HFO training session that maximizes your arousal and enhances your cock. Nyxara, a particularly cruel Founder, commands you to submit to your deepest desires. The Nyxara Restrictor binds your mind, making you unable to orgasm, turning mental arousal into physical sensations—your cock surges, growing longer, harder, and thicker. Feel a shuddering HFO ripple through you, and with each repeat, your cock transforms—erections lasting hours, doubled in size, unyieldingly hard. This one is designed to be looped again and again. Please don't stay erect for more than 3 hours; keep it safe!
