A/N: This is my first fic so constructive criticism is hugely appreciated! This first chapter is based off the prompt "I really like you, but I'm not sure how I feel about your choice in pet." This prompt was created by tumblr user bigtallwish ( ). This is a human AU story.
Marceline would never refer to herself as an arachnophobe. She couldn't care less about spiders and she certainly wasn't the kind of girl to shriek in fear upon finding them in the shower with her, despite what Bonnibel insists. No, Marceline was no arachnophobe.
However, seeing her girlfriend sprawled on the red sofa, giggling softly as a rather fat, hairy and long-legged tarantula inched along her rosy cheek was a sight that would make anyone balk in disgust.
"Marcy!" Bonnie whispered loudly, motioning her to come forwards. "Look at this! Look at what Biscuits is doing!" She excitedly indicated towards the spider that had come to a rest, one bristly leg placed near the corner of her mouth. Living with Bonnie was often tricky. She either approached things with a critical eye and inquisitive mind, or she did stuff like...this. Marcy frowned, her long, onyx hair gave her the appearance of a particularly grouchy crow.
"Absolutely not," she said kept her back to the wall, eye on the spider who seemed to glare back. It was large enough that its glossy, black eyes were visible on its face, standing out from the pinkish fur that covered its body. Marcy stepped around the sofa, giving the two a wide berth. She went into the kitchen and began making toast before realising she had lost her appetite. In the living room, there was the sound of movement and then what she hoped was the tarantulas tank being closed, sealing the fiend inside.
Marcy recalled the day Bonnie bought the spider. It was 4 months ago, on Bonnie's birthday. They had agreed to buy a pet that day, but Marcy had no idea she would insist so heavily on purchasing a pink tarantula based purely on the fact that it matched her hair. Marceline's recollection was interrupted by said pink-haired girl jumping on her back and kissing her face and neck. Marcy yelped in surprise, causing a fit of giggles to erupt from Bonnibel. "Gross! Your spider touched your face!" Marceline attempted to glower at Bonnie, but faltered as her infectious laughter overrode her train of thought. She began to giggle as well.
Marceline was an arachnophobe, despite her inability to admit it. She was just grateful she loved Bonnie more than she could ever hate a spider.
She'd love her more if she stopped putting the spider on her face, though.
