My Little Friend

There can't be more differences between two guys fucking, than the pair of us.
I'm six foot two, forty six years old, muscular and I have an eight and a half inch cock.
Samuel, Sam, is nineteen years old, five feet two, slim and has a four inch slender cock.
When having sex, I literally throw Sam about and bounce him up and down on my fat cock.
What's really weird and at the same time a real turn on, is when I'm fucking Sam in the missionary position, I can see my cock, which curves upwards, pressing up against his stomach.
He might be small and very effeminate, but Sam can't half take a real hard anal pounding. Something other more taller, beefier and more muscular guys I've fucked, haven't been able to handle.
I'd love to make my neighbours son a permanent fuck slut, but I don't think my wife would approve.
