Molly knew it was pointless to try and get up so she stayed where she was, on the floor, legs splayed open, staring at the ceiling.
'Mark, it's your turn.' Without looking, she knew this was the brown haired boy. She heard him moving towards her, then looked as George stepped between them. She heard another condom wrapper open, then heard Mark gasp as George unzipped the boy pants and took his hard cock in his hand. 'You let me do this boy, you'll mess it up.' Then George stepped away and Mark was on her and in her before she could react. This one didn't kiss her, didn't even try to make her come, he just roughly thrust himself in and started pumping away, holding her down, just like he was supposed to. He stared into her eyes as he thrust, grimacing as he came close, and then carrying on. She could see he was trying to make himself last. She gasped as he moved in her, moaning and trying so hard not to come, she didn't want to come with her br...with him inside of her. Mark saw this and grinned, suddenly slowing his movements. He was playing the part well.
George has long ago stopped giving direction and was now once again perched on the edge of his desk, watching as Mark pulled out and started doing what Steven had done, pressing his cock into her clit and moving it oh so slowly, rubbing it, rubbing her until she cried out for him to stop, to please stop, don't make her do that again, she didn't want it, didn't like it. They all laughed when she shuddered and came again, twice. Mark kept going and going, somehow, until he grabbed her shoulders and thrust into her hard, then lay on top of her, panting. George laughed and pulled him back, out of her and away.
She stayed on the floor. This was the worst one. George knelt on one knee next to her. 'How you doing cupcake? Learned your lesson yet? You're not going to be playing where you shouldn't now, are you?' Molly closed her eyes and shook her head. George laughed. 'Well I'm not done teaching you. Get up.' When she didn't move , he roughly grabbed her by one arm and yanked her to her feet, pushing a hand between her legs to feel her wetness. 'I can feel that. With one finger he began to rub her clit, then slid it down and inside her, holding her up as she shuddered against him. He went back to his slow rubbing, and laughed again as she came. 'See? You liked it. You wanted it. Tell Da....tell me you liked it, you wanted it, and you'll never leave us again.' Wearily, she did. George smiled and pulled her towards where the last boy was sitting, chair pulled out from the desk.
'We got one more lesson for you, I think, don't we?' Molly closed her eyes. 'Please. Weren't they enough? No more, I don't want...'
George pulled her close and breathed into her ear. 'No. This is happening. So be a good girl for me and maybe you'll get a reward.'
The last boy was sitting in his chair, staring at her. As George moved her closer to him he made no move to get up. 'This is Charlie. Charlie here was a bit reluctant so we're...ha, you're going to help him out. Aren't you girl?' She just nodded, looking at Charlie, who was slowly unbuckling his belt. George let her go and moved towards Charlie, who immediately stopped what he was doing and let George undo his belt, buttons and zipper, and gently pull his pants down to his ankles, and Molly watched as her Professor gently took the boys cock out, rubbing it and whispering something in his ear. Soon Charlie was hard as a rock, and he moaned when George slid the condom on. 'Now, this one is going to be a little different. Molly, I want you to spread your legs, and we know how you know how to do that, and straddle this fine young man.' He turned to her. 'Then fuck him. If you do a good job, I'll let you go.'
She moved towards Charlie slowly and shakily. Her legs and back ached, she was covered in sweat and her own juices, and she stared at the wall behind Charlies head as she placed one leg on either side of him and moved onto his cock, which was the biggest of the three to her surprise, almost too big.
As soon as the tip of him was in her he moaned and thrust upwards, making her cry out and come. He grabbed her hips and whispered in her ear, 'go slow. Move slow, I want you to be slow, I want to be inside you for as long as possible.' Had she even told George about that?
She came again as she began to move up and down on him, and he groaned and bucked his hips and pushed his face into her chest, sucking her nipples as she moved. She could see the other boys in the background, jerking off.
George must still be perched on his desk. Charlie suddenly gasped out 'Stop. Get off me.' She shakily stood and almost fell as he stood and shoved her into the wall behind Georges desk. Shakily he lifted her, spread and pinned against the wall, and then he was inside her again, this time thrusting hard and fast, face pressed into her shoulder, grunting and gasping. She stared at the other two, who stared right back at her.
Charlie lasted the longest, almost twenty minutes by the clock on the wall, before he shouted and came, letting her fall to the floor, smacking her head on the way down. As she lay there she watched George talk briefly to the three boys who'd had her, heard 'good job.' Then he unlocked the door, let them out, and re-locked it.
