Spontaneous Ejaculation

In history class i used to sit opposite this really hot girl who always war short skirts. One lesson i sat there with a raging boner fantasising how it would be to kneel between those beautifull legs. My thoughts got a bit carried away and before class was finished i had made a nice mess in my undies.
 
Yep I get spontaneous ejaculations quite often, especially if I don't jerk off for a few days. It can be quite embarrassing if people are around, and more so when I only have shorts and/or boxers on with no briefs or trunks. I've had many many embarrassing moments when I've had an erection that sticks right out through the side of the shorts and i'm not able to contain or hide it back in coz its stiff and big, and to make it worse it starts squirting out my juice, usually in higher volumes and more spurts than usual because I haven't jerked off for ages.
 
Long time ago I was reading the autobio of Dick Cavett, and I remember he mentioned his first experience involving sex was the gratifying sensation he got in his crotch when he was sliding down the clothes pole.
