I do a lot of white water rafting and have gone down most of the major rivers in the western United States including taking groups down the Grand Canyon. One time I was taking a group through Catarac Canyon, a series of 3 huge rapids right above Lake Powell. We put in at Moab Utah. The first part of the river is very flat, and it takes a couple of days to get to the big rapids. I shared a tent with a friend of mine. The first night I went to sleep in just my boxers. it was during the summer and still pretty warm out. I woke up a couple of hours later with my friend sucking my dick off. He evidently had taken my dick out of my boxers and got me hard and started sucking me off. I ask him what he thinks he is doing. He said nothing, just kept sucking me off. So I decide WTF. and just let him suck me off. I shot a huge load and he sucked up every drop of cum, licked my dick off and tucked me back in my boxers. The next night I was almost asleep and I feel his hand on my dick. I knew what he was up to. He ended up sucking me off every night of the trip. By the time the trip was finishing I was shoving his head further down my dick trying to get him to take it down his throat. He would gag, but try to take it all. After that trip he would sometimes come over to my place and ask if he could suck me off again. He said he loved sucking big dicks and couldnt get enough of mine. This all happened when I was still in denial about being gay, and was trying so hard to be straight.
