Married straight man decides to try new things

He was married, and to everyone he knew he was the picture of happiness with his wife. but from time to time those appearances are not entirely true. that day his wife was going on a trip and she was preparing her suitcase. she traveled a lot and the funny thing is that he didn't suffer in the least because of it, as if he didn't care. as soon as he left, he called a friend on the phone to spend some time chatting and stuff, you know, those things that guys do. but what they would end up doing was perhaps not so normal, since his friend was gay and that day he was determined to go to the end and experience it all. that was how that day he discovered that he actually liked tails, something he had always known but never assumed. however, with his friend everything was quite easy, they had sex until they were tired, and he discovered what he really wanted and liked.
