The wheel (Pixiv Fanbox)

Naughty trainees need punishment. What’s the worst kind of punishment in a dungeon full of pleasure? Correct: Orgasm bans~ You have no idea how frustrating it is to be kept on the edge without release while having to hear the constant moans of other trainees echoing through the dungeon halls. Our newest tool to make sure this experience is as much fun as possible is the wheel. The trainee is tied up with their legs spread open and a wheel with six ultra-fine feathers is placed right in the middle of their crotch. The wheel is connected to a heartbeat sensor, speeding up when the heart slows down and slowing down when the heartbeat increases – thus constantly keeping its victim at the edge of an orgasm. All the trainee feels are the periodic swishes of feathers gently brushing against their most sensitive parts. Nobody so far has been able to endure this form of orgasm-ban without going insane after a very short time~ Let’s see how long she lasts before breaking down!
