Christmas Revenge: Become My Bully's Step-Mum

Emma’s POV I turned the key in the lock and it gave a familiar click, but the sounds coming from inside my shared apartment was far from that. A low rhythmic moan echoed from the hallway, accentuated by the wet sounds of skin slapping skin and a woman’s breathy giggle. My heart jumped. I thought Mark told me he’d be working late again, so what in hell’s name was going on? I crept forward silently, the grocery bags I held crinkling softly, until I reached the bedroom door. It was slightly open, just enough for me to see the heart-shattering pornographic scene. There he was, my boyfriend of two years, Mark, naked and sweaty like a bucket of water had been poured on him. His body glistened under the dim damp light and his muscular back flexed as he thrust deep into a blonde lady sprawled beneath him on our bed. OUR bed! The woman was a stranger to me, she had long legs and fake t**s bouncing with every powerful stroke. Mark’s hands gripped her hips hard enough to leave bruises, pulling her more towards his thick c**k as he growled. “f**k, yeah! Take it all, you slut!” The blonde arched under him, her manicured nails raking down his chest, leaving trails. “Harder, baby,” she purred. “Fill me up like your boring girlfriend never could.” My world turned upside down. The bags slipped from my fingers then, the items I bought rolling across the floor. Mark’s head snapped up, his eyes locking on mine mid-thrust. His reaction surprised me. Rather than guilt or horror, a slow, shameless grin spread across his face. He didn’t stop. If at all, he slowed his pace to a deliberate grind, letting me see every inch of his thick shaft disappearing into the woman’s shaved p***y, her lips stretching around him. “Emma? Perfect timing,” he said, acting casually like I’d just walked in on him watching TV. The blonde twisted to look, her cheeks flushed, lips parted in a moan as Mark shoved into her deeply that made her gasp so loud. “This is Stacy. Met her at the gym, and she’s got a body that actually does something for me.” I stood frozen, feeling the urge to actually throw up. “What the f**k, Mark. Get off her! That’s our bed!” He laughed like I’d just made a joke, pulling out from her just enough to let me see the glistening evidence of their arousal- his c**k throbbing, veined and angry-red, coated in Stacy’s creamy juices, before slamming back in with a wet squelch. Stacy whimpered in pleasure, grinding her clit against him. “Why stop the fun, babe? Don’t be a party pooper,” Mark taunted me, his hips picking up speed again, the bed creaking under the force. “Join us. Threesome’s been a fantasy of mine forever. You could… I don’t know, lick her while I f**k you both. Or just watch and learn how to be exciting for once.” Stacy giggled, reaching down to rub her swollen clit in circles. “Come on, sweetie. I don’t mind sharing. His d**k feels amazing—bet you’d love it up your ass will I sit on your face.” She bucked against Mark, her breasts jiggling, her n*****s hard as pebbles. My face burned with humiliation and rage. How dare he? “Are you serious? You’re cheating on me in our apartment, and you want me to… to join? f**k you, Mark. We’re done.” Mark’s grin faded into a sneer, but he kept pounding into Stacy, his balls slapping against her ass with every thrust. “Done? Please. Look at you- standing there in your frumpy jeans and that shitty ponytail, acting all high and mighty. You’re as dull as dishwater, Emma. No wonder I had to find someone who actually knows how to fuck.” He reached around to pinch Stacy’s n****e, twisting it until she cried out in ecstasy. "Stace here? She deepthroats like a pro, rides me reverse cowgirl till I see stars. You? With those saggy t**s and that flat ass—yeah, you're a solid 4 on a good day. Get out. Pack your s**t and go cry to your mom." Tears stung my eyes, but I refused to let them fall. Stacy moaned louder, clearly turned on by the drama, her p***y clenching visibly around Mark’s c**k as he neared his climax. “Oh god, I’m gonna c*m,” she panted. Mark groaned, burying himself to the hilt. “Me too- gonna pump this tight cunt full.” With a final, brutal thrust, he came, his body shuddering as ropes of