Jerked off to milk dry

I jerked David off just to I could milk the sensitive head of his dick after he came. This straight guy has the most sensitive cock after her shoots his load, but he always seems to forget that I like to milk him dry after the cum shot and he never sees it coming. So I tied him to the spanking bench and slowly worked him up until he was rock hard, then I slipped a fake pussy over his cock and slowly brought him to an intense orgasm. As soon as he finished shooting I started playing with the head, which protruded from rubber pussy as if to isolate it from the shaft for focused stimulation. I jerked, stroked and polished his head for a full 3 minutes while he writhed in agony, cursing and begging me to stop.
