Nick had been watching Luna for a since the start of the school year. She had started in his class at the beginning of the year as a new teaching assistant to the school. Whilst she was always polite, professional and intelligent, something about her made him sure that she was a filthy slut as well. Little things about the way she acted or laughed at some things in the staff room. The smile she got when she thought no-one was looking - a secretive I know more than you think sort of smile. He'd started to do some research and through his numerous contacts around the county found out she was on a website dedicated to kink and fetish sex. Some of her photos were particularly predicative although unless you knew what you were looking for you would never have recognised her.
He'd struck up a friendship with her, professional and helpful but having a laugh as well, all the while compiling information and photos and planning for the time when he would make his move. With an anonymous account on the same site he'd discussed fantasies and what turned her on - she claimed to be a pain slut and needed to be hurt during sex as she enjoyed it more. She had darker fantasies about teasing someone until they forced her to be their slutty fucktoy. This only solidified his plans for her and he started to plot how and when it would happen
The day after that particular revelation he'd struggled to hide his hard cock from her all day as she'd been wearing a skirt and top that accented her large breasts - he was almost sure he could see the piercings through the material. She was short, just over five foot which was his preferred victim type, dark haired and by now he had enough dirt on her to destroy her if he so chose. He had been waiting for the best opportunity and that provided itself when he organised the staffing for the school residential into the middle of the Lake District. He'd been many times and knew the layout of the hotel - allocating the two most resort rooms to him and Luna.
In the run up to the residential Nick planned a variety of things to prep his slut-to-be for her future as his fucktoy. He upped the game on the kink website sending more and more filth to her - daring her to do things like going to work with no panties on. Nick has really enjoyed that - she had walked round all day and he could tell how horny she was with no panties on - it took all his control not to do something that day. She confided more and more a put her fantasies about being forced and used and hurt. Finally the day of the residential came and they set off on the bus. He sat next to her and chatted normally the whole journey while on his heat he was planning what he would do with her that night.
As always the first day was jam packed full of activities and the kids settled down for the night without a fuss - not always the case but Nick had arranged which staff would deal with problems on each night. Once the kids were settled the staff went and freshened up before heading to the bar. Luna joined him and a couple of other staff in the centre bar for a drink, she was wearing summer dress that flowed around her curves given the warmth of the evening. Nick was sure she wasn't wearing panties underneath as that had been one of the dares from her 'online friend' before she went away. They sat laughing and as it got later and the other left he bought Luna another archers and lemonade but made it a double. She wasn't wasted but she was certainly a little bit drunk. Eventually it was late enough for his plans. They finished up and headed towards their rooms which were next to each other at the back of the centre. Normally Nick used the for the pupils he knew would cause trouble on a night because they were isolated - tonight he would be the one causing Luna some trouble.
As they reached his room he unlocked the door and pulled her inside before she realised what was happening. In her alcohol fuzzed mind she turned laughing to ask what he was doing. The bag he'd left beside the door had everything ready. Grabbing her arms he spun her to slam her against the wall knocking the breath out of her. The cuffs slipped easily over her wrists fastening them behind her back. As she opened her mouth the shout or scream he forced the gag into it and fastened it behind her head as she helplessly tried to escape his grasp. Dragging her across the room he threw her into the bed and then opening an envelope dumped a pile of photos over her head on the bed. She looked at him and then them in shock - still trying to process everything. The photos were of her, in various states of undress, or masturbating in some cases. Some were screen shots of her fantasies and the filthy things she had told her online friend.
"All the e-safety we taught at school this year whore and you didn't pay attention. Careful what you post online. It may come back to haunt you."
He knelt on the bed beside her and grabbed the light summer dress tearing it into pieces and stripping it off her as she sobbed into the covers. Under it she only had her bra on - which he left for now. He slammed his hand down onto her ass loving the crimson hand print that immediately blossomed on the pale soft skin. Repeating this on the other cheek he then stood and took a photo of the clean hand prints on her ass.
"Your body belongs to me you filthy little cumslut. Master owns you from the top of your head to the tips of your toes and everything in between. By the time this week is through you will accept that and it will make you happy. The sooner you accept that the better this will be for you."
