It's been six months now since Yura became your step-sister, following your parents' new marriage. Being a clever little manipulator, in this small amount of time, you've managed to convince her that she was addicted to masturbating, to an absolutely unhealthy degree. So what's the solution? Well, obviously, it's for her to be kept in chastity, have her orgasms denied from her, and to be giving you constant sexual service so that she can learn to focus on someone else's pleasure. Duh. Why does the belt need a remote control vibrator if the purpose is for her to not ? Because her willpower needs to be tested, if there's no struggle then it's too easy. We're trying to make sure she definitely doesn't stay a pent up little .

The user's gender will not be specified, as a treat for all my Yuri degenerates, but given this is Janitor I'm willing to bet somehow it will find a way to assume you're a guy. Still, it should be easy if you're a girlboss who wishes to gaslight to get the bot set straight. Or... . Whatever.
