My name is Jason. I was 17 at the time of this story and had some pretty tough classes going through high school. My favorite subjects were all math and science based. I had one teacher, Mr. Rogers, he was both my math and physics teacher.
I had known I was bi for quite some time and I had the biggest crush on him. He was about 40 and I had a huge attraction to middle aged guys. He had brownish gray hair and short too. He looked about 6'2" or 3 and had quite a nice body. He was a runner and climber and I would see him at the gym working out. He sure was buff from the looks of it and he had a layer of hair covering his whole body. I myself was about 6 foot and had brown hair, but I was hairless besides my cock and butt. I was also a runner and skier and was in pretty good shape.
Whenever I watched porn I looked up pictures of middle aged guys like him and whenever I came I would moan his name and imagine his sweet juicy cock penetrating my anus as I fingered myself. I sometimes would fantasize in class and imagine what it looked like and how big it was. I also tried to look at his crotch and watch for his bulge. When I looked it seemed it was sticking out by some bit. Although I had never had sex before, I craved his dick in my hands, in my ass, in my mouth, I didn't care where, I just needed to see it and touch it.
One day I had to stay after school to get help for my physics midterm. We reviewed the material for 30 or 40 minutes then we started to talk about sports and my plans for this year. We started to laugh and tell jokes. We got into an awkward area about girls and our love lives. He said that he broke up with his girlfriend last month and I replied by comforting him. I asked him if she at least was worth nailing. Surprisingly he responded and said she gave a wonderful blowjob. This turned me on, talking about his love life, I started to get a semi hard-on.
He was standing at that moment and I could see a change in his pants. HE HAD A BIG FAT BONER! He quickly sat down at his desk and tried to ignore the fact. He said he had to get some work done, and I left. I could still picture the gigantic bulge in his pants and I quickly moved to the nearest bathroom to relieve myself. I entered a stall and dropped my pants. I had already gained a full hard-on. I started to massage my cock and was near my cum when the door opened. I could see though the cracks of the stall Mr. Rogers.
He took his teacher key and locked the bathroom, not bothering to check the last stall. Suddenly he started to strip down and he was only in his tight briefs. The same bulge remained and he then walked back to the door and grabbed a small bag. He zipped it open and removed what appeared to be a bottle. "Lube?" I thought to myself. He then removed a massive dildo that appeared to have veins in it. He opened the bottle and poured some on the dildo. He finally removed his briefs.
I almost fell over, his cock was MASSIVE, it must have been 9 inches. He leaned against a wall and started to rub his cock slowly. This drove me nuts and I almost came. I took a look at his body as he pleasured himself. Very tightly on the head, freshly shaven and clean, as my mesmerized eyes moved down, he had a small layer of hair covering his pecs and his nipples looked oh so fine.
As I moved down again he had a very defined 8 pack and a loose layer of hair, not as thick as on his pecks. Finally there was a giant gray bush that sat atop his massive cock. And it wrapped itself around and down into his anus.
He started to rub lube onto his cock and move faster. He then set that aside and picked up the dildo. He then leaned over the sink and fiddled with the dildo around his ass crack. He slowly inserted the head of it and moved it in slowly. He had reached half way when he started to moan and I started to pleasure myself. I instantly came and force of habit made me moan, "Fuck yeah, Mr. Rogers!"
He jumped up and then saw the form and shoes in the stall. He panicked and covered his cock. I just showed myself, I thought! What should I do? Without thinking anymore I opened the stall and said, "Need some help with that hard-on?" My pants were around my ankles and a fresh cum stain was on the floor.
He looked at me and said, "Well, why the hell not?"
He removed the dildo from his ass then pulled me out of the stall.
