This curse file will take effect when you sit in the presence of other people. You will gradually start squirming, then realize you have a small buttplug in you. The buttplug will take up more and more of your attention as it seems to grow and pulse. In order to attenuate the effect and regain your poise, you realize you have to sit with your legs crossed like a woman, or slowly move your hips in a sexy way. Also, when you stand up, it's like the plug is attached to the chair, so it may make you cry out if you stand too quickly. The sensations are likely to give you an erection. Sitting on a toilet will not trigger this file.
