my darkest secret

hey so yeah i was feeling super down last week, my partner and i have this thing where we both have open relationships but always respect each others limits. like a real healthy balance of freedom and care for one another. it works well because we’re both really respectful of boundaries. anywho, some girl at work kinda caught my eye, not just as in ‘oh she’s cute’ more like i’ve been craving her. i told myself no but couldn’t stop thinking about how much i wanted her. one night when everyone was out and it was dark outside, i snuck into her office and she let me in. we started talking about our fantasies and yeah, stuff got hot really quick. she’s a bit of a dominant type you know? so after some flirty talk, i knelt down at her desk. i felt kinda scared but also super turned on. she had these tight jeans and a black sweater that hugged every curve. she unbuttoned my shirt and pushed me onto the floor, i let out a little whimper as she straddled me, hands on either side of my head. it was intense, like all this pent up desire just exploded at once. she reached down between us, fingers slipping into my jeans. i gasped as her hand found me, already hard from the buildup and anticipation. i groaned loudly, bucking up to meet her touch - she laughed that low sultry laugh of hers and pulled off my pants quickly. i was so fucking desperate for this. she pushed my face down against the cool floor tiles and spread her legs over mine, guiding me into position with a sharp thrust. it was tight but wet enough for me to slip in inch by slippery inch. she gripped my hair hard as i slid deeper, holding myself back until she loosened up. once fully buried inside her heat, she started riding rough and fast - fucking me fiercely against the cold floor. every slam of our bodies made her moan out loud, fingers digging into my shoulders. it was raw and so intense, this forbidden moment with no rules or limits. i couldn’t hold back any longer after a while, came hard inside her with growls that echoed off the walls. she kept riding until i felt her shudder around me in release too, leaving us both panting on the floor afterward. we didn’t speak much for the rest of the night but it’s been stuck in my mind ever since. this taboo thing happened and now i feel like a real asshole for crossing that line with someone else’s partner even if she seemed into it at the time.
