The weather was great early in the morning. There was no one in sight at the sewage ponds - so I stripped down to my tights. Already on the way there by bike - I was horny. Then walking around in nylon and grabbing and stroking my cock - it made me more and more eager to jerk off and squirt. But I always had to be careful that someone didn't come by. It's very erotic and COOL to masturbate outside. Unfortunately, often alone.
