My longest wank was my best orgasm ever! Remember it like it was yesterday.
In my late teens, a brand new VHS copy of a porno from a mate, parents out for the night. Wanted to watch all the movie so I had to keep stopping (now know it is called edging).
After watching the flick flick (around two hours), rewound to my favorite scene with only one intention... I came and came and came to a big titted latino lady getting done in all directions by a big black guy.
Have never been able to repeat those intense feelings and that amount of cum since. Believe me, it has not been through lack of trying!
