Last part
Sir untied her arms from above her head but only momentarily as he turned her to face the window. Her arms were pulled up and out to the side and held there while she felt something attached to the cuffs. Then her arms were pulled higher and she felt a metal bar against her hand. Sir had attached a spreader bar to hold her arms in place. He repeated the procedure with another, wider spreader bar between her arms so she was spreadeagled and held tight. Sir told her to open her mouth and she felt the cold steel of the spider gag holding her mouth wide open. Sir knew she hated the spider gag. Again her reached round her and pinched her nipples hard before rubbing them between his thumb and forefinger. A sharp nip meant the return of the nipple clamps but these felt stronger than before and she gasped with shock. But they weren't just nipple clamps; she could feel a chain hanging down her towards her stomach. There was a tug on the chain which made her wince before Sir moved his hands between her legs, again using his thumb and forefinger to rub either side of her clit. But this wasn't to turn her on, he was locating either side of her clit so he could apply the final clamp to her most sensitive spot. She drew in a breath sharply as Sir started tugging on the chain, pulling her nipples and clit at the same time. She tried to close her legs but had no chance of that as hands moved onto her arse and started spanking her hard. "Did you think you'd escape punishment for coming without permission" Sir asked her. She tried to mouth the words "No Sir" but with the spider gag holding her mouth open, only unintelligible noise came out. She shook her head instead to signal that she understood why she was being punished. "That's good" Sir said "because your punishment isn't over yet. Do you understand?" She nodded her head slowly as the spanking continued.
She heard buzzing and knew Sir was going to put the vibe onto her clamped clit, the clamp making it so much more sensitive than it already was. But before he did that, he told her to lean forward so that her forehead was touching the glass. This tipped her off balance but she shuffled her feet forward to take the weight and pressure off her arms. Then Sir reached up to her head and untied the blindfold which had been covering her eyes the whole time. "Now don't move" Sir told her. The angle of her head meant that she couldn't see back into the room but she could see out. Sir whispered in her ear "Now you can see what a good little slut you are, tied up against the window so everyone can see you exposed, your tits and your pussy clamped for me to use as I want to" She really didn't want to open her eyes. Until now she had been in her own world and she wasn't sure she wanted to see reality. But Sir told her to open her eyes and look down onto the street while she was being restrained and spanked. Then the buzzing stopped being a sound and became a sensation, the deep, slow vibrations transferred directly onto the tip of her clit. There was no escaping from it and she was already drooling onto the glass from her forced open mouth.
Sir gradually increased the speed on the vibe as her legs began to shake. A hand reached from behind her reached between her thighs and rough fingers found her pussy, finger fucking her quickly as Sir continued his onslaught with the vibe. "Now this time little slut, I want you to come. I want to see you come in front of everyone in this room and anyone outside who can see you in this window" She turned her head to beg with her eyes but he just turned her head back onto the glass so she had her face to the world. Sir was watching her very closely and as soon as he saw she was about to come he removed the vibe. "Aren't you going to come for me like a good little slut". She nodded quickly and he put the vibe back, turning it up as she moaned through the gag. He let her get close again, then stopped the vibe "I thought you wanted to come" Sir asked her, knowing he was torturing her by his actions. Finally, he turned the vibe up to full speed, pulled the clit clamp forward with one hand and pressed the vibe directly onto the exposed tip. She was almost screaming behind the gag as she was finally allowed to come, her legs turning to jelly as she convulsed against the restraints and the hands on her body. "What a good little slut" Sir told her, "I'm sure your audience outside really enjoyed that performance".
Sir released her from the bars and put her blindfold back on before telling her to get on all fours on the floor by the window. Quickly a cock entered her from behind and the man pulled her head back by her ponytail. Her mouth was already held open with the gag and another cock took the opportunity to totally fill her mouth, holding her head to force his cock deeper into her mouth. Sir started talking and she realised that his wasn't one of the cocks. "I want to see you really fucking those two cocks" he told her "they're going to keep still while you do all the work now". She knew what he wanted to do. She opened her knees further and started pushing back onto the cock. "Harder" Sir told her. The man in front of her moved position slightly so now when she pushed back, one cock was deep in her pussy and when she rocked forward, the other was deep in her mouth. "Fuck them harder" Sir told her again as he reached underneath her to pull on the chain still holding all the clamps in place. She forced her hips back as hard as she could as the man behind her grabbed her hips at the same time, forcing his cock in as deep as it would go. He was pounding her pussy so hard until she felt him stiffen, , holding her hard against him as she felt his warm cum started dribbling down out of her pussy.
As soon as he withdrew, she felt the woman sliding in underneath her, quickly guiding what must have been a strap-on into her dripping pussy. The dildo was bigger than the man who'd just been fucking her and she gasped at its full length as the woman pulled her hips down onto it. Sir moved behind her and pulled her knees further apart and her arse higher up. She felt the pressure of his cock against her arse as her muscle stretched to accommodate it. He slid in slowly at first but quickly picked up his speed, matching his thrusts to the strap-on that was fucking her from underneath. She had never felt pressure like it, or felt so full as she was now, but she quickly stretched to accommodate both of them as Sir began fucking her arse harder, grabbing her hips to allow him to thrust deeper into her. "Fuck that feels good" he said "how does it feel that all your holes filled, my good little slut" although he knew she couldn't answer, she still had a mouthful of cock. He was fucking her harder and harder as the dildo was buried deep in her pussy, two pairs of hands holding her body still so they could thrust harder. "Such a good little slut" Sir murmured again and she knew Sir was be pleased with her taking everything he'd asked her to do.
The man fucking her face was making her gag so much she could barely breathe. Sir loved the sound of her gagging and was telling her to keep taking that cock in her mouth, so she gasped between thrusts as the cock hit the back of her throat. "As you're being such a good little slut" Sir told her "I want to see if you can be be a good little cumslut as well. You've already got cum dripping out of your pussy, I want to see it running out of your mouth and down your face when he's finished with you sucking his cock". She knew she didn't have any choice in that - the spider gag was holding her mouth wide open as the cock fucked her face harder and the metal of the gag dug into her mouth and lips. But all three were still fucking her hard and she didn't know who would cum first - Sir in her arse or the stranger in her face.
Sir slowed his thrusts slightly and she knew he was trying to hold back because he wanted to see the stranger cum in her face before he was done. The cock fucking her face held her head even harder and was frantically thrusting into her mouth. Sir pulled her ponytail back harder so he could get a better view of her face as the stranger first sprayed her mouth with his sticky cum before pulling back and emptying the rest of his load onto her face.
Sir was riding her arse so hard now, gripping her hips with one hand and slapping her arse with the other. "Don't swallow it" Sir told her, but she couldn't even if she wanted to, she couldn't close her mouth and so the sticky liquid just ran slowly out of her mouth and down her chin. Then she felt Sir groan, and force himself in as hard as he could, holding her there as he too came, deep inside her arse. As he pulled out, he stroked her arse and back gently before pulling her off the dildo still in her pussy. "I don't think we're quite finished yet" Sir told as he moved her around. He reached behind her head to remove the gag, still dripping in cum. "As you've been a good little slut for me, I want you to lick that dildo clean, get all the cum off it and into your mouth". He guided her head towards the dildo, and she did as she was told, licking from the base to the tip, tasting herself and the stranger who'd cum inside her.
Once she'd finished, Sir got hold of the leash and pulled her to her feet, her legs still wobbling. "And finally, I think I'll take you for that walk again" Sir told her "see if there's anyone in the corridor who'd like to see a good little slut and how pretty she looks with cum all over her face and dripping down her legs"
