My favorite way to jack off is to slip on a wide stainless steel cockring behind my cock and balls. Then I stroke my cock from head to the base real slow making sure to give my balls plenty of attention.
Once my cock is rock hard and twitching ready to cum. I put on my adjustable nipple clamps. I have them set at the point of almost being completely closed! The sudden pain almost makes me shoot my load! After I catch my breath I start to stroke my cock again really slow. Milking my cock with a firm grip. Lots of times I think about some hot guy or girl that I've seen during the day.
Buy this time I'm ready to cum! I start to really give my cock a good work out. I deep stroke my cock hard from the head all the way down to the base. My balls slam against the cockring giving me an extra bit of joy. It usually doesn't take long until I cum all over myself. Sometimes I flip my legs over my head and give myself a facial imagining that some hot guy is shooting his cum all over my face! It's great! You should really give it a try.
