I generally fetch an adequate supply of toilet paper to have by my side beforehand, then I start, usually quite slowly, gradually working it up and getting into it...if I feel I'm in danger of finishing too soon, I'll slow things down to a snail pace, still going but with just the bare minimum movement, before very gradually working it up again until I know I'm ready to finish. Depending on the intensity of the climax, I sometimes end up violently lurching forward in my seat before letting my chair settle back down, holding onto the shaft without stroking any more with my eyes closed, savouring the moment and the thud of my increased heart rate as I feel my penis transitioning from erect to flaccid in my hand. Being the Asperger's/OCD harbouring freak that I am, one stipulation is that I musn't view the arousing material again in the immediate aftermath of finishing, so this involves me staring down to avoid looking at the screen while hammering Alt and F4 until I'm sure all windows will have been closed...again depending on the intensity of the finish I sometimes knock my table mats askew, so I have to readjust them too. Strangely, though, despite these things being important, I often neglect to wipe down when I'm down which results in stained boxers yet this doesn't bother me.
