Like when you are almost to cum, your wife walks in and you squirt down the inside of your jeans leg, acting like nothing is wrong. She looks at you funny and you pretend to be tired and put your head down...and squirt a couple more times.

Been there done that.

Would love to be so turned on that my cock just starts spurting cum out of the blue.

Cocks throbbing involuntary now, so who knows what might happen?

So turned on thinking about this happening

Wife was driving home from a trip. No sex for seven days and I was extremely horny. Thought I was going to have one in the car cock was going crazy. I almost think I had to talk myself out of it.

Sometimes find it's the best way to orgasm hands free watching porn, don't always have to stroke but naked I just let it out. Been a few times in public, on buses or walking almost came. I quickly find a public toilet or stop looking, summer hot days

When wife is away I get fully naked at night, have some drink and watch sexy movies. For few hours the cock is very hard. But later on the cock goes limp but horniness rules. Suddenly at some point the cock starts ejaculating without touching.

sounds amazing! So jealous! Would love to just shoot my load with wife sitting next to me.

I don't think I've ever had a full blown ejaculation involuntarily, but I've had precum come out of my cock when not masturbating, many times. I can usually feel it going into my boxers....it's an amazing feeling when it happens.

I experience three types of involuntary ejaculations.

The first is when I have edged for a long time, but had to stop before cumming. That occurs when I'm pissing, and I notice that thick ejaculate is dribbling out of my cock. There is no orgasmic feeling.

The second occurs when I try to bring myself to the edge before ejaculating, and stop too close to the inevitable spurting. Without hand movement, the cock starts pulsating, and it happens, although I had wanted to delay it.

The third happened in my youth more, when I was on a bus going to school or sitting in class, and the cock just comes alives and shoots. When I first went to adult theaters, I also had those, before I learned you could expose your cock and enjoy yourself.

When I was younger walking or even sitting in certain positions would cause my clothing/underwear to rub my cock and cause a hard on. Even if I repositioned myself, once the hard on was raging I would often have an ejaculation without manually rubbing myself. I had a lot of occasions where I had to explain the wet spot on my pants. No that I am older, spontaneous orgasms like that do not happen, but I still love to wank!

Im sure it was inconvenient and probably embarrassing. Wish it was that easy for me now.
