if you didn't know, Lucian is a tsundere. And most of these will start off as one shots so I can compose myself XD. And some will be normal fluffs.
Enjoy!

Narrator's POV:

It was an average day for Cuphead and Lucian. The Gang had went out to do whatever and they had been left alone, with nothing to do. Right now, Lucian was in her room getting dressed in pajamas. And Cuphead was anxiously awaiting her arrival. It's true that Cuphead and Lucian shared a room, but that was merely because there weren't anymore spares. They weren't dating, no, they were only friends, but today Cuphead was secretly hoping to be more than that. "Would she really want to...? Rocky said she does...but...then again...why the hell would I trust her?" Cuphead thought aloud. He let out a annoyed sigh, and slid his back down on the couch.

"Omg where the hell did my clothes go?!" Lucian asked in annoyance. The woman looked around her room in search for the missing pajamas. Did Eliver take them...? She wondered. Eliver was Rocky's "partner in crime" along with Sans, and Lucian wouldn't be surprised if the two girls took her clothes and replaced them, while Sans...watched because he's not a perv and wouldn't go through Luci's stuff.
She searched the drawer.
I think they know not to go in my personal belongings anymore. She chuckled remembering the pay-back the three had gotten after they replaced Lucian's purple Night watch hat. It was a good thing we had that spare hose.
She searched the closet.
Lucian's ears twitched in anticipation. If she didn't hurry up, Cuphead might call it off! Or worse, he might not speak to her! She quickened her checking pace. Why am I so unorganized?! She groaned.
She searched the bed.
Finally she found a note. "The fu...?" She asked.
Note:
Dear Luci,
Your pajamas had vanilla and fudge ice cream all over them after an incident with the kids. It's in the wash and probably won't be clean tonight!

Sorry for any trouble!
Eliver

(P.S: I left some clothes next to the note! Sorry we didn't have many spares...)

Lucian looked at the pajamas next to the note and smacked her forehead. "You've got to be kidding me..." She mumbled.

Where is she? Cuphead wondered. Did she not want to come...? Did she ditch me? He shook his head not believing it.
This was Lucian he was talking about! She would never ditch someone! Without telling them at least. He hesitated before checking his phone, hoping that she didn't call off the movie.

He sighed with relief when there was no text. Then where- his thoughts was interrupted when he heard footsteps. Well not really footsteps but you get the idea. He looked at the stairs and his face engulfed in red. There stood Lucian, the one he had a crush on for a long time.

The cup looked at the woman's clothes, she was wearing a shirt that didn't cover her lower body, she had pink panties and her beautiful purple hair was down. She looks adorable...and hot...shit. He thought blush deepening.
"H-hey!" Lucian's embarrassed voice squeaked. "S-stop staring y-you pervert!" She huffed, purple dusting her cheeks. Cuphead blinked himself from his thoughts and forced himself to look away.

"S-sorry!" Cuphead apologized, his blush deepening. Seriously he looked like 10 tomatoes just smacked him in the face. He looked at the floor, not wanting to face Lucian as she hurried over. The purple woman say on the far side of the couch and didn't face him. They say in an awkward silence for some time.

"A-are you gonna pick a-a movie or not?" Lucian asked glancing at him. Cuphead jolted from the sudden sound of her voice.
"O-oh yeah! Heh heh, I almost forgot about that..." He said awkwardly. He looked through the options that they had. "So what do you wanna watch?" He asked.

Lucian looked at all the movie choices. "I dunno...you choose..." She told at him.
Cuphead shrugged and looked at all the movies. A smirk plastered across his face when he found a certain movie: Fifty Shades of Grey which he didn't even know they had. He put the movie in then plopped down on the couch once more. Lucian eyed his smirk and rose an eyebrow

"What's with the smirk?" Lucian asked him. Cuphead shrugged. "See for yourself miss missy." He told her.

Lucian's POV:
What was he planning? I decided to keep my cool. "Alright fine don't tell me baka!" I crossed my arms and looked at the T.V screen. My blush deepened when the movie came on screen.
"F-Fifty Shades of Grey?!" I exclaimed looking at Cup. Why the hell would he choose that movie?! Why the hell do we even have that movie?!

"You told me to choose, so I did!" Cuphead laughed.
I punched him in the arm. "No way am I watching this!" I told him.
He looked at me with pleading eyes. "Pwease?~" He asked. Shit, I fucking hate when people do that. I sighed in defeat.
"Fine! Baka taco!" I said. "I-it's not like I'll like or anything..." I crossed my arms as he pressed play. The start to the movie was actually kinda ok. But throughout it, I realized that something was up with Cuphead. His hands were on his legs, while his right leg bounced up and down. He was anxious for something...but what? I decided to ignore it. he was probably fine.

Cuphead's POV
I am not ok! Now I can see why Lucian didn't wanna watch this movie! My body is hot...very hot. I glanced at Lucian, she was watching the movie intently. I'm not usually a perv, but in times like these...well...I can't help myself...despite my actions to stop myself my eyes gazed down at her chest.

Her large breasts were hidden under her shirt that stuck to them. My blush grew and I shook my head then looked away, I didn't want to seem like a creep. ...wait...this would be a perfect time to do something! She's distracted! I realized. I scooted closer to her. Nothing. I scooted closer to her again. Still nothing. Finally I found the courage to pick Lucian up and place her on my lap.
It was at that moment.
Where I knew
I messed up.
My eyes jolted when I placed Lucian in my lap. The tsundere gasped and squirmed in the grasp, grinding across my erection. I bit my lip, not wanting to let out a moan. "L-Luci please stop squirming." I pleaded. She stopped, and pouted. "F-fine!" She said. I sighed with relief. That was a close one! My body was still hot as hell though...
This is gonna be a long night...

First part done! Now onto the next one. LEMON WARNING!!!
