I bolted out of that bathroom stall like my life depended on it, pants still half-zipped from the interrupted mess I'd made of myself, heart pounding so loud it drowned out everything else. My legs were jelly but I pushed them anyway, sneakers slapping against the floor as I rounded the corner toward the elevators, because fuck staying in this building one more second with him lurking like some sadistic shadow. The office was empty now, dead quiet after hours, and I jabbed the button over and over, muttering under my breath, "Come on, you piece of shit, open up before he finds me again and turns this into another round of his pervert games."
The doors finally dinged and slid open, empty car waiting like a trap, and I threw myself inside, slapping the lobby button like it was his face. "Take me down, take me away from this nightmare, just get me out," I whispered to no one, leaning against the wall and trying to catch my breath, wiping my sticky hand on my shirt because yeah, that was classy, Ye-jun, cuming in the bathroom like a desperate omega with no self-control. I was still hard, sort of, the ache lingering from thinking about that stupid sketch and his stupid voice calling me pervert like he wasn't the one drawing rope porn on company time.
But of course, nothing ever went my way. A hand shot in right as the doors were closing, yanking them back, and there he was, Si-woo, looking all bossy and arrogant with his shirt still half-unbuttoned from whatever late-night bullshit he'd been doing, eyes narrowed like he owned the whole goddamn building, which, let's be honest, he kind of did. He stepped in, the doors shutting behind him with that final click that made my stomach drop, and without a word he hit the emergency stop, the car jerking to a halt like my whole plan to escape just got cockblocked.
"Running?" he said, voice all low and mean, stepping closer so fast I backed up until my back hit the wall. "From what, exactly? Your own hard-on? Or are you finally admitting you can't handle getting caught with my sketch, you little thief?" be said grabbing my dick so he could feel it and I shoved him.
I laughed, short and panicked. "From you, you sadistic fuck unlock this before someone hears us and thinks the boss is molesting his pouty stepbrother in the elevator. Or is that your next move?"
Crackkkk I received a slap across my face and before I could process it I looked down as dick was so hard it could tear through his trouser. This sadistic fucker got hard from slapping me?
"Slap me around some more like the pervert you are, drawing that kinky shit and getting hard over it" I yelled.
His eyes flashed, that arrogant smirk twisting into something darker, and he was on me in a second, body pressing mine against the wall, one hand grabbing my jaw hard enough to tilt my head back, the other sliding straight down into my pants and straight to my cock like he had every right to touch me whenever he wanted. "Watch your mouth, omega," he snapped, fingers wrapping around my cock, thumb circling the tip slowly and teasing, smearing the leftover slick from my bathroom disaster. "This why you stole my sketch? Needed some inspo for jerking off to your stepbro? Pathetic. Look at you, already leaking again, all cute and pouty like you weren't just running from me."
I bucked into his hand without meaning to, hips jerking forward because damn it, my body was a traitor, reacting to his bossy touch like I was some needy omega programmed for it. "Yeah, because your 'art' is so inspiring," I sassed back, voice cracking but I kept going because talking was the only way I could fight this, pouting up at him with my best annoyed face. "Real pervert masterpiece draw me getting railed next time, add some details like how you'd slap me around while doing it, you sadistic creep. Bet that gets you on, huh? Slapping your cute little stepbrother and pretending it's not because you're obsessed."
He growled low and angry and his free hand came up fast, slapping my cheek not too hard but enough to sting, enough to make my head snap to the side a little. "You talk too much," he hissed, thumb pressing harder on my tip now, circling relentless, edging me slow like he was drawing out every whine. "Keep reminding me of that sketch and see what happens, you mouthy brat. I ought to shut you up right here."
I rubbed my cheek, pouting harder because it hurt but also because I could see it the way his pants were tenting even more now, his cock hard as rock pressing against my thigh like the slap had turned him on, the sadistic pervert enjoying it way too much. "Ow see? You slapped me and now you're even harder, you freak," I whined, talking over him as my hips bucked again, chasing that slow stroke. "Admit it, Si-woo, you're such a sadistic pervert, getting off on hitting your pouty omega stepbrother. What would your Dad say? Or my Mom? Bet that sketch has you tying me up and slapping me silly in your sick fantasies."
His jaw clenched, eyes darkening with that arrogant fury, and he slapped me again, sharper this time, on the other cheek, the sound echoing in the tiny space.
" Ouch," I yelled.
"Shut your fucking mouth," he yelled, but his voice cracked a little, hand speeding up on my cock now, fist tight and pumping just enough to build me up but not let me tip over. "You think you can piss me off like that and get away with it? Beg for it, omega beg like the cute little talker you are, or I'll edge you all night and leave you crying in here."
