Setting the scene: The family and I were on holiday, and I had just woken up and about 12, they had all gone down to the pool, and having woken up with a raging boner, I figured they'd be gone a while and I would 'deal' with the situation.
As I sleep naked I didn't have to take anything off, or beware of cumming on any clothing. I sat up and spat on my hand, then slowly massaged it into my cock, working up and down slowly to begin with. It felt so good first thing in the morning, sat there jerking myself off. I carefully dribbled more saliva onto my cock, and played with my foreskin, pulling it back and forth over the head.
After a few minutes of warming myself up I stood up and moved to the bathroom, as there's some hand lotion in there. I lubed up both hands and got to work, caressing my throbbing dick. I steadily pumped my hands up and down, faster and faster until I thought my pulsating member would explode with pleasure. I stopped, turned the shower on and and began to rub my bellend softly. With the foreskin pulled back and the lotion, I almost spattered the wall with my cum, but just managed to hold back.
Using two fingers I gently played with the base of the shaft, giving me an even bigger hard-on. The warm cascade of water felt so good on my cock that I couldn't help but resume pumping. There I stood with both arms working like pistons, until I couldn't hold back, I ran to the mirror and sprayed it with jizz, the long lines of my white seed coating it and the sink like paint. I squeezed out the rest of my cum, as the wonderful post ejaculation feeling takes over.
After a few minutes of sitting on the side of the bath tub feeling amazing, I decided to clean up, using my towel to wipe and soak up the huge amount of jizz on the mirror!
I stepped back into the shower, and washed off the sweat and lotion, I had been working hard! I then calmly and feeling way more relaxed, went down to the pool to sunbathe, without a raging stiffy. Problem sorted!
