into him sucking on the head of my dick until I'd fill his mouth with my spunk. By time he was 4yrs old I was showing him guy on guy videos and telling him to suck my dick like he see's the guys going, he soon turned into a great little boi toy. One day I felt bold telling one of the guys that I like to suck off and he was all for letting my son suck his dick. My son is now 8yrs old and can take at least an 7" dick up his ass, balls deep.
