"Stop," he had commanded, and Nagisa had licked his lips while looking at him, arousal showing up on both boys' bodies.

"Sorry, Rei-chan... you're just so delicious," he had commented before kissing him, their lips crushing together. "Maybe I should make your blood circulate, maybe you'll feel better," he had continued, smugly, while unbuttoning Rei's pants.

"What...?" The latter had mumbled, but his body had lifted to make the job easier. He had never fucked a vampire, but then again he thought that was not Nagisa's intention. He was kissing, touching, inhaling the scent of his skin on his thighs, muttering something about how nice and firm they were. How he should bite there next time, or how he should get another bit now. He could smell the blood rushing down to Rei's body, especially given his arousal, and eventually Nagisa had given in. He had left small bites all over his thigh, sucking and then licking on the blue-haired male's skin while watching his fingers grasp on the covers, in a mix of lust and fear and maybe a bit of pain.

Nagisa's eyes flickered up to his face, and he saw his lips parted and eyes closed, but he seemed to be exhausted.

"Sorry, I'll bring you a steak," Nagisa finally announced, sitting down. "You stay here." And like that, he had disappeared, beyond the door. Rei had rested for a few minutes, slipping in and out of consciousness, with his body tingling, maybe a principle of nausea twisting his insides a little. But as soon as he opened up his eyes at the smell of fresh meat on a tray, he almost sat up too quickly and fainted. But luckily, all his body did was feed.

"I'm sorry," Nagisa had whined, lacing his arms around the human, and kissing his neck. Now that he wasn't hungry anymore, he was like a little kitten looking for cuddles. Rei grunted, too busy eating to really pay any attention. But after a few bites, he had to notice Nagisa's tongue tracing circles on his skin, with dedication, while his hand travelled down between his thighs and under his underwear. He moaned, and let the chopsticks fall down on the bed, while newly-produced blood was flowing down to where cold, slithery fingers were touching him. His heart had blood to pump again, and his face flushed dark, his thoughts got lost in his own brain while he considered escaping now. But his body remained docile and still, but yet relaxed while Nagisa's mouth travelled around his neck and shoulder, leaving soft, pleasant kisses. Rei let his head nod down, his eyes falling shut, abandoning himself to the sensation of being trapped by this little demon. And when Nagisa pulled him down on the bed, undressing, Rei had shut his brain down, letting sin get into him.

The only downside to this was, now he would feel those bites for days, reminding him of the confused but sweet, morbid feelings that had dragged him down to hell in that evening. And he thought, while staring up at the sun, despite everything he couldn't wait to do it again.
