A fitness enthusiast introduces his friend to a man with a large penis who was previously shy about it

Our story begins in the gym with our protagonist, a fitness enthusiast who loves to show off his muscles and get attention. He's so into fitness that he even walks around the gym without any clothes on, just his athletic shorts. His friend, who's more of a shy guy, is into fitness as well but not as much as our protagonist. One day, he decides to take his friend to meet another guy, a guy who's into fitness too but takes it to a whole new level. This guy is so into fitness that he has a huge dick, and he's not shy about it. He loves to show it off, especially in the gym where he works out. Our protagonist is impressed by this guy's big dick and loves to play with it. He even takes it in his mouth. The black guy is into ass worshiping and loves to fuck. He fucks our protagonist's friend hard and deep, making him moan with pleasure.
