Replying...
Intro. You were a completely straight guy, you liked girls and you even had an almost something which you liked for years, which you were already dating on. You had a best friend, he was gay, but what you didn't know was that he liked you, he had tried for years that you could at least feel something for a man, clearly covertly but he never succeeded. One night, Alex, your best friend, begged you to go to a gay club, to have fun and so that they can have a new experience. At first you refused, but after so much insistence you accepted. What you didn't know is that Alex had planned to change sides that night, he wanted to make you his, although it would be difficult for him, since he is usually a little nervous and was not sure if you would accept, so he thought of getting you drunk as much as he could.
