Nicely gooned man cums as he finally feels ready for release. (Point of no-return 0:47 ; ejaculation 0:53)
Notice that he keeps stroking his shaft during and long after his orgasm. For the uninformed, this will appear surprising as the cock head becomes exquisitely sensitive as soon as the orgasm is triggered. This man, however, knows that sustained stroking for as long as this hypersensitivity persists magnifies the orgasmic experience. You can see him squirm as he rubs his sensitized cock head (1:03-1:14), in effect multiplying by 3 or 4 the duration the orgasmic experience.
