Long after Saera had fallen asleep in his bed, Jin lay awake, unable to relax. The throbbing in his loins persisted even after the initial desire faded away. He kept replaying the feel of her skin, the softness of her hair in his hands, and her quiet gasps in his ear - a cycle of torment circling in his mind. He tossed an arm over his face. He'd overestimated his own level of restraint. He couldn't go on like this. He felt like he would never sleep again.
