Gary had always been close with his father. Since he was little, they'd done everything together, from going to the movies to eating at the restaurant. The two had never strayed apart, they'd always been getting closer and closer together, until finally Gary and his father realized they were in total love with each other, not just loving each other. Gary was 19 when they first realized it. His mother was out of the house for the day, and Gary was lounging around, reading a novel. It was his week off from college, and he was reading an erotic fantasy, when he decided to ask his dad if he wanted to do something.
His father was at the computer, so Gary walked to the door and opened it, and looked at his father, who was sitting in the leather chair on a fake cock, and staring at porn as he jacked off furiously. Gary stopped in his tracks, and stared at his fathers 6 inches. It was covered in pre-cum, and he continued to stroke it as he turned to look at Gary, who's penis was so turned on by his father, sitting there naked, that it bulged heavily out of his pants.
His father quickly covered his cock, and exited the site fast. "Gary . . . I . . . uh . ." was all he got out, before he realized his son's own cock was semi-erect just from looking at him. Gary just stood there for a bit, until finally he spoke.
"Dad . . . I . . . I don't know what to say. I'm really turned on by you! I'm sorry for walking in on you."
His father just smiled. "It's okay, son. I guess you know your fathers little secret, and I know yours," he said, motioning to the concealed dick inside Gary's pants. He looked down and saw it, and looked up again.
"Would you like to see it, dad?"
His father smiled. "I think it's time we got a little closer. From now on, you shall refer to me as 'master'. If you want me to look at it, you shall do as I say."
Gary looked at his fathers cock, and realized he had to have it, and smiled. "As you say, master. Kinky! I like it."
Gary got off the fake one, and moved to the corner of the room. "Your mother and me sometimes play master and slave. You, Gary, are now my slave. Bow to me, slave!" Gary got down on his knee's, and bowed to his father, as he took out a bunch of leather and clamps, and brought them to his son, throwing them down next to him.
"Now, slave," he said, as he threw his shirt off to be totally naked, "Suck me. Take me inside of your mouth!"
Gary looked up at the cock and, slowly, took it in his mouth, moving delicately down the shaft of his fathers sticky penis. His master leaned down, and, picking up two tit clamps, placed them on his sons nipples. He moaned, but continued to suck his fathers hot cock.
Gary's father, John, grabbed his sons hair, and pushed him further down the shaft, so that he gagged. "Slave! How dare you! You shall not gag when taking me in, for any reason, or punishment shall be given." And with that, he face fucked him, driving the cock down his own sons throat, who not twenty minutes ago he regarded as a close friend, nothing more. Gary sucked at him, twirling his tongue around the cock as it slid down, struggling not to gag.
