If ever I have a problem getting off on watching porn, I still think that ones imagination is the best of all.
I always refer to my regular fantasy whereby I am young, maybe aged 11-13, when I am getting erections and just starting to produce some thin jets of watery semen. My fantasy is that I am tricked by some older girls, or their mothers into their bedroom. I am bullied, captured by them, they grab me and take me into their bedroom. They strip me naked, and laugh at me, pointing at my small underdeveloped testicles and my little penis. They push me onto the bed, some of the girls hold my arms down and the others sit on my legs. They start shouting at me, I can hear them talking about my little penis, they want to know if I can get erect and ejaculate. One roughly grabs my little penis, and rubs it, it erects, they take turns in forcing back my foreskin, pulling it tight back, they laugh at my exposed glans, they poke it with their fingers, they take turns in pulling at the taut banjo string at the back. They laugh at the shape and colour of my glans, calling it a funny red mushroom. What makes me cum,is that they want to cut off my hard penis. They threaten to cut off my hard cock unless I ejaculate. They take turns in roughly masturbating me, harshly, painfully, until my little erect penis throbs and spasms in an orgasm. An intense, dry orgasm, until I squirt my first jet of thin semen. They laugh, poke fun as they continue to masturbate me over and over.
All the while I am thinking this, I am roughly masturbating myself, jerking my foreskin back hard, as they would be doing when I was a young, pubescent boy.
