While I have never had a spontaneous ejaculation, I do get uncontrolled/unintended erections when wearing speedos.

Last week I went to the pool and had arranged with the Married Guy to maybe hook up afterward in the change rooms. Usually I just wear jeans over my speedos and leave them near the edge of the pool but it was kind of drizzling rain so I went into the change rooms which are a little walk from the pool.

There were a few people in the pool swimming laps, but otherwise no one around. I pulled down my jeans, I was wearing my black ADIDAS 3-stripe speedos under them. I grabbed my goggles and started walking to the pool.

By the time I walked the fifty meters from change rooms to the edge of the pool, I was ninety perfect erect! Just the feeling of wearing nothing but speedos, the feeling of being out in the open wearing very little is such a turn on for me. I didn’t waste anytime getting the water and as soon as I started swimming my cock calmed down a little bit.

The Married Guy (you’ll have to read my blog to find out how we became fuck buddies) grabbed the lane next to me. After swimming for nearly an hour the Married Guy and I walked back to the change rooms, he had a towel around his waist, I had nothing but my speedos and my growing cock. I’m not sure this erection counts as spontaneous as I knew exactly what we were about to get up to in the change rooms.

The Married Guy and I hadn’t fooled around in a while and he had told me before that he was super horny.

When we entered the change rooms, I headed straight towards the disabled shower, it is bigger than the usual ones and is at the end of the row. The Married Guy checked that there was nobody else in there, threw his towel on his bag and headed down to join me. I had the water on when he came in wearing a classic black speedo.

As I mentioned earlier, I had gotten horny just walking up from the pool, as I got a view of the Married Guy without his towel i noticed that his black speedo wasn’t going to hide his erect cock.

He grabbed me by the throat and pushed me back against the tiled wall of the public shower.

Then his tongue was in my mouth, kissing me hard, there was a hint of violence but it was one hundred percent pure pent up sexual frustration. The Married Guy usually isn’t into much kissing but we were sucking face and our cocks were grinding against each other.

Breaking off our kiss, he dropped to his knees and ripped my speedos down to the ground, the drawstring was still done up but he just ripped them down.
