Light tried, unsuccessfully, to suppress a moan as Ryuzaki's tongue slid down his glans.
"S... Stop, Ryuzaki...," he managed to hiss through gritted teeth. "It's too... ahhh... too intense!" Alternating peaks of pain and pleasure shook his body, beyond his control. Ryuzaki was still too eager. It hurt. The warm caress of the tongue did not stop, but it became gentler. Too late. Light gave in to the irrepressible groan as he felt the fluids rushing through his reproductive system, forcing their way out, out of his body.
Still panting, Light brushed away a few sweaty strands of hair, so he could look at the person that had given him this weird mix of uncomfortable pleasure. "I'm sorry," he said.
Ryuzaki squatted in front of his bed, caught between his thighs. There was some milky semen shimmering on his lips, eventually making its way to the chin. Slowly he touched it with his tongue and licked it away. "Salty..." the detective mumbled, absent-mindedly. Light blushed. "Why didn't you just spit it out. I could've told you it's not sweet," he grumbled. Now that blood kept returning to his brain, the situation got weirder and more embarrassing by the second.
Ryuzaki wiped his mouth with the sleeve of his baggy pullover. Or his pyjamas. Light could not really tell.
"How would you know?" the detective asked, staring at Light's rapidly decreasing erection. "After all, semen contains a certain percentage of sugar." Light wondered how on earth L would know this. It's not like he was an expert on sexuality. Then again, he could just have made it up. He shrugged. "If you say so. You're the expert on sugar, that's for sure."
Ryuzaki grinned. "Still, I have yet a lot to learn. I take it that Light-kun has experience regarding sexual pleasures?" It was more of a statement than a question. Light blushed again and looked away. "Well, yes..." "Good. Then Light-kun can teach me," Ryuzaki concluded contentedly. Light pulled up his pyjama trousers while trying to figure out what plan his friend was pursuing by this suggestion.
