My college biology teacher, Mr. Dexter, was in his early thirties and always dressed in baggy suits that never gave any indication if he had a good physique. He was a handsome man with thick dark hair and brown eyes, and he was also the football coach, with me on the team. On the first football practice of the year, it was unusually warm, and Mr. Dexter entered the field, strutting around wearing a form fitting white t-shirt that showcased his muscles, and what I would call obscenely tight gray shorts that looked polyester or spandex. His thighs were lean muscle and the legs of the shorts were only about one inch long, showing almost the full length of his firm thighs. Then he turned around. The material of the shorts was straining against his round, high, obviously tight ass cheeks, and I could see the lines of a jockstrap beneath the shorts. I wasn't the only one who noticed, as I looked around at the other guys and I could see that their eyes were on his ass, and that they were trying hard to avoid looking, but couldn't help themselves. It proved to me that it doesn't matter if a young man is gay or straight, when he sees a guy with a hot ass, he is going to notice. It could be out of admiration, envy, the goal of achieving an ass the same, or just raging hormones. Mr. Dexter's hamstrings were defined, and as he walked I could see the muscles in his ass clenching and releasing. The shorts were obviously too small for him. Mr. Dexter showed us the proper way to hike the football, bending right over, which caused the back of the too small shorts to creep up. The guys were all looking! When he stood up straight and took a few steps, I saw that the shorts had crept up to expose at least two inches of the bottom portion of his extremely tight ass, with just a hint of a white jockstrap showing, which made things even hotter. I love jockstraps! Several more minutes passed and that ass was eating those shorts. Mr. Dexter either didn't care or didn't notice, as he kept the shorts just as they were. I couldn't even focus on the game, I was so horned up. As he walked around, it was the clenching of his ass that got to me, as I imagined that's how it clenched as he fucked his wife. After football practice ended, we entered the school. Mr. Dexter said that he had to make a quick trip upstairs to his biology classroom, still wearing the shorts. I couldn't help myself, and followed behind him. As he very slowly and deliberately climbed the staircase, I was two steps behind him, damn near salivating at the sight of his round, clenching ass and tapered, arched back. A good two inches of his tight cheeks were showing, with the white jockstrap now clearly showing. As he calmly climbed the stairs, the back of his t-shirt was riding up, exposing the top of the gray shorts, and a V-shaped ass cleft. That sexy ass cleft really got me. I could feel pre-cum leaking out. Down the hall he went, and back down the stairs I went, fully erect. Football practice was was amazing that year, as Mr. Dexter showed up in a variety of tight shorts, ass on display, and becoming masturbatory fantasies for many years.
