He sat on his desk, and started teaching us about the area between a prime angle and a double prime angle. I watched as he spoke, Mr. S was so dreamy. He taught at an all boys school, but something about him just...made me feel wild. He kept speaking, when I thought of something crazy. "What if we got him to jerk off in front if the class?" I whispered to my friend. He chuckled. "He would never do that! You know him, he's too much of a-" Mr. S was apparently listening, because he opened his legs a bit. "Has anyøne ever wøndered høw long the average entity penis is?" He asked, and almost instantly, everyone shot their hand up.
He sighed. "Well...I guess I'll shøw you then." He opened his legs a bit more, and unzips his pants. He was huge, it was about 9 inches. I shot my hand up. "Yes, Gary?" He asked, panting slightly. "How big is it when it's erect?" He blushes a bit, and his cock twitched a bit. "W-well, Gary...um...I..." He kept talking, his cock getting harder. Everyone started snickering and giggling. Some took their phones out. "Ø-øh...my..." He blushed deep red. I could tell he was embarrassed, having a hard cock in front of a class of 15 year old boys. He lowered his hand down towards it, it was twitching, almost asking for it. He slowly started rubbing the tip. He panted slowly, teasing around the tip with his fingers. I saw some kids taping it, other kids blushing wildly, and me...I just watched. He started to slowly rub the shaft, slightly panting more. His face was entirely red, all the kids had their phones out now, except me. I just sat there, silently watching, redness across my nose. He hung his head back and moaned, he sounded so fucking hot. I could see a bit of pre-cum drip onto the floor. Before I knew it, he was on the verge of climax. He moaned louder and louder. "I'm cumming!" Cum shot at us, covering me in his silky white seed. He panted. It was a fun day.