hut c*m flooded Stacy. She followed seconds later, squirting a little onto the sheets, her screams filling the room. I backed away, grabbing my keys from the floor. “You’re disgusting,” I whimpered. Mark pulled out with a satisfied pop, his spent c**k dripping as he waved dismissively. “Door’s that way, prude. Don’t come back.” I fled, slamming the door behind me like a final nail in the coffin of our relationship. The night air hit me like ice as I stumbled down the dimly lit street, my phone clutched in my hand. The air did little to soothe the burning humiliation in my chest, or the unwelcome throb between my legs, a twisted reminder of the scene I’d just witnessed. Mark’s c**k, thick and veined, plunging into that w***e’s dripping cunt… God, why did my body react like this? I shook my head, dialing my best friend, Sarah with numb fingers. The phone rang twice before Sarah picked up. “Emma! Hey, girl, what’s up? It’s kinda late.” “Sarah,” I choked out, trying to steady my voice. “I… I need a favor. Can I crash at your place for a bit? Like, tonight? I have nowhere else to go.” There was a pause, then a muffled giggle on the other end followed by a low masculine groan. I realized then that Sarah wasn’t alone. “Oh, hon. I’d love to, but… Jake moved in last month, remember? And well, we’re… you know, f*****g like rabbits every night. Seriously, it’s non-stop. Last night, he bent me over the kitchen counter and pounded my ass until I squirted all over the floor. The walls are thin, and I wouldn’t want you hearing us going at it. His c**k is huge, and I get loud when he chokes me while slamming into my p***y from behind.” Sarah laughed, a throaty sound that sent a shiver through me. “It’d be super awkward for all of us. You get it, right?” I swallowed hard, my mind flashing to unwanted images: Sarah on all fours, her perky t**s swinging as Jake’s thick shaft stretched her tight asshole, his balls slapping against her slick folds. Why was I picturing this? “Yeah, okay. I get it,” I muttered, my voice flat. “Everything alright with Mark?” Sarah pressed, concern edging into her tone amid another distant moan- probably Jake teasing her even now. “He’s fine. Great, actually,” I lied. “Talk later.” I hung up before Sarah could probe further, pocketing my phone and leaning against a cold brick wall. The street was empty, save for the distant hum of traffic, leaving me alone with spiraling thoughts. How had it come to this? I’d poured everything into that damn relationship- every dime from my shitty waitressing job, every late-night shift at the dinner where creeps ogled my ass in those tight skirts. When Mark lost his job a year ago, I’d been his rock, paying the rent, buying his groceries, even sucking him off under the table during his “stress relief” sessions just to keep him going. I’d swallowed his c*m more times than I could count, gagging on his length while he watched porn on his phone, comparing me to the sluts on screen. And once he landed that cushy office gig? The tables turned. He started criticizing my body—the way my C-cup breasts didn’t bounce like those fake-titted bimbos he jerked off to, how my ass wasn’t “firm-enough” for the doggy-style pounding he craved. He’d make me strip in front of the mirror, pinching my n*****s until they ached, mocking my “vanilla” moans while forcing me to finger myself to orgasm just so he could watch and laugh. Now, here I was; broke, homeless, my savings drained into his lazy ass. Where to go from here? A hotel? Too expensive? My family? They’d just lecture me about “wasting my youth on that loser.” The thought made my thighs clench, a slick heat building despite my anger. Fuck, why was betrayal turning me on? I imagined confronting Mark again, but this time, shoving him down and riding his face until he begged for air, grinding my wet p***y against his mouth while Stacy watched, jealous. No- stop it. I needed a plan, not fantasies. Wiping away a stray tear, I straightened up. If Mark thought I was dull, maybe its time to unleash the slut he’d never seen, the one who’d f**k her way to revenge, one throbbing c**k at a time. But first, survival. I glanced at my phone, scrolling through contacts. There had to be someone…
