I was secretly edging at work last night and was pushing the edge well enough that it was quite the teeter totter... I'd let myself feel one orgasmic contraction then do everything in my power to fight if back. I'd tighten up my kegels and squeeze, as the feeling passed. Then just before it went away I'd resume just shaft stroking to bring me right back to the edge again. Over and over I played as everyone left for the day. I was alone at the counter as I crested the edge again and I heard a car door close. I quickly zipped up and in walked a customer. Female, attractive, you know the hot mom type... I stood pretty closely to the counter as we talked so she didnt see my harden through my pants. That's when I felt that oh familiar feeling grow in me. The urge... the need filled me and and I felt my prostate begin to throb and tighten and that's when it happened. I felt that electrical charge fill my veins as my cock filled my pants with all my cum. I felt it run down my leg as I wasnt wearing any underwear as a chat buddy, had requested. As it ran down my leg, I could feel it soak me as my cock pulsated over and over. Every nerve in my body wanted me to gasp and whimper as wave after wave of orgasmic bliss crashed over me. I was speechless as my customer was oblivious to me cumming. She carried on and then as the last pulsation hit me, she asked me to come out to her car and give her my opinion of her project. I did as I was asked with the obvious cum stain soaking through my pant leg. At one point she looked down and noticed the wetness but didnt way a word. While hot and quite awkward, the humiliation of the situation was very intoxicating and got me ready for round 2.
