Kouhei could only watch as Yuuna brought her hand to her lips, licking the cum from her fingers with a slow, deliberate sensuality. He wanted to stop her, a part of him thinking that a girl as beautiful as her shouldn't be tasting something so raw and dirty. But the sight of her doing it—so willingly, so provocatively—ignited something deep within him. His cock twitched, responding to the sheer eroticism of it.
Yuuna, meanwhile, seemed almost caught in the moment herself, licking away every trace, savoring it. When she tried to swallow, she struggled. It was thicker than she'd expected. Her throat bobbed as she gulped, trying to get it down. She swallowed again, and again, until he could see the last of it sliding down, tracing the path from her throat down to her stomach. When she finally looked up at him, she licked her lips, a glint of satisfaction in her eyes.
