My first orgasm

Again I lay back and started stroking gently, my fingers gliding up an down my shaft. I must admit it was very pleasurable and this time a burning sensation was starting to happen in my groin. Sweating, hot, wrist aching, groin throbbing I continued until almost exhausted I couldn’t go on anymore. I lay back in the bath trying to catch my breath and regain some composure. After several minutes I climbed out of the bath dried myself off and stood looking in the mirror. My cock still semi erect and that irritable aching in my groin had not gone away. I wrapped my hand around my cock one more time and again stroked my shaft, faster and faster, my heart pounding, groin aching, the tip now very sore and had to keep putting water from the tap over the tip.

Then from nowhere a sensation in my groin started to grow. At first a small burning, throbbing sensation getting faster and building. My cock was on fire, my groin felt like it was about to explode, my head spinning, my legs shaking and then it happened. An incredible explosion of sensation, my mind spinning, my balls contracting, hips thrusting forward in a primeval dance of their own. Feeling as though my balls were trying to exit through my shaft, my heart climbing out of my chest with wave after wave of the most wonderful sensations coursing through every piece of my being I struggled to stand and slumped to the floor in a jelly like state. It took around 15 minutes to finally stand and regain control of my senses. What had just happened? I must have just come, I have not stopped coming since, 30 years later and still stroking.
