Warnings: these are SFW and NSFW, MDNI below the cut!
SFW
Fox’s love language is physical touch, anytime of the day, you could just be looking at a case at your desk, he would lean over from his desk to feel your hand.
Whenever you steal his glasses he blushes almost uncontrollably, he just thinks you’re so cute.
totally writes you love notes and letters, leaving them around your desk and when you two live together he leaves them around the apartment.
Mulder is a surprisingly protective lover, he’s the sort to put his arms around your waist if another man was ever looking at you, he’d kiss your neck too
You two on a case of some crazy X file and Mulder getting bored in the car and singing along to the radio.
Whenever you feel upset he doesn’t leave your side, like at all
Fox is a super romantic man, he could see you’re cold on a case in the middle of the night and give you his big trench coat that was significantly too big for you.
He absolutely adores when you do his makeup, there’s something about you practicing your makeup on him that he just really thinks your concentration is cute.
The first time Fox realised you had taken his heart was when you got sent to work with him on a case in the middle of nowhere Oregon when you were focused on reading, he just..fell for you.
NSFW
Fox Mulder is a switch. You cannot tell me otherwise.
He likes when you wear his glasses and ride him, it just makes him so hard.
He likes missionary and cowgirl.
He REALLY likes your ass in pencil skirts..
Mulder is a tits man, he just loves squishing them, putting his head on them and obviously putting his cock between them.
You two once had sex in a rental car on a case.
You wanna know why he always wears that long coat? To hide his damn boner when you bend over in a skirt or trousers.
Remember when I said physical touch is his love language, it has two meanings..
He LOVES when you leave hickeys on his neck, people in the FBI don’t really call him ‘spooky Mulder’ when they realise his ‘innocent’ little girlfriend gave him those hickeys.
He absolutely loves when you sit on his lap and when you grind on his lap he just loses it completely.
Sorry guys this is my first time ever writing for Mulder so I hope I did good :)
