You little toy of mine... You're very hard now, don't you! Give some edges then...
EDGE!...
EDGE AGAIN...
AND AGAIN...
OH... EDGE TOY, NOW!...
EDGE... and relax for about minute.
Are you dripping pre-cum, toy? Nice... Very, very nice...
Now start some slow strokes and make 100 of them... and no edges, not a single one or you'll get some slaps on your full balls. Are they in some kind of pain or maybe a blue color? No... Too bad!
Give another 25 really fast strokes; get near the edge and... continue!
