Birthday treats (Undertaker x reader) (Black Butler)

Part 1

The Undertaker sat there in the dimmly lit room, his elbows on the table and his fingers clasped together as he rested his chin on his hands. A look of clear frustration on his face as he began tapping his foot.
"Still debateing over this birthday business hmm?" said Grell as he sat on the table edge, looking at him curiously.
"You could say that" replied Undertaker, giving the red-haired reaper a slight frown.

Grell shrugged "I suppose you could go with something safe, like flowers or chocolates. Those are always a winner for birthday gifts" he said, thoughtfully, looking at his freshly painted nails.
"Hmm.. I think _(y/n)_'s a little above that" said Undertaker and shook his head.
Grell looked at Undertaker, a smirk on his lips "Hmmm.. of course" he began, leaning towards Undertaker across the table "You could always just, man up and give her what she really wants" he continued sarcasticlly.

Undertaker sat up, staring at the red-haired reaper, his slight frown deepening.
"Oh come on, it's not like it's hard to see" said Grell, standing up and turning to face the silver haired reaper. "That girl yearns for you" he said as he began pacing back and fourth, swinging his hips. "How long have you known _(y/n)_ now?" he asked, stopping and looking at Undertaker.
Undertaker simply rolled his eyes, not answering.
"At least four years isn't it? Coming here regularly, spending all that time together.... and you're telling me you've never noticed?" said Grell and began pacing again "The way she acts when she's with you, when you talk to her. The way she looks at you.. especially when she thinks nobody's looking. She wants you" he continued then looked over at the Undertaker again, waiting for a reaction.

Undertaker sat there, the frown on his face had disapeared and as Grell stared at him, a dark smile slowly crept across the silver haired reapers lips. "Oh I'm aware of that. Very well aware" said Undertaker and stood up.

"Yo-you are?" said Grell, watching him closely.
"Indeed. Why do you think I tease her so?" Undertaker replied, shrugging, a smirk on his face. "And I'm miles ahead of you on that matter, my love obsessed friend" he said, grinning.
"Oh, how so?" Grell asked, a curious smile on his face as he watched the silver haired reaper move across the room.
"Just a little game of cat and mouse. You see, _(y/n)_ isn't exactly the sweet and innocent little thing you think she is." said Undertaker and shook his head.
"Sh-she isn't? but she always seems like such a nice girl to me" said Grell, now feeling rather confused.

Undertaker wagged a finger at him "Oh no, she has a much darker, more devious side. Come now, you don't think I call her my little nymph for her youthful looks do you?" he said with a giggle. "She's quite a teasing little mynx and it's time I turned the tables on this rather dark game of seduction." he continued, a grin on his face.
"Seduction you say?" said Grell, watching the silver haired reaper
"Indeed, and the birthday gift you see, is just a simple leur" said Undertaker in a confident tone.
"Leur?" said Grell, scratching his head.
"Heh heh heh. You wait and see, if it all goes the way I'm planning... by the end of the night, I'll have _(y/n)_ layed out in my best coffin and at my mercy" replied Undertaker and laughed.
"Your.. your going to kill her? but I thought... " said Grell, a shocked expression on his face.

Undertaker stopped and looked at him, raising an eyebrow "What?" he said then shook his head in dis-belief "No you idiot... I'm going to..." he began.
"Oh" Grell inturupted. The red reaper now blushing, a sudden look of realisation on his face. "Oh-ho, so she'll be getting what she wanted after all" he said, giving Undertaker a playful nudge.
"Not exactly" Undertaker smirked, looking at him.

"What do you mean? if she's been.. " asked Grell, curiously.
"I said it was a game of cat and mouse. What makes you think I'm the mouse" said Undertaker teasingly.
"You've been planning this for a while haven't you.. ooh how sneeky" said Grell, grinning.
"Indeed I have. It's just a matter of patiance, the right time. You see, she has to give herself to me willingly" replied Undertaker.

Grell looked at him for a moment "My goodness... you're.. you're really serious about this girl, aren't you?" he said, resting a hand on the silver haired reapers shoulder.
"True I'll confess, but I need it to be..." Undertaker began, his sentance trailing off as he noticed the red-haired reaper smirking at him.
"And you're calling her a tease?! it's clear how she truly feels about you, anyone with eyes in their head can see that. So why not stop playing hard to get you manipulative old git and just give her what she longs for" said Grell, walking up and standing beside the silver haired reaper "It is her birthday after all" he added, giving Undertaker a prod.
Undertaker grinned at him "I told you, patiance".
