For me it's one of the best feelings in the world bruh, everything about it really man.
During a long day at work my sack starts to get heavy and I begin to get that wanting feeling to get home to my wife and some good pussy, the anticipation once I'm home waiting for that moment when we can get a chance to get sexy. Her taking my meat into her hands and caressing my balls is awesome as I begin to get hard, that tickle as the precum begins to well up and ooze out my dick as she plays with me is great while I'm going to work on her pussy with my mouth and hands. Once we're down to business that feeling as my heavy balls stir and the pressure slowly begins to build getting ready for busting my first load is awesome, all building up to that moment when I just can't hold it any longer and everything tightens as my cock thickens and begins to flex and then that fantastic feeling as all my seed forces it's way up through my shaft is just the best. I'm a pretty heavy cummer as it is and blowing that first load is an immense feeling as my body pumps out long rushes of cum up through my cock making me shudder, my cum can be pretty damn thick and lumpy I swear I can feel the lumpiness as it all rushes up through coupled with all that pressure being released in long spurts. Then of course that feeling of satisfaction and relief as I'm wringing out the last few spurts sometimes getting the surprise of an extra rope or two come surging up through just when I thought I was done, pure bliss bruh, pure bliss.
