This story starts when I had to move from one place to another. I had my sleeping room and living room packed with boxes and all kind of other stuff. I slept in the living room because there was no other place to sleep. I had taken one week off from work to pack and move.
One morning during that week I woke up, with an urge to pee. But I didn't want to go. The bed felt too good to go out yet. At the same time I was quite horny. When I was ready to go out I went to my sleeping room to grab clean underwear. Still feeling horny, but too ashamed to rip my clothes off and wank myself. But I wanted it so badly. I took off my pyjamas and stood there naked with in one hand my clean underwear and the other a quite stiff boner.
What to do now, with still the urge to pee. I slipped my underwear along my ballsack and oooohh that felt so great. My erection got stronger and stronger. I now had a huge stiff boner. I couldn't hold it anymore and stepped into the shower and let the flow of urine come out. What a relief. That all took a minute or two. I was thinking my erection would also decrease, but that wasn't true. It was still staying up after the long pee. I still had my underwear in my hands and I rubbed it again along my ballsack and after a minute I couldn't hold my ejaculation anymore and wanked three times. I was shaking all over my body by now. That was the greatest and strongest orgasm I ever had.
Of course I cleaned up the mess and went on moving.
