[M]y first time trying to suck myself.

It was yesterday, 7 days without an orgasm. I just needed to know if I could reach my mouth with my penis. Even though I’m not gay and I never want any other penis in my mouth, I just needed to know if it would work.
So I layed back, put my legs behind my head as I wanted to do a roll backwards. At first my penis hang over my nose, but after moving a little I could finally reach it with my tongue.
At this point I knew I could do it. I relaxed more and then it happened. Nearly the whole glans of my penis was in my mouth. After some more experience with the position I slowly started sucking my own penis. I couldn’t believe that it worked so well in the first try.
I didn’t wanted to go any further, I only wanted to make a quick picture for myself. So my penis went back in my mouth, I took my phone, made the picture.
But then it happened. Without any warning I orgasmed with the whole glans of my penis in my mouth.
At the first I thought I could stop the orgasm, so I stopped sucking. But then I felt the first warm drops of sperm on my tongue. I kinda paniced and swallowed. Knowing that I couldn’t stop now, I started sucking a little. And a fucking huge load of sperm from seven days ended in my mouth. It was warm and tasted kinda strange but then I swallowed once more and it was all gone.
Wow, at first I only wanted to test if I could reach my mouth but in the end I ended up sucking and swallowing a huge load of my own cum.
That was a strange experience.
