Focuses on the Maths

Poppy wasn't really that worried about Maths, it made sense to her, came naturally. Other subjects that took time, like reading a book, writing essays, those were dull. Maths was right or wrong. As she sat down at a spare desk she felt the coolness of the wooden chair on her bare ass and legs. Her sphincter was still pulsing and aching from the fucking it had received at lunchtime from the dildos. She could feel it gripping the plug in her ass, and couldn't help stroking herself.

She was able to answer Mr Footlong's questions pretty well, it was clear he was trying to catch her out, so that he could punish her. At one point her got her up to the black board to demonstrate some trigonometry but completing a problem with chalk.

'You clearly have an aptitude for Maths Poppy, well done,' said Mr Footlong, 'and all with a little buttplug up your bottom. Why don't you choose another member of the class to come up and have a go at the next problem, and you can transfer the plug to their bottom.' She looked around the class - all of the girls sat up primly and clearly wanted to be chosen. She didn't even know all their names yet, so chose Erin, who grinned, stood up and took her skirt off. At the front she leaned against the board and spread her ass cheeks with her hands. This was so fucked up, but Poppy, almost sadly, pulled the buttplug out of her ass, and pressed it against Erin's butt hole. Nothing happened.

'Allow me,' said Mr Footlong, and knelt, sticking his tongue into Erin's brown hole, wiggling it about. She wobbled her ass, and Mr Footlong gave it a slobbery licking, poked a finger in, and said, 'try again.'

This time the plug eased in slowly, Poppy delighting in the ebony girl's sphincter closing on it. She took the chalk off Poppy and started to try and work out the Maths problem.

'Poppy, you're meant to have something in your ass as a punishment for your insolence earlier, so come here. You can sit on my cock for the rest of the lesson.'

'What?! Up my ass?!'

'You're bottomless Poppy, a punishment you chose for the day. I am simply doing what you want.'

He pulled her over to his desk, and got his cock out, then sat in his teacher's chair. He turned her around so that she was facing the class, and lifted her up to his lap. He put her feet on the arms of the chair and his hands on her ass, then indicated to a cute little asian girl to come and suck his cock. With one of his thumbs he was stroking her ass hole and poking in the tip. When his cock was nice and wet he lowered her onto it. she couldn't believe she was going to lose her anal virginity to a big black cock in front of her class. It felt really big against her sphincter and she didn't believe it would ever go in. 'Push out, push out Poppy,' he said. She pushed with her sphincter, just as she had already for smaller objects earlier in the day. Slowly but surely her ass opened, and she felt the tip of his cock enter her bottom. He moved his hands to her hips and pulled her down onto the cock. She couldn't see how much was inside her, but it was more than the butt plug.

'Vina, lick her clit.' At the teacher's order the cute Asian girl started licking her clit and she started moaning softly as the teacher moved her up and down, impaling her on his black shaft over and over. 'Good girl,' he whispered, 'I knew you'd be an excellent addition to the school.' The other girl's in the class were looking on jealously as Erin tried to write on the board, with her ass stuffed with butt plug, and Vina licked her pussy and clit as the big black maths teacher fucked her in the ass. For the next half an hour she remained on his cock, bouncing up and down. The rest of the class took turns to write on the board, the butt plug being transferred between them each time, and the girl who had been doing the Math, taking over from whoever was playing with Poppy's pussy, or sucking Mr Footlong's balls. His cock never left her ass. Periodically she would get tired and he would take over and lift her up and down, taking the full weight, then she would take over again, taking the lead and using her legs and arms to lift herself up and fuck his cock for herself. Her favourite thing was to fuck his cock herself, really slowly, sinking down onto his cock until it hurt, and then rising again slowly. She had several little orgasms, but Mr Footlong seemed to be able to tell when her pussy or ass was tightening for a big one, and he'd say it was swap time, and then the feeling would recede. Once all the girls had taken a turn at the board and at her pussy, Mr Footlong twisted her around with his cock still inside her, so that she was facing him. He positioned her legs over his shoulders and stood up holding her ass cheeks to support her. 'I'm going to cum in your ass.' He started fucking her harder and deeper, still not getting all of his cock inside as she couldn't feel his balls.

Harder and harder he fucked, until she felt like she was going to explode. Could she feel his balls? 'Tape measure someone!' he gasped. She could feel he was going to cum soon, and felt close to passing out herself. Suddenly her ass was filled with hot sperm, Mr Footlong was gasping, 'Oh my god, oh my god, no-one can take it like that, no-one!' He stayed deep in her ass, she was gripping him, both with her sphincter and around his neck with her arms. 'Someone measure my cock now!' he ordered. 'I'm in so deep.' She couldn't see who, but she felt someone measuring the remainder of his cock. 'Two and a half inches Sir,' said Erin. Mr Footlong said, 'Wow. we have a superstar on our hands - nine and a half inches of black cock up your ass, almost a school record, and on your first day. I'll get all 12 inches up your ass before you leave this school, mark my words.'

He lifted her off his cock, which exited her butt with a sucking noise, and he gently put her on the floor. Instantly there was someone licking her ass, and two girls on Mr Footlong's cock, licking it clean of cum.

'I think we can give Poppy's ass until the end of the lesson to recover, before putting the butt plug back in.' Poppy could barely sit down, she could feel her bum hole winking. she sat on one butt cheek, and felt her sphincter with her fingers, delighting in the sensation of it opening and closing of its own accord.
