I masturbate after 3 days

I relive the moment I masturbated after 3 days. One of my most pleasurable wanks I'm 19 years old and I masturbate very regularly, my record without masturbating is 5 days. The other day I challenged myself to break the record. The first day went well, no problem at all. The second took a bit more effort because I was getting excited. The third was too much and it had to happen. I started watching porn and my cock was about to burst bigger than ever, my balls hurt, I kept watching porn and got hotter, feeling like I had swollen balls full of semen and on the verge of exploding. It was night and I tried walking into the living room but couldn't get rid of the erection and couldn't take how excited I was, so I quickly went to my office and started the job. I sat in my chair and lowered my pants a bit, leaving my young cock and inflated balls exposed, stretched and opened my legs a bit and started wanking myself rapidly with great excitement, the pleasure I was feeling was incredible, a warm taste in my cock after almost four days without masturbating. I started thinking about milfs in stockings and skirts lifted showing their hairy pussy, and that got me even more excited and started giving me spasms in my cock and body, it was the sign that the semen had almost finished its journey from the balls to the cock and was about to come out. I kept going for a few seconds more and couldn't hold back anymore, I came, felt a tingling sensation at the tip of my cock and got up, then finally what I needed happened: I started coming, hot semen started flowing out of my cock as I moaned with pleasure from spreading my seed. When my cock stopped shooting cum, I sat down extatic and relaxed with my balls well emptied. I stayed there for a good while feeling the wonderful sensation of having cleaned all the channels of my reproductive apparatus and having emptied my balls to the point of explosion. Since then I've been... masturbate every 3 or 4 days to relive that incredible moment. I wait for a couple of days until my balls fill up with sperm and then I empty them with great pleasure.
