Fresh || parasite.

Pairing: Fresh Sans x Skeleton! Reader
Prompt: You get possessed by the Fresh parasite under the guise of it 'helping' you - and for the life of you, you can't figure out why.
Type: enemies -> lovers?
Length: 6.2k words
Background: You're a Sans from an unspecified AU (so you get to decide which AU - could be your own if you want!) where monsters have already made it to the surface. You go by (Y/n) just like Fresh goes by Fresh and not Sans. 
Notes: Requested by BoxOfManyThings & others that wanted some Fresh content. | Lil known fact about me: I hate Fresh. Genuinely. I don't just have beef with his stupid hecking parasite, I have the whole cow. Why? I will not be accepting questions at this time. But disregarding all of that, I still think he has good story potential - specifically for an enemies-to-lovers story (hence this one-shot) because I already have all the hate cooked up to pour into my writing. Disclaimer: just because I hate him doesn't mean I'm not gonna do my darndest to make you simp for him lmao

The word 'parasite' had a negative connotation - as it should, since every parasite under the sun took and never gave in any capacity to the host that kept it alive. In fiction, the word is used to denote a slimy creature that a protagonist needs to fight against, and as the protagonist of your very own story, you were fighting your own parasite. It took control of your body, controlling you like a puppet for its purposes like plenty of parasites do in nature, but instead of fear, all you felt was irritation.

'Fuck you,' you thought.

"Hey now, (broseph/brosephine), we've talked about your unradical language," the parasite said, using your teeth to speak as he made you put your hands on your hips, shaking your head at your thoughts. You couldn't control your body, a passenger in your own vessel, but you were still fully conscious of what was going on. Unable to do anything but think, you made that the parasite's problem - because if you were going to be stuck with something else controlling you like this, you weren't going to go quietly.

'And I've told you that you can get bent,' you clapped back, imagining crossing your arms, but your physical body didn't respond. You'd tried taking control back of your body countless times, but you were doomed to be nothing more than a floating consciousness until you eventually lost even that to the parasite. You weren't entirely sure how long the host had left before its mind withered away to nothing, but you were going to make sure it was the longest indiscriminate amount of time the parasite ever went through.

The parasite sighed dramatically, shaking his head. "This would be totes easier if we could vibe together, broski. Why make war when we can make love?" He made a peace sign with his fingers as you mentally gagged.

'Get out of my body and I'll show you love.'

"I want to believe you, my (broseph/brosephine), but we both know your pants are on fire." The skateboard under his feet flipped into the air as he did a trick off the wall of a building, and he made it look effortless as he hung in the air for a solid moment before the skateboard landed back on the pavement and he glided around a small kid just in the nick of time to avoid hitting them.

You scoffed a disgusted 'Careful', which earned a small grin from the parasite. 'Stop smiling, you're not impressive.'

"I could feel it, dude, you thought that one was pretty gnarly." He made finger guns and pointed it at his own head, where you 'resided'. "I'm growing on ya."

'I'll never like you, Fresh,' you snapped.

"Maybe not for a while, but you'll come around, my dude." His smile remained as he pushed his skateboard faster down the sidewalk. You couldn't for the life of you understand what he was doing - you'd been trying to decipher what his play was since the parasite took control of your body but you'd come up empty. You'd gone in circles for days going over what you knew about parasites - what they did to their hosts, what their goals were, how they went about achieving what they were after - but this parasite in particular shattered the norm. It was survival to have a host—you could feel it tapping into your soul energy like a battery as it piloted your body around like a puppet—but what was the benefit to having you? He already had a skeleton host, so why you?
