Today is Monday and it is 12:15am. I am at work as I begin to write this. I have just returned from the restroom where I played with myself like I've done so many other times before. I went into the stall and pulled my pants and undershorts down. Then I sat down on the front edge of the toilet seat and spread my legs. I placed my right hand over the end of my penis in the cup fashion and started pulling on it. At first my penis was soft and flaccid. But it quickly responded and grew firmer as I played with it.
I sat there masturbating for several minutes while thinking erotic thoughts to aid my endeavour. As I pushed and pulled on my penis shaft I grew more and more aroused until I was just at the brink of having an orgasm. Instead of pumping my penis until cumming and shooting my semen into the commode I stopped short, leaving it standing there unfulfilled. I got up from the commode, pulling my pants back up over my semi-hard penis, and came back here to my computer where I am writing about it now. As I'm writing I am rubbing my penis head through the fabric of my pants. It feels good. I may just go back into the restroom later and fulfil my penis' longing.
(A little while later) I did! I had a great cum too!
