Yurin's fingers worked efficiently at the clasps, releasing Seo-yeon's wrists and ankles from the spread bar. The metal clicked open, one restraint at a time, and Seo-yeon felt her limbs slowly returning to her control. Her arms lowered from the position they'd been held in for what felt like hours, her legs finally able to close after being spread wide and exposed.
"Let your body relax," Yurin murmured, her hands gently massaging Seo-yeon's shoulders and thighs, working out the tension that had built up during her restrained state. "Let your muscles unclench."
Seo-yeon followed her guidance, letting herself go limp against Joon-ho's chest. The sudden release of tension triggered something unexpected in her body—her inner muscles relaxed completely, her cervix softening and opening in response to the prolonged stimulation she'd experienced. And then she felt it—Joon-ho's cock, which had been buried deep inside her, slipping past her cervix and entering her womb for the first time.
