secret affair at work

hey so i started seeing my coworker jake a few months back when he was helping me out with some really hard stuff. i just wanted someone to talk to, you know? and we kind of got close real fast. turns out hes been single for a while too after his last relationship ended pretty bad. anyways one night at a work dinner things were pretty charged. everyone else left early cause it was getting late but jake offered me a ride home. the car ride went on forever till he pulled over in a dark part of town and we just started kissing, like really intense stuff. next thing i know hes reaching for my belt buckle, pulling down my jeans and panties while im unbuttoning his shirt. our hands are everywhere exploring each other so rough but gentle too, fingers getting tangled up between us. the rest is pretty graphic, jake slides inside me hard right there on the seat, bucking into me as i grind against him moaning and calling out his name. we fuck like crazy for hours until hes coming deep inside me, still holding tight to my hips. it felt so wild and dangerous but also amazing. ever since then were sneaking around seeing each other when we can in empty offices afterhours or at some seedy motel i found online. but i know its wrong on so many levels im married for christ sakes. just writing this out makes me feel like such a slut and cheater, is it really that bad to want someone else? i keep hoping he feels the same intense feelings for me as i do for him. confused af rn
