"Seduction" by A Magician (a-magician@mailcity.com). Because of a failed marriage, the narrator has become seriously depressed. Seeing little meaning in life, he finds himself poverty-stricken and practically homeless on Christmas eve in Atlanta. Because the YMCA where he is staying is crowded, he is assigned a roommate - a handsome young man who comes on to him and eventually seduces him.
It turns out to be one heckuva sexually intimate one-time encounter. The narrator does not "become" gay, but he thoroughly enjoys the experience, and it rejuvenates his life. The author does an excellent job of vividly integrating past memories with current sexual experiences.
If this involved women, I would label it "hot ff sex," and readers of both genders would enjoy it. However, I suspect that since this is "hot mm sex," some men will not enjoy this story. I personally did enjoy it very much, and I urge you to take a look at it with an open mind.
