It was a game.
I walked along the passage, my hakama billowing about my legs and my coat like blue wings trailing behind me.
And then I turned the corner and slammed the shinigami against the wall by his throat. I looked closely at him, then realize I didn't know his name. Hmmm.
He grinned. "You found me."
"Hide and seek," I replied, before moving my hand down to his chest, all the feeling his rapid pulse flutter against my palm. "Nervous?"
"Nervous. Agitated." He gasped as my hand slid further down and began caressing his abdomen. "And now very, very turned on."
I pulled away completely, amused by his reaction. "Who sent you to spy on me?"
"No one. I just thought you were interestin', that's all."
"Interesting enough to stalk? That's what gets you going?" I pouted. "You are kind of twisted."
"Nothin' compared to ya, vice-captain. Get a guy riled up and not lettin' him release? That's just mean, man."
I smiled and moved a step closer. "This better?" Another step. Another step. "Or perhaps this?"
"You're just being meaner." He inhaled sharply when I finally pressed my body against his, and yet his hands lay flat against the wall.
I placed my hands over his and pushed up against him. He moaned softly.
"I'm twisted like that," I said, my breath now ghosting across his alabaster skin, and chuckled at the pale pink flush suffusing his cheeks. "And I'm starting to get the message that you like twisted."
"Got it in one."
Got to give the rookie props; he dared to face me at this moment. His lips brushed mine and I tingled.
Hmmm. Has potential.
"Sorry, kid, I'm in a committed relationship right now." I let go of his hand and traced my fingers up his arm, then down his face. He bent, just a little, into that tiny caress. My smile grew. "I'm in a steady, rewarding relationship."
He opened his eyes, just a little. "I can seduce you if you want me to, sir."
I lowered my mouth to his ear and flicked my tongue against the lobe, before whispering, "I have to want?"
He stiffened as I kissed him on his petal smooth cheek. Then I let go of him and continued walking to my girlfriend's place, a slow smile curving my lips. Then I caught sight of a silver strand of hair stuck on my chest. I twisted it up and placed it in my private envelope of notes.
He will look for me again.
