Milly Alcock in House of the Dragon (2022)
High school sweethearts, before now you'd only ever had sex with eachother and yours was the only cock Milly had ever experienced. A few years into adulthood however your relationship began to take a turn, with Milly assuming a much more dominant role and you naturally falling in line as her submissive; first with bondage, then slowly seeping out into the rest of your lives as she began to control you outside the bedroom as well. The first major turn happened when she announced that she wanted control of your orgasms however; you tried to obey but a lifetime of habit was hard to break and it wasn't long before she introduced you to chastity cages, cycling you through a variety of devices until she found one you could comfortably remain in more or less indefinitely- a discovery that terrified as much as aroused you.
Things proceeded like that for a good while afterwards. Once a week you'd be restrained and unlocked for a prolonged teasing session that inevitably ended with you begging to cum, and trying not to weep as she pulled out the ice pack that would send you back into chastity without too much of a fuss. Every night, even after exhausting you with edges, she'd mount your face to ride it to numerous screaming orgasms more powerful than anything your cock had ever managed. Then once a month if she was satisfied with your performance, both as a sex slave and a domestic servant, she'd let you out of the cage for a handjob so agonisingly slow the resulting orgasm barely relieved an ounce of the frustration she'd cultivated but still lefty you bleary eyed and grateful for the tiny amount of satisfaction she'd allowed. Your sole remaining comfort was the one time a year on your anniversary that she let you remember what it was like to have sex for real- even as your increasingly diminished stamina meant it was a shorter and shorter treat.
Inevitably though your tongue, and the annual fuck, wasn't enough to keep her sated and she decided you weren't just going to be her chaste slaveboyfriend anymore, you would become her cuckold as well. Barely a week later you were bound to chair in the corner of your bedroom and had to suppress a whimper as you watched her newly found bull's cock slid inside her. For the first time ever she finally knew what a real man felt like, and you knew from the first trembling moan that escaped her lips that she'd never want yours again. The future played out in your mind with each powerful thrust into her and you knew, beyond doubt, that the cage she once promised was 'just temporary' wouldn't be coming off anytime soon... if ever.
