In my senior year of high school, I worked out every day in the HS weight room with two buddies, Thomas and John. We were all pretty horny, and they liked seeing my big bulge in my shiny Nike sprinter shorts and my satin boxing trunks. We started jacking off just like this. One day the student teacher assistant coach, a handsome bearded guy just a couple of years older than us from the university, walked by and noticed that I was tenting my running shorts. He stood and looked at me for a while without a word. Then he walked down toward the men's room, and turned to look back at me. I gave it a couple of minutes and then followed him when the other guys were distracted lifting. He was standing in one of the stalls with the door open, and he said "Hey stud, how's it going? I want to check out those shorts, so come on in. I didn't know what he wanted but was horned up, and he was pretty damn sexy in his coach shorts and tank top, so I went in. He sat on the john and I stood in front of him with my bulge at his eye level. He stared at it for a second and then reached his hand up to feel my shiny shorts. "These are nice... I need to get a pair." He moved his hand up til it brushed against my stiff tent, and then he closed his fingers around the head and started rubbing me. It felt incredible. Then he started licking my rod and head through the thin nylon, making little moans as he did it and making me moan as well. After a while he took hold of my big cock and pulled it out the leg of the shorts. The stared at it with a big grin on his face, and then he started kissing the tip and licking around my head gently with his tongue. He looked up at me and whispered,"You're a stud.That's the biggest dick I've ever seen, stud."He licked his lips and then started to go to town on me. We were both moaning but trying to keep it quiet, but John and Thomas had gotten curious about what we were up to, and I heard them come into the room. Coach didn't stop, and his sucking sounds and moans were getting a little louder. I decided to open the stall door so my buds could see what was going on, and I moved to the side so the could get a full view of coach servicing my huge cock...
