Warnings for sexiness again!
"That thing that you did with your tongue, and your Nen, when you wrapped it around...where did you learn that?" Hisoka asked as he stared up at the ceiling.
"A prostitute in the Kakin Empire taught me before he died," Illumi said mildly and allowed his arm to brush against Hisoka's. It felt...nice.
"He?" Hisoka asked, turning his head to stare at Illumi's impressively blank face.
"I have no interest in women," Illumi explained. "He paid for me to kill him. I agreed but asked that he taught me everything he knew about sex before I fulfilled my contract. I had not had a sexual partner before him, and you are my first since then."
"I'm flattered," Hisoka said, wondering exactly how long Illumi had spent 'studying' with the man to be able to do the things he could. "I bet he died with a smile on his face."
"He did," Illumi agreed. "My tongue isn't the only place I can run my Nen through," he added, rolling onto his side and running his fingertips down Hisoka's chest. He felt him shudder. "I would be extremely interested in finding out what the results of combining that technique with my needles would be."
Hisoka swallowed. "You want to...I..."
"You said that I could hurt you however I liked," Illumi reminded him. "And, besides, I assure you, the pain will add to the pleasure, and the challenge." He moved closer to Hisoka and slid his leg between his, pressing his knee to the back of his balls. "Don't you want to know if I could make you cum with nothing more than my dick, my Nen and all those beautiful needles?" he breathed.
Hisoka was painfully hard. "Yes," he moaned, looking up into Illumi's pitiless black eyes.
He felt his legs being pushed further apart and the head of Illumi's cock pressing at his entrance. He could already feel the dark, all-consuming desire to destroy, despoil and tear leaking from the man's aura and he moaned. Bucking his hips, he tried to get him to push inside of him. "Illumi...please," he begged, and watched the small twitch at the corners of his mouth, that was, for his lover, the equivalent of his jester's grin. "I need you. I want you, I- That's a big needle."
"It is," Illumi agreed, allowing his tone to mirror Hisoka's suggestive lilt. "Now, be a good boy and stay very still for me." He pushed his cock inside Hisoka's ass in one smooth thrust and felt the man gasp at the intrusion. He concentrated his Nen in the tip and began to rock slowly back and forth inside him. When Hisoka started to whine, he did grin. "Don't move," he whispered and stuck his Nen-laced needle deep into Hisoka's skin.
