Resisting the incredible urge to push, he squeezed his butthole as tight as he could. He could feel his P.E. shorts tight around his full, firm ass, as if they were gripping it.
He was an adorable boy. Fifteen, and in Year 10 at school. Smooth, dark brown hair, short but with a long fringe swept to the side. His skin was pale and clear, and his eyes were green with brown speckles, 'like stained glass windows' he has been told.
It was most likely jealousy of his young, feminine looks, but he was bullied at school. The bullying he endured was rarely sexual, but when the higher education students got called in to teach his class's P.E. lesson, his ass was always used somehow. Often, a simple fucking would do the higher boys, but there were a few who liked to act out their dirtiest ideas.
He winced as he pushed his ass on his heels, his knees pressed hard on the tiled bathroom floor. As he spread his knees apart, with his heels pulling on his asscheeks, he tried his very hardest not to let his asshole loosen.
Today, the prefect in charge of his lesson had squirted a tube of lubricant up his ass, and then pushed a thick, fat Perspex dildo all the way up, so that the little hole closed it inside. He was only allowed to push it out after the 45-minute lesson was over and he was back in the changing room with the prefect. Fortunately for him, the lesson had been called short because of a fire-drill, and he had managed to break away from all the commotion and run off to the bathroom.
He hooked his thumbs underneath the tight material of his shorts and rolled them down his thighs. They clung just above the arches of his knees in a rolled bunch, and now without the restricting material, he could spread his knees out further. He put his hands between his thighs and rested the palms on the cold tiled floor, wincing as his spread-legs stretched his wet butthole open. He pushed gently, and gasped as he felt his butthole involuntarily squeezing out wet bubbles, hearing the soft popping noises as they pushed out of the tiny hole. "Ooh!" he sighed, as any pressure released from his bottom felt good.
Saying that, he was desperate to shit the fat dildo out of his butt. He moved his hands behind him and with each one, grabbed an asscheek and pulled them apart, blushing as louder, wetter-sounding bubbles farted out of his weeping butthole. He pushed harder, as if he were pushing a hard shit out, groaning quietly as he felt something thick, and fat stretch his hole open. He felt liquids making the hole feel slippery, but the heavy glass dildo was moving very slowly.
He looked behind his shoulder to the mirror on the wall. He saw his hands pulling his buttcrack apart, and a little of the fat Perspex poking out. He was surprised b the size of it, it felt much bigger as he was shitting it out. He lowered his head and raised his ass so that he could look under his body and at the mirror. He kept his eyes fixed on the reflection of his asshole, and pushed harder. He felt his cock growing stiff, he never imagined seeing something like this would be so hot. He saw the cylindrical dildo sliding out of his butthole, and with one extra hard push, loud, sloppy, bubble-popping farts erupted from his tingling butt, and the dildo burst out of his ass with a 'pop'. He was desperate to feel more, so he continued to push his butt. Squirt after squirt of thick, hot lubricant shot out of the gaping butthole, and more bubbles burst from his ass.
"I.. I'm sure there's more in there, I can feel it," he gasped to himself, and he continued to push harder and harder, but nothing happened. The rush he was feeling was amazing, he needed something more..
