Sucking my own cock.
When I was a young teenager, I realized that if I layed on my back, with two pillows under my head, and my legs bent up with my feet pulled up over my head, I was just barely able to get my lips around the head of my cock. It felt amazingly good, as I had never had a blow job or any kind of sex before. After a few weeks of practice, and stretching my back muscles more each time, I was eventually able to get over half of my 7 inch cock into my mouth and give myself a right proper blow job. I especially enjoyed cumming in my own mouth. On one hand, it felt so good to cum in a warm, wet mouth, and on the other hand, it felt so wrong to have a cock cumming in my mouth, although my cum tasted quite good. I am totally not gay, and have never had any desire to suck another mans cock, and have been happily married to my wife for many years, but I really miss sucking my own cock. As I got older, after a back injury, I lost the flexibility I needed to do it. My wife is a very good cocksucker, but I would love to be able to suck myself off again.
Oh the glory years... When I was a kid I use to do the same. I was flexible enough that I could put the head of my cock in my mouth and make myself cum in my mouth. I loved it. Now I'm in my 40's and not so flexible to be able to bend that much. Miss those days..
I thought those years were all behind me until I told my GF about them. She invited me to join her yoga and Pilates classes and six months later she masturbates watching me suck my cock, has gotten into a contest with me for who can deep throat my cock further, and is trying to learn to swallow my cum like I do.
I used to put my cock in my mouth too when I was around 15. I enjoyed it most when I got out of the pool, came inside to change and I sat on the toilet and tried sucking myself. My cock was so warm, smooth and hard, and I got a little bit more in my mouth than usual. If I had more time alone in there, I would've tried putting the whole thing in my mouth and sucked until I came. I mainly just like precum. I hate that I can't do it anymore either.
I'd definitely do it if I had a cock!
