Your story of your quickest orgasm ever reminded me of what had to be mine. Probably not 30 seconds, but definitely under a minute. And that going from not erect to cumming, so pretty quick for a guy!
Anyway, I was on a trip taking a class for work, and had a room to myself. After a full day of class I headed to my room to chill before going out to dinner with others from class. I flipped on the TV and sat on the end of the bed. Flipping channels, I came across this show about sex, and they were starting a segment that showed a woman from the shoulders up as she masturbated to orgasm. Holy cow I thought, this is amazing!
The woman on the TV was cute, and her facial expressions kept getting more and more intense. I quickly grew rock hard watching her. To me, there is nothing more beautiful than watching a woman's face as she orgasms.
I could tell she was getting close to cumming, and man did I want to cum at the same time. I ripped my clothes off, dropped to the floor on my knees in front of the TV, grabbed my rock hard penis, and started pumping like mad. She started breathing heavy and then she got that incredible look on her face as her orgasm hit. The sound of her moans sent me over the edge at the same time, as wave after wave of pleasure washed through my body. I stared into her eyes as I came, she felt like one of the most intense lovers I had ever known. And here I didn't even know who she was!
Thanks for sharing your story, it brought back a fond memory.
