Light Binding

Lux tended to her and her brother's quarters dutifully, cleaning each and every corner with precision until the room was near immaculate. As they were siblings, Demacia allotted them a living area with two separate rooms attached. Having already cleaned her room, she decided she would tidy her brother's as well. It had not been the first time she had made this choice, and he was always grateful, so she was rather glad to do it. Rising up the stairs, her heart skipped when she heard noises coming from the room. Her brother was supposed to be out for the day, could it be a thief? Perhaps a Noxian assassin accidentally toppling some of her brother's things as he sought a hiding place?
Barging in without another thought, her wand raised threateningly as she felt her heart sink. On his back was her brother, the Might of Demacia as Katarina, the Sinister Blades jumped up and down on his cock, the girl obviously too interested in their lovemaking to take notice of the girl standing in the doorway.
Lux's heart was racing, everything she had been taught was contradicted here. Sex was for marriage and procreation, Noxus was the enemy, her brother loved her above anything else. All these notions were shattered as she shook in the doorway, her shocked expression settling into an infuriated one as she clenched her teeth her eyes focused on the Noxian intruder and her brother the traitor to Demacia. Putting one foot forward with a loud stomp she broke the spell between Katarina and Garen, their shocked expressions doing nothing to quench the girl's rage. "Lux.." Garen began slowly, ready to beg if it would soothe her, "Luxanna, brother." she replied coldly, whipping her wand out in front of her as light bindings flew out binding together both of their hands and feet, with an extra binding around their necks 'just in case'. Licking her lips as she prepared herself, stripping down to just her royal blue bodysuit, Katarina finally spoke up. "Lux you need to under-" "MY NAME IS LUXANNA, YOU NOXIAN SLUT." she screeched, cutting the girl off as she willed the collar of light tighter around Kat's neck. Satisfied with the silence she relented, releasing the constriction of her windpipe. Gasping for air, Kat had tears in her eyes, laying against Garen in complete silence as she waited for Lux to do as she willed.
A devilish smile stretched across her face as she allowed them the use of their arms and legs again. "Continue." she commanded, her unwavering glare enough for them to cast aside their shame, Katarina mounting Garen's surprisingly stiff shaft, lowering herself onto him slowly before starting to bounce up and down. They soon found, that their shame was heavily outweighed by the exhilarating feeling that was Lux controlling them, regulating them. Whenever she thought they were too fast, she would choke them to slow down, and if they were ever too slow, they could feel a brief shock slide out of their light collar, spurring them to action. Removing them from control completely gave Lux a sense of pleasure too, she could feel the moistness between her legs, her nipples poking out lewdly from within her bodysuit.
It didn't take long for her to include herself, a hole torn into her suit to allow access to her dripping cunt, similar holes also freeing her breasts from their binds. She bounced happilly on her brother's dick, moaning as Kat licked and suckled, teasing each nipple in turn. Luxanna reveled in her control, the light bindings keeping her pets obedient and honest, as they earnestly sought to please her.

Removing her binds after hours of use, there were obvious marks left behind- slightly tanned rings where the light had hugged their skin. Free for the first time in what seemd like forever, Garen and Kat looked to Luxanna blankly. "You can leave, or you can be mine." she said coldly, the ultimatum not living past the first minute as the two quickly sat themselves at her feet, looking up to her dreamily. "Bright decision."
