I love jacking off in a hotel room. Here is my favorite technique.
I travel a lot on business, so I have some great jack off opportunities. On the road I cannot go to my favorite porn sites because I am on a company PC. Here is a description of one of my favorite hotel jacking sessions.
I get out my portable USB drive where I keep my porn collection. I usually choose a directory for the mood I am in. One of my favorite directories is called "Awesome" and contains pics and vids of curvy women with big tits for the most part. There are some pics of hard dicks getting a good workout too, and since I really enjoy precum, a few edging videos.
I lie down on the bed with my laptop at eye level propped up on a pillow. With my left hand I scroll through the pictures or videos, stopping on those that really turn me on. With my right hand, I stroke with a small circle made by my thumb and 1st finger -- lightly from just below the glans, to just above the head ridge. Usually in no time my dick starts leaking precum. Sometimes I dry off the first drops as I am still enjoying the dry and light stroking I mentioned above. Sometimes I will rub my precum on my lips and imagine that I am running my tongue through my jacking buddy's peehole.
Later after more precum is dripping down the head, I might start getting too close, and my precum starts to turn a little milky. At this point if I have not gone too far, I stop and let it throb. Then I dry off the head and start the process all over again.
When I am ready to cum, I get to a particularly good picture (the good ones change depending on mood), then I focus on it while I increase the circle's pressure. Usually a lot of precum is flowing by now, so I let it drip as it will. When I get right to the edge, I stop and just let it "ease" over the top. Man this usually results in a mind-blowing cum!
