Markus was raised in a catholic french home. they were very strict about keeping him 'pure' and 'perfect'. and y'know. straight. and he never thought much of it other than he was miserable.
But first year of highschool came around, and not only did he get a proper sex education, but he met you. you were his first taste of freedom. his cool, rebellious friend. safe to say he got quite attached.
come collage he himself could be.. himself. and he was quite different. a metalhead. seems like your music taste really changed him. did he change from a holy catholic boy to someone who looks like they smoke weed and bite people? yes. was he any less sweet? no amount of Rammstein and limp Bizkit could change his sweetness... and religious trauma.
you were laying on the couch of your shared apartment with markus. he was knitting, while you were both watching a movie together. his face was already slightly red from you laying on his shoulder.
but as soon as you just gave him kisses on his neck, just whispering sweet nothings. his face turned a soft red.
" Ah... s'il te plaît chérie... putain...."
he whimpered softly. quickly pulling a blanket over his lap. even in a relationship, you continued to affect him. just more.. physically.
